Problems solved by technology

However, the abuse of pesticides has made pests more and more resistant to pesticides, resulting in a decrease in the effectiveness of pest control year by year.
Many chemical pesticides remain in the environment and cause pollution to the environment. Therefore, there is an urgent need for newer, more efficient, safer and more environmentally friendly pesticide products

Embodiment 1

[0028] Weigh tebufenfen (N-(4-tert-butylbenzyl)-4-chloro-3-ethyl-1-methylpyrazol-5-ylcarboxamide) and epoxy Chlorpyrid, add sodium lauryl sulfate, calcium lignosulfonate, white carbon black, dipotassium hydrogen phosphate, soluble starch and kaolin, etc., mix with airflow and pulverize, add water and knead, then add to a granulator for granulation. Then dry and sieve to obtain water-dispersible granules containing tebufenpyrad and cyclopyridam in a weight ratio of 1:1.

Embodiment 2

[0030] Weigh tebufenfen (N-(4-tert-butylbenzyl)-4-chloro-3-ethyl-1-methylpyrazol-5-ylcarboxamide) and epoxy Chlorpyrid, add sodium lauryl sulfate, calcium lignosulfonate, white carbon black, dipotassium hydrogen phosphate, kaolin, etc., mix evenly, and then pulverize in a jet mill to obtain pyridine with a weight ratio of 4:1. Wettable powder of micarid and cyclopyrid.

Embodiment 3

[0032] Weigh tebufenfen (N-(4-tert-butylbenzyl)-4-chloro-3-ethyl-1-methylpyrazol-5-ylcarboxamide) and epoxy Chlorpyrid, add sodium methyl naphthalene sulfonate formaldehyde condensate, white carbon black, xanthan gum, ethylene glycol and water, etc., mix evenly, and obtain tebufenpyrad and cyclic compound with a weight ratio of 8:1 after high-speed shearing. Suspension concentrate of oxypyridin.

Abstract

The invention provides an acaricidal composition of tebufenpyrad and cyclopyrid, comprising tebufenpyrad and cyclopyrid, and the mass ratio of tebufenpyrad and cyclopyrid in the composition is 80:1 ‑1:80. The tebufenpyrad and cyclopyrid acaricidal composition can enhance the activity against harmful mites by compounding tebufenpyrad and cyclopyridam, compared with using the two components alone, in the case of reduced dosage Under this condition, comparable or better control effects can be obtained.

Description

technical field [0001] The invention relates to an agricultural insecticidal composition, in particular to an acaricidal composition of tebufenpyrad and cyclopyrid. Background technique [0002] With the rapid development of my country's national economy and the continuous improvement of people's living standards, higher and higher requirements are put forward for the quantity, quality and safety of agricultural products. However, in the past ten years, due to the high quality, high yield and diversification of citrus, apple and other fruit crops, as well as climate warming and the invasion of foreign pests, the occurrence and damage of fruit tree diseases and insect pests has generally increased significantly. [0003] Acarid pests, commonly known as red spiders, are one of the main pests of fruit trees, cotton, vegetables and other crops. They not only seriously affect the growth of fruit trees and crops, but also because of the many generations of mites, they reproduce qu...
