Problems solved by technology

Due to the long-term use of traditional insecticides, the resistance of tea leafhoppers is getting stronger and stronger, and a single agent can no longer meet the needs of control. Even if the dosage is increased, the ideal control effect cannot be achieved.

Embodiment 1

[0021] Example 1 : In May and September, 2012, respectively, the field efficacy test was carried out in the tea garden of Zhuzhuang Town, Tongbai County, Henan Province.

[0022] Both the May and September trials included the following steps:

[0023] 1. Carry out a special survey of the green leafhopper on tea leaves, and grasp the detailed information on the occurrence range, hazard status and living habits of the green leafhopper;

[0024] 2. Spray the tea gardens with insecticides in May and September respectively, and spray the tea gardens for the second time after an interval of 5-7 days;

[0025] 3. In May and September, the control effect was checked three days after the second spraying of insecticides on the tea leaves. If there is a small amount of tea green leafhoppers, the third spraying was carried out to ensure the control effect.

[0026] The insecticide used in the control process is a mixture of emamectin benzoate and imidacloprid, and their mass ratio is 20...

Embodiment 2

[0036] Example 2 : In May and September of 2013, the field efficacy test was carried out on Yunwu Mountain tea garden in Xinyang City, Henan Province respectively.

[0037] Both the May and September trials included the following steps:

[0038] 1. Carry out a special census on the tea leafhopper, and grasp the detailed information on the occurrence range, hazard status and living habits of the tea leafhopper;

[0039] 2. Spray the tea gardens with insecticides in May and September respectively, and spray the tea gardens for the second time after an interval of 5-7 days;

[0040] 3. In May and September, the control effect was checked three days after the second spraying of insecticides on the tea leaves. If there is a small amount of tea green leafhoppers, the third spraying was carried out to ensure the control effect.

[0041] The insecticide used in the control process is a mixture of emamectin benzoate and imidacloprid, and their mass ratio is 20-40: 10-20; the mass rati...

Abstract

The invention discloses a prevention method for tea lesser leafhopper. The prevention method comprises a series of prevention steps of general investigation, prevention, prevention check and the like, an adopted blended pesticide is composed of two active ingredients with different action mechanisms, the growth peak of tea lesser leafhopper is learned to carry out targeted prevention and special treatment on the tea lesser leafhopper in the stage, so that the prevention time is saved, the labor intensity of workers is reduced, and the number of tea lesser leafhopper is obviously reduced after prevention is carried out for two peaks. Compared with the prior art, the steps are reasonable and complete, the prevention effect on tea lesser leafhopper is good, pesticide applying cost is low, and the used blended pesticide has the advantages that the fast-acting property is high, the persistent effect is long, pesticide resistance is delayed, the residual quantity of the preparation is small, and safety to target natural enemies is safe.

Description

technical field [0001] The invention relates to tea insect pest control technology, in particular to a method for preventing and controlling tea leafhoppers. Background technique [0002] Tea little green leafhopper, also known as leaf springer, floating dust, rattleworm, etc., belongs to the family Leafhopper of the order Homoptera, and occurs frequently in tea areas in Henan, Hubei and other places. The tea green leafhopper overwinters as adults on the old leaves in the lower part of the tea bushes or on the weeds in the tea garden, and the adults start to feed in the early spring of the next year. After the tea leaves germinate, they lay eggs in the epidermis of the young shoots, resulting in damage to the tea transport tissue and insufficient nutrient supply , is a common pest in tea producing areas. The weedy tea garden is prone to this insect. Adults and nymphs are afraid of direct sunlight and usually inhabit the back of young leaves to cause damage. [0003] Tea gr...
