Description

A kind of complex insecticidal composition that contains triaguron

Technical field

The invention belongs to technical field of pesticide, relate to the Pesticidal combination of a kind of triaguron and Acetamiprid, Imidacloprid or Pyraphione compound, be used to prevent and treat the resistance sucking pest 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: (3-tertiary butyl-1-dimethylamino formyl-1H-1,2,4 ,-triazole-5-base sulphur) ethyl acetate.

Triaguron belongs to the high selectivity systemic insecticide, and cholinesterase is had rapid inhibitory effect, and is by the suction-operated and the contact action of aphid splanchnopleure, 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.

Acetamiprid, English name are acetamiprid, and molecular formula is C ₁₀H ₁₁ClN ₄, chemical name: E-N '-[(6-chloro-3-pyridine radicals) methyl]-N^ (2)-cyano group-N '-methylacetamide.

Acetamiprid has stronger tagging and osmosis, and the longevity of residure is long, to aphid, the aleyrodid better prevention effect of cucumber, apple tree, orange tree.Because the mechanism of action uniqueness can be prevented and treated the aphid that existing medicament is had resistance.

Imidacloprid, English name are imidacloprid, molecular formula C9H10ClN5O2, chemical name: 1-(6-chloro-3-pyridylmethyl)-N-Nitroimidazoline-2-base amine.

Imidacloprid belongs to the nitro-methylene-type systemic insecticide, and selectivity suppresses the nicotinic acid acetylcholinesterase acceptor in the insect nervous system, thereby combine the normal conduction of the nervous centralis that destroys insect with its high competitiveness, makes it death after the neural paralysis.Its mode of action is mainly stomach toxicity and tags, and has systemic activity concurrently, and the lasting period is long, and suckings pest such as aphid, leafhopper, plant hopper, aleyrodid are had good control efficiency.

Aphid claims aphid or aphid etc. again, English aphid by name.Belong to the Homoptera Aphidiadae, fore wing 4～5 rakes, the secondary sensation circle circle of feeler, 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 the 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, and brings 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, and can reduce the agricultural chemicals access times, suspension of pesticide resistance generation.

Rice hoppers is rice district, a China south important pests, and one-tenth, nymph are clustered in rice clump bottom thorn and inhale juice; When female worm lays eggs, puncture leaf sheath and blade, easily make rice strain dehydration or infect stalk break with oopod.Excreta often meets with mould and grows, and influences paddy rice photosynthesis and respiration, makes the rice strain withered, and No kernels or seeds are gathered, as in a year of scarcity when serious, becomes, nymph also can propagate viruses such as the paddy rice tooth is short.

Because the sucking pest reproduction speed is fast, selfing degree height, under the long-term prescription condition, resistance increases gradually, the agent of agricultural chemicals list descends gradually to the effect of control of insect, agriculture chemical compounding can obviously improve drug effect, and delays the generation of pest resistance, still finds no the report of the Pesticidal combination that closes triaguron and Acetamiprid, Imidacloprid or pyrrole aphid ketone up to now.

Summary of the invention

The objective of the invention is to propose a kind of Pesticidal combination that contains triaguron and Acetamiprid, Imidacloprid or Pyraphione compound, be mainly used in resistance aphid, rice fulgorid and aleyrodid on control cotton, wheat, paddy rice, the vegetables.

The present invention is achieved by the following technical solutions:

A kind of Pesticidal combination is characterized in that this Pesticidal combination comprises effective active components A and effective active composition B and auxiliary agent, excipients, and wherein effective active composition A is a triaguron, and effective active composition B can be Acetamiprid, Imidacloprid or pyrrole aphid ketone.

Described Pesticidal combination, effective active composition A is 1～80 part, effective active composition B is 1～30 part.
