Abstract
The present invention relates to the application by which nimbin is in the preparation of a seed coating agent. Firstly, nimbin is used for a seed coating agent; the present invention overcomes the defect of photosensitivity and is applied in soil, the disinsection efficiency is not affected by illumination, evaporation and rainwash, and the maximal medicine quantity is protected on a target body; thereby, the stability of the nimbin is improved, effective period is prolonged, the functions of disinsection and sterilization of the nimbin is fully exerted, and the pest damage of various seeds are controlled. Simultaneously, sulfur powder is used as an active component of the seed coating agent for the first time, the characteristics of the protective sterilization and disinsection are fully exerted, and the cost of the seed coating agent is reduced; particularly, the sulfur powder and the nimbin mutually match with a high cotoxicity coefficient. The present invention solves the defects that sulfur is easy to precipitate and conglomerate, and ensures the fine stability of the nimbin.
Description
One, technical field
The present invention relates to the new application of nimbin in field of pesticides, be specifically related to the application of nimbin in kind of clothing agent.
Two, background technology
Nimbin (Azadirachtin Az) is nontoxic, the light sensitivity vegetable insecticide of generally acknowledging at present, it is a kind of highly oxidized citrin, have a lot of similar functional groups, isolated AZ-A to AZ-G7 kind activity chemistry thing from seal chinaberry seed, wherein A is main desinsection composition.Nimbin and preparation thereof have multiple effects such as food refusal inhibition, growth regulating, sterilization to insect.A kind of efficient, low toxicity, free of contamination insecticide are disclosed as Chinese patent application 99116209 " nimbin mixed pesticide preparation and preparation method thereof "; Chinese patent application 00114227 " plant-type nimbin insecticide " is disclosed also to be a kind of vegetable insecticide.Nimbin is the desirable insecticide of generally acknowledging in the world at present, but there is labile weakness under illumination, hydrolysis, the acid-base condition in nimbin.
Sulphur (Sulphur) is a kind of inorganic matter, and is water insoluble, proportion 2.07.It is protectiveness, broad-spectrum germicide, the defective that have easy conglomeration, easily precipitates.
Nimbin and sulphur are used for kind of clothing agent still to be belonged to blank both at home and abroad.And both domestic and external kind of clothing agent almost all is the agent of chemical pesticide kind clothing.
1. external: the Bltssing of the U.S. has just proposed seed coating technology as far back as the sixties in 19th century, and the purpose of dressing was to make the big granulation of seed such as cotton at that time, was convenient to sowing.
The thirties in 20th century, Britain Ger-manis seeds company has developed since the paddy class plant seed seed coating medicine first, the research and development of planting the clothing agent is rapid, English, the United States, Russia, day, in, more than 20 country such as method developed in succession and comprised plantation species clothing agent surplus soybean, corn, wheat, vegetables, paddy rice, tobacco, the flowers etc. 80, obtained significant results through application.
External seed treatment, component is single in general, and only effective at certain insect or germ, resultant effect is poor, because the sick worm plague of rats of often same time of field takes place simultaneously, the single-activity component has anti-this to lose that anxiety unavoidably.Its common feature is that agent is mixed in the agent of chemical pesticide type list or medicine fertilizer is compound, is the chemical pesticide type as Garrick show, Shi Leshi, the Wei Fu 2000 etc. that enter China abroad.
2. domestic: after the eighties, exploitation kind of the clothing agent under bureau of agriculture of the Ministry of Chemical Industry supports of China agricultural university begins, after this Chinese nation reception room or parlour, the soil and fertilizer Room, kind of a clothing agent factory is set up on Jilin, academy of agricultural sciences, Heilungkiang, Zhejiang, Jiangsu, basis, Anhui successively, carry out kind of clothing agent and develop, existing domesticly plant clothing agent factory surplus having built up 20.But the bacillus kind clothing agent (2SB) that only has the research of Zhejiang seeds company to cure the disease is biological seed coating agent, and all the other are the agent of chemical pesticide kind clothing entirely, and what have also is the agent of high seed culture of viruses clothing.
The kind clothing agent of domestic production mostly is complex composition (containing insecticide, bactericide, plant growth regulator and trace element etc.), has preventing disease pest control and seed health-care effect, and effect is comprehensive, achieves many things at one stroke.But the insect disinfestation component of present domestic kind of clothing agent is used " carbofuran " and " thimet " high-toxic pesticide more, to people and animals and operator's poor stability.
The seed coating medicine of seed pelleting (planting the clothing agent), no matter in the world more than 20 national 80 various plants coating agent for seed, or domestic more than 20 the factories kind of kind more than 30 clothing agent are the agent of chemical pesticide kind clothing.Mostly chemical pesticide kind clothing agent insecticidal activity composition wherein is to prevent and treat purpose with what high poison, high-purity agricultural chemicals reached.Therefore, the agent of existing chemical pesticide kind clothing, the pesticide resistance that often causes the pollution of environment, beneficial organism to be killed and wounded, do harm to the fungus damage worm increases, and causes the rampant again of pest.That have even in production and processing and dressing process, cause people's poisoning, cause poisoning to seed.Therefore, developing non-harmful biological seed coating agent is the task of top priority, the desire of the people.
Three, summary of the invention

5, nimbin and sulfur source
The seal chinaberry is a kind of aiphyllium, originates from Burma, and extensive growth is in India.The reservoir area of Three Gorges sends out plantation energetically long, forms the industrialization base.Extracting nimbin from it has been prior art.With the nimbin is the kind clothing agent of insect disinfestation component, fool proof to people and animals and user, good with Environmental compatibility, does not does not kill and wound pest natural enemy, is difficult to develop immunity to drugs, and belongs to the agent of environment-friendly type kind clothing.
Sulphur (Sulphur) is the abundant industrial by-products of china natural resources as the active ingredient of another biological seed coating agent, and cheap advantage is arranged.Good to preventing and treating effects such as wheat rust, powdery mildew, but also desinsection, the mite, a red-spotted lizard that kill mite, control people and animals, efficacy stability, lasting.Nontoxic to people and animals, oral 500～750 grams of people's per kilogram of body weight every day are not poisoned.
With sulphur seed dressing, the seed dressing dose is 0.3～0.4% can prevent and treat smut, and is remarkable to the black powder of wheat-straw, barley and oat covered smut and sorghum flour smut effect especially.Sulphur has volatility, attached to the Cosan of the surface of the seed, prior to seeding can with on the seed with the germ spore kill wholly or in part.Sulphur is used for kind of the component of clothing agent, does not still have report so far both at home and abroad.We are used for the broad bean seed pelleting according to the performance of sulphur, take " agent of seal sulphur kind clothing " to the wheat seed dressing, no matter single with or use planting percent with and improve 20.40%, sulphur list seed pelleting, planting percent is than CK raising 28.11%, by the mole cricket rate 6.67% that causes harm, survival rate of seedlings 56.49%.The result shows: the bactericidal active constituent that sulphur is used for the agent of nimbin kind clothing is economical, effective, feasible.
The advantage of planting the clothing agent is to set about from crops biological development starting point, and grasp the key link position and opportune time are given full play to the effect of agricultural chemicals, because multiple germ is in modes such as seed dispersal, soil propagation, and the radical bud that the invasion and attack children is tender; The seedling that various soil insects, nematode, muroid etc. also cause harm and just sprouted, crops are caused the disconnected nest of being short of seedling, therefore it is very crucial to protect kind, keep a full stand of seedings, and it seems that from pests such as sick worms they are in the revival phase after the dormancy of surviving the winter, the vitality fragility, to the drug response sensitivity, thereby eliminated easily, therefore, the agent of seal sulphur kind clothing is to best embody a kind of pesticides new formulation that puts prevention first, and can give full play to the effect of medicament.Simultaneously; seed is close in the agent of seal sulphur kind clothing; form the protection barrier; make all borders of seed pest be difficult to survive; and the seed pelleting medicine is concentrated, and the availability height is a kind of province medicine, saving of labor, save time, economize the science administrated method of planting; plant the seed that the clothing agent coats; medicine slowly discharges, and does not extensively contact the temperatures involved of not exposed to the sun and rain again with soil in addition; thereby the lasting period prolongs relatively; seed pelleting is to carry out among a small circle, and is to be sowed in the soil, to atmospheric environment, soil is pollution-free, do not injure natural enemy; help integrated control, preserve the ecological environment.
