Clopyralid uptake of contaminated compost‐fertilised corn

摘要：

It has been reported ( Sato, 2006 ) that the cases uncertain cause abnormal growth in horticultural crops ( e.g.. tomato eggplant) is generated.In the present investigation, clopyralid (3,6‐dichloropyridine‐2‐carboxylic acid, Figure 1) was detected in cow excrement compost and its materials feeds.Clopyralid is not registered as an agricultural chemical in Japan.It is uncertain how the chemical was detected in Japan despite not being used.Graminaceous plants have low sensitivity for clopyralid.So, there is the possibility of circulation in the food chain ( i.e.imported feed‐cattle‐fescue‐compost‐corn).To clarify the likelihood of the circulation, the effect of fertilizing a clopyralid‐contaminated compost on the clopyralid uptake of corn was investigated someone two different soil types.
