Problems solved by technology

Wheat armyworm uses larvae to damage leaves, tender stems and ears of wheat, etc., causing leaves to form nicks or bite off stems, ears of wheat, or eat up leaves, often resulting in a substantial reduction in production. Most of the production uses chemical pesticides to control wheat armyworm. The introduction of chemical pesticides into the wheat field ecosystem has caused the quality of wheat to decline

Abstract

The invention relates to a method for for preventing and treating wheat armyworm. The method includes ecological treatment by applying Woyiduo or Difulai microbe fertilizer to improve soil physical and chemical properties, and enhance soil fertility and absorption capability of wheat roots; agricultural preventing and treating; biological control; biological preventing and treating; physical preventing and treating; and chemical preventing and treating by spraying 2.5% deltamethrin diluted by 200-2500 times, 90% of crystal dipterex diluted by 800-1000 times or 50% of dichlorvos emulsifiable concentrate diluted by 800-1000 times on wheat plants during nightfall. The method effectively prevents wheat armyworms, and agricultural preventing and treating, physical preventing and treating and other measures are employed to comprehensively control and reduce the average incidence of the wheat armyworm, increase yield, substantially improve wheat level, and obtain good economic benefit.

Description

technical field [0001] The invention relates to a method for preventing and treating wheat armyworm, and belongs to the technical field of plant protection. Background technique [0002] Wheat armyworm belongs to Lepidoptera Noctuidae, commonly known as marching insects, shaving insects, and night robbers. It hosts grain crops such as wheat, rice, millet, and corn, and more than 104 species of plants in 16 families such as cotton, beans, and vegetables. Nationally important wheat pests. The characteristics of the damage are that the larvae eat leaves, and when a large outbreak occurs, all the leaves of the crops can be eaten up, causing serious losses. Because of its flocking, migratory, omnivorous, and gluttony, it has become a nationally important agricultural pest. Morphological characteristics The adult body length is 15-17mm, and the wingspan is 36-40mm. Head and thorax grayish brown, belly dark brown. The forewings are grayish-brown, yellow or orange, with many cha...
