Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of Pesticidal combination that contains penta pyrrole worm guanidine and Buprofezin.
Technical background
The kind of sap-sucking insect is a lot, comprises aphid, scale insect, leafhopper, plant hopper, wood louse, aleyrodid, the plant hopper of Homoptera, the stinkbug of Semiptera, the thrips of thrips, the mite class of Acarina etc.Its occurrence characteristic is: the nutrient with sucking mouth parts absorption tender tissue causes die back; Individual little, fertility is strong, and it is not obvious to relate to the initial stage of origination shape of often being injured, and be prone to ignored by people, but numbers of poles is many; Diffusion spreads rapidly, borrows the wind-force nursery stock to propagate a distant place; Most kinds are vector insect, and the viral disease that can spread disease and phytoplasma disease are brought the secondary disease to crop.Inhaling the juice class pest can bring harm to various crop such as cotton, paddy rice, vegetables, tealeaves, and damaging range is very wide.
Buprofezin (buprofezin), English name buprofezin, molecular formula C

23N
3OS, chemical name are 2-tertiary butyl imino group-3-isopropyl-5-phenyl-1,3,5-thiadiazine-4-ketone, and the general Buprofezin by name of Chinese, another name cloth sweet smell is clean, excellent readily takes the opportunity to, insect-catching is clean, buprofezin, Buprofezin.Buprofezin is a kind of selective insecticide that insect growth is grown that suppresses, and is main with action of contace poison, has stomach poison function concurrently.Drug effect performance is slower, and 3～5 talentes present effect after the general medication, and mechanism of action is for suppressing chitinous synthetic and disturb metabolism in the insect bodies, causes nymph cast off a skin deformity or wing deformity and slowly dead.The insecticide that coleoptera, part Homoptera and Acarina is had the lasting effect larvicidal activity.This medicine does not have direct lethality to adult, but can shorten its life-span, reduces egg laying amount, and mostly the ovum that is produced be addle-egg, even the larva of hatching is also very fast dead.There is not cross resistance with conventional pesticide.This medicine is safer to natural enemy.The drug effect lasting period reached more than 30 days.
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 is 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 structural formula of penta pyrrole worm guanidine:
