Description
Technical field
The present invention relates to a kind of composition and application thereof that contains epoxiconazole and carbendazim, belong to technical field of pesticide.
Background technology
Carbendazim, English common name: carbendazim, chemical name: N-(2-benzimidazole base)-methyl carbamate is mainly used in preventing and treating cucurbits powdery mildew, epidemic disease, shallot, leek gray mold, eggplant, stem rot of cucumber, melon, bean anthracnose, powdery mildew of pea, brassicaceous vegetable gray mold, Leucoplakia etc., long-term single use carbendazim easily makes germ develop immunity to drugs, and uses by turns with other bactericide or mixes use for well.
Epoxiconazole, English name epoxiconazole, it is a kind of interior absorption triazole bactericidal agent, its active component epoxiconazole suppresses the synthetic of germ ergosterol, hinder the formation of germ cell wall, and the epoxiconazole molecule has powerful compatibility to a kind of fungal enzyme (14-dencthylase), compares with at present known bactericide, more establishment germ fungal pathogens.Epoxiconazole can improve all fourth matter enzymic activitys of crop, causes the contraction of fungi haustorium, suppresses germ and invades, and this is epoxiconazole unique characteristic in all triazole type products.The diseases such as the anthracnose on leaf spot, powdery mildew, rust and the grape on the crops such as banana, green onion garlic, celery, Kidney bean, melon, asparagus, peanut, beet, white rot there is good preventive effect.
In the real process of agricultural production, prevent and treat being easy to produce the drug-fast problem of germ in the disease process,, often occur in the melon crop growth later stage because its spread speed is fast, and host range is wide such as the powdery mildew on the agricultural, especially easily produce resistance.For example in some serious places of powdery mildew harm, common bactericide such as tpn, the spirit of methyl sulphur bacterium etc. separately use have not had any effect again, and triazolone etc. have also caused serious resistance owing to large-area application, and easily produce poisoning.Therefore the bactericide that research is not easy to develop immunity to drugs, bactericidal effect is good is determined to win.
