Problems solved by technology

It is difficult to be truly effective by using silviculture, biological and physical measures. Biological control is greatly affected by climate, weather and other factors, and the effect is unstable and the cost is high.
Using zinc phosphide and other poisonous sticks, the operation procedures are complicated, and it is difficult to implement in large-scale operations; injecting systemic organophosphorus pesticides are all highly toxic pesticides, and the country has now banned their use. Looking for high efficiency, low toxicity, and low price Low-cost pesticide substitutes with special effects on poplar beetles are urgently needed

Embodiment 1

[0036] Example 1: Composition and preparation method of 12.0% acetamiprid·acephate EC

[0037] The percentage by weight (%) of each active ingredient of the main agent of this example is: acetamiprid 2.0, acephate 10.0;

[0038] The weight percent (%) of each component of the auxiliary agent is: solvent, xylene 50.5, benzene 15.0; emulsifier, benzyl complex phenol polyoxyethylene ether 12.0, α-methyl benzyl complex phenol polyoxyethylene ether 9.0; cosolvent , dimethylformamide 0.5; stabilizer, p-nitrobenzoic acid 1.0;

[0039] The above-mentioned weight ratio raw materials are mixed to make emulsifiable concentrate by traditional emulsifiable concentrate processing method.

Embodiment 2

[0040] Example 2: Composition and preparation method of 12.0% acetamiprid·dichlorvos emulsifiable concentrate

[0041] The percentage by weight (%) of each active ingredient of the main agent of this example is: acetamiprid 2.0, dichlorvos 10.0;

[0042] The weight percentage (%) of each component of the auxiliary agent is: solvent, toluene 71.5; emulsifier, calcium dodecylbenzenesulfonate 14.0; cosolvent, pyrrolidone 0.5; stabilizer, p-nitrobenzoic acid 1.5, p-nitrobenzoic acid 0.5;

[0043] After mixing the raw materials in the above weight ratio, the traditional cream processing method is used to make cream.

Embodiment 3

[0044]Example 3: Composition and preparation method of 12.0% acetamiprid trichlorfon emulsifiable concentrate

[0045] The percentage by weight (%) of each active ingredient of the main agent is: acetamiprid 2.0, trichlorfon 10.0;

Abstract

The present invention discloses a pesticide main agent for controlling poplar longicorn and preparation made up by using said pesticide main agent. Said main agent is made up by mixing 2.0-20.0% of acetamiprid and 10.0-40.0% of dichlorvos or trichlorfon or acephate.

Description

technical field [0001] The invention belongs to a main pesticide used for punching and injecting to prevent and control poplar longhorn beetle and the preparation thereof. Background technique [0002] Poplar longhorn beetle is an important borer pest of poplar, willow, elm, maple and other tree species in my country. More than 100 species of poplar longhorn beetle have been reported in China. Due to the hidden life of poplar longhorn beetles, few types of natural enemies, and complex life history, poplar is one of the preferred tree species for afforestation in my country, such as afforestation, windbreak and sand fixation, fast growth and high yield, resulting in sufficient food resources for poplar longhorn beetles. The occurrence area is 600,000 hm 2 about. [0003] At present, the prevention and control of poplar longhorn adopts the comprehensive control strategy. Details are as follows: [0004] 1. Silviculture measures: select excellent varieties such as Zhonglin 4...
