Description
Technical field
The invention belongs to technical field of pesticide, relate to containing the composite ultra low volume liquids for binary active ingredient one of in Boscalid and morpholine bactericide dimethomorph, fenpropidin, butadiene morpholine, volution bacterium amine, tridemorph, be specially the ultra low volume liquids containing Boscalid and morpholine bactericide.
Background technology
At present for the control of insect agriculturally easily producing resistance, what main way was exploitation and existing kind without between the new composition of cross resistance or existing pesticide species is composite, the former is because required development cost is high, the cycle is long, and current development rate is far away less than the speed that pest resistance to insecticide produces.Therefore, the selection that mixture is a kind of the best is carried out for the existing pesticide species that the mechanism of action is different.If reasonable mixture ratio, then can produce significant synergistic effect, make field control effect significantly be better than the effect of each single dose.Certain defect is usually there is in the insecticide containing single-activity composition on agricultural insect pests control, continuous several times uses and not only makes insect easily develop immunity to drugs, and easily cause the pollution to food and environment, above shortcoming can be overcome by rational mixture between pesticide active ingredient.The reasonably composite synergistic effect that active ingredient is produced simultaneously, preventive effect can be improved, reduce effective ingredient consumption, cost-saving, delay the drug-fast generation of insect, near and the pollution even avoiding agricultural chemicals to food and environment can be alleviated, and the efficient novel pesticide of the low toxicity that the present invention researchs and develops, not only target drug effect is significantly strengthened, and very low on the impact of people, crop, non-target and environment.
Boscalid belongs to Novel tobacco acid amide fungicides; English name is Cantus; chemical name is the chloro-N-of 2-(4 '-chlorodiphenyl-2-base) vitamin PP; shifted in plant by blade face infiltration, suppress mitochondrial succinate acid esters dehydrase, hinder tricarbonic acid cycle; make amino acid, sugar lacks, energy reduces; the division of interference cell and growth, have neural activity to disease, has protection and therapeutic action.Suppress spore germination, the extension of bacterium pipe, mycelial growth and spore mother cell to form the Main Stage of conk and breeding, bactericidal action is directly caused by parent active agent, does not have corresponding metabolic activity.With carbendazim, Sukeling etc. without cross resistance.Be mainly used in preventing and treating powdery mildew, gray mold, various rot, brown rot and root rot.
