Description
Technical field
The present invention relates to a kind of bactericidal composition, especially contain the bactericidal composition of Acibenzolar and a kind of miazines bactericide, belong to the disinfectant use in agriculture field.
Background technology
Powdery mildew is the plant disease that is caused by the Erysiphaceae in the fungi (Erysiphacesae).Powdery mildew is widely distributed in the whole world, and the dicotyledon of causing harm is particularly general.The main powdery mildew of China has the cereal class powdery mildew that is caused by standing grain powdery mildew (Ery-siphe graminis); The powdery mildew of various plants such as melon, the beans that causes by Siberian cocklebur monofilament shell (Sphaerothecafuliginea), crudefiber crop; The grape powdery mildew that causes by grape snag shell (Uncinula necator); The powdery mildew of more than 80 kind of trees such as the mulberry that causes by hazel ball pin shell (Phyllactinia corylea), pears, persimmon, walnut, chestnut, lichee, papaya papaw; Powdery mildew of the Rosa flowers that cause by rose monofilament shell (Sphaerotheca pannosa) etc.
Blade produced yellow point when powdery mildew just took place, and then enlarged to develop into circle or oval scab, and the mould layer of adularescent powdery is given birth on the surface, is conidiophore and the conidium of germ, and back scab flavescence brown is the cleistothecium of germ.Mildew is early stage disperses separately, after be unified into a big mildew, even can cover full leaf, have a strong impact on photosynthesis, eubolism is interfered, cause early ageing, output incurs loss.
In the control of powdery mildew, mainly rely on medicaments such as benzimidazole, triazole type, mancozeb.These medicaments are because long-term use has produced pesticide resistance in various degree, and control efficiency reduces.A large amount of uses of medicament have simultaneously increased residue of pesticide, and the harm food security has increased the weight of environmental pollution.
Acibenzolar: English name acibenzolar, chemical name benzo (1,2,3) thiadiazoles-7-carbothioic acid-S-methyl esters, test code number CGA245704 is called for short BTH.Molecular formula C
