Description
Technical Field
The invention belongs to the technical field of pesticides, and particularly relates to a pesticide composition containing difenoconazole and bacillus subtilis.
Background
Chlorofloxacin (Mefentrifluconazole) is a broad-spectrum, efficient and systemic fungicide with eradicating and protecting effects, belongs to the class of sterol demethylation inhibitors, and has the action mechanism of preventing the biosynthesis of ergosterol, inhibiting the growth of cells and finally causing the collapse of cell membranes. Different from the widely used triazole bactericide, the clobetasol bactericide contains an isopropanol structure, can reduce the mutation of pathogenic bacteria, delay the drug resistance of the pathogenic bacteria and is beneficial to delaying the generation and development of the resistance of the bactericide. Studies have shown that the cloroxen has outstanding biological activity on a plurality of intractable fungal diseases, and is suitable for a plurality of field crops and special crops such as corn, grains, soybeans, cash crops and the like worldwide. It is known that fluroxypyr is more potent than prothioconazole and epoxiconazole.
Bacillus subtilis is a mesophilic, aerobic and spore-producing rod-shaped bacterium, has various physiological characteristics and wide distribution, and is easy to separate and culture. The bacteria exist widely in nature, are non-toxic and harmless to human and livestock, do not pollute the environment, can generate various antibiotics and enzymes, and have broad-spectrum antibacterial activity and extremely strong anti-adversity capability. The bacillus subtilis not only can be widely existed in external environments such as soil, plant rhizosphere body surface and the like, but also is a common endophytic bacterium in a plant body, especially in the root and stem of the plant. At present, the strain has good disease control effect on crops such as rice, soybean, cotton, wheat, pepper, tomato, corn and the like. The bacillus subtilis successfully colonizes the rhizosphere, the body surface or the body of the plant, competes with pathogenic bacteria for nutrition around the plant, secretes antibacterial substances to inhibit the growth of the pathogenic bacteria, and induces a plant defense system to resist the invasion of the pathogenic bacteria, thereby achieving the purpose of biological control. The main control objects of the composition are plant diseases caused by filamentous fungi, such as rice sheath blight, rice blast, wheat sharp eyespot, tomato leaf mold, bean root rot, apple core rot, cotton rhizoctonia solani, cotton fusarium wilt and the like.
At present, in agricultural production, the application of pesticides is an important means for preventing and controlling plant diseases and insect pests, but with the repeated use of a large amount of existing pesticides and the improper application of pesticides by some farmers, some pests gradually begin to have relatively large resistance to the existing common pesticides, and the difficulty of pesticide control becomes greater and greater. For the problem, a common solution is to develop a new medicament and a compound medicament, but the former has high cost and long time consumption, so that the effective components of the two medicaments with different action mechanisms are combined into a compound pesticide, and the compound pesticide is an effective and shortcut way for developing and researching the pesticide and treating the problem of resistance of diseases.
Therefore, the development of a new high-efficiency, low-toxicity and safe biological source and chemical pesticide compound bactericide has important significance for preventing and treating diseases.
Accordingly, the present invention is directed to a method of making a semiconductor device.
