Thiabendazole is a kind of benzimidazole, which is a highly effective and low toxic fungicide. It disappears quickly in plants and soil. It has both therapeutic and protective effects. Spray can prevent fungal leaf diseases of many crops, such as beet, peanut leaf spot, sugarcane leaf spot and so on. Thiabendazole is more used for fruit and vegetable storage and anti-corrosion, such as apple, pear, banana, citrus, lemon and other fruit storage diseases and Potato Rot during storage. There is no ability to control the pathogens of Mucor, oospore, Phytophthora, Pythium and Rhizopus. The mechanism of thiabendazole inhibited the respiration and cell proliferation of fungal mitochondria; The effect of inhibiting bud elongation of Penicillium atruentam and other fungi is more significant than that of inhibiting spore germination, and germ tube deformity occurs at the same time. It has orthogonal mutual resistance with benzimidazole drugs such as benomyl. It belongs to benzimidazole bactericide with carbendazim, has the same bactericidal spectrum, and has high activity against the main pathogens of Ascomycetes, basidiomycetes and semiknow bacteria. It has no activity to oomycetes, Zygomycetes and plant pathogenic bacteria. The mechanism of action is the interaction between agents and fungal cells β Tubulin binding affects the formation of spindle, then affects cell division, and inhibits the respiration and cell proliferation of fungal mitochondria. The antibacterial activity was limited to Ascomycetes, basidiomycetes and semifungi, but had no activity to oomycetes and Zygomycetes.
It can effectively control plant diseases caused by Ascomycetes, basidiomycetes and semi fungi, and has protective and therapeutic effects on plants. Using it to treat harvested fruits and vegetables can effectively prevent and control diseases in storage period and prolong preservation period. It can also control the diseases of edible fungi. In addition, thiabendazole can also be used as an anti mildew agent for coatings, synthetic resins and paper products, a food additive for citrus and banana, and an insect repellent for animals.
