Description

A kind of Pesticidal combination that contains triaguron
Technical field
The invention belongs to technical field of pesticide, be specifically related to the composite composition of a kind of triaguron and carbamate insecticide, be used to prevent and treat aphid, rice fulgorid, aleyrodid on the crop.
Background technology
Triaguron, english common name triazamate, outward appearance is a white powder, molecular formula C 13H 22N 4O 3S, chemical name is: (3-tertiary butyl-1-dimethylamino formyl-1H-1,2,4 ,-triazole-5-base sulphur) ethyl acetate.Chemical structural formula is:
Figure G2009100211764D00011
Triaguron belongs to the high selectivity systemic insecticide, and cholinesterase is had rapid inhibitory effect, and through the suction-operated and the contact action of aphid splanchnopleure, it is all effective to the various aphids on the various crop population.Dosage with the conventional control aphid is invalid to diptera and lepidoptera pest.To useful insect and honeybee safety.
Carbaryl, English name: (carbaryl), molecular formula: C 12H 11NO 2, chemical name is a 1 naphthyl N methyl carbamate, its structural formula is:
Figure G2009100211764D00012
Carbaryl is a kind of broad spectrum pesticide, belongs to carbamates, insect is had tag, stomach poison function.Its mechanism of action is the acetylcholinesterase that suppresses in the insect bodies, and insects such as leafhopper, plant hopper are had preventive effect preferably, to some pests with chewing mouthparts that is difficult for control, like pink bollworm, aphid etc. good control efficiency is arranged also.Carbaryl is slower to the poisoning speed of insect, just begins to bring into play drug effect after the medication two days later.Different insecticidal mechanisms with other are composite to have obvious synergistic effect, and its insecticidal effect obviously is superior to independent use.
Mobucin, English name (isoprocarb), molecular formula: C 11H 15NO 2, chemical name is: methylamino formic acid-2-isopropyl phenyl ester,
Structural formula is:
Figure G2009100211764D00021
Mobucin has stronger action of contace poison, and the power of knocking down is strong, and drug effect is rapid, but the longevity of residure is shorter.Mobucin has special efficacy to rice fulgorid, Cicadellidae insect.Can doublely control thrips and leech, to plant hopper natural enemy, spider safety.
MTMC, English name: (metolcarb), molecular formula: C 9H 11NO 2, chemical name is: a tolyl-N-methyl carbamate,
Its structural formula is:
Figure G2009100211764D00022
MTMC is a kind of carbamate insecticide, has the amount of money of tagging fumigation action, and the power of knocking down is strong; But the lasting period is short; It mainly is and the acetylcholinesterase reaction after enzyme is suppressed, promptly to occur poisoning; Be mainly used in control rice fulgorid, rice leafhopper, rice thrips and stinkbug silk worm etc., rice leaf roller, oranges and tangerines blister mite, cotton pink bollworm, cotton aphid, two spotted spider mite are also had certain effect.
Aphid is claimed aphid or aphid etc. again, English aphid by name.Belong to the Homoptera Aphidiadae, fore wing 4~5 rakes, the secondary sensation circle of feeler is circular, the aphid of cornical tubulose.Contain 107 and belong to 2280 kinds.Various places all over the world distribute.Known 260 kinds of China distributes and spreads all over all parts of the country.The aphid belly has tubular protrusion (cornical), sucks water, is the major pest of plant.Aphid often troop cause harm tender leaf, tender slightly, position such as bud, suck juice, so that the irregular shrinkage of vacuum side of blade, curl, variable color, come off, bud distortion, flowers lopsided development, even complete stool is withered so that dead.Simultaneously, aphid secretes a large amount of close dew, stains branches and leaves, brings out the bituminous coal disease.The kind that has can produce insect gall, the still disseminator of plant virus who has.
The body surface of aleyrodid has wax, and breeding is fast, generation overlap, very easily develops immunity to drugs; Bring many difficulties to chemical control; Therefore the science medication is very important, when selecting for use medicament to carry out emergence control, requires mixture preparation that quick-acting is preferably arranged; Can reduce the agricultural chemicals access times, suspension of pesticide resistance generation.
The present composition can effectively be prevented and treated resistance aphid, aleyrodid, and dosage is little, quick-acting is high, and the complex preparation of triaguron and carbaryl, Mobucin or MTMC does not also appear in the newspapers so far.
Summary of the invention
