Abstract
The invention discloses a thiacloprid insecticide compound, comprising the following components: 1-50% of thiacloprid, 6-80% of chlorfenapyr, 2-12% of lignin, 1-6% of wetting agent, 2-6% of disintegrating agent, 1-5% of tea oil, 1-5% of dimethoate missible oil and the balance of carrier. The carrier is plateau soil or bentonite. The thiacloprid insecticide compound is suitable for controlling piercing-sucking mouthpart insects of paddy rice, vegetables, fruit trees, flowers and lawns. The compounding of two effective components has an obvious synergism action and improves a preventing and treating effect; the usage of a pesticide is reduced and the promotion and application of the compound have higher economic and social benefits.
Description
Technical field:
The present invention relates to the preparation method of thiacloprid disinsection compound thing, specifically a kind of preparation method containing the synergy thiacloprid disinsection compound thing of thiacloprid and capillary, for preventing and treating the suckings pest such as paddy rice, vegetables, fruit tree, flowers, lawn.
Background technology:
Thiacloprid be a kind of newly have efficient broad spectrum pesticide to sucking pest, different according to crop, insect and method of application, its consumption is 50.4 ~ 100.8ga.i./hm2.Field trial shows, thiacloprid has excellent control efficiency to the important pests on tea tree, pomaceous fruits fruit, cotton, vegetables and potato.Except to aphid, aleyrodid, thrips effectively except, it to various beetle (as colorado potato beetle, apple weevil, Lissorhoptrus oryzophilus Kuschel) and lepidoptera pest as the leaf miner on apple tree and codling moth are also effective, and all applicable to corresponding all crops.
Thiacloprid acts on nicotinic acetylcholine receptors.It and common insecticides do not have cross resistance as pyrethroid, organic phosphates and carbamates, thus can be used for resistance management.Thiacloprid has interior absorption and has Acute exposure toxicity and stomach poison function.The soil half life period of thiacloprid is short, to birds, fish and multiple beneficial arthropods safety.It is very safe to honeybee, can use equally at flowering phase of crop.Due to thiacloprid low toxicity, efficiently, liked by numerous users.
Capillary is new pyrrole class Insecticidal and acaricidal agent.To various pests, mite, there is stomach toxicity and action of contace poison, to crop safety, be applicable to control brassicaceous vegetable diamond-back moth, beet armyworm, tea tree tea lesser leafhopper, looper, mite, citrus red mites etc., have the advantages such as preventive effect is high, the lasting period is longer, dosage is low.
In recent years, the sucking pest on crops is caused harm seriously, and the medicine such as peasant's Long-Time Service Imidacloprid, Biphenthrin, chlopyrifos produces serious resistance, occurs strengthening dosage, control efficiency difference problem, and environmental pollution is also tending towards serious.
The mixture of different pesticide species is the common methods of preventing and treating agriculture resistant insect.Screened by formulation of pesticide, filter out rational formula, can effectively improve actual control efficiency, reduce dosage, reduce costs, delay the generation of pest resistance to insecticide, extending the service life of medicament, is the important means of integrated pest management.The present inventor a large amount of indoor virulences screening and field medicine effect test basis on, discovery thiacloprid and capillary mixture to suckings pest such as aphids, there is synergistic function.
Water dispersible granular can disperse rapidly in water in disintegration, being formed can for the suspension of spraying or solution, its major advantage is without dust or there is few dust to produce when producing and use, to use and producer's safety, and have the advantage of aqueous emulsion and wetting powder concurrently, thus become fashion trend formulation that is the most potential on international market and development prospect.
Summary of the invention:
The object of the invention is to overcome the shortcoming existed in prior art, there is provided using method simple, use the object of the invention is thiacloprids different for the mechanism of action and capillary are carried out mixture, make full use of the synergistic effect that both mixtures produce, there is provided a kind of agricultural chemicals thiacloprid disinsection compound thing of efficient, low toxicity, low cost, for preventing and treating the suckings pest such as paddy rice, vegetables, fruit tree, flowers, lawn.
