Problems solved by technology

[0004] In the prior art, the use of a single agent of boscalid and dimethomorph requires a sufficient dose to achieve a control effect, and a large amount of use will have a relatively high risk of drug resistance, resulting in an increase in the cost of use
There is no report on the compounding of boscalid and dimethomorph

Embodiment 1

[0021] 24% Boscalid Dimethomorph Water Dispersible Granules

[0022] The raw material ratio is: boscalid 6%, dimethomorph 18%, sodium lauryl sulfate (surfactant) 2%, white carbon black (filler) 4%, sodium lignosulfonate ( Dispersant) 5%, bentonite (filler) to make up to 100%. Dry pulverize the above formula according to the proportion, granulate, dry and sieve to obtain 24% boscalid·dimethomorph water-dispersible granules.

[0023] The formula is diluted and sprayed 1500 times for the prevention and control of cucumber downy mildew, and the control effect is 92.1% 7 days after application. 50% boscalid water-dispersible granules were diluted and sprayed by 1000 times, and the control effect was 81.2% after 7 days of application, and 40% dimethomorph water-dispersible granules were diluted and sprayed by 1000 times, and the control effect was 69.7% after 7 days of application. %. The test showed that: 24% boscalid · dimethomorph water dispersible granules had a good control ...

Embodiment 2

[0025] 42% Boscalid Dimethomorph Water Dispersible Granules

[0026] The raw material ratio is: boscalid 6%, dimethomorph 36%, sodium lauryl sulfate (surfactant) 2%, sodium carboxymethyl starch (filler) 2%, lignosulfonic acid Sodium (dispersant) 5%, bentonite (filler) make up to 100%. The above formula is superfinely pulverized, granulated, dried and sieved according to the proportion to prepare 42% boscalid·dimethomorph water-dispersible granules.

[0027] The formula is used to prevent and control tomato late blight by 2000 times dilution and spraying, and the control effect is 93.7% 7 days after application. 70% boscalid water-dispersible granules were diluted and sprayed by 1000 times, and the control effect was 83.2% 7 days after application, and 40% dimethomorph water-dispersible granules were sprayed by 1000 times, and the control effect was 69.7% after 7 days. %. The test showed that: 42% boscalid · dimethomorph water dispersible granule had a good control effect on...

Embodiment 3

[0029] 18% Boscalid Dimethomorph Suspension Concentrate

[0030] The raw material ratio is: boscalid 6%, dimethomorph 12%, sodium lignosulfonate (dispersant) 5%, ethylene glycol 5% (antifreeze), white carbon black 2% (filler ), sodium alginate 1% (suspending agent), and deionized water to make up to 100%. The above formula is pre-crushed according to the proportion, and then added to a sand mill for grinding, and then prepared after high-shear mixing to prepare a 32% boscalid dimethomorph suspension concentrate.

[0031] The formula for preventing and controlling cucumber gray mold is diluted and sprayed by 1500 times, and the control effect is 91.7% after 7 days of application. 20% boscalid suspension was diluted 1000 times and sprayed, the control effect was 80.7% 7 days after application, and 20% dimethomorph water dispersible granule was diluted 1000 times and sprayed, the control effect was 68.9% 7 days after application. The test showed that: 18% boscalid · dimethomorp...

Abstract

The invention discloses a sterilizing composition containing boscalid and dimethomorph. Boscalid and dimethomorph are active components, and the weight ratio of boscalid to dimethomorph is 1:10-6:1. Due to the fact that boscalid and dimethomorph which respectively possess different action mechanisms are compounded, the sterilizing composition has obvious synergy effect; the composition has relatively wide sterilization spectrum, and is used to control common diseases such as downy mildew, late blight, botrytis and the like during crop plantation; the composition helps to reduce pesticide application amount, so that the cost and the pollution to environment are reduced; and the composition is beneficial for resistance treatment on diseases, and the popularization and the application of the composition have relatively large economical benefit and social benefit.

Description

technical field [0001] The invention relates to a bactericidal composition, in particular to a bactericidal composition containing boscalid and dimethomorph. Background technique [0002] Boscalid, English name: Boscalid, chemical name: 2-chloro-N-(4'-chlorodiphenyl-2-yl)nicotinamide. Boscalid is a new type of nicotinamide fungicide with a wide bactericidal spectrum and is active against almost all types of fungal diseases. It is very effective in preventing and controlling powdery mildew, gray mold, sclerotinia and various rot diseases, etc. It is also effective for resistant bacteria to other chemicals, and is mainly used for the prevention and control of diseases including rapeseed, grapes, fruit trees, vegetables and field crops. No cross-resistance with carbendazim, saccharin, etc. [0003] Dimethomorph, English common name: dimethomorph, chemical name: (E,Z)-4-[3-(4-chlorophenyl)3-(3,4-dimethoxyphenyl)acryloyl]? phylloline. Dimethomorph is a specific agent for the ...
