Abstract
An emulsified Fujing-Di oil as agricultural insecticide for striped rice borer, plant hopper, cabbage caterpillar, etc is prepared from compounding fipronil (0.5-1.2%) with trichlorfon (40-55%), and then adding emulsifier (5-12%), stabilizer (0.5-2%), synergistic (0.5-2%) and solvent (the rest) through uniformly mixing by stirring. Its advantages include high effect, broad spectrum, low poison and simple preparing process.
Description
The present invention relates to a kind of agricultural insecticide.
Existing insecticide variety is a lot.But along with the generation of pest resistance to insecticide, the field control effect of many insecticides descends year by year, and insecticidal spectrum is narrower mostly.
The purpose of this invention is to provide a kind of novel agricultural insecticide, make its insecticidal spectrum wider, the field use cost is lower, and control efficiency better can delay and administer some pest resistance again.
Technical solution of the present invention is achieved in that
A kind of fluorine nitrile enemy missible oil, its difference from prior art is made up of weight components:
Fluorine worm nitrile 0.5～1.2% weight portion
Chlorophos 40～55% weight portions
Emulsifier 5～12% weight portions
Stabilizing agent 0.5～2% weight portion
Synergist 0.5～2% weight portion
Surplus is a solvent.
A kind of production technology of fluorine nitrile enemy missible oil is characterized in that comprising the following steps: successively
(1) with fluorine worm nitrile 0.5～1.2% weight portion, chlorophos 40～55% weight portions and solvent 28.5～38.5% weight portion mixing and stirring;
(2) add emulsifier 5～12% weight portions, stabilizing agent 0.5～2% weight portion, synergist 0.5～2% weight portion, and stir;
(3) add balance solvent, make total component reach 100%, and stir, leave standstill after sample analysis is qualified product.
Two kinds of agricultural chemicals of fluorine nitrile and chlorophos have been produced result in unexpected positive through prescription of the present invention with novel pesticide product fluorine nitrile enemy missible oil after technology is composite: compare with existing agricultural chemicals, it has obvious synergistic effect, and insecticidal spectrum is wide, the insecticide efficiency height; And can delay the generation of pest resistance, and to crop safety, to people and animals' low toxicity, can also promote that paddy rice takes root, increase and tiller and leaf chlorophyll, make increasing production of rice.Practice is the sole criterion for testing truth, and through field practical application and detection, product of the present invention is 188.2 to the co-toxicity coefficient of rice fulgorid, is 188.7 to the common toxin number of striped rice borer.Use with 133～150 gram fluorine nitrile enemy missible oil (fluorine-containing worm nitrile 1 gram and chlorophos 50～72 gram active ingredients)/mu, preventive effect to rice-stem borer is higher than 98.3%, suitable with single preventive effect with fluorine worm nitrile 2 grams (active ingredient)/mu, apparently higher than single preventive effect 64.3% with chlorophos 130 gram effective ingredient/mus.Under same dosage, fluorine nitrile enemy missible oil is higher than 88.2% to the preventive effect of rice leaf roller, with single suitable with fluorine worm nitrile preventive effect, apparently higher than single preventive effect 48.1% with chlorophos; Preventive effect to rice fulgorid is higher than 92.21%, and is suitable with single preventive effect with fluorine worm nitrile, apparently higher than single preventive effect 56.87% with chlorophos.The various insects such as snout moth's larva, plant hopper, thrips, Lissorhoptrus oryzophilus Kuschel, rice plant skipper and oryza chinensis on the paddy rice both can effectively prevented and treated and kill to product of the present invention, can effectively kill diamond-back moth on the crop such as vegetables, cabbage caterpillar, and soil insect again, reduce farming this 40%.Technology of the present invention is simple, easy to operate, do not produce the three wastes.In sum, the present invention has than obvious social and economic benefit reducing farming basis, kill pests, raising crop yield.
The present invention is further described below in conjunction with embodiment:
Embodiment 1
With fluorine worm nitrile 1% weight portion, chlorophos 50% weight portion and solvent 25% weight portion, stabilizing agent 2% weight portion, synergist 1% weight portion mixing and stirring, add emulsifier 8% weight portion then and stir, add solvent 13% weight portion again, continue to stir 30 minutes, after sample analysis is qualified, leave standstill product.The product composition of making is:
Fluorine worm nitrile 1% weight portion
Chlorophos 50% weight portion
Stabilizing agent 2% weight portion
Synergist 1% weight portion
Emulsifier 8% weight portion
Solvent 38% weight portion
Embodiment 2
With fluorine worm nitrile 0.65% weight portion, chlorophos 45% weight portion and solvent 30% weight portion mixing and stirring, adding each 2%, 2%, 12% weight portion of stabilizing agent, synergist, emulsifier then stirs, last power is gone into solvent 8.35% weight portion, continue to stir static product 30 minutes.This product contains:
Fluorine worm nitrile 0.65% weight portion
Chlorophos 45% weight portion
Stabilizing agent 2% weight portion
Synergist 2% weight portion
Emulsifier 12% weight portion
Solvent 38.35% weight portion
Embodiment 3
With fluorine worm nitrile 0.8% weight portion, chlorophos 54% weight portion, solvent 28% weight portion mixes earlier, adding each 1.5%, 2%, 11% weight portion of stabilizing agent, synergist, emulsifier then stirs, add solvent 2.7% weight portion at last, stirred 0.5 hour, leave standstill product.Product is made up of following component:
Fluorine worm nitrile 0.8% weight portion
Chlorophos 54% weight portion
Stabilizing agent 1.5% weight portion
Synergist 2% weight portion
Emulsifier 11% weight portion
Solvent 30.7% weight portion
