This book defines "weed" as:
A plant growing where it is not desired. Any plant that is a nuisance, hazard, or causes injury to human, animals, or the desired crop.
In other words, it is a political term.
This book is about using pesticides and herbicides.

Some areas (plots) are infested with palmer amaranth, others less so. Effective weed control for a grower requires understanding of weed biology and using different modes of herbicide application. Researchers at University of Delaware study many different herbicide combinations, time of day, rotation, etc. The results of these tests are conveyed to Certified Crop Advisors through Delaware Cooperative Extension field tours, such as this one.

First planting of tomatoes on plastic film. The bare soil between rows will be covered with straw for weed control. A similar set of rows in the back field will be cultivated on the edge of the plastic and flame weeded in between (not too close to the plastic).
This hardy, fast-growing plant is on the hit list of weed control efforts around the globe. It's an aggressive, exotic invasive species that quickly takes over roadsides, stream banks, and other areas, excluding native species and dramatically reducing biodiversity. The plant was at one time popular as an ornamental. These days, intentional or accidental introduction of the plant has been banned in many European countries and in many states and counties in the United States. Here's one exotic that many would like to be without!

I had originally set the tractor wheels as close together as the would go in order to get the most rows onto the field. We have recently been using more plastic film for weed control and to warm up the soil in the spring. The wheel spacing was too narrow to go over the plastic for cultivation without damaging the plastic. So I had to move the wheels out.
The wheels are designed to be mounted in any of four positions, so there are eight possible wheel spacings. The note shows one of the flanges mounting the tire to the hub. The narrowest spacing is when the tire is mounted on the inside of the hub (using the bolt hole on the right in the note). Here I have moved the wheel out one notch. I did the same on the other side. That changes the spacing by about 2.5 inches on each side, 5 inches total.
To get the other two positions, the hub is also removed and turned around. It has a slight dish shape inward here. Moving it so the dish is outward gives you the other two positions.
Moving the wheels was fairly simple, but aligning the front wheels afterwards took two days.

SF Bay RR, 21 June 2018
The San Francisco Bay RR operates on the southeast side of San Francisco on and near the port. It uses two Alco S2 switchers that were built for the State Belt RR, later the San Francisco Belt RR, the line that served the piers of the Port of San Francisco for many years.
As shipping companies moved to containerization, the Port of Oakland became the big northern California container terminal and most of the piers of the Port of San Francisco were abandoned or converted to uses other than marine freight, so the SF Belt RR found itself out of a job. After 1989 Loma Prieta earthquake damaged the Embarcadero Freeway, which had run over the SF Belt for most of its length, the freeway was removed, opening up San Francisco's waterfront and much of the Belt's trackage as converted for use by the Muni F line, which runs historic streetcars to Fishermen's Wharf, and the Muni lines that now server the Caltrain station.
Meanwhile, Pier 96, near Hunter's Point was converted to a container facility and the railroad's operations survived there. The line was renamed the San Francisco Bay RR and continued to use Alco S2s 23 and 25 to switch its customers.
Today, the railroad's main business is transloading dirty dirt from constructions and clean up sites in the Bay Area from trucks to railcars. It is owned by Waste Solutions Group, which also owns a fleet of hopper cars. The SF Bay and UP interchange on an as needed basis, with UP's South City job running into the SF Bay's yard on Cargo Way with empties and taking away loads.
A couple of railfans, Ryan and Ben, work for the railroad and Ryan invited me to come by for a visit. I had stopped by one afternoon a couple of years ago, and lucked out to see an S2 running around the yard a bit, but the railrroad usually goes on duty betweeen 4 and 5 am, switches cars for a few hours and then is done for the day. So, a visit to the SF Bay from Sacramento entailed a night in a hotel. It took a few tries for me to get time off from work scheduled on the same day the railroad was running.
Eventually, it all lined up and my alarm went off at 0315 at a hotel in Daly City, just south of the SF city limit.
I was at the yard by 4 and met Ben, who went out and started Alco 23. 25 is out of service with a bad bearing on the radiator fan drive shaft. Ryan explained that the SF Belt had done a jerry rigged repair of the shaft at some point and it was never documented, so nobody knew about the bearing until it failed. As a new low emission unit will be delivered in the next few months, there is no reason to repair 25. 25 will be put on display somewhere, perhaps near the Ferry Building, while 23 will be held as backup for the new unit.
But for now, an S2 built in 1944 is doing the job it was built to do. If you think about it, that is as though the Virginia and Truckee had still been using the Reno and Genoa during WW2.
Shorty after I got there, Ben went out and fired up the 23. It has a block heater, so it started easily with a puff of white smoke. He did an inspection of the engine, including checking the journal boxes. We then went back into the office and waited for Ryan, brakeman Johnny, and engineer Nick to arrive. The crew plotted their switching moves for the day. Ryan, who is yard operations manager, suggested that I get some blue hour photos from the ground as empties were switched and then we rode 23 while they switched loads.
Each car has dirt from one particular construction site and the dirt from sites cannot be mixed as different sites will have different contamination. UP ships it to a dump site in Nevada, where it is processed. Ryan explained that sometimes they can use dividers in a car to separate dirt from different projects if there is not that much.
Right now transshipping dirty dirt is the SF Bay's only business, but there a couple of other industries are interested in bringing new business. The line that crosses the Illinois St. bridge has been out of service for a couple of years as there currently no customers north of Islais Creek.
We rode the S2 for a while after the day brightened, then got down and Ryan drove me around in a company car to get some more angles as they switched. He then had other work to do and I shot the end of 23's work day as well as 25, some spare Alco parts and another project of Waste Solutions, goats that are leased out for natural weed control. Ryan said that since Waste Solutions got more cars, they can't use their goats as much for weed control in the yard as most of the yard tracks are occupied.
The crew called it a day for switching about 0800 and then would be doing other work in the yard for the rest of their work day.
All of these photos were taken with permission after signing a release and while wearing required PPE.
I want to than Ryan, Ben, Johnny and Nick for their hospitality. I had a great time.

For proper installation and proper root growth, special care and attention to detail should be observed. You can't just blow it u there's more to it than that in Sod Replacement
AR Maintenance Solutions in Lauderdale Lakes Removing old grass, plants and weeds under the grass root carpet is the first step. You cannot put grazing on the old grass. 2) Rebuild the substrate, adding fresh top layer will help replenish nutrients, support water absorption and increase root growth. 3) Leveling is required to determine varieties and ensure proper water separation to maintain. It is also used to remove high spots and fill the low places that remain moist or make the grass cut too short. 4) Nutrients/fertilizers can be added to support the grass root faster, but it is not always necessary. Be careful with fertilizers, they can cause burns to humans and plants if used incorrectly. 5) Donate - Install the new crack in parallel grain direction with latch, driveways or fences. The special practice of staggering parts is to ensure tighter seams and fewer gaps. This also makes it more resistant to animals and insects. 6) watering. If the new Lawn Correct is going to root correctly, the water must penetrate into the surface of the rollers and actually pass to the top layer of the soil below. If the watering requirements are met, the rough is guaranteed for 30 days. You will know when the crack will have enough water if the soil under the root carpet is constantly wet. It can be hard to know when there is enough water. A soil irrigation system is very useful because it can add water automatically if necessary

Wherever possible, we like to retain native grasses and shrubs that act as buffers to weed invasion at the bushland-pasture interface. Here we have been largely successful. In the places where we have not, we will have to stand by with herbicide to remove weedy competition from regenerating native plants if necessary. Careful monitoring will be necessary.

Invasive plant species Canada Thistle in Western SD. This invasive species is spread via vehicles, humans, or animals. Once this weed is on the site, it spreads by seeds or rhizomes and will take over a pasture or meadow. It lowers the plant community diversity and degrades wildlife habitat. Biocontrol insects are available to use on Canada Thistle. Canada thistle is listed as a state noxious weed in South Dakota.
Conservation practice 528, Prescribed Grazing, can be used to maintain healthy rangeland and favor grass growth. Few thistles occur where grazing is managed and overgrazing is prevented. Livestock will graze on thistle when it is young and green. Additionally, concentrating animals for high-intensity-short duration grazing during bud stage, before thistle plants flower, will help to control thistle.
Conservation practice Herbaceous Weed Control (315) can also be utilized to control thistle. Mechanical mowing/clipping, biological insect control, and chemical spraying can all be used as part of the 315 Herbaceous Weed Control practice.
Canada Thistle affects grassland, forest, and riparian areas.
Resource Concern: Plant Pest Pressure
Excessive damage to plant communities from pests such as undesired plants, insects, diseases, animals, soil borne pathogens, and nematodes. This concern addresses invasive plant, animal, and insect species.
Resource Concern: Plant Structure and Composition
Plant communities have insufficient composition and structure to achieve ecological functions and management objectives.
Degraded plant composition occurs when there is a lack of diversity of plant species within a geographic area or an imbalance in the relative abundance of plant species. Degraded structure refers to plant density, distribution patterns, or height and layering that is not suited to providing the desired conservation benefits and products.
Resource Concern: Terrestrial Habitat for Wildlife and Invertebrates
Quantity, quality or connectivity of food, cover, space, shelter, and/or water is inadequate to meet requirements of identified terrestrial wildlife or invertebrate species.
Perhaps the greatest threat to wildlife is habitat loss through lack of management, invasive plants, and habitat conversion or destruction. Habitat dependent organisms that lack adequate tree, shrub, or herbaceous plant cover necessary for mating and nesting, or shelter and cover for nesting, feeding, and resting will not thrive.
Although thistle may serve as a food source for some insects and provide seed to some bird species, it has a negative impact on wildlife habitat quality. Canada thistle grows in dense patches and reduces the vigor and establishment of grasslands and riparian areas.

He did an inspection of the engine, including checking the journal boxes. We then went back into the office and waited for Ryan, brakeman Johnny, and engineer Nick to arrive. The crew plotted their switching moves for the day. Ryan, who is yard operations manager, suggested that I get some blue hour photos from the ground as empties were switched and then we rode 23 while they switched loads.
Each car has dirt from one particular construction site and the dirt from sites cannot be mixed as different sites will have different contamination. UP ships it to a dump site in Nevada, where it is processed. Ryan explained that sometimes they can use dividers in a car to separate dirt from different projects if there is not that much.
Right now transshipping dirty dirt is the SF Bay's only business, but there a couple of other industries are interested in bringing new business. The line that crosses the Illinois St. bridge has been out of service for a couple of years as there currently no customers north of Islais Creek.
We rode the S2 for a while after the day brightened, then got down and Ryan drove me around in a company car to get some more angles as they switched. He then had other work to do and I shot the end of 23's work day as well as 25, some spare Alco parts and another project of Waste Solutions, goats that are leased out for natural weed control. Ryan said that since Waste Solutions got more cars, they can't use their goats as much for weed control in the yard as most of the yard tracks are occupied.
The crew called it a day for switching about 0800 and then would be doing other work in the yard for the rest of their work day.
All of these photos were taken with permission after signing a release and while wearing required PPE.
I want to than Ryan, Ben, Johnny and Nick for their hospitality. I had a great time.
Somebody in NIR has raided the back of the corporate sofa and found enough small change to hire the CIÉ weed control train for the 1979 spraying season. Seen leaving Whitehead in the hands of 186, I think this is a more modern version of the train observed at Lisburn in June 1977 (www.flickr.com/photos/152343870@N07/39299742024/in/dateta...) except for the last vehicle.

Chicago Burlington & Quincy Railroad weed control train with NALX 115 on the front, CB&Q GP7 242 on the rear, and Waycar 14672 carrying the markers, at Naperville, Illinois on July 8, 1963, photograph by Chuck Zeiler. The switcher on the right was the East End Way Freight, which was switching in Naperville as the weed train passed. Here are some definitions from Pete Hedgpeth:
First let's define terminology regarding weed control. There seems to be some confusion as to what machine does what..Here's what we have.
There is: The WEED BURNER - This is a machine described by some as a rail mounted "Flame Thrower". It is usually fueled by diesel fuel and/or gasoline. It's operated as a piece of MOW equipment looking like a couple of push cars with piping carrying burners at their ends directed downward toward the track. The machine was pushed by a motorized machine like a motor car. The pressurized fuel is directed through the down-directed burners and burns with great heat and intensity, incenerating everything on the track over which it passes. This includes ties and, hopefullly all vegetation. I don't think this kind of equipment is used much, if at all, today.
Then there is the WEED MOWER, which also is a track mounted push car-like device with cutter sickle bars which extend out 4 or 5 feet on each side of the track. The sickle bars are usually powered by small "lawnmower" type engines which operate the cutter arms. This equipment is pulled by a track motor car. Probably mostly used on branch lines where the vegetation grows right up the the tie ends on each side. We used this kind of equipment on the Rock Port Langdon & Northern. It was borrowed from the CB&Q when it was needed.
Next is the WEED SPRAY TRAIN. That's what we are talking about here. It's a boxcar like "spray car" with a window-like opening on the "business end" and equipped with a gasoline engine which powered mixing and pressurizing equipment to mix the "chemical" with water and force it through the sprayer bars which run crosswise of the car at about coupler height on the front and below the window. The spray train consists from the front. The spray car and related equipment were followed by a number of tank cars carrying the chemical and water. This whole string is SHOVED by an engine and usually a WAYCAR is behind the engine.
Another ROW maintenance train, not to be confused with weed control, is an oiler. I'm also familiar with why this was done. Brine "drippings" from ice reefer cars created rust and corrosion on the eastbound track on railroads over which they traveled. We had the same situation on the Rock Island between Silvis and Blue Island. Also, it was a big problem on the Government Bridge over the Mississippi River at Rock Island. There, a tar like substance was applied to the eastbound main to prevent, or at least minimize, the effect of the brine.

Dr. Jim Brosnan from the University of Tennessee begins his presentation about control of weeds in warm season turf at the Sustainable Turfgrass Management in Asia 2011 conference at Thailand
Early in the 20th century, huge swathes of land in Queensland and New South Wales had been rendered unsuitable for farming due to an infestation of the prickly pear cactus.
Prickly pear plants were prized as a food source for cochineal insects, which produced a bright red dye when crushed. In the late 18th century, Sir Joseph Banks suggested that New South Wales might prove a suitable climate for establishing a cochineal dye industry. The insects soon died, but the prickly pear plants survived and thrived, particularly to the west of the Great Dividing Range. It overwhelmed native vegetation and farming land and it is estimated that by the early 20th century prickly pear had overrun more than 24 million hectares (60 million acres) across New South Wales and Queensland.
In 1886 the New South Wales Government passed the Prickly-pear Destruction Act. Landowners became responsible for the plant’s destruction, and government-appointed inspectors oversaw the law’s enforcement. However, the Act could not stop the prickly pear infestation.
In Queensland, the government looked to innovation to solve the problem. A £5,000 reward was offered for an effective method of destroying the plants. Suggestions came from around the world and included salt, prairie cattle, steamrollers, arsenic, electricity and a machine that used mirrors to focus the sun’s rays to burn the prickly pear. None of these techniques worked and the bounty was never claimed.
Fortunately, as a result of the government’s research into the management of cacti in North and South America, a potential solution was found. The Cactoblastis cactorum moth was introduced in 1926 and by 1933 an estimated 80 per cent of the infested land in Queensland had been cleared of the pear. The release of the moths is regarded as one of the most impressive examples of biological weed control in the world.

Summer prescribed pasture fires move slower, and leave more post-burn residue; however, summer burning has proven to provide better weed control, especially with sericea lespedeza.

SF Bay RR, 21 June 2018
The San Francisco Bay RR operates on the southeast side of San Francisco on and near the port. It uses two Alco S2 switchers that were built for the State Belt RR, later the San Francisco Belt RR, the line that served the piers of the Port of San Francisco for many years.
As shipping companies moved to containerization, the Port of Oakland became the big northern California container terminal and most of the piers of the Port of San Francisco were abandoned or converted to uses other than marine freight, so the SF Belt RR found itself out of a job. After 1989 Loma Prieta earthquake damaged the Embarcadero Freeway, which had run over the SF Belt for most of its length, the freeway was removed, opening up San Francisco's waterfront and much of the Belt's trackage as converted for use by the Muni F line, which runs historic streetcars to Fishermen's Wharf, and the Muni lines that now server the Caltrain station.
Meanwhile, Pier 96, near Hunter's Point was converted to a container facility and the railroad's operations survived there. The line was renamed the San Francisco Bay RR and continued to use Alco S2s 23 and 25 to switch its customers.
Today, the railroad's main business is transloading dirty dirt from constructions and clean up sites in the Bay Area from trucks to railcars. It is owned by Waste Solutions Group, which also owns a fleet of hopper cars. The SF Bay and UP interchange on an as needed basis, with UP's South City job running into the SF Bay's yard on Cargo Way with empties and taking away loads.
A couple of railfans, Ryan and Ben, work for the railroad and Ryan invited me to come by for a visit. I had stopped by one afternoon a couple of years ago, and lucked out to see an S2 running around the yard a bit, but the railrroad usually goes on duty betweeen 4 and 5 am, switches cars for a few hours and then is done for the day. So, a visit to the SF Bay from Sacramento entailed a night in a hotel. It took a few tries for me to get time off from work scheduled on the same day the railroad was running.
Eventually, it all lined up and my alarm went off at 0315 at a hotel in Daly City, just south of the SF city limit.
I was at the yard by 4 and met Ben, who went out and started Alco 23. 25 is out of service with a bad bearing on the radiator fan drive shaft. Ryan explained that the SF Belt had done a jerry rigged repair of the shaft at some point and it was never documented, so nobody knew about the bearing until it failed. As a new low emission unit will be delivered in the next few months, there is no reason to repair 25. 25 will be put on display somewhere, perhaps near the Ferry Building, while 23 will be held as backup for the new unit.
But for now, an S2 built in 1944 is doing the job it was built to do. If you think about it, that is as though the Virginia and Truckee had still been using the Reno and Genoa during WW2.
Shorty after I got there, Ben went out and fired up the 23. It has a block heater, so it started easily with a puff of white smoke. He did an inspection of the engine, including checking the journal boxes. We then went back into the office and waited for Ryan, brakeman Johnny, and engineer Nick to arrive.

Tom Jesch, owner of Waterwise Botanicals Nursery, demonstrated cactus planting without wearing protective gloves. These are the steps to pain-free planting:
1. Dig a hole, matching the depth to the soil depth in the pot.
2. Lay cactus plant sideways on the ground with the bottom of the pot right next to the hole.
3. Press on the pot a bit to loosen the root ball and pull the pot off.
4. Using a big ol' stick (or any conventional tool) push the cactus into the hole.
5. Do a bad job backfilling the hole around the root ball. Leave lots of voids and air spaces. The soil will fill in properly on its own with irrigation or rainfall.
6. Although cactus thorns are painfully obvious, Opuntia cactus are noted for also having glochids, tiny barbed hairs that are hard to see but can be irritating and painful in the skin. He recommends using duct tape or Brazilian-type hair wax to remove them.
Tom gave these tips for growing cactus outdoors in Southern California and similar climates:
1. Unless you are planting in heavy clay, soil amendments are not needed or recommended.
2. Cactus like to be fed. Expensive fertilizers are not needed. Use regular turf grass fertilizer. Soil in So Cal is naturally rich in phosphorous, potassium and iron so mainly nitrogen is needed. Don't place the fertilizer too close to the plants; apply in the open spaces between plants. Cactus have fine surface roots that spread widely.
3. Tom thinks mulching is a good idea but not right up against the plants.
4. Overhead sprinkler irrigation is much better than drip irrigation, which usually causes rot in succulents. Cactus don't need much irrigation. A few times from spring to early summer is fine. The best way is to irrigate two consecutive days for each watering. The first irrigation opens up the soil surface and the follow-up penetrates deeply.
5. Weeding can be a painful issue around cactus. Tom suggested long BBQ tongs or a really long knife to slice off weed roots. He also recommends weed control with glyphosate (e.g. Roundup). Cactus are fairly resistant to this herbicide and a drop or two won't hurt them.
