Embodiment 1

[0015] Prepare 100g 24% bifenazate·triazoltin (bifenazate: triazoltin is 1: 3) microemulsion, the mass ratio of each component is respectively:

[0016] Bifenazate original drug 6.20g Triazotin original drug 18.95g

[0017] Nongru 400#10g solvent oil 15g

[0018] Cyclohexane 5g Epichlorohydrin 5g

[0019] Propylene glycol 0.5g balance deionized water

[0020] The above raw materials were put into mixing according to the conventional microemulsion preparation method, and a uniform, transparent, and stable 100 g 24% bifenazate·triazolium tin microemulsion was obtained through high-speed shearing.

[0021] The triazotin in this embodiment can be replaced by any one of organotin acaricides such as fenbutatin, tricyclic tin, triphosphorus tin, triphenyltin hydroxide, etc., to form a new embodiment.

Embodiment 2

[0023] Prepare 100g 24% bifenazate·triazoltin (bifenazate: triazoltin is 1: 23) microemulsion, the mass ratio of each component is respectively:

[0024] Bifenazate original drug 1.05g Triazotin original drug 24.22g

[0025] Nongru 500#10g solvent oil 15g

[0026] Cyclohexane 5g Epichlorohydrin 5g

[0027] Propylene glycol 0.5g balance deionized water

[0028] The above raw materials were put into mixing according to the conventional microemulsion preparation method, and a uniform, transparent, and stable 100 g 24% bifenazate·triazolium tin microemulsion was obtained through high-speed shearing.

[0029] The triazotin in this embodiment can be replaced by any one of organotin acaricides such as fenbutatin, tricyclic tin, triphosphorus tin, triphenyltin hydroxide, etc., to form a new embodiment.

Embodiment 3

[0031] Prepare 100g 60% bifenazate · triazoltin (bifenazate: triazoltin is 1: 3) wettable powder, the mass ratio of each component is respectively:

[0032] Bifenazate original drug 15.47g Triazotin original drug 47.37g

[0033] Chaku powder 15g polyvinyl alcohol 8g

[0034] Balance diatomaceous earth

[0035] The above raw materials are mixed according to the conventional method of preparing wettable powder, and the mixture is put into a jet mill, and pulverized to meet the fineness requirements, and 100 g of 60% bifenazate·triazoltin wettable powder meeting the quality standard is obtained.

[0036] The triazotin in this embodiment can be replaced by any one of organotin acaricides such as fenbutatin, tricyclic tin, triphosphorus tin, triphenyltin hydroxide, etc., to form a new embodiment.

Abstract

The invention relates to an acaricidal composition containing bifenazate and organic tin miticide and an application thereof. By taking the bifenazate and the organic tin miticide as main active components and mixing with aids and excipients, the acaricidal composition is made into microemulsion, wettable powder, suspending agent, water emulsion, water dispersible granule and cream, wherein mass fraction ratio of the bifenazate to the organic tin miticide is 100:1-1:100. The acaricidal composition has great synergistic interaction, which can prevent and overcome drug resistance developed by harmful organisms and prolong service life of pesticide breed. The composition is used to control various harmful mites in economic crops, oil crops and grain crops, in particular to tetranychus cinnabarinus, tetranychus urticae koch, panonychus ulmi koch, tetranychus truncatus ehara, polyphagotarsonemus latus and aceria litchii, and the effect thereof is obviously higher than that of the two pesticides separately used.

Description

technical field [0001] The invention relates to an acaricide composition and its application, in particular to an acaricide composition with bifenazate and an organotin acaricide as main active ingredients and its application. Background technique [0002] The global agricultural planting structure is being adjusted. To achieve simultaneous development of food crops and economic crops, the development of economic crops will definitely promote the development of acaricides. At present, there are many kinds of acaricides developed in the world, and their use is very common. However, due to the short generation period of pest mites, strong fecundity, improper use methods, and frequent application times, resistance to insecticides is extremely rapid. For the prevention and treatment of various harmful mites that are becoming more and more serious, countries all over the world are constantly developing new acaricides, but they still cannot meet the needs. [0003] Bifenazate is ...
