　　Some people say that the use of silicone is a double-edged sword. Some people add it to prevent diseases of crops, which will damage the wax layer on the surface of leaves, thus aggravating the occurrence of diseases. Is it true? Why?

　　In general, the emulsifiable oil products should not be added with organosilicon as far as possible. Among the fungicides, azoxystrobin, kresoxim and pyrazoxystrobin have strong permeability, so organosilicon can not be added. Selective herbicides generally do not add silicone because of its unique strong permeability, which may lead to pesticide damage. Fruit trees with thin peel should not be used before bagging after fruiting. Herbicides (glyphosate, glufosinate), added better!
