Description

A kind of compounded pesticides
Technical field
The invention belongs to pesticide field, relate in particular to the compounded pesticides of a kind of Avermectin and tetrachloro insect amide.
Background technology
Avermectin (Abamectin) is that a class of first being developed by the large village of university, Japanese North Zhi Denghe U.S. Merck company has desinsection, kills mite, ten hexa-atomic Macrocyclic lactone compounds of eelworm-killing activity, and in streptomycete, streptomyces griseus Streptomyces avermitilis fermentation produces.Avermectin has stomach toxicity and action of contace poison to mite class and insect, can not ovicidal.What mechanism of action was different from general insecticide is to disturb neurophysiology movable, stimulate and discharge γ-aminobutyric acid, and aminobutyric acid has inhibitory action to arthropodan nerve conduction.There is paralysis symptom after contacting with Avermectin with insect larvae in mite class adult, nymph, inertia, does not take food, dead after 2~4 days.Because not causing that insect dewaters rapidly, so Avermectin lethal effect is slower.Though Avermectin has direct action of contace poison to insect predator and insect parasite, because plant surface is residual few, therefore very little to the damage of beneficial insect, antagonism insect has good preventive effect as diamond-back moth, leaf miner, two spotted spider mite etc.Avermectin can not moved by adsorption by soil in soil, and decomposed by microorganism, thereby in environment without cumulative function, can be used as a part of integrated control.
Tetrachloro insect amide is the first bisamide insecticides with independent intellectual property right of China by the research and development of China National Chemicals Import(Sinochem) subordinate Shenyang Chemical Engineering Inst, the mechanism of action is in conjunction with the ryanodine receptor in insect bodies, suppress insect's food-taking, cause that polypide shrinks, finally cause insect dead, various lepidopterous insects are shown to excellent control efficiency.The control target of tetrachloro insect amide relates to the insects such as Noctuidae, the colorado potato beetles of rolling up Noctuidae, Pyralidae, diamond-back moth section, coleoptera and weevil and dipterous Liriomyza, the control of insect is had the lasting period long (more than 14d), without cross tolerance and on useful insect, affects the features such as very little, the mechanism of action is novel, there is vast potential for future development.
Because agricultural pests is produced and caused very large loss to crops every year, agricultural chemicals is as the Main Means of chemical control agricultural pests, and application is very extensive at present.Along with the long-term a large amount of single use of agricultural chemicals, can cause insect to produce resistance, environment is caused to larger pollution.Field trial shows, the another kind of mixed pesticide that existing medicament is different from mechanism of action can not only be postponed resistance and be produced, can also improve drug effect and residual period, reduce usage amount, reduce peasant's dispenser cost, so we are composite in order to expand insecticidal spectrum by Avermectin and tetrachloro insect amide.Two kinds of active ingredients are composite, not only can effectively prevent and treat most of insect, reduce environmental pollution, can also improve drug effect and lasting period, reduced peasant's labour cost, there is good economic benefit.
Summary of the invention
The object of this invention is to provide that a kind of insecticidal activity is efficient, lasting effect is long, the compounded pesticides of the high and low poison of quick-acting, environmental protection.Be specifically related to the composition pesticide that Avermectin and tetrachloro insect amide are active ingredient.
In above-mentioned compounded pesticides, the weight ratio of Avermectin and tetrachloro insect amide is 1:500~10:1.
Utilize above-mentioned compounded pesticides, be equipped with the known auxiliary agent of those skilled in that art, with the known method of those skilled in that art, can make formulation of the present invention.Its formulation that can process is aqueous emulsion, suspending agent, water dispersible granules.
