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 citrus Panonychus mites 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

[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:

Abstract

The invention provides a tebufenpyrad mite killing composition, which comprises tebufenpyrad and a second active ingredient, wherein the mass ratio of tebufenpyrad to second active ingredient in the composition is 80: 1-1: 80, the second active ingredient is selected from any one or a mixture of any several kinds of anabasine pesticides, macrolide pesticides and phenyl ether insect growth conditioning agents. The tebufenpyrad mite killing composition can enhance activation effect of tebufenpyrad to pest mites through complex formulation of the second active ingredient, compared with individual usage of two components, under condition of reduced amount, equivalent or better prevention and treatment effect can be obtained.

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...
