Abstract

The invention relates to the field of pesticide preparations, and discloses an insecticidal composition, which is composed of Guadipyr and imidacloprid. The invention also discloses a pesticide, which is composed of the insecticidal composition and auxiliary materials acceptable in pesticide preparation, wherein the insecticidal composition accounts for 1-85 wt% of the pesticide. The insecticidal effect of the insecticidal composition and its preparation is remarkably raised, and the preparation has an obvious synergy effect, can be used to delay the generation of insects' drug resistance, and can be widely applied in agricultural field.

Description

A kind of Pesticidal combination and preparation thereof and application

Technical field

The present invention relates to the pesticidal preparations field, relate to a kind of Pesticidal combination and preparation thereof and application specifically.

Background technology

Sucking pest; Claim " five is little " insect again; Be aphid, coccid, tetranychid, aleyrodid, thrips five class pests, they all thrust the tissue of the leaf of plant, tender stem, leaf sheath, bud, calyx, fruit, piece root, stem tuber etc. through mouthpart, draw cell juice; Destroy blade pore, spongy tissue and palisade tissue; Poisonous, the harmful substance of justacrine hinders plant normal growth and grows, thereby causes following main disease symptom: make blade chlorisis, jaundice, rubescent, shrivelled or formation insect gall; Disease bud deformity; Make blade, pericarp be rust; Make blade become the felt shape; Cause dehiscent fruit.Can make plant defoliation, fallen flowers, shedding when serious, even the large tracts of land plant is withered, causes yield and quality to descend significantly.In China, therefore the annual therefore type insect pest of crops such as paddy rice, vegetables and the loss that suffers is very serious uses the insecticide of control sucking pest significant to protection crops normal growth.

At present, the domestic insecticide that is usually used in preventing and treating sucking pest is an Imidacloprid, and chemical name is 1-(6-chloropyridine-3-pyridylmethyl)-N-Nitroimidazoline-2-base amine.Imidacloprid is a nicotinoids super-high-efficient insecticide, has characteristics such as wide spectrum, efficient, low toxicity, low-residual, to characteristics such as people, animal, plant and natural enemies securities, and have tag, multiple actions such as stomach toxicity and interior suction.Behind the insect contact medicament, the nervous centralis normal conduction is obstructed, and makes its paralysis dead.But the insecticidal effect of Imidacloprid is still not fully up to expectations.In addition, Imidacloprid makes insect have very high resistance because of for years use.

Summary of the invention

In view of this, the object of the invention provides a kind of Pesticidal combination and preparation and application, makes its control to sucking pest have synergistic effect.

For realizing the object of the invention, the present invention adopts following technical scheme:

A kind of Pesticidal combination is made up of penta pyrrole worm guanidine and Imidacloprid.

Wherein, the mass ratio of said penta pyrrole worm guanidine and Imidacloprid is preferably 1: 20-30: 1, more preferably 1: 10-10: 1, most preferably be 1: 1.

Imidacloprid, chemical name are 1-(6-chloropyridine-3-pyridylmethyl)-N-Nitroimidazoline-2-base amine, belong to the nitro-methylene-type systemic insecticide; It is the acting body of nicotinic acid acetylcholinesterase acceptor; It is malfunctioning to disturb the pest movements nervous system that chemical signal is transmitted, no cross resistance problem, have wide spectrum, efficiently, low toxicity, low-residual; To characteristics such as people, animal, plant and natural enemies securities, and have tag, stomach toxicity and the multiple drug effect of interior suction.Behind the insect contact medicament, the nervous centralis normal conduction is obstructed, and makes its paralysis dead.Quick-acting is good, higher preventive effect is promptly arranged in 1 day behind the medicine, and residual life reached about 25 days.Drug effect and temperature are proportionate, and temperature is high, good disinsection effect.Be mainly used in the control sucking pest.

Penta pyrrole worm guanidine, chemical name are 1-nitro-3-[(6-chloropyridine-3-yl) methyl]-4-penta methene amido guanidine, belong to the nitro aminoguanidine compounds that contracts; It is the brand-new insecticide of a kind of efficient, low toxicity, low-residual; Have the architectural feature of anabasine insecticide and sodium-ion channel inhibitor insecticides concurrently, thereby also have the insecticidal spectrum of this two insecticides concurrently, be with a wide range of applications; Characteristics with multiaction target, the speed that insect is developed immunity to drugs reduces greatly.This product all has the better prevention effect to multiple suckings pest such as aphid, plant hopper, cotton bollworms.

The present invention also provides a kind of insecticide, can accept auxiliary material by Pesticidal combination according to the invention and pesticidal preparations and form.

Wherein, the mass percent that said Pesticidal combination accounts for said insecticide is 1-85%, is preferably 10-70%.

According to method known in those skilled in the art, the present invention can be made into agricultural and goes up any formulation of acceptable, and the preferred formulation formulation is suspending agent, missible oil, water dispersible granules and wetting powder.Auxiliary material according to the invention can be made up of a kind of and surfactant in solid carrier, the liquid diluent, and wherein said solid carrier, liquid diluent and surfactant are at least a kind of.According to auxiliary material known in those skilled in the art, surfactant can be selected from alkylsulfonate, fatty alcohol sulfonate, APES, lauryl sodium sulfate, calcium dodecyl benzene sulfonate, lignosulfonates, carboxymethyl cellulose, agricultural newborn 500#, agricultural newborn 600#, Nongru-700 #, farming breast 2201, farming breast 8209, farming breast 8312, farming breast 8210, agricultural newborn NP-10, farming breast 0425, farming breast 0408, farming breast 3517, farming breast 8220, farming breast 8210, BX, JFC etc.; Solid carrier can be selected from bentonite, white carbon, high clay, potter's clay, diatomite, precipitated calcium carbonate, talcum powder etc.; Liquid diluent can be selected from cyclohexanone, acetone, dimethylacetylamide, methyl alcohol, methyl oleate, soybean salad oil, dimethyl sulfoxide (DMSO), water etc.

The different insecticides active component mixes each active component of back because the difference of composition, structure, physicochemical property makes that the synergy between each active component is typically expressed as synergistic effect, summation action or antagonism.So-called synergistic effect is exactly the mutual synergism between different material, and the effect of its generation is greater than the sum total of each composition effect; And being exactly the effect of its generation, summation action equals the sum total of each composition effect; Antagonism is meant that a kind of material disturbed the effect of another kind of material when two kinds of materials acted on living organism, or the effect of interfering with an opponent each other, the phenomenon that general effect is descended.

The present invention is according to Sun Yunpei (Sun Y-P) method; With resistant rice plant hopper and resistance cabbage aphid is target pest; The calculating co-toxicity coefficient estimates penta pyrrole worm guanidine and Imidacloprid is used effect with; The result shows co-toxicity coefficient all greater than 120, shows that the mixing use of the two has the notable synergistic effect, and has higher control efficiency to having drug-fast insect.

Therefore, Pesticidal combination according to the invention can be applied in the control sucking pest, and said sucking pest is preferably rice fulgorid and cabbage aphid.

Can know that by above technical scheme the insecticidal effect of Pesticidal combination according to the invention and preparation thereof significantly improves, have the notable synergistic effect, can delay the generation of pest resistance to insecticide, can be widely used in agriculture field.
