Abstract
The invention discloses a pesticide containing pyridalyl and emamectin benzoate and belongs to the technical field of pesticide prevention and treatment. The weight ratio of the pyridalyl to the emamectin benzoate is 1:50-50:1. The pesticide also comprises auxiliaries and a carrier. The pyridalyl and the emamectin benzoate 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 cnephalocrocis medinalis of rice. Compared with a conventional pesticide, the composite pesticide disclosed by the invention has the advantages that the pesticide has an obvious synergism effect on the cnephalocrocis medinalis when being compared with a single dosage, and the preventing and treating effect can be obviously enhanced; the pesticide 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 drug resistance of the cnephalocrocis medinalis to the single pesticide can be delayed; the advantage of long lasting period is realized; compared with a single medicine, the pesticide has the advantage that the cost can be reduced.
Description
Technical field
The invention belongs to the pesticide control technical field, relate to a kind of insecticide of preventing and treating rice leaf folder, banded sclerotial blight.
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 medicament, suitable control 1-2 instar larvae only, and the lasting period is short, and to large instar weak effect, the repeatedly dispenser of peasant's need, can control causing harm of leaf-roller.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of insecticide that contains pyridalyl and first dimension salt with control rice leaf folder of better control efficiency.
Pyridalyl and the composite insecticide of first dimension salt of containing of the present invention, its active ingredient is pyridalyl and first dimension salt, wherein the weight ratio of pyridalyl and first dimension salt is 1:50-50:1; Also include auxiliary agent and carrier in said composition, wherein pyridalyl and first dimension salt 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.
It is of the present invention that to contain the composite insecticide of pyridalyl and first dimension salt can be water dispersible granules, wetting powder or aqueous emulsion.
Insecticide of the present invention, through actual test, has significant control efficiency to rice leaf folder.
Composite insecticide of the present invention is compared with common insecticides, has the following advantages: 1, with single dose, compare this kind leaf-roller is had to obvious synergistic effect, can significantly improve control efficiency; 2, high malicious insecticide in can Substitute For Partial, reduce dosage, reduce the residual of environmental pollution and agricultural product; 3, can delay the pesticide resistance of leaf-roller to single insecticide, 4, have advantages of that the lasting period is long, with single medicament, compare, can reduce costs.
