Problems solved by technology

Benthiopyram has a good inhibitory effect on the formation of oomycete sporangia and the germination of spores, but has no effect on the release of zoospores and the movement of zoospores. The results of field efficacy tests show that benthiazil can To control potato infestation resistant to benzamide fungicides and melon downy mildew resistant to methoxyacrylates, but the use of benthiazil alone is costly and has the risk of resistance
[0005] The long-term use of the above two pesticides alone will easily lead to the generation of drug resistance of pathogenic bacteria, resulting in a significant decline in drug efficacy, resulting in a significant increase in the amount of pesticides used, shortening the spraying cycle, and causing a great impact on the environment. The public's physical safety poses a great threat
It has been found that there is no relevant report on compounding benzamid and benthiazil dosage forms in the prior art

Embodiment 1

[0032] 1. Example 1: 28% Benxifluzamide·Benthiazamide wettable powder (1:1)

[0033] Benzoamide 14%

[0034] Benthiasamide 14%

[0035] Sodium dodecylbenzene sulfonate 3%

[0036] Sodium Lignosulfonate 4%

[0037] White carbon black 15%

[0038] Diatomaceous earth balance

[0039] The preparation method of the wettable powder is as follows: according to the above formula, the active ingredient of the pesticide, the dispersant, the wetting agent and the filler are uniformly mixed, stirred evenly in a stirring tank, pulverized by a jet mill and mixed uniformly, then the preparation can be obtained. The wettable powder described in the invention.

Embodiment 2

[0040] 2. Example 2: 39% benzfluzamide·benthiazamide water dispersible granules (8:5)

[0041] Benzoamide 24%

[0042] Benthiasamide 15%

Abstract

The invention discloses a pesticide composition of zoxamide and benthiavalicarb and application thereof. A weight ratio of zoxamide and benthiavalicarb which are active ingredients in the pesticide composition is 1:30-40:1, and 1:5-10:1 preferably. Weight percent content of the active ingredients in the sterilizing composition is 1-90%, and 6-70% preferably, and the balance is conventional assistant ingredients in pesticide preparation processing. The dosage forms of the pesticide composition are emulsifiable oil, wettable powder, water-dispersible granules, suspending agents, water emulsions and microemulsions. The pesticide composition is obviously better than single dosage of zoxamide and benthiavalicarb in prevention and control effect and has good application prospect and popularization value.

Description

Technical field [0001] The invention belongs to the technical field of pesticide compounding, and specifically relates to a bactericidal composition containing benzfluramide and fenthiazine and its use for preventing and curing crop fungal diseases. The bactericidal composition is particularly suitable for preventing and treating late Blight and downy mildew. Background technique [0002] Oomycetes diseases such as downy mildew and blight are common diseases in crop planting, which bring great damage to the yield and quality of crops. According to reports in the literature, due to single use of drugs and other unreasonable use of drugs, diseases such as downy mildew and blight have become resistant to multiple pesticides, resulting in a decline in the control effect of these pesticides. In order to effectively prevent and control diseases, pesticides are needed. The further increase in the use of citronella has caused environmental pollution, which is not conducive to the sustai...
