Injecting type biological prevention and control method in solenopsis invicta nest

The invention discloses an injecting type biological prevention and control method in a solenopsis invicta nest. The injecting type biological prevention and control method is characterized by comprising the following steps: utilizing an injection device to insert a solenopsis invicta preventing and controlling agent containing pathogenic microorganisms into the solenopsis invicta nest, spraying the agent to each depth and position of the solenopsis invicta nest, and uniformly sprinkling the agent on solenopsis invicta bodies in each depth and position of the solenopsis invicta nest. Through utilizing the prevention and control method, the contact area of the pathogenic microorganisms and target insects can be increased, and solenopsis invicta nest moving phenomena caused by the damage of nest irrigation and chemical application on the ant nest are avoided; and besides, the humidity in the nest can be properly increased, and the environmental condition that the solenopsis invicta is infected with the pathogenic microorganisms is improved, so that the solenopsis invicta is more easily infected with various pathogenic microorganisms, and the insecticidal activity of the pathogenic microorganisms on the solenopsis invicta is enhanced. The injecting type biological prevention and control method has great prevention and control effects and finally achieves prevention and control purposes.

Sterilization composition containing pydiflumetofen and triazole fungicide

The invention discloses a sterilization composition containing pydiflumetofen and triazole fungicide, and application thereof to prevention and control of various fungus diseases of crops. The composition is prepared from a first active ingredient of pydiflumetofen, a second active ingredient of triazole fungicide including one kind of materials or several kinds of materials from tebuconazole, hexaconazole, difenoconazole, epoxiconazole, flusilazole, triticonazole, metconazole, ipconazole, propiconazol and prothioconazole, and various auxiliary agents; the weight ratio of the first active ingredient to the second active ingredient is 1:50 to 30:1; the ratio of the sum weight of the first ingredient and the second ingredient to the total weight of the composition is 1 percent to 90 percent. The composition can be prepared into agricultural allowable suspension, dispersible oil suspension, wettable powder, water dispersion particles, missible oil and microemulsion. The sterilization composition has the advantages that the ingredients are reasonable; the sterilization effect is good; the activity and the sterilization effect are not the simple accumulation of the activity of all ingredients. Compared with the existing single preparation, the sterilization composition has the advantages that the obvious sterilization effect is realized; the obvious synergistic effect can be achieved; the safety on the crops is high. The sterilization composition has the obvious prevention and control effects on fusarium graminearum, marssonina coronaria, cercosproa musae, rhizotonia cerealis, rhizoctonia solani and the like.
