Abstract
A synergistic composite insecticide for preventing and treating cabbage caterpillar and rice borer contains trans-cypermethrin, abamectin or methylamino abamectin benzoate, assistant and excipient.
Description
One, technical field
The present invention relates to a kind of Pesticidal combination and uses thereof, especially a kind of is the Pesticidal combination and the application thereof of main active with theta-cypermethrin and biopesticide.
Two, technical background
Theta-cypermethrin (theta-cypermethrin), chemical name: (IR is trans) S and (IS is trans) R-alpha-cyano-(3-benzyloxy phenoxy base)-3-(2, the 2-dichloroethylene)-2,2-dimethyl cyclopropane carboxylic acid ester.
Theta-cypermethrin is a kind of widely used pyrethroid insecticides, is high-efficient broad-spectrum insecticide, and tool is tagged and the insecticide of stomach poison function, prevents and treats a lot of insects.Effective especially to coleoptera and Lepidoptera, be mainly used in the control seedling arrange, cereal.The insect of control has meadow pretty young woman at night, rice leaf roller, striped rice borer, rice leafhopper, plant hopper, stinkbug, cutworm, aphid, corn borer, cotton bollworm, pink bollworm, looper, thrips, aleyrodid, flea beetle, tomato moth, dive fly, moth-eaten moth, gypsymoth, tent caterpillar and cured coccid etc.
Theta-cypermethrin decomposes in plant corpus soon, and residual hazard is low, to the person poultry safety, belongs to the micro-virus kind agricultural chemicals, and environment is had no adverse effects.Be theta-cypermethrin missible oil but register the product that uses at present at home, do not have and other agriculture chemical compounding compositions.
The main insecticidal constituent of Avermectin (abamectin) (Avermectin B1a+B1b, wherein B1a is not less than 90%, B1b is no more than 5%) is demarcated with the content of B1a.Since the harmful utmost point in 1991 goes out after (abamectin) enter China agricultural chemicals market, the Avermectin series pesticide occupies than critical role in the control of insect system of China.
Report abamectin pest killing spectrum has 84 kinds at present, China be used for preventing and treating more polypide little, from generation to generation many, be prone to drug-fast insect such as pear sucker, cotten aphid etc., the insect of leaf mining such as Americal rice leaf miner etc., evil mite such as Tetranychus urticae, tea orange tetranychid, tetranychus viennensis and the host is wide, feeding habits are assorted insect such as diamond-back moth etc.The insecticidal mechanism of Avermectin uniqueness: Avermectin is a kind of never poison, its mechanism is the GABAA acceptor that acts on insect synapse or neuromuscular synapse, the information transmission of nerve endings in the interference insect body, promptly excite nerve not the tip emit neurotransmission inhibitor γ-An Jidingsuan (GA-BA), impel the chloride channel of GABA gate to prolong open, chloride channel had activation, a large amount of chlorions pour in and cause the hyperpolarization of neu current potential, cause neu to be in holddown, thereby block nerves is getting in touch of the tip and muscle not, makes the insect paralysis, food refusal, dead.Because of its mechanism of action uniqueness, so do not have cross resistance with the medicament of using always.
It is reported that except that the chloride channel of GABA acceptor control, Avermectin can also influence the chloride channel of other ligand controls, can induce the irreversible increase of the myofibrillar film conduction of the innerv locust of no GABA energy as Ivermectin.
Avermectin has good layer and moves activity, and layer moves activity and refers to Avermectin and can infiltrate after spraying in the crop leaf tissue, formation anther sac in the epidermis parenchyma cell, and long term storage is so avermitilis strain have the lasting period preferably.Because its good layer moves activity, make Avermectin have efficiently to the insect that evil mite, Liriomyza, leaf miner and conventional dose such as other borer pests or sucking pest are difficult to prevent and treat.Avermectin is easily degraded in soil and water, and in soil by adsorption by soil, can leaching, noresidue does not pollute the environment; It is residual also not have accumulation and persistence in vivo, so Avermectin should belong to public nuisance-free agricultural chemicals.Avermectin can also resolve into by edaphon has more highly active derivative, as the insecticidal action that produces for Plant nematode.
Emamection benaoate is the derivative of Avermectin, and its insecticidal action principle is identical with Avermectin.
The synergistic complex of agricultural chemicals is expanding prevention spectrum and the effective measures that improve preventive effect, still finds no the Pesticidal combination that closes theta-cypermethrin and biopesticide up to now.
Lepidoptera pest as cabbage caterpillar, cotton bollworm, aphid, beet armyworm, the snout moth's larva of rice etc., increases gradually in present resistance, and the agent of agricultural chemicals list descends gradually to the effect of control of insect, and agriculture chemical compounding can obviously improve drug effect, and delays the generation of pest resistance.
