Control of Schisandra chinensis

Control of Schisandra chinensis leaf curl:

It occurs from July to August, and the larvae are white at first and green later. The first instar insect bites on the mesophyll, and after the 3rd instar, it rolls the leaves to feed, which affects the fruit development.

Prevention and control methods:

① larvae were sprayed with 80% trichlorfon 1 000-1500 times before rolling leaves.

② leaves are rolled and sprayed with 40% dimethoate EC 1000-1500 times.

③ 50% phoxim 1500 times liquid spray.

④ 50% ammonium phosphate EC 2000 times liquid spray.

⑤ larvae can also be captured artificially before and after leaf curling.
