Problems solved by technology

Etoxazole has been used for many years, and some harmful mites have developed resistance to it. Because of its poor quick-acting effect and ineffectiveness against adult mites, its damage cannot be controlled during the peak blooming period of mites

Embodiment 1

[0036] Weigh 25% pyrimethan, 5% etoxazole, 3% TERSPERSE4894 (produced by Huntsman, USA), 1% TERSPERSE2500 (produced by Huntsman, USA), 0.3% xanthan gum, 5% propylene glycol, 0.5% Benzoic acid, 0.5% silicone defoamer (trade name: s-29, produced by Nanjing Sixin Applied Chemicals Company), and deionized water were added to 100% by weight. The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 30% pyrimethan-etoxazole suspension concentrate.

Embodiment 2

[0038]Weigh 20% pyrimethan, 10% etoxazole, 4% TERSPERSE4894 (produced by Huntsman, USA), 2% TERSPERSE2500 (produced by Huntsman, USA), 2% TERSPERSE2020 (produced by Huntsman, USA), 0.2% magnesium aluminum silicate, 5% ethylene glycol, 0.5% formaldehyde, 0.5% silicone defoamer (trade name: s-29 produced by Nanjing Sixin Applied Chemicals Company), deionized water to 100% by weight . The above raw materials were mixed, dispersed at high speed for 30 minutes, and sanded with a sand mill to prepare a 30% pyrimethan-etoxazole suspension concentrate.

Embodiment 3

[0040] Weigh 8% pyrimethan, 16% etoxazole, 3% GY-D06, 3% alkylnaphthalene sulfonate formaldehyde condensate (diffusion agent NNO), 1.5% sodium lauryl sulfate, 5% white carbon Black, 3% sodium polyphosphate, and kaolin add up to 100% by weight. The above raw materials are mixed, pulverized by ultra-fine airflow, and mixed to prepare 24% pyrimethan-etoxazole wettable powder.

Abstract

The invention discloses an acaricidal composition containing pyriminostrobin and etoxazole and a use thereof. Active components of the acaricidal composition comprise pyriminostrobin as a first active component and etoxazole as a second active component. A weight ratio of the first active component to the second active component is in a range of 1:7 to 10: 1. The acaricidal composition can be processed into an agriculture acceptable suspending agent, wettable powder, water dispersible granules or a dispersible oil suspending agent. The acaricidal composition has a reasonable formula and good acaricidal effects. The activity and the acaricidal effects of the acaricidal composition are superior to simply superposed activity and acaricidal effects of all the components. Compared with single-component preparations, the acaricidal composition has obvious acaricidal effects, produces obvious synergism, has good crop safety and satisfies pesticide preparation safety requirements. The acaricidal composition has obvious effects of preventing and controlling citrus red mites, European red mites and cotton leaf mites.

Description

Technical field [0001] The present invention involves a mite killing composition, consisting of the first active ingredients of mimicamine and athidazole of the second active ingredients, which belongs to the field of complex pesticide technology. Background technique [0002] The mites in agricultural production are also called red spiders, yellow spiders, etc., which are spider -shaped mites.Mainly harms citrus, apples, cotton, vegetables, wheat and other crops. Mittimonians are more gathering on the back of the blades, and adults and nymphs are pierced into the leaves to suck juice.When mites of mites occur, the prevention and control of mite killing agents is the most effective means. At present, the drugs registered in the Ministry of Agriculture to prevent agricultural mites mainly include Avin, Dar mites, pyrodite, phenyl tin, etc.It has been resistant to it, which leads to poor speed and effectiveness of prevention and control. It is urgent to invent a pesticide that can ...
