Abstract
The pesticide composition features its content including fipronil in 0.5-15 wt% and chlorpyrifos in 5-60 wt%. It has a co-toxicity coefficient of 125-145, a rice pest preventing and controlling effect as high as 90 %, quick acting, a persistent effective period over 15 days, and use cost lower than fipronil.
Description
Technical field
The present invention relates to a kind of agricultural chemical insecticide composition, particularly a kind of have tag, the insecticides of stomach toxicity and systemic action.
Background technology
Paddy rice is the staple food crop of China and country in Southeast Asia, is subjected to the harm of various pests in the growth process of riceplant, and various pests takes place simultaneously sometimes, serious threat the growth of paddy rice.Particularly snout moth's larva (striped rice borer, paddy stem borer, rice leaf roller) and plant hopper, big generation has in recent years brought great loss to agricultural production.The plant hopper of breaking out in a plurality of provinces in 2005 has been caused the total crop failure of many places paddy rice, and is very big to peasant's kind grain enthusiasm influence.
Fluorine worm nitrile is in recent years at a large amount of a kind of insecticides that use of China, be mainly used in the control of rice grub, fine to the striped rice borer effect, but its systemic action is poor, preventive effect to rice leaf roller, paddy stem borer and plant hopper is very poor, and the use cost height has limited a kind of popularization and use of good insecticide greatly.Chlopyrifos is a kind of organophosphorus insecticide, and moderate toxicity has stronger systemic action, and is very good to the preventive effect of rice leaf roller and plant hopper, plant hopper great outburst in 2005, and it has played important effect in the control insect pest aspect drawing out, retrieving economic losses.This agent is in China's large-scale production, and cost is low, and residual effect is moderate, and speed of action is fast, is used in a large number by the peasant.
Summary of the invention
The purpose of this invention is to provide the insecticides that a kind of toxicity is moderate, with low cost, insecticidal spectrum is wide, the mode of action is various, quick-acting is good.
The present invention is achieved like this, and it is characterized in that insecticides contains fluorine worm nitrile 0.5-15%, chlopyrifos 5-60%.
Described insecticides, its preferred version is: the content of fluorine worm nitrile is 1-5%, the content of chlopyrifos is 20-40%.
Described insecticides, its preferred version is: the content of fluorine worm nitrile is 1-3%, the content of chlopyrifos is 25-35%.
The chemical name of fluorine worm nitrile be (±)-5-amino-1-(2,6-two chloro-a, a, a-three fluoro-tolyls-)-4-trifluoromethyl-sulfinyl pyrazoles-3-carbonization nitrile, be known substance, produce by Bayer Hangzhou crop science Co., Ltd.
The chemical name of chlopyrifos is o, and o-diethyl-o-(3,5, the 6-trichloro-2-pyridyl) phosphorothionate is domestic production in enormous quantities material.
Described insecticides is made into missible oil, suspending agent, and missible oil is made through mixing to stir by former medicine, molten Ji, emulsifier (various anionic surfactant and nonionic surface active agent); Suspending agent is formed through the sand mill grinding by former medicine, water or organic solvent and serial auxiliary agent (as wetting agent, dispersion suspending agent, tackifier, stabilizing agent, antifreezing agent, anticorrosion colouring agent, defoamer, mineral wet goods).Concrete composite production technology and usual auxiliaries all belong to existing known technology, no longer state at this.
It is effective that the present invention prevents and treats rice grub, preventive effect can reach more than 90%, quick-acting is good, the lasting effect phase is more than 15 days, use cost is low, not only can overcome fluorine worm nitrile to the anti-heterodyne of paddy stem borer, rice leaf roller, plant hopper, cost height, deficiency that interior absorption is not strong, and can utilize that it is effective to striped rice borer, absorption is strong, cost is low in the chlopyrifos advantage.
Embodiment
The present invention is described in further detail below in conjunction with embodiment.In these examples, except that specified otherwise was arranged, all percentages all were weight percentage.
The fluorine worm nitrile 0.5% of filling a prescription, chlopyrifos 29.5% formulation missible oil or suspending agent
Prescription difluoro worm nitrile 1.0%, chlopyrifos 29.0% formulation missible oil or suspending agent
Prescription trifluoro worm nitrile 1.5%, chlopyrifos 28.5% formulation missible oil or suspending agent
Prescription tetrafluoro worm nitrile 2.0%, chlopyrifos 28.0% formulation missible oil or suspending agent
Above-mentioned prescription and 80% fluorine worm nitrile water dispersible granules and 40% toxicity tick missible oil compare test, and is as follows to co-toxicity coefficient and the test of pesticide effectiveness data of striped rice borer:
