Problems solved by technology

[0002] Fungi and bacteria are the main root causes of crop diseases, which can easily cause crop leaf and fruit drop, premature aging, and seriously affect the yield and quality of crops
At present, there are many types of fungicides used to prevent and control crop diseases, and there are also some pesticide varieties with better control effects, but fungicides are generally more targeted, and the control effects on diseases caused by different pathogens vary greatly, and it is difficult to achieve comprehensive control. purpose of the disease
The inventor has found through many years of experimental research that the bactericide allicin has a strong killing effect on some fungi and bacteria, but the duration of the effect is short, and the comprehensive control effect is not ideal when used alone, and the amount of use is large, which is harmful to Certain crops are prone to phytotoxicity

Embodiment 1

[0024] Example 1: Allicin 15%, propiconazole 10%, mineral spirits 10%, emulsifier 500#3%, phenethylphenol polyoxyethylene ether 5%, water balance.

[0025] Dissolve allicin + propiconazole in solvent oil, add surfactants in turn, stir evenly, add water, stir evenly, it becomes a milky white liquid, that is, water emulsion.

[0026] The above-mentioned finished product is diluted 1000 times with water and sprayed to control rice aspergillosis, sheath blight, rice blast and other diseases, then the disease stops infecting and the rice returns to normal growth (see application situation 1 of the embodiment).

Embodiment 2

[0027] Embodiment two: allicin 20%, difenoconazole 5%, emulsifier 500#5%, 600#10%, phenethylphenol polyoxyethylene phosphate 5%, cyclohexanone 10%, methanol 5% %, water balance.

[0028] Stir and dissolve allicin + difenoconazole in cyclohexanone, add surfactant and stabilizer methanol in turn, make up water to 100%, and continue stirring to form a homogeneous transparent liquid, that is, microemulsion.

[0029] The above-mentioned finished product is diluted 1000 times with water and sprayed to prevent and treat apple rot disease, and the apple rot disease no longer spreads, and the lesion suppression rate is 90%, while the fruit trees without spraying, the apple rot disease lesion continues to expand.

Embodiment 3

[0030] Example 3: Allicin 15%, hymexazol 15%, emulsifier 500# 5%, 603# 6%, phenethylphenol polyoxyethylene phosphate 5%, ethylene glycol 10%, water balance.

[0031] Stir and dissolve allicin + hymexazol in ethylene glycol, add various surfactants in turn, stir evenly, make up water to 100%, and after stirring well, it becomes a homogeneous transparent liquid. The preparation is a microemulsion.

[0032] The above-mentioned finished product was diluted 2000 times with water and sprayed to prevent and control ginger blast, and the disease no longer spread, and the overall control effect was more than 95%, which was obviously better than that of the control agent.

Abstract

The present invention discloses an allicin-containing prevention and treatment pesticide for crop plant diseases. The pesticide can be prepared into powder, an emulsion, a microemulsion, an aqueous emulsion or a suspension by adopting allicin and a bactericidal agent as effective active ingredients, wherein a weight percentage of the allicin is 10-70% and a weight percentage of the bactericidal agent is 1-40%. The pesticide of the present invention has the following advantages that: the pesticide is prepared by compound combination of the allicin and the bactericidal agent, such that a significant synergy effect can be generated, bacterial killing and disease prevention capacity can be enhanced, bacterial killing spectrum can be enlarged, crop yields can be improved, and especially good prevention and treatment effects for gray mold, downy mildew, leaf mold, epidemic disease, and other diseases can be provided; the pesticide of the present invention provides strong affinity for crops, can be rapidly absorbed by crops, and has characteristics of pathogenic bacteria killing, plant disease inhibiting, and no residue, in addition, drug resistance is not easily generated; the use amount of the single component in the pesticide of the present invention is reduced, such that the safety on crops is improved, and the use cost is relatively low; and allicin is adopted for plant protection so as to increase selectivity of pesticide use and prompt development of plant protection technology.

Description

Technical field: [0001] The present invention relates to a pesticide, in particular to a crop disease control pesticide containing allicin, which has a good control effect on difficult diseases such as botrytis cinerea, downy mildew, leaf mold and blight caused by fungi and bacteria. . Background technique: [0002] Fungi and bacteria are the main root causes of crop diseases, which can easily cause leaf and fruit drop, premature aging, and seriously affect the yield and quality of crops. At present, there are many types of fungicides used to prevent and control crop diseases, and there are also some pesticide varieties with better control effects, but fungicides are generally more targeted, and the control effects on diseases caused by different pathogens vary greatly, and it is difficult to achieve comprehensive control. purpose of the disease. The inventor has found through many years of experimental research that the bactericide allicin has a strong killing effect on s...
