Pest control cleansing oil is a new type of antibiotic insecticide and acaricide produced by Shanghai Nongle Biological Products Factory. In order to explore its control effect on the diamondback moth, this year we conducted a field efficacy test. The report is as follows: I. Materials and methods (a) for the test agents: ① pest control cleansing oil (1% 7051 insecticide EC), Shanghai Nong Le Biological Products Factory production; ② 5% card death grams concentrate, Company production; ③ 50% Po Road WP, Switzerland Novartis production; ④ 50% phoxim EC, Nantong dyeing plant production. (B) treatment settings: ① pest control clear 30ml per acre; ② fire insects per acre 40ml; ③ pest control clear 50ml per acre; ④ pest control clear 20ml per acre + phoxim 30ml; ⑤ card dead grams per mu 40ml; ⑥ Po Road 40g per acre; ⑦ no pesticide control. The treatments are arranged randomly and repeated 3 times. (C) Test Method: The experiment was carried out in the cabbage field of the workers and peasants in Dongtai town. May 15 (Plutella xylostella second-term larval period) according to the amount of water watered 50kg, spray evenly using a manual sprayer. Before spraying, we selected 6-7 cabbages per plot to investigate the diamondback moth
