Description

technical field

[0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition containing chlorfenapyr and its preparation. Background technique

[0002] Chlorfenapyr is a new type of pyrrole compound, which acts on the mitochondria of cells in insects, acts through multifunctional oxidases in insects, and mainly inhibits the conversion of adenosine diphosphate (ADP) to adenosine triphosphate (ATP). The drug has stomach toxicity and contact action. The leaf surface has strong permeability, has a certain systemic effect, and has the characteristics of broad insecticidal spectrum, high control effect, long-lasting effect, and safety.

[0003] Thymol: chemical name is 3-methyl-6-isopropylphenol, chemical formula C 10 h 14 O, molecular weight 150.22. It is white to light yellow crystalline powder at room temperature. Thymol has antifungal and parasitic properties and is also commonly used in insect repellents due t...

Examples

Embodiment 1

[0052] Embodiment 1 thrips virulence test

[0053] The toxicity test was carried out according to the proportioning in Table 1, and the results are shown in Table 1.

[0054] Table 1

[0055] Element Proportion LC50(ug / ml) ATI TTI CTC Chlorfenapyr - 3.24 100 - - Thymol - 16.23 19.96 - - Chlorfenapyr: Thymol 1:0.1 2.34 138.46 92.72 149.33 Chlorfenapyr: Thymol 1:0.2 2.71 119.56 86.66 137.96 Chlorfenapyr: Thymol 1:0.3 2.95 109.83 81.53 134.71 Chlorfenapyr: Thymol 1:0.5 3.89 83.29 73.32 113.60 Chlorfenapyr: Thymol 1:1 4.94 65.59 59.98 109.35

[0056] The results in Table 1 show that when the ratio of chlorfenapyr:thymol is 1: (0.1~0.3), the CTC is greater than 120, indicating that within the range of the ratio, the insecticidal composition of the present invention has a synergistic effect, and has a synergistic effect on thistle Horses showed obvious poisonous effect.
