Abstract
The present invention relates to an insecticidal composition of agricultural chemicals, which comprises chlorpyrifos and cyromazine. According to the result of an indoor bioassay experiment, obvious synergistic effect (CTC=158) can be obtained when the chlorpyrifos and the cyromazine are compounded in a certain proportion. According to the results of field experiments for controlling liriomyza sativae, the 1000-time solution of 25% of wettable powder of the chlorpyrifos and the cyromazine has the preventing effect of more than 90% in 10 days, and the preventing effect is equivalent to the preventing effect (87%) of the 1000-time solution of 48% of chlorpyrifos emulsifiable solution in 10 days, and the preventing effect (85%) of the 5000-time solution of 75% of cyromazine wettable powder in 10 days. The 25% of wettable powder of the chlorpyrifos and the cyromazine has no phytotoxicity or adverse effect on the experiment crops of cucumber, luffa, etc.
Description
Technical field:
The invention belongs to pesticide field, specifically a kind of agricultural insecticide composition.
Background technology:
Chlopyrifos is the phosphorothionate insecticides, have tag, stomach toxicity and fumigation action, can prevent and treat insects such as cotton bollworm, aphid, cabbage caterpillar, diamond-back moth, two spotted spider mite.Fly eradication amine belongs to the heterocyclic insecticide, and strong systemic action is arranged, and lures that Diptera larvae and pupa distort on form into, and adult eclosion is complete or suppressed.Chlopyrifos and fly eradication amine have been used for many years on producing, and insect constantly strengthens its resistance, and dosage constantly increases.The field result of use of maintenance and improvement chlopyrifos and fly eradication amine necessitates.
Summary of the invention:
The present invention is different with the mechanism of action of fly eradication amine medicament according to chlopyrifos, and it is composite to overcome or to delay the pest resistance to insecticide development, improves control efficiency; The expanding prevention spectrum.
A kind of agricultural insecticide composition is characterized in that containing chlopyrifos and fly eradication amine.
A kind of agricultural insecticide composition is characterized in that containing 1-50% chlopyrifos and 1-80% fly eradication amine.
A kind of agricultural insecticide composition is characterized in that chlopyrifos: fly eradication amine=24-1: 1
A kind of agricultural insecticide composition is characterized in that the preferred weight percent content of each component is:
Chlopyrifos: 1-50%;
Fly eradication amine: 1-80%;
Emulsifier: 3-15%;
Filler: surplus.
Synergism test of the present invention shows, two kinds of active ingredients of the present invention compositely in interval all have synergistic effect, i.e. chlopyrifos: fly eradication amine=24-1: 1 bigger
By said ratio, wetting powder, soluble powder that chlopyrifos of the present invention and the former medicine of fly eradication amine and an amount of emulsifier and filler can be processed into by those skilled in that art's known method.
Soluble powder those skilled in that art of the present invention can manufacture by known method.
Wetting powder is can homodisperse preparation in water, wetting powder of the present invention is except that being added with thinners such as white carbon black, precipitated calcium carbonate, potter's clay, diatomite or inert substance, it contains ionic or nonionic surface active agent (wetting agent, dispersant), for example: fatty alcohol polyglycol ether sulphate, fatty acid amide N-methyl Taurine sodium salt, sodium sulfate of polyethenoxy ether of fatty alcohol, neopelex-calcium, sodium lignin sulfonate-calcium, one or more materials among the SOPA etc., content are 1-30%; It is 0.1---20% that the present invention also comprises penetrant t, azone, the common consumption of YZ-901.
The present invention compares than prior art has following advantage:
1, the indoor biometrics result of the test shows, chlopyrifos and fly eradication amine are composite composite by a certain percentage, and obvious synergistic effect (CTC=158) is arranged.
2, the field test results of control Americal rice leaf miner proves, preventive effect in 1000 times of the 25% chlopyrifos fly eradication amine wetting powders 10 days is greater than 90%, and is suitable with preventive effect 85% in 5000 times of in 1000 times 10 of the 48% Le Siben missible oil day preventive effect 87%, the 75% fly eradication amine wetting powders 10 days.25% chlopyrifos fly eradication amine wetting powder is to no poisoning and harmful effects such as trial crops cucumber, sponge gourds.
3, composition of the present invention had both had quick-acting, and certain lasting effect etc. is also arranged.
