Abstract
The present invention belongs to the field of farm pesticide technology, and is especially one kind of re-compounded pesticide comprising emamectin benzoate in 0.1-10 wt% and fipronil in 0.2-10 wt%. The re-compounded pesticide may be prepared into oil emulsion, aqueous emulsion, wettable powder, soluble liquid, microemulsion and other forms. It has cotoxicity coefficient 106-146, broad pesticidal spectrum, quick acting, high speficity and relatively low cost. It is suitable for preventing and killing pests of rice, cotton, vegetable, fruit tree, etc, and has excellent preventing and killing effect, especially on rice leaf roller, and no untoward reaction on rice growth and development.
Description
Affiliated technical field
The present invention relates to Recompounded pesticide, particularly a kind of Recompounded pesticide that rice leaf folder is had certain effect.Be specially emamectin-benzoate and Firponil compounded pesticide.
Background technology
Emamectin-benzoate (emamectin benzoate) is to be raw material with the Avermectin, and a kind of new and effective, the wide spectrum, the longevity of residure long antibiotics insecticidal/acaricidal agent that obtain semi-synthetic through chemistry, its mechanism of action hinders pest movements nerve information transmission and makes the health paralysis dead, the mode of action is main action of contace poison with stomach toxicity, institute effectively infiltrates and uses crop epidermal tissue, thereby have the longer longevity of residure, and insect is difficult for producing resistance.Sucking mouth parts and pests with chewing mouthparts there is fine preventive effect, mite class, coleoptera and homoptera pest there is high activity, and do not produce and intersect with other crops, emamectin-benzoate to lepidopterous insecticidal activity than the high several times of Avermectin, to the toxicity of warm blooded animal than the low several times of Avermectin, the active constituent content that use in the field only as Avermectin 1/5 or lower, soil and in easily degraded noresidue, free from environmental pollution, in the routine dose scope to useful insect and natural enemy, people, animal safety, can with most of combined use of pesticides.Domestic existing many enterprises produce this product, but because the manufacturing cost height, market price height, and application units' area control cost height in the agricultural production, the peasant is difficult to accept, and this medicine is to fishes and shrimps, honeybee toxicity height, uses in places such as water sources to be subjected to certain limitation.
Fluorine worm nitrile (fipronil) is the Phenylpyrazole insecticides, and insecticidal spectrum is wide, mainly is the fluoride metabolism that hinders the control of insect γ-An Jidingsuan, and a series of important pests such as Lepidoptera, fly class and coleoptera are had very high insecticidal activity.But the quick-acting of fluorine worm nitrile agricultural chemicals is poor slightly, and agricultural chemicals price height is extensive use of it and is restricted.In order to make this toxicity height of emamectin-benzoate, insecticidal spectrum is wide and can adapt to China rice grub to the agricultural chemicals of advantages such as pest controling effects such as snout moth's larva are good and prevent and treat market, can in the rice disease and pest integrated control, play better effect, it is reasonably composite that the present invention adopts moderately toxic fluorine worm nitrile to carry out with it, and strengthening quick-acting, enlarging insecticidal spectrum, reduce pesticide cost is the key point of this Recompounded pesticide.
Summary of the invention
The present invention seeks to overcome the deficiency that exists in the existing technology, propose to become lethane with Firponil compounded with the identical emamectin-benzoate of effect mechanism.Show as obvious synergistic effect after being mixed, in use improved insecticidal effect, reduced use cost, stop and delayed the development of pest resistance to insecticide, and better to the compatibility of environment.
