Description
Technical field
The invention belongs to the plant protection technology field, relate generally to a kind of desinsection, sterilization corn seed coating agent.
Background technology
Planting the clothing agent is a kind of material that is used for the crop seed dressing, has film forming characteristics; usually be processed into by active ingredient (insecticide, bactericide etc.), film forming agent, dispersant, antifreezing agent and other auxiliary agents; can directly or after dilution be coated on the surface of the seed, form the pesticidal preparations of protection tunic with certain intensity and permeability.Kind of clothing agent treatment technology has efficacy of a drug lasting period length, a medicine multiple-effect, water conservation drought resisting, promote growth, improve quality, improve advantages such as percentage of seedgermination, be one diseases prevention, control the seed processing technology that worm, sterilization, promotion grow and combine together.
The used farm chemical ingredients of clothing agent dressing is planted always based on old pesticide species by China, and prior art mainly contains following several for the report of corn seed coating agent:
(1) Chinese patent application CN200810140586.6 discloses a kind of chlopyrifos and Tebuconazole and corn seed coating agent of containing;
(2) Chinese patent application CN200310114636.0 discloses a kind of corn seed coating agent that contains Imidacloprid and Tebuconazole;
(3) Chinese patent application CN200910064094.8 discloses the corn seed coating agent of a kind of Le Siben of containing and alkene azoles alcohol;
(4) Chinese patent application CN200510028697.4 discloses a kind of corn seed coating agent that contains carbofuran and alkene azoles alcohol;
(5) Chinese patent ZL00135477.9 discloses a kind of corn seed coating agent that contains carbamate insecticide and triazole bactericidal agent.
In the above-mentioned composite type corn seed coating agent, chlopyrifos and Le Siben are organophosphorus insecticides, and Imidacloprid is a nicotinic insecticide, and carbofuran is a carbamate insecticide, these insecticides mostly are the insecticide of old kind or high poison, and for example the U.S. has announced the carbofuran forbidden.
So be badly in need of a kind of high-efficiency low-toxicity of exploitation, environment amenable corn seed coating agent.
Fluorine worm nitrile has another name called sharp strength spy, trade name Regent, former is the Phenylpyrazole insecticides of French Luo Na-Planck exploitation in 1981, insecticidal spectrum is wide, based on stomach poison function, have concurrently and tag and certain systemic action, important pests such as aphid, leafhopper, plant hopper, lepidopterous larvae, fly class and coleoptera are had very high insecticidal activity, crop is not had poisoning.Control has produced the insect of resistance for organic phosphates such as acephatemet, pyrethroid, carbamate chemicals for agriculture, and good control efficiency is arranged.There is not mutual pesticide resistance with current insecticide commonly used.This medicament imposes on effectively soil insect such as chrysomelid, the wireworm of control of grubs, root and cutworm of soil.Though caused its scope of application because fluorine worm nitrile has excessive risk to shell-fish aquatile and honeybee, nitrile is used for coating agent for seed but the regulation of medicine inspecting institute of the Ministry of Agriculture allows the fluorine worm, that is: " from October 1st, 2009, the pesticidal preparations product of fluorine-containing worm nitrile composition only can be applied for the field trial of health usefulness, part dry land coating agent for seed, registration temporarily and formal registration ".As seen, fluorine worm nitrile is used for substituting original carbofuran, thimet, the red contour malicious agricultural chemicals of furans, as the main component of dry land coating agent for seed, has good DEVELOPMENT PROSPECT and important and practical meanings and necessity.
Triazole bactericidal agent (triazole fungicides) is the sterol biosynthesis inhibitor, destroys somatic cells film function.Be that representative enter agricultural chemicals market with triazolone (triadimefon) seventies in 20th century, showed the triazole bactericidal agent development prospect with its remarkable drug effect, uses for many years to show that the bacterium that do not find the cause of disease as yet produces resistance to it.Triadimenol (triadimenol), Tebuconazole (Tebuconazole), own azoles alcohol (hexaconazole), alkene azoles alcohol a series of kinds such as (diniconazole) have in succession been developed thereafter.Triazole bactericidal agent also has the physiological usefulness of adjusting to plant except that the tool bacteriostasis, can not only have the superelevation bactericidal activity rapidly by plant absorbing and mainly to the top transfer as Tebuconazole, also can promote plant growth, improves output.Can effectively prevent and treat the multiple diseases of cereal crop.As maize head smut, corn gall smut, corn banded sclerotial blight, corn base rot disease, loose smut of wheat, wheat sharp eyespot, take-all etc.
With fluorine worm nitrile and triazole bactericidal agent is desinsection, the sterilization corn seed coating agent of active ingredient, has high-efficiency low-toxicity, the double characteristics of controlling of environmentally friendly and sick worm, meets kind of the demand for development of clothing agent and a direction.
Summary of the invention
The objective of the invention is at corn field damage by disease and insect occurrence characteristic,, provide a kind of high-efficiency low-toxicity, the double corn seed coating agent of controlling of environmentally friendly, sick worm in conjunction with the existing kind of deficiency that the clothing agent exists and the developing direction of related agents.
For reaching goal of the invention the technical solution used in the present invention be: adopt soil insects such as, cutworm chrysomelid, grub to corn field wireworm, root efficiently insecticide fluorine worm nitrile and to diseases such as maize head smut, gall smut, base rot disease, rough dwarf disease efficiently triazole bactericidal agent be main component, they are pressed suitable proportion mixes, add other auxiliary element simultaneously, be prepared into high-efficiency low-toxicity, the double corn suspension seed coating of controlling of environmentally friendly, sick worm.
