Abstract

The invention discloses a medicament used for preventing and controlling celtisasois zhejiangana. The medicament comprises following ingredients, by mass: 50% of moncrotophos, 40% of omethoate, 50% of phosphamidon, 10% of imidacloprid, and 3% of acetamiprid, wherein acetamiprid is diluted to 1500-fold, and the volume ratio of above ingredients is (1-2): (1-2): (1-2): (1-2): (1-2). The formula of the medicament of the invention is reasonable and comprehensive; stomach poisoning effect is excellent and permeation performance is strong; the medicament possesses quick insecticidal effect and special efficacy on injurious insects with drug resistance; dosage is less; activity is high; insecticidal spectrum is wide; killing ability to natural enemies of injurious insects is low; and environmental compatibility is high. Efficacy period of the medicament is long; the resistance of the medicament against celtisasois zhejiangana is enhanced; and the medicament possesses excellent effects in preventing and controlling celtisasois zhejiangana. Application method of the medicament is simple; raw materials are easily available; cost is low; application is convenient, and popularization is easy.

Description

technical field [0001] The invention relates to the planting field of hackberry, in particular to a medicament for preventing and treating hackberry psyllid and its application method. Background technique [0002] Hackberry psyllid is one of the common pests of hackberry, distributed in Anhui, Jiangsu, Shandong (Qingdao) and other places in my country. After the leaves of Hackberry are damaged, long horn-like insect beams will form on the leaf surface. In severe cases, the leaf surface will be deformed, and the insect damage will be scorched, resulting in early leaf fall and weak growth, which will affect viewing in scenic spots. [0003] The Hackberry psyllid has 1 to 2 generations per year, overwintering with eggs in the buds. Around the first ten days of April of the following year, the temperature rises, and when the hackberry first unfolds its young leaves, the eggs begin to hatch, and the nymphs fix and damage the back of the young leaves, and gradually form an o...
