Abstract:

Grape is easy to be infected with fungal diseases in the process of planting. Even though there are large number of registered fungicide products, unregistered fungicides have still being used or recommended to control grape fungal diseases. And whether their application would cause harm to the vineyard environmental organisms should be paid enough attention. In this study, the fungicides, i.e., triadimefon, diethofencarb, tetraconazole, isopyrazam and vinclozolin, which have not registered but detected or proposed to use on grape, were selected to conduct primary risk assessment to environmental organisms including birds, bees, non-target arthropods and soil organisms. The results showed that the long-term risk quotient (RQ) values of triadimefon and tetraconazole for birds were both greater than 1, which meant the risks to birds were unacceptable. The RQ values of diethofencarb for predatory non-target arthropods were greater than 5, revealing the unacceptable risk of diethofencarb to predatory non-target arthropods. The risks of isopyrazam and vinclozolin to the several terrestrial organisms were both acceptable. This study could provide reference for the scientific application of the selected fungicides on grapes and the subsequent pesticide registration.
