The invention relates to a compound synergistic bactericidal composition for preventing and treating main diseases of tomatoes and pear trees and an application thereof. Active ingredients of the pesticide composition comprise pydiflumetofen and an active ingredient B, and the active component B comprises one of a substituted aniline bactericide and bacillus subtilis BAB-1. The pesticide composition disclosed by the invention is applied to prevention and treatment of main diseases of tomatoes and pear trees, such as gray mold, early blight, leaf mold, gray leaf spot, scab, ring spot and blackspot, and the bactericidal composition has the advantages of good fast-acting property and persistence, novel action mechanism and multiple sites, can effectively delay the occurrence and developmentof drug resistance of pathogenic bacteria, and not only has a protective effect on diseases, but also has a good treatment effect. The compound synergistic composition has the advantages that the dosage is small, and the pollution of medicaments to fruits and the environment is effectively reduced.

The invention relates to a bactericidal composition containing thifuramide and captan and its application. Contains the active ingredients Thiofuramide and Captan. The weight ratio of the active component thifuramide to captan is 1:100-100:1. The active components thifuramide and captan account for 5%-90% by weight of the composition. The invention relates to the use of a fungicidal composition comprising thifuramide and captan to prevent and control the harm of germs in cereals, fruits, vegetables and economic crops. The combination of thifuramide and captan has a synergistic effect, can treat both fungal and bacterial diseases in the soil, has multiple functions of one drug, broadens the spectrum of disease prevention, and reduces the dosage of captan, making it safer to use. Used for soil treatment or soaking (mixing) seeds, it can prevent rotten seeds and roots caused by soil diseases, ensure full seedlings, reduce seedling diseases, and the effect is better.

The invention relates to a sterilization composition containing captan and copper calcium sulfate and application of the sterilization composition. The sterilization composition contains the captan and the copper calcium sulfate which serve as active ingredients. According to the active ingredients, the weight ratio of the captan to the copper calcium sulfate is 1:100-100:1. The captan and the copper calcium sulfate which serve as the active ingredients account for 5 to 90 percent of the weight of the composition. The sterilization composition containing the captan and the copper calcium sulfate is applied to prevention and control of germ harm to grains, fruits, vegetables and economic crops. By compounding the captan and the copper calcium sulfate, a synergistic effect is achieved, and the composition can be used for treating fungal and bacterial diseases in soil, has multiple purposes and widens the disease preventing spectrum; and the consumption of the copper calcium sulfate is reduced, so that the composition is safe in use. The composition, which is used for treating the soil or soaking (mixing) seeds, can prevent seed rotting and root rotting caused by soil diseases, ensure complete seedlings and relieve diseases at a seedling stage, and has a good effect.

The invention discloses a difenoconazole and biological antifungal substance HSAF (heat stable antifungal factor) containing fungicidal composition and application thereof. The fungicidal compositiontakes difenoconazole and HSAF as main effective components, and a mass ratio of difenoconazole to HSAF is 1:25-25:1. The fungicidal composition has synergistic effects in the above ratio range, drug resistance of germs is overcome and retarded, and high fungicidal speed, great prevention effects, long efficacy lasting period and low application cost are realized. The fungicidal composition is capable of preventing and controlling various crop fungal and oomycetes diseases and evidently superior to single agents in prevention and control effects on fungal diseases such as black spot, rot, scab,anthracnose, rust disease and the like of fruit trees and vegetables.

The invention discloses a sterilizing composition comprising prochloraz and biological antibacterial substance HSAF (heat stable antifungal factor) and application of the sterilizing composition. Theprochloraz and the HSAF are main effective components of the sterilizing composition. The mass ratio of the prochloraz to the HSAF ranges from 1:10 to 10:1. The sterilizing composition has synergisticinteraction effect within the matching range, overcomes and delays drug resistance of bacteria, and has high sterilization speed, good prevention and treatment effect, long lasting period and low application cost. The sterilizing composition can be used for preventing and controlling various crop fungus and oomycete diseases, especially fungus diseases such as black spots, anthracnose, scabs andrust diseases of pear trees and apple trees, and has obviously better prevention and control effect than a single agent.
