Problems solved by technology

[0004] The application of chemical agents is the most effective means to control plant pests, but long-term continuous high-dose application of a single chemical fungicide is likely to cause problems such as drug residues, environmental pollution, and pest resistance
Developing new pesticides is often difficult, costly and takes a long time. Therefore, it is one of the fastest and most efficient methods to achieve synergistic effects through reasonable compounding on the basis of existing products.
It is the goal of technicians to develop a compound insecticide with good insecticidal effect and good quick-acting and long-lasting effects, but there are still certain technical difficulties, and such products are rare

Embodiment 1

[0040] Embodiment 1 thrips virulence test

[0041] The toxicity test was carried out according to the proportioning in Table 1, and the results are shown in Table 1.

[0042] Table 1

[0043] Element Proportion LC50(ug / ml) ATI TTI CTC Toxenpyrad - 2.38 100 - - Thymol - 706.6 0.34 - - Toxenpyrad: Thymol 1:0.1 2.34 101.71 90.94 111.84 Toxenpyrad: Thymol 1:0.2 2.11 112.80 83.39 135.26 Toxenpyrad: Thymol 1:0.3 2.05 116.10 77.00 150.77 Toxenpyrad: Thymol 1:0.5 2.85 83.51 66.78 125.05 Toxenpyrad: Thymol 1:1 3.94 60.41 50.17 120.41 Toxenpyrad: Thymol 1:2 6.77 35.16 33.56 104.76

Abstract

The invention relates to an insecticidal composition containing tolfenpyrad and preparations thereof. Active ingredients of the insecticidal composition are the tolfenpyrad and thymol with a ratio of1:(0.2-1). The compound insecticide with the tolfenpyrad and the thymol as the active ingredients has an obvious synergistic effect and good quick-acting and long-lasting effects, is less in dosage ofthe active ingredients, reduces the production cost and use cost, and is suitable for the control of thrips.

Description

technical field [0001] The invention relates to the technical field of pesticide compounding, in particular to an insecticidal composition containing tolfenpyrad and its preparation. Background technique [0002] Fenpyramid is a pyrazole heterocyclic insecticide with a wide insecticidal spectrum and good quick-acting effect. It mainly has contact killing effect, has ovicidal and feeding inhibitory effects, and can inhibit insects from laying eggs. Its mechanism of action is to hinder the electron transfer system complex I in the mitochondrial metabolic system, so that the electron transfer is hindered, and the insects cannot provide and store energy, and gradually die. It belongs to the mitochondrial electron transfer complex inhibitor. [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...
