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

[0029] Weigh tebufenfen (N-(4-tert-butylbenzyl)-4-chloro-3-ethyl-1-methylpyrazol-5-ylcarboxamide) and clothianidin at a weight ratio of 1:1 Oxazine (3-(2-chloro-5-thiazolylmethyl)-5-methyl-N-nitro-4H-1,3,5-tetrahydrooxadiazine-4-imine), adding twelve Sodium alkyl sulfate, calcium lignosulfonate, white carbon black, dipotassium hydrogen phosphate, soluble starch and kaolin, etc., mixed with airflow and crushed, kneaded with water, then added to a granulator for granulation, and then dried and sieved A water-dispersible granule containing tebufenfen and thiamethoxam at a weight ratio of 1:1 was obtained.

Embodiment 2

[0031] Weigh tebufenfen (N-(4-tert-butylbenzyl)-4-chloro-3-ethyl-1-methylpyrazol-5-ylcarboxamide) and clothianidin at a weight ratio of 4:1 Oxazine (3-(2-chloro-5-thiazolylmethyl)-5-methyl-N-nitro-4H-1,3,5-tetrahydrooxadiazine-4-imine), adding twelve Alkyl sodium sulfate, calcium lignosulfonate, white carbon black, dipotassium hydrogen phosphate, kaolin, etc., mixed evenly, and then pulverized in a jet mill to obtain tebufenfen and thiamethoxam with a weight ratio of 4:1 wettable powder.

Embodiment 3

[0033] Tebufenpyr (N-(4-tert-butylbenzyl)-4-chloro-3-ethyl-1-methylpyrazol-5-ylcarboxamide) and thiamethoxam (3-(2-chloro- 5-thiazolylmethyl)-5-methyl-N-nitro-4H-1,3,5-tetrahydrooxadiazine-4-imine) mixed according to the weight ratio of 80:1-1:80, The control experiment of Panonychus citrus was carried out. The experimental results are shown in Table 1.

[0034] Table 1 Control effect of tebufenpyrad and thiamethoxam acaricidal composition on citrus Panonychus

[0035]

[0036]

[0037] Theoretical toxicity index TTI = ∑ (the toxicity index TI of each single agent × the percentage of single agent in the mixture)

[0038] As can be seen from Table 1, using tebufenfen or thiamethoxam alone, the LC50 of Panonychus citrus 50 They are 21.81ppm and 53.6ppm respectively. In this example, tebufenfen and thiamethoxam are compounded according to the weight ratio range of 1:80-80:1 to obtain the acaricidal composition:

[0039] 1) The measured toxicity index (ATI) is close to o...

Abstract

The invention provides a tebufenfen acaricidal composition, comprising tebufenfen and a second active ingredient, the weight ratio of tebufenfen to the second active ingredient is 80:1-1:80, and the second active ingredient is selected from Any one or a mixture of any of neonicotinoid insecticides, macrolide insecticides and phenyl ether insect growth regulators. The tebufenpyrad acaricidal composition can enhance the activity of tebufenpyrad against harmful mites through the compounding of the second active component. Compared with the single use of the two components, in the case of reduced dosage, it can Obtain equivalent or better control effect.

Description

technical field [0001] The invention relates to an agricultural insecticide, in particular to a tebufenfen acaricidal composition. 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 quickly and grow alternately. There...
