Description
Technical field
The present invention relates to a kind of composition pesticide for preventing and treating crop powdery mildew, is with fluorine azoles bacterium acid amides and the phonetic phenol of second (or bupirimate) for active ingredient, for preventing and treating cucumber, grape powdery mildew.
Background technology
The resistance problem of agricultural disease is a global problem, is the emphasis problem that agricultural science and technology worker pays close attention to always.Along with the continuity year in year out of disease chemical control, the increase of Pesticide use amount and not scientifical use agricultural chemicals, germ resistance is day by day serious, and the germ kind producing resistance is on the increase.Meanwhile, the use agricultural chemicals of high strength, causes Practice for Pesticide Residue in Agricultural Products to exceed standard, environmental pollution and the increase of peasant's drug cost etc., is unfavorable for agricultural sustainable development.Therefore, the bactericide agricultural chemicals of efficient, the low toxicity of research and development, environmental protection has positive effect to agricultural sustainable development.
Fluorine azoles bacterium acid amides; English name: fluxapyroxad; it is acid amide fungicides; mainly through suppressing mitochondrial succinate acid esters dehydrase, hindering tricarbonic acid cycle, making amino acid, sugar lacks, energy reduces; the division of interference cell and growth; there is protection and therapeutic action, efficient to the gray mold of gourd, fruit and vegetable class crop, powdery mildew, also there is greater activity to fruit tree anthracnose.
The phonetic phenol of second, English name: ethirimol is miazines bactericide, mainly suppress adenosine deaminase, have extremely strong killing effect to mycelium, conidium, trichogyne etc., and the powerful formation suppressing spore of energy, block spore and infect source again, bactericidal effect is comprehensively thorough.For the crop fallen ill, the phonetic phenol of second can play therapeutic action well, can root out the germ in invaded plants body, obviously can suppress the expansion of germ, efficient to crop powdery mildews such as melon, grapes.
Bupirimate, English name: bupirimate, bupirimate is the form that the phonetic phenol of second exists with ester class, and the phonetic phenol of specific activity second is higher.
The mixture of different pesticide species is the common methods of control agricultural pest.Being screened by formulation of pesticide, filter out rational formula, can effectively improve actual control efficiency, reduce dosage, reduce costs, delay the drug-fast generation of damage by disease and insect, is the important means that agricultural synthesis is administered.The recipe determination of the present inventor to fluorine azoles bacterium acid amides and miazines conducts in-depth research, and finds that fluorine azoles bacterium acid amides and miazines carry out mixture and have obvious synergistic effect in certain mixed ratio scope to multiple fungi, after further study, completes the present invention.
Composition and the application of fluorine azoles bacterium acid amides and miazines there is no report at present.
