Abstract

The invention provides a sterilization mixed preparation which has environment compatibility and is prepared from a plant source active substance mustard essential oil and allicin in the weight ratio of (1:10)-(10:1). The mixed preparation has a remarkable synergistic interaction function, can be prepared into preparations such as emulsion in water, suspension, water dispersible granules and the like, and can be used for preventing and controlling diseases such as plant powdery mildew, gray mold, phytophthora, anthracnose, wilt, downy mildew and the like, so that the prevention and control effect is improved, the dosage is reduced, the pesticide delivery time is reduced, the prevention and control range is enlarged, the requirements of the technique that the amount of pesticide is reduced are met, and moreover the preparation provided by the invention is an environment-friendly preparation, has the potential to be further developed into safe, efficient, low-toxicity and excellent sterilization agent, and is good in popularization and application prospect.

Description

technical field [0001] The invention belongs to a pesticide bactericidal composition for preventing and controlling crop powdery mildew, gray mold, phytophthora, anthracnose, fusarium wilt, downy mildew and other diseases, in particular to a bactericidal compound of mustard essential oil and allicin from plant sources and applications. Background technique [0002] Mustard, also known as mustard powder, is slightly bitter and has a strong pungent, tear-jerking taste. The main component of mustard essential oil is allyl isothiocyanate. Mustard essential oil has the characteristics of mustard, is volatile, and has a stronger pungent and spicy taste. Related studies have reported that mustard essential oil has a certain inhibitory effect on bacteria, fungi and other microorganisms. As an antimicrobial and antimold active substance, mustard essential oil is often used as a food additive in food processing and preservation; however, it has not been widely used in agriculture as ...
