Abstract
The invention relates to a pesticide composition with a synergistic effect and a complementary action. The pesticide composition comprises effective components of: thiacloprid and validamycin according to a weight ratio of (1-50):(50-1); and the effective active components are added with an assistant and a filler so as to prepare wettable powder, an aqueous dispersion granule and a suspending agent. The pesticide composition can be used for delaying the resistance to drugs of pests and insections, and can be widely applied to the field of agriculture.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of composition pesticide that contains penta pyrrole worm guanidine and jinggangmeisu.
Technical background
Rice fulgorid is one of several kinds of primary pests of hazard rice, and it removes directly thorn suction juice to the harm of paddy rice; Make growth retardation, the rice clump is agglomerating withered when serious, even outside the dead stalk lodging in full field; Lay eggs and also can stab plant, destroy conducting tissue, hinder the nutriment transportation and the viral disease that spreads disease.Rice sheath blight disease is that one of the most general main disease takes place paddy rice, and national paddy fields all has generation, generally contains at tillering stage to heading stage and sends out.Banded sclerotial blight and rice fulgorid are in close relations, and it is many that quantity takes place general rice fulgorid, and banded sclerotial blight will be serious relatively.Because behind the rice fulgorid hazard rice, cause a large amount of wounds at the stem stalk, be convenient to the intrusion of sheath blight fungus, and the honeydew of its discharge can promote growth, intrusion and the harm of sheath blight fungus.Therefore, both will prevent and treat synchronously.Exploitation to rice fulgorid and the double Recompounded pesticide of controlling of banded sclerotial blight ability is very important.
Penta pyrrole worm guanidine structure:
Summary of the invention
In view of this, the objective of the invention is to propose a kind of composition pesticide, make it can prevent and treat rice fulgorid and rice sheath blight disease simultaneously, and prevent the generation or the delaying drug resistance speed of pest resistance to insecticide, use cost is low, preventive effect good.
The present invention realizes through following technical scheme:
A kind of composition pesticide is made up of penta pyrrole worm guanidine and jinggangmeisu.
Wherein, said composition pesticide, the mass ratio of penta pyrrole worm guanidine and jinggangmeisu is preferably 1～60: 70～1, more preferably 1～40: 50～1, most preferably be 5～35: 30～5.
Jinggangmeisu is the antibiotic that a kind of actinomycetes produce, English name Validamycin, chemical name [N-(1S)-(1,4; 6/5)-and 3-methylol-4,5,6-three hydroxyls hexamethylene-2-thiazolinyl] [0-β-D-glycopyranosyl-(1 → 3)-(1S)-(1,2; 4/3,5)-2,3; 4-trihydroxy-5-methylol cyclohexyl] amine, another name valida, molecular formula C

13N.Have stronger interior absorption, the easy absorption also by somatic cells conducted rapidly within it, disturbs and inhibition somatic cells g and D.Be mainly used in rice sheath blight disease, the control of corn northern and southern leaf blight and vegetables and crop pests such as cotton, beans.Large-scale for many years field uses the result fully to show the characteristics of the environmental protection type agricultural chemical of its " preventive effect height, no poisoning, pollution-free ".
Penta pyrrole worm guanidine is first nitro of our seminar of China Agricultural University initiative aminoguanidine insecticides that contracts; Agriculture chemical registration is checked and approved " penta pyrrole worm guanidine " by name; English name " Guadipyr "; Chemical name 1-nitro-3-(6 '-chloro-3 '-picolyl)-4-valeraldehyde aminoguanidine that contracts, female, great and mighty or powerful mouse acute oral LD
50＞5000mg/kg.BW belongs to little poison, is non-stimulated level to lagophthalmos, skin irritatin intensity; Abnormal (sensitization) intensity of skin is the I level; Belong to weak sensitizer, the Salmonella reversion test result is negative, rat acute toxicity is had only about 1/10 (Imidacloprid is 450mg/kg.BW) of Imidacloprid.Imidacloprid belongs to high poison level, and penta pyrrole worm guanidine is a low toxicity level, and the absorption toxicity to honeybee is lower 10 times than Imidacloprid in addition.The result shows, penta pyrrole worm guanidine has efficiently, low toxicity and the good characteristic of safety.Have the architectural feature of anabasine insecticide and sodium-ion channel inhibitor insecticides concurrently; Has desinsection pedigree widely; Characteristics with multiaction target, this product all has the better prevention effect to multiple suckings pest such as aphid, plant hopper, cotton bollworms.
The Pesticidal combination of described penta pyrrole worm guanidine and jinggangmeisu, penta pyrrole worm guanidine is different with the mechanism of action of jinggangmeisu, and both are composite, have certain complementation and synergistic effect.
The composition pesticide of described penta pyrrole worm guanidine and jinggangmeisu adds corresponding adjuvants and filler according to method known in those skilled in the art, can process wetting powder, water dispersible granules, suspending agent.
