Problems solved by technology

However, the effects of these methods are not ideal under the cultivation conditions of plastic film mulching. The main reason is that the eggs of some small cutworms have been produced on the soil surface or on the weeds in the field when the plastic film is covered. At this time, the effect of sprayin

Embodiment 1

[0014] A method for preventing and treating cutworms under mulching cultivation conditions, the steps are as follows:

[0015] 1) The first step is to clear the field, edge, ridge and surrounding weeds, which can kill eggs, larvae and pupae;

[0016] 2) Use sugar, wine and vinegar liquid or black light to trap and kill overwintering adults, and set up two moth traps per mu to trap and kill adults during the adult occurrence period in spring; the sugar, wine and vinegar liquid is composed of Prepared by mixing sugar, wine, vinegar, water, and trichlorfon;

[0017] 3) For the fields that have passed the trapping and killing period of adults, plow the land first. After plowing, use fresh cabbage leaves to chop, and mix well with 800 times liquid of crystal trichlorfon with 90% fresh cabbage leaf quality. In the evening, every 667 Spread 10 kilograms evenly per square meter, and the land can be leveled and opened after 5 days;

[0018] 4) According to the planting species, open ...

Abstract

The invention relates to the technical field of prevention and control of insect pests, in particular to a prevention and control method for agrotis ypsilon under condition of plastic film mulching cultivation. The prevention and control method for agrotis ypsilon under condition of plastic film mulching cultivation comprises steps of weed removal, trapping and killing of adult pests, land leveling, pesticide spraying of furrow surfaces, film mulching compaction and the like. Missing eggs and larvas of the agrotis ypsilon are totally killed, and damage of the agrotis ypsilon to seedlings is solved thoroughly.

Description

technical field [0001] The invention relates to the technical field of pest control, in particular to a method for preventing and controlling cutworms under the condition of film-covered cultivation. Background technique [0002] The cutworm is the main pest at the seedling stage of spring crops in southern China. Due to its mixed diet, most of the spring crops can be harmed by it at the seedling stage. Through replanting, the uniformity of field seedlings appeared again, and the maturity and harvest time were inconsistent. If it is a landscape scenic spot, the lack of nests and rows caused by the damage of small cutworms will affect the effect of landscape modeling and even fail. The prevention and control of cutworms generally adopt sugar wine vinegar solution to trap adults, artificially catch insects, and spray chemical pesticides for prevention and control when they occur. However, the effects of these methods are not ideal under mulching cultivation conditions. The m...
