Abstract
The invention discloses a wilforine and pyraclostrobin seed-dressing suspension. Wilforine and pyraclostrobin are active ingredients, and the seed-dressing suspension comprises the following components in percentage by weight: 1 to 40 percent of wilforine, 1 to 40 percent of pyraclostrobin, 2 to 50 percent of a dispersing agent, 1 to 5 percent of an anti-freezing agent, 0.1 to 3 percent of a film forming agent, 1 to 10 percent of a filler, 1 to 3 percent of a mildew preventive, 0.1 to 5 percent of PH regulator, 0.5 to 5 percent of a suspending agent and 10 to 80 percent of de-ionized water. According to the wilforine and pyraclostrobin seed-dressing suspension, biochemical pesticides are adopted, so that the wilforine and pyraclostrobin seed-dressing suspension is more environment-friendly and energy-saving; an obvious synergistic effect is played after compounding, and prevention and control effects are improved; the drug resistance of pest and disease damage is retarded.
Description
technical field:
The present invention relates to a kind of crops pest, seed treatment and preparation method thereof that growth is adjusted in controlling disease, strong sprout, promotion, be specifically related to a kind of for the treatment of the wilfordine of seed and the suspension seed-coating agent of pyraclostrobin and preparation method thereof, belong to biochemical pesticide field.
background technology:
Seed coat agent is a kind of pesticides new formulation combined by agricultural chemicals, film forming agent, filler, related auxiliaries, it is a kind of process new technology of seed being carried out to dressing, the crops such as paddy rice, wheat, corn, soybean, cotton, peanut, beet, rape, melon and fruit, sunflower, Grass Seeds by Aerial Sowing have been used widely, to control soil insect if nematode, cutworm, crop pest are as aphid, thrips, leafhopper etc. and soil-borne disease Be very effective, as control rice blast and banded sclerotial blight; The powdery mildew of wheat, rust, glume blight, moire disease, Dark kernel; Grape powdery mildew; Melon and Solanaceae powdery mildew, anthracnose, spot blight, cucumber downy mildew and anthracnose are prevented; Leaf spot of peanut and rust etc., and time and labour saving, compare with other formulation and pesticide application technology that environmental pollution is little, agricultural chemicals availability is high.
Suspension seed-coating agent is a kind of flowable stable unit for uniform suspension be made up through wet pulverizing of active ingredient (insecticide, bactericide, plant growth regulator, trace element etc.), film forming agent, wetting agent, dispersant, thickener, warning colouration, filler and water.Suspension seed-coating agent, as water machine chemical preparation, has the features such as efficient, safety, environmental protection, compared with traditional seed soaking agent, seed dressing, have medication accurately, medicine film difficult drop-off, economize the advantage such as medicine, slow releasing.
Wilfordine is one of main active in thunder godvine, there is insecticidal spectrum wide, active high, the features such as toxicity is low, to lepidopterous diamond-back moth, cabbage caterpillar, suffixation of a nonsyllabic "r" snout moth's larva, the Asiatic migratory locust of orthoptera, dipterous midge, the corn weevil of coleoptera, the tetranychus viennensiss of Acarina etc. are planted insect and all have stronger food refusal and toxic action, and there is paralysis insect, suppress it to grow, suppress the specificity insecticidal actions such as population augment, wilfordine is a kind of natural insecticide, good effect is had in field, but its quick-acting and lasting effect are not given prominence to.
Pyraclostrobin (pyraclostrobin), molecular formula: C20H23N3O2, chemical name: methyl (N)-[[[1-(4-chlorobenzene) pyrazoles-3 base)-oxygen]-0-methoxyl group]-N-methoxymethyl carbamate.Pyraclostrobin is the bactericide of BASF AG's latest model methoxy acrylic.Sterling is that white is to the tasteless crystalline solid of oldlace.The mechanism of action is mitochondrial respiratory inhibitor.Make mitochondria can not produce and provide cell eubolism institute energy requirement, finally cause cell death.It can control most of diseases such as Ascomycetes, Basidiomycetes, deuteromycetes, Oomycete.There is very strong inhibitory action to the growth of spore germination and leaf intramatrical mycelium, there is protection and therapeutic activity.Have permeability and local systemic activity, the lasting period is long, resistance of rainwater washing against.Be widely used in preventing and treating the disease on wheat, paddy rice, peanut, grape, vegetables, potato, banana, lemon, coffee, fruit tree, walnut, tea tree, tobacco and ornamental plants, lawn and other field crops.This compound not only toxicity is low, to non-target organism safety, and to user and environment all safety close friends, is classified as " Candidate Agents reducing risk " by U.S. EPA.In addition, pyraclostrobin can produce positive physiological regulatory action to crop, the generation of its energy ethene suppressing, and crop can be helped like this to have longer time deposit bio-energy to guarantee maturity; The activity of the restore nitrification enzyme of crop can be significantly improved, mean the use that can reduce Nitrogen In Soils fertilizer, thus reduce underground water mitigation further; When crop is subject to viral attack, it can accelerate the formation of resisting albumen---and identical with the synthesis of crop self salicylic acid synthetic to degeneration-resistant albumen.Pyraclostrobin is the efficient mitochondrial respiratory inhibitor after improving on kresoxim-methyl basis, is the o-methyl-phenyl-that substituted for N-rubigan pyrazolyl in kresoxim-methyl molecular structure, and the another methoxy acrylic wide-spectrum bactericide of exploitation.Its activity is higher, is at present with 3 times of series bactericidal agent.
