Problems solved by technology

The above-mentioned highly toxic pesticides currently still occupy nearly 1 / 3 of the domestic pesticide market share, and their limited production will give up a huge market space for a batch of high-efficiency, low-toxicity, and low-residue new pesticides

Embodiment 1

[0026] Embodiment 1: control red spider

[0027] According to the weight ratio of bifenthrin (unless otherwise specified, the average weight percentage) 10%, chlorfenapyr 30%, dispersant sodium lignosulfonate 15%, disintegrant aluminum chloride 3.5%, stabilizer triphosphate 1.5% butyl ester, 5% wetting agent pull-off powder, and 35% bentonite carrier to make water-dispersible granules. The formula is diluted and sprayed by 2000-2500 times, and the control effect in the field is 98.61% within 72 hours after spraying. 10% bifenthrin water dispersible granules and 30% chlorfenapyr, water dispersible granules were used in the same way, and the control effects were 78.16% and 13.1% respectively after 72 hours of application

Embodiment 2

[0028] Embodiment 2: control red spider

[0029] According to the weight ratio of bifenthrin (unless otherwise specified, the average weight percentage) 10%, chlorfenapyr 30%, dispersant sodium lignosulfonate 15%, disintegrant 4%, stabilizer BHT 1.5%, Thickener gum arabic 5%, antifreeze urea 0.5%, wetting agent pull apart powder 5%, water supplemented to 100%. Made into a composition suspension. The formula is diluted and sprayed by 2000-2500 times, and the field control effect is 90.98% within 72 hours after application. 10% bifenthrin suspension concentrate and 30% chlorfenapyr were used in the same way, and the control effects after 72 hours were 80.52% and 13.31% respectively

Embodiment 3

[0030] Embodiment 3: control spider mite

[0031] According to the weight ratio of bifenthrin (unless otherwise specified, the average weight percentage) 10%, chlorfenapyr 30%, dispersant sodium lignosulfonate 17%, stabilizer tributyl phosphate 3%, wetting agent pull apart Powder 5%, carrier bentonite 35%, made into wettable powder. The formula is diluted and sprayed by 2000-2500 times, and the field control effect is 91.68% within 72 hours after spraying. 10% bifenthrin wettable powder and 30% chlorfenapyr were used in the same way, and the control effects were 76.38% and 12.8% respectively after 72 hours of application

[0032] From Examples 1, 2, and 3, it can be concluded that the compounding of the same component bifenthrin and chlorfenapyr has more than 2 times the control effect on spider mites than that of a single agent of bifenthrin or chlorfenapyr.

Abstract

The invention discloses an Acaricide compound that can prevent a plurality of pests like red spider, etc., in citrus trees and is provided with an effective component of bifenthrin, and the application for the bifenthrin. Component A is bifenthrin, while component B comprises any one of azocyclotin or chlorfenapyr. The weight percentage between A and B in the compound is 1 to 20 : 80 to 1, with the rest being excipient. The advantage lies in that the available component combines with the effect lasting component, which results in obvious synergism action and is characterized by high effect, low pollution, low residue and hard to produce resistance even with long period usage, etc., while being used for controlling the common evil acarines in fruit trees like red spider, white spider, cotton spider, rust spider, tea leafhopper etc., commonly occurring in fruit trees, cotton and tea. From the embodiments 4, 5 and 6, results can be reached that: the control effect on red spiders of the azocyclotin and chlorfenapyr re-preparation is two times higher than that of a single agent of azocyclotin or chlorfenapyr.

Description

Technical field: [0001] The invention relates to a pesticide acaricide composition, in particular to an acaricide composition containing an active ingredient of bifenthrin, which can prevent and control various pests such as citrus red spider mites and has a killing effect, and an application thereof. technical background: [0002] At present, countries all over the world have become more and more aware of the necessity of upgrading the structure of pesticide products, and at the same time are fully promoting the development of new pesticides with high efficiency, safety and good environmental compatibility. The United Nations Environment Program and the World Food and Agriculture Organization joined forces with more than 150 national and local representatives in the world to formulate the PIC Convention (abbreviation for "Prior Informed Consent Procedures for Certain Hazardous Chemicals and Pesticides in International Trade"). The import and export of more than 20 kinds of ...
