Abstract
A composite insecticide for preventing and eliminating the pests (yellow rice borer, striped rice borer, leaf rolling rice borer, plutella xylosteela, noctuid, etc) with high effect and low pollution contains proportionally abamectin, chlorfluazuron, assistant and solvent or filler.
Description
Technical field:
The invention belongs to the agricultural chemicals of control pest, relate to the composite insecticide that a kind of effective active composition is Avermectin and fluorine pyridine urea.
Background technology:
Along with the fast development of Chinese national economy and improving constantly of living standards of the people, more and more higher requirement has been proposed for quantity, quality and the safety thereof of agricultural product.But, over past ten years, because high-quality, high yield and the variation of crops such as paddy rice, vegetables, and climate warming and the invasion of external pest, causing harm of diseases and pests of agronomic crop totally is the situation that rises significantly.Primary pests such as rice leaf roller, rice borer, vegetables beet armyworm, prodenia litura, diamond-back moth, cabbage caterpillar frequently break out.Wherein, rice leaf folder, the big generation of rice borer 1999-2005 are to breaking out.Only prevent and treat 1 of rice borer, per season paddy rice use chemical pesticide 5-7 time.Economic crops such as vegetables are then various owing to the kind layout, crops for rotation are complicated, the frequent and chemical pesticide usage amount increase of the generation of diamond-back moth, beet armyworm, prodenia litura insect, and residue of pesticide exceed standard surprising.The vegetables of a large amount of outlets of China are returned goods by states such as Japan, European Union repeatly owing to organic phosphor, residual the exceeding standard of chrysanthemum ester class chemical pesticide, export volume is had a strong impact on.Chemical pesticide has not only caused serious farmland ecological environment and water pollution, and has directly increased the residual quantity of agricultural product toxic chemical substances, and human health is caused serious threat.The fundamental way that solves this outstanding problem is: break through at present the limitation based on the Preventing Countermeasures of chemical pesticide, developing is insect control technology system core, highly effective and safe with biopesticide and bionic pesticide, for the production of nuisanceless high quality agricultural products provides the core safeguards technique, become a kind of global development trend.
Avermectin, English common name abamectin; Chemical molecular formula (1) (C

14), other title: Agrimec, Abamectine likes power mite gram, likes to go out than rhzomorph, avermectin, mite light light, Olivomitecidin, the evil utmost point.Insect and evil mite are had and tag and stomach poison function, and very faint fumigation action is arranged, no systemic action has very strong osmosis to blade, can kill the insect below the table.Its mechanism of action is the neurophysiology activity of interference insect, stimulates to discharge γ-An Jidingsuan, suppresses the nerve conduction of insect.Make insect, evil mite paralysis symptom occur, inertia is got food and death.Residual few at plant surface, in environment, there is not accumulation.Avermectin can be prevented and treated Lepidoptera, Diptera pest and the evil mite on the multiple kinds of crops.
Fluorine pyridine urea, English common name chlofluazuron; Chemical name is 1-[3,5-two chloro-4-(3-chloro-5-trifluoromethyl-2-pyridine oxygen base) phenyl]-3-(2, the 6-difluoro benzoyl) urea, other title: press down hooligan, UC 62644.Mechanism of action mainly is to suppress chitin to synthesize, and hinders insect and normally casts off a skin, and makes the developmental deformity of hatching, larval molting and the pupa of ovum, and adult eclosion is obstructed and brings into play insecticidal action.But only effective to the prematurity insect, act on slower.Multiple lepidoptera pest and orthoptera, Hymenoptera, Diptera pest are had very high activity, and the insect that insecticides such as organic phosphor, carbamate, pyrethroid has been produced resistance has good control efficiency.
Summary of the invention:
The objective of the invention is to: at using Avermectin and fluorine pyridine urea pest control at present separately, dosage is bigger, and cost is higher, reuses the practical problem that insect easily produces resistance, and a kind of composite Avermectin fluorine pyridine urea insecticide is provided.Because Avermectin is different fully to the mechanism of action of target pest with fluorine pyridine urea, both composite uses can fully improve the performance of drug effect, improve insecticidal effect, reduce dosage, reduce cost, and delay the generation of pest resistance.
The object of the present invention is achieved like this: a kind of Avermectin fluorine pyridine urea compounded pesticides, comprise effective active component, auxiliary agent and solvent or inserts, it is characterized in that: the effective active composition is Avermectin and fluorine pyridine urea, and the weight proportion of Avermectin and fluorine pyridine urea is 1: 1～99; Or 2～10: 1.
In the compounded pesticides that the present invention relates to, the shared percentage by weight of each effective active composition, auxiliary agent and solvent or inserts is: Avermectin 0.1-20%; Fluorine pyridine urea 1-20%; Auxiliary agent 5～30%; Solvent or filling auxiliary material 30～75%.
The formulation that compounded pesticides of the present invention relates to comprises missible oil, aqueous suspension agent, wetting powder.
The invention has the advantages that: after Avermectin and fluorine pyridine urea are composite, have notable synergistic and lasting control efficiency; Enlarged insecticidal spectrum, lepidoptera pests such as paddy rice paddy stem borer, striped rice borer, leaf-roller, brassicaceous vegetable diamond-back moth, cabbage caterpillar, beet armyworm, prodenia litura have been had greater activity; Reduce the dosage of agricultural chemicals, reduced the residual quantity of agricultural chemicals on crop, alleviated environmental pollution; , insect good to person poultry safety, Environmental compatibility is difficult for developing immunity to drugs.
