Abstract

The invention discloses a composite pesticide containing metaflumizone and ethofenprox. The composite pesticide is characterized in that the weight ratio of the metaflumizone to the ethofenprox is 1:50-50:1. The composite pesticide also comprises auxiliaries and a carrier. The metaflumizone and the ethofenprox account for 5-60 percent of the total weight of the pesticide; the auxiliaries account for 5-30 percent of the total weight of the pesticide; the carrier accounts for the rest of the total weight of the pesticide. An actual test shows that the pesticide disclosed by the invention has an obvious preventing and treating effect on rice planthopper and cnephalocrocis medinalis. Compared with a conventional pesticide, the composite pesticide has the advantages that the composite pesticide has the obvious effect on the cnephalocrocis medinalis and can replace partial medium-toxicity and high-toxicity pesticides, the drug using amount can be reduced, and the environment pollution and the residues of agricultural products can be alleviated; the advantage of long lasting period is realized; compared with a single medicine, the pesticide has the advantage that the cost can be reduced. The composite pesticide is safe to crops, natural enemies and the environment.

Description

A kind of composite insecticide that contains metaflumizone and ether chrysanthemum ester

Technical field

The invention belongs to technical field of pesticide, relate to a kind of insecticide of preventing and treating rice fulgorid and leaf-roller.

Background technology

Rice leaf roller belongs to the Lepidoptera Pyralidae, is a kind of of the often property sent out insect pest of paddy rice.Rice plant of tillering stage is injured affects its normal growth; Middle and later periods is injured, and affects output more obvious, and particularly sword-like leave is injured the later stage, causes not plump paddy rate to increase, and loss is serious.Adult is hidden by day and come out at night, and the light of becoming is arranged, become green and the characteristic of trooping.Ovum is loose to be originated on blade, usually take blade back as many, and newly hatched larvae is climbed to the blade tip leaf roll and taken food, and slightly large larva pierces in the leaf heart, leaf sheath or on blade face and stings food mesophyll, and weaves silk the vertical clove hitch bud in the both sides of leaf.Knot is just eaten mesophyll and epicuticle along vein after bud well in bud, and killed leaf presents strip tikka different in size.After larva is aging, in the plant bottom and leaf sheath section again tie bud and pupate.A larva edible harmful 5-9 sheet leaf in all one's life, it is withered white that killed serious field presents a slice.Along with the popularization of hybrid rice and short-stalked variety and the change of cropping system, habitat and Feeding Condition are all better in recent years, so rice leaf roller breeds soon, survival rate is high, and rice hazard is on the rise.In production, control medication major part is built agent, suitable control 1-2 instar larvae only, and the term of validity is short, to large instar weak effect, the repeatedly dispenser of peasant's needs.

Ether chrysanthemum ester is that a kind of insecticidal activity is high, the speed of knocking down is fast, the lasting period is longer, the various pests such as Lepidoptera, Semiptera, coleoptera, diptera is had to efficient ethers insecticide, to crop, natural enemies security.Chemical name is 2-(4-ethoxyl phenenyl)-2-methyl-propyl-3-phenoxy benzyl ether, molecular formula: C25H28O3.

Metaflumizone (metaflumizone) is a kind of brand-new compound, belong to the semicarbazones insecticides, Universal Chinese character title: metaflumizone, chemical name (IUPAC): (E+Z)-2-[2-(4-cyano group benzene)-1-(3-trifluoromethylbenzene) ethylidene]-N-(4-trifluomethoxybenzene) hydrazine carbonyl oxamides; Molecular formula: C24H16F6N4O2.The mechanism of action uniqueness of metaflumizone, itself has insecticidal activity, does not need bioactivation, with existing each insecticides without cross resistance.Metaflumizone can be prevented and treated larva, the adult of various places lepidoptera pest and some coleoptera effectively, can also be for preventing and treating the insects such as ant, termite, fly class, cicada dung beetle.

Summary of the invention

Technical problem to be solved by this invention is to provide a kind of composite insecticide that contains metaflumizone and ether chrysanthemum ester with control leaf-roller of better control efficiency.

A kind of metaflumizone and composite insecticide of ether chrysanthemum ester of containing of the present invention, its active ingredient is metaflumizone and ether chrysanthemum ester, wherein the weight ratio of metaflumizone and ether chrysanthemum ester is 1:50-50:1; Also include auxiliary agent and carrier in said composition, wherein metaflumizone and ether chrysanthemum ester account for the 5%-60% of insecticidal total weight, and auxiliary agent accounts for the 5%-30% of insecticidal total weight, and all the other are carrier.

Wherein said auxiliary agent is lauryl sodium sulfate, ethoxylated dodecyl alcohol, lignosulfonates, sulfonic acid polyformaldehyde condensation product (NNO), polyethylene glycol, ammonium sulfate, sodium carboxymethylcellulose, sodium butylnaphthalenesulfonate, 1-METHYLPYRROLIDONE, alkyl benzene calcium sulfonate, phenethyl phenol mela mine-formaldehyde resin polyoxy ethyl ether, ethylene glycol, silicone compound, xanthans, aluminium-magnesium silicate.

Wherein said carrier is kaolin, diatomite, water.

Of the present inventionly contain metaflumizone and the composite insecticide of ether chrysanthemum ester can be water dispersible granules, wetting powder or aqueous emulsion.

Insecticide of the present invention, through actual test, has significant control efficiency to leaf-roller.

Composite insecticide of the present invention is compared with common insecticides, has the following advantages: 1, leaf-roller is had a significant effect; 2, high malicious insecticide in can Substitute For Partial, reduce dosage, reduce the residual of environmental pollution and agricultural product; 3, have advantages of that the lasting period is long, compare with single medicament, can reduce costs.4, to crop. natural enemy. Environmental security.
