Embodiment 1

[0036] 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.

[0037]

[0038] Theoretical toxicity index (TTI) = ∑ (the toxicity index TI of each single agent × the percentage of single agent in the mixture)

[0039]

[0040] Experimental judgment basis:

[0041] When CTC≤80, the composition exhibits antagonistic effect; when 80

[0042] Various compositions are obtained by mixing 4-p-phenoxyphenoxymethyl-2-ethyl-1,3-dioxolane and cyflumetate in a weight ratio of 40:1 to 1:40, among which The compositions corresponding to several specific weight ratios measure its toxic effect on citrus spider mite, and the test results are as shown in Table 1:

Embodiment 2

[0053] Experimental effect calculation method and experimental judgment basis: the same as in Example 1.

[0054] Various compositions are obtained by mixing 4-p-phenoxyphenoxymethyl-2-n-propyl-1,3-dioxolane and cyflumetone in a weight ratio of 40:1 to 1:40. Wherein the composition corresponding to several specific weight ratios measures its toxic effect on rust ticks, and the test results are as shown in Table 2:

[0055] Table 2 Comparison of virulence test results against rust ticks

[0056]

[0057] Analysis of experimental results: It can be seen from Table 2 that:

[0058] 1) The measured toxicity index of 4-p-phenoxyphenoxymethyl-2-n-propyl-1,3-dioxolane and cyflumetate in the weight ratio range of 40:1-1:40 (ATI) were higher than toxicity index (TTI). Especially in the weight ratio range of 4-p-phenoxyphenoxymethyl-2-n-propyl-1,3-dioxolane and cyflumetate in the range of 4:1-1:4, the ATI is much higher than TTI, indicating that the synergistic effect is obvious....

Embodiment 3

[0065] Experimental effect calculation method and experimental judgment basis: the same as in Example 1.

[0066] Various compositions are obtained by mixing 4-p-phenoxyphenoxymethyl-2-ethyl-1,3-dioxolane and cyflumetate in a weight ratio of 40:1 to 1:40, among which The compositions corresponding to several specific weight ratios measure its toxic effect on root-knot nematodes, and the test results are as shown in Table 3:

[0067] Table 3 compares the virulence test results of root-knot nematode

[0068]

[0069]

[0070]Analysis of experimental results: It can be seen from Table 3 that:

[0071] 1) The measured toxicity index ( ATI) were higher than toxicity index (TTI). Especially in the weight ratio range of 4-p-phenoxyphenoxymethyl-2-ethyl-1,3-dioxolane and cyflumetate in the range of 20:1-1:8, ATI is much higher than TTI , indicating a significant synergistic effect.

[0072] 2) The co-toxicity coefficient (CTC ) are greater than 120, which has obvious syner...

Abstract

The invention provides a pesticide composition containing cyflumetofen and application thereof in preventing and controlling of pests. The pesticide composition containing the cyflumetofen is compounded by the following effective components of a 1,3-dioxolame compound with a 4-p-phenoxymethylate structure and the cyflumetofen. Founded by experiment detection, the pesticide composition containing the cyflumetofen has the advantages that the pesticide effect is obviously higher than the preventing effect of the single insecticide component, so that the usage amount of the pesticide composition is reduced, the resistance risk of the pests is obviously reduced, the use efficiency of the pesticide composition is improved, and the pollution to the environment is obviously reduced while the output of crop is increased; the good market potential and broad application prospect are realized in the field of preventing and controlling of pests.

Description

technical field [0001] The invention belongs to the technical field of pesticide compositions, and in particular relates to a pesticide composition containing cyflumetate 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 ...
