Problems solved by technology

After the pest eats the loyal minister, it will soon have an abnormal molt reaction, stop feeding, and molt early, but cannot complete the molt due to abnormal molt, resulting in dehydration and starvation of the larvae and death

Embodiment 1

[0026] 40% acetamiprid and furanozide suspension concentrate preparation, the distribution ratio of each component is by weight:

[0027]

[0028]

[0029] The preparation process is as follows: high-speed dispersion of acetamiprid and furantenozide, phenylethylphenol polyoxyethylene ether, alkylphenol polyoxyethylene ether, and part of water according to the stated ratio for 30 minutes, and sand milling The machine grinds the mixed material to a particle size of less than 5um, then puts it in the post-mixing kettle, adds ethylene glycol, citric acid, xanthan gum, etc. and stirs evenly to obtain the finished product.

experiment example 1

[0031] Acetamiprid and furafenozide were weighed and prepared in different proportions according to the process of Example 1 to prepare the acetamiprid·furafenozide suspension concentrate with a total active ingredient weight percentage of 40%. See the table below for specific ratios.

[0032] The indoor synergistic bioassay was carried out by the leaf soaking method, and the resistant beet armyworm was selected as the target pest. Each treatment was repeated 3 times, and 60 heads were treated at each concentration. The virulence regression equation of each agent against the resistant beet armyworm was calculated by the probability value method and lethal concentration, use the LC50 value to calculate the co-toxicity coefficient according to Sun Yunpei's method to evaluate the mixed effect, usually showing three types of effects, namely synergistic, additive and antagonistic, when the co-toxicity coefficient (CTC) is greater than 120, it has an increase effect.

experiment example 2

[0040] The indoor synergistic bioassay was carried out by the leaf soaking method, and the resistant cotton bollworm was selected as the target pest. Each treatment was repeated 3 times, and 60 heads were treated at each concentration. For medium concentration, use the LC50 value to calculate the co-toxicity coefficient according to Sun Yunpei's method to evaluate the mixed use effect.

[0041] The results are shown in the table below:

[0042] Table 2 Toxicity test results of acetamiprid and furafenozide compound and single agent against resistant cotton bollworm

[0043] Test drug

[0044] It can be seen from Table 2 that the co-toxicity coefficients of acetamiprid and furantenozide are both greater than 120 within the range of proportion, indicating that both have synergistic effect within this range.

Abstract

The invention discloses a pesticide composition containing acetamiprid and application of the composition. The composition comprises acetamiprid and furan tebufenozide, wherein the weight ratio of acetamiprid to furan tebufenozide is (1-40) to (40-1). The composition is prepared into various pesticide formulations by adding components such as an emulsifier, a cosolvent, an antifreezer, a defoamer, a thickener, a stabilizer and a pH regulator, but preferably, the composition is prepared into an environment-friendly water-based suspending agent preparation; the composition has a synergistic pesticide effect and can delay pesticide resistance of pests and prevent and control various pests such as delphacidae, aleyrodidae, aphides, thrips, diamondback moths, beet armyworms and mites on crops.

Description

technical field [0001] The invention relates to the technical field of pesticide preparations, in particular to an insecticidal composition containing acetamiprid and its application. Background technique: [0002] Acetamiprid is a nitromethylene heterocyclic compound and is a new type of insecticide. Chemical name: N-(N-cyano-ethylimino)-N-methyl-2-chloropyridine-5-methylamine, molecular formula: C10H11Cl N4, molecular weight: 222.68. [0003] The appearance is white crystal, the melting point is 101.0~103.3°C, and the vapor pressure is >1.33×10-6 Pa (25°C). The solubility in water at 25°C is 4200 mg / L, soluble in acetone, methanol, ethanol, methylene chloride, chloroform, acetonitrile, tetrahydrofuran, etc. It is stable in water with pH=7. When pH=9, it will gradually hydrolyze at 45°C and be stable in sunlight. [0004] Acute oral LD50 for rats: male 217mg / kg, female 146mg / kg; mice: male 198mg / kg, female 184mg / kg; acute percutaneous LD50 for rats: male and female &g...
