Popis: Endosulfan or Shed-A-Leaf® (sodium chlorate) sprayed on peach trees in autumn significantly reduced the number of overwintering eggs of Myzus persicae (Sulzer), compared with unsprayed trees. However, the effects of the 2 treatments were not significantly different. From inspection of tree bands and leaves, endosulfan was not toxic to phytoseiid mites but was toxic to syrphid larvae. Shed-A-Leaf was not toxic to syrphid larvae, but fewer phytoseiid mites were found under the bands of trees sprayed with the defoliants. These chemical agents could therefore be fitted harmoniously into an integrated program that involves use of these natural enemies in a specific type of orchard of peach trees to suppress the population of green peach aphids.
