Jan Rot heeft een ‘bloedhekel’ aan de Beatles. Marjolein Meijers (ex-Berini An) haat ‘elke noot’ van de Stones. Het is menens tussen An + Jan.
U mag uiteindelijk beslissen wie er beter is...

Root or crown rot normally occurs in older fields where there has been a history of stress, heavy traffic or grazing, poor drainage, fertility and pH problems, previous insect damage, etc. Plants exhibiting crown rot appear stunted and have few stems. Crown rot progresses slowly in the crown and taproot area of the plant. In many situations, crown rot cannot be attributed to a single pathogen. Several fungi (Fusarium spp., Phoma, Pythium, Rhizoctonia) as well as some bacteria, have been implicated in the disease. Often, a complex consisting of several of the pathogens attacks the plant. The way to tell if a plant has the disease is to dig up (not pull up) a plant showing symptoms. Then use a knife to split open the crowns and roots. Healthy tissue should be white, moist, and firm. Rotted tissue usually has a black or brownish- red color, but the color may vary from yellowish to pinkish or gray-Ken Wise
