Embodiment 1

[0061] Calculate the toxicity index and co-toxicity coefficient (CTC) of the drug by calculating the co-toxicity coefficient of the compound according to the toxicity index.

[0062]

[0063] Theoretical toxicity index (TTI) = ∑ (the toxicity index TI of each single agent × the percentage of single agent in the mixture)

[0064]

[0065] Experimental judgment basis:

[0066] When CTC≤80, the composition exhibits antagonistic effect; when 80

[0067] Mix 2-chloro-6-((4-phenoxyphenoxy)methyl)pyridine and bifenthrin according to the weight ratio of 80:1 to 1:80 to obtain various compositions, select several specific ones The composition corresponding to the weight ratio measures its toxicity to cotton aphids, and the test results are shown in Table 1:

[0068] Table 1 Comparison of toxicity test results against cotton aphids

Embodiment 2

[0079] Experimental effect calculation method and experimental judgment basis: the same as in Example 1.

[0080] Mix 2-chloro-6-((4-phenoxyphenoxy)methyl)pyridine and bifenthrin according to the weight ratio of 80:1 to 1:80 to obtain various compositions, select several specific ones The composition corresponding to the weight ratio measures its toxicity to armyworm, and test result is as shown in table 2:

[0081] Table 2 Comparison of toxicity test results against armyworm

[0082]

[0083] Analysis of experimental results: It can be seen from Table 2 that:

[0084] 1) 2-Chloro-6-((4-phenoxyphenoxy)methyl)pyridine and bifenthrin have high measured toxicity index (ATI) in the weight range of 20:1-1:80 in toxicity index (TTI). Especially in the weight ratio range of 2-chloro-6-((4-phenoxyphenoxy)methyl)pyridine and bifenthrin in the range of 3:1-1:40, the ATI is much higher than the TTI, indicating that the increase The effect is obvious.

[0085] 2) 2-chloro-6-((4-ph...

Embodiment 3

[0091] Experimental effect calculation method and experimental judgment basis: the same as in Example 1.

[0092] Mix 2-chloro-6-((4-phenoxyphenoxy)methyl)pyridine and bifenthrin according to the weight ratio of 80:1 to 1:80 to obtain various compositions, select several specific ones The composition corresponding to the weight ratio measures its toxicity to diamondback moth, and the test results are as shown in table 3:

[0093] Table 3 Comparison of the toxicity test results of diamondback moth

[0094]

[0095] Analysis of experimental results: It can be seen from Table 3 that:

[0096] 1) 2-Chloro-6-((4-phenoxyphenoxy)methyl)pyridine and bifenthrin have high measured toxicity index (ATI) in the weight range of 20:1-1:80 in toxicity index (TTI). Especially in the weight ratio range of 2-chloro-6-((4-phenoxyphenoxy)methyl)pyridine and bifenthrin in the range of 3:1-1:40, the ATI is much higher than the TTI, indicating that the increase The effect is obvious.

Abstract

The invention relates to an insecticidal composition and an application thereof in pest control. The insecticidal composition comprises a component A and a component B, wherein the component A is selected from any one or a combination of two of 2-chloro-6-((4-phenoxy phenoxy)methyl)pyridine and 2-chloro-5-((4-phenoxy phenoxy)methyl)thiazole; the component B is an esbiothrin compound; and the weight ratio of the component A to the component B is 80:1-1:80. The insecticidal composition has the advantages that two compounds with different action mechanisms are compounded, so that the resistance of pests to the component A is delayed, and compared with the single action of the component A and the component B, the insecticidal composition has a wider action range and improves the insecticidal efficacy; the generation of drug resistance of pests is delayed, the use frequency is reduced, the use amount of the insecticidal composition is reduced, and the agricultural cost of the insecticidal composition is reduced; and compared with other pesticides, the insecticidal composition has lower residual quantity and is more environment-friendly.

Description

technical field [0001] The invention relates to the technical field of pesticide compositions, in particular to an insecticidal composition and its application in pest control. Background technique [0002] The use of pesticides has a very long history. It has played a huge role in the process of human transformation of nature, promoted the great development of agriculture, and brought huge economic benefits to human beings. From the 7th century BC to the 5th century BC, China used mangcao, mirage ash, and peony to kill pests. Before the 1940s, the era of natural and inorganic medicines was dominated by natural medicines and inorganic compound pesticides; from the beginning of the 20th century, it entered the era of organic synthetic pesticides. The current development situation of pesticides: Developed countries have entered the renewal of varieties since the 1970s, and my country's pesticides have developed greatly since the 1980s, but most of them were established and de...
