Abstract
An insecticide for rice field with broad spectrum is proportionally prepared from chlorpyrifos, hexaflumuron, emulsifier, suspending agent, diffuser, and water, solvent or filler.
Description
Technical field
The present invention relates to a kind of insecticide, especially a kind of insecticide of being prepared by chlopyrifos and fluorine bell urea belongs to technical field of pesticide.
Background technology
Chlopyrifos (chlorpyrifos), chemical name O, O-diethyl-O (3,5,6-trichloro-2-pyridyl) phosphorothionate (comprises chlorpyrifos-methyl O, O-dimethyl-O-3,5,6-trichloro-2-pyridyl phosphorothionate, CAS number: 5598-13-0), have another name called Le Siben (The Dow Agrosciences, LLC.'s trade name), pacify the people and find pleasure in, restrain and find pleasure in extremely.Chlopyrifos is a U.S. DOW chemical company in nineteen sixty-five development product at first, and it is a kind of efficient, organic phosphor desinsection miticide that toxicity is low, is a kind of utmost point broad spectrum pesticide, can prevent and treat on the ground and underground pests.Mainly by tag, stomach toxicity, stifling three kinds of mode of action Pest Control.Insecticidal spectrum can be compared with acephatemet, but toxicity is much lower, belongs to moderate toxicity, belongs to low toxicity in organophosphorus insecticide.Itself and soil organic matter adsorption capacity are extremely strong, are to substitute the comparatively ideal large-tonnage kind of high-toxic pesticide.China is extensive use of the ethyl chlopyrifos at present.
Fluorine phosphorus urea (hexaflumuron), chemical name 1-[3,5-two chloro-4-(1; 1; 2,2-tetrafluoro ethyoxyl) phenyl]-3-(2, the 6-difluoro benzoyl) urea; it is a kind of Benzoylbenzene methylurea insecticides; based on stomach poison function, have concurrently and tag and the food refusal effect, can suppress the synthetic of insect chitin; make larva when decortication, can not form new epidermis, cause polypide death.Characteristics are low toxicities, and the special efficacy phase is long, and are good to Lepidoptera, Diptera pest control efficiency, to most animal and human's class nonhazardous effects, and can be decomposed by Institute of Micro-biology.But its quick-acting is relatively poor, the cost height, and insecticidal spectrum is narrow.
Crops pesticide in usefulness mainly contains Imidacloprid, Buprofezin, benthiocarb, acephatemet, Hostathion at present.This insecticides can be prevented and treated the insect pest in the crops, but most product toxicity is higher, and not ideal to part insect pest effect, as acephatemet, progressively forbidden because of high poison, because being extensive use of, it has surpassed 10 years, various pests has also produced pesticide resistance, and using has limitation.Thereby desinsection new product, the especially application aspect the insecticide of rice field of being badly in need of developing low toxicity and low residue broad-spectrum high efficacy economy.
Summary of the invention
The technical problem to be solved in the present invention is: eliminate a kind of composite insecticide of back exploitation at the contour malicious insecticide of China's acephatemet, and harmless to crops, and environmentally friendly, adaptability is strong.
Main technical schemes of the present invention is: insecticide is by chlopyrifos and hexaflumuron compounded forming, and the proportioning of the two is a fluorine bell urea: chlopyrifos is 1: the 1-10 weight portion.Fluorine bell urea: the chlopyrifos proportioning is 1: the 1.5-6 weight portion.Its proportioning is chlopyrifos 0.2-99%, fluorine bell urea 0.1-50%, auxiliary agent 1 is 0.2-20%, auxiliary agent 2 is 0.1-20%, auxiliary agent 3 is 0.2-20%, wherein farm chemical emulgent, agricultural chemicals suspension agent, agricultural chemicals diffusant are respectively auxiliary agent 1, auxiliary agent 2, auxiliary agent 3, can be single, the two or three use simultaneously, and all the other are water, solvent or filler.
5-30wt% " chlopyrifos+fluorine bell urea " adds farm chemical emulgent, agricultural chemicals suspension agent or agricultural chemicals diffusant 0.2-20%, and surplus is water, solvent or filler.Or chlopyrifos is 10-80% during proportioning, fluorine bell urea 1-10%, and farm chemical emulgent, agricultural chemicals suspension agent or agricultural chemicals diffusant are 2-10%, all the other are water, solvent or filler.Be mixed with the various formulations such as " chlopyrifos+fluorine bell urea " suspensibility of 5-30%." chlopyrifos+fluorine bell urea " suspending agent with 20% calculates dosage: 80-120 (g/ mu).
Wherein the chemical structural formula of chlopyrifos is:
Chlopyrifos is used for the rice field separately and controls worm, and is active general, and it is slow to take effect, and with chemical structural formula is
Fluorine bell urea in conjunction with after the spread spectrum effect obvious, insecticidal action is accelerated, and increases substantially the activity of using separately separately.
" chlopyrifos+fluorine bell urea " of the present invention insecticide has tangible spread spectrum synergistic effect, have the effect that a medicine kills the multiclass insect, but a drug is killed the multiclass insect pest in control.Because its active raising can obviously reduce consumption, thereby play the safety that improves environment and food, favourablely fall this, increase production, tally with the national condition.
Embodiment
Farm chemical emulgent can select for use the staple kind as farming breast 400, Nongru-700, farming breast 300, agricultural newborn 3B2, calcium salt series calcium dodecyl benzene sulfonate farming breast 500, farming breast 1600, polyethers L-43, agricultural newborn 0206B, agricultural newborn 500-A, agricultural newborn 6202B, farm chemical emulgent 1600, farming breast 600, agricultural newborn BY series when the present invention prepared.Agricultural chemicals suspension agent normally is made up of effective ingredient, dispersant, thickener, antiprecipitant, defoamer, antifreezing agent and water etc., comprises aqueous suspension agent commonly used, colloidal suspending agent, concentrated suspension, micro-capsule suspension.The agricultural chemicals diffusant can be selected the MF-6 dispersant with high efficiency of NNO or the novel auxiliary reagent factory of Wuxi City, polyether-modified extraordinary organic silicon surfactant BD-3071 bleeding agent for use.Filler is market kaolin, bentonite, old soil, attapulgite, solvent etc.
" chlopyrifos+fluorine bell urea " insecticide component mix proportion scheme preferably is:
Chlopyrifos: 10-80%; Fluorine bell urea: 1-10%; Auxiliary agent 1:2-10%; Auxiliary agent 2:2-10%; Auxiliary agent 3:2-10%, all the other are filler.
Further the component mix proportion scheme of optimizing is:
Chlopyrifos: 5-8%; Fluorine bell urea: 1.5-6%; Auxiliary agent 1:3-8%; Auxiliary agent 2:4-7%; Auxiliary agent 3:4-8%; All the other are filler.
Or chlopyrifos: 17%; Fluorine bell urea: 3%; Auxiliary agent 1:3%; Auxiliary agent 2:2%; Auxiliary agent 3:1%, all the other are supplied for filler.
Be the test result of Suzhou precious band agricultural chemicals Co., Ltd below to product:
Chlopyrifos 18%, fluorine bell urea 2%, auxiliary agent 1 are the newborn 500 calcium salts series of farming calcium dodecyl benzene sulfonate 2%, and surplus is added into 100% for the second alcohol and water.More than be weight ratio, make the insecticide of 20% suspensibility.
| Processing mode | 20% " chlopyrifos+fluorine bell urea " suspensibility | 25% buprofezin wetting powder | Not medication |
| Dosage (g/ mu) | 20 | 40 | |
| The residue of pesticide number | 1.0 | 1.0 | 30 |
| Rice fulgorid preventive effect (%) | 96.7 | 96.7 | |
| The residual number of vertical volume worm | 1.5 | 25.0 | 27 |
| Preventive effect (%) | 94.4 | 7.4 | |
| Integrated control effect (%) | 95.6 | 52.1 |
Above-mentioned test result shows, the insecticide of 20% suspensibility (be chlopyrifos of the present invention+fluorine bell urea with 9: 1 weight proportion) has stronger insecticidal activity, and as vertical volume worm, the integrated control effect of plant hopper reaches 95.6%, obviously is better than buprofezin to the important insect pest in rice field.In addition through facts have proved that chlopyrifos+fluorine bell urea is with 6-8: 1 also has same effect.Above percentage is weight ratio.
