Abstract
The invention discloses a composite pesticide capable of preventing rice pests and belongs to the technical field of pesticides. The weight ratio of metaflumizone to guadipyr is 1:50 to 50:1. Ingredients of the composite pesticide further comprise additives and carriers. The metaflumizone and the guadipyr account for 5% to 60% of the total weight of the pesticide, the additives account for 5% to 30% of the total weight of the pesticide, and the rest is the carriers. Practical test results show that the composite pesticide has remarkable preventing effects on rice planthoppers and rice leaf folders. Compared with a common pesticide, the composite pesticide capable of preventing the rice pests has the following advantages that the effects on the rice planthoppers and the rice leaf folders are remarkable and labor and time are saved; a part of medium-high toxic pesticides can be replaced, the pesticide use amount is reduced, environmental pollution is reduced, and residual on agricultural products is decreased; the lasting period is long, compared with a single pesticide, the composite pesticide can reduce cost, and the composite pesticide capable of preventing the rice pests is safe for crops, natural enemies and the environment.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of composite insecticide of preventing and treating rice fulgorid and leaf-roller.
Background technology
Rice hoppers is the insect that a kind of harmfulness is large, reproduction speed is exceedingly fast, and the paddy rice of causing harm causes heading undesired, and thousand kernel weight alleviates, when serious, complete stool is withered, causing the significantly underproduction of paddy rice, but also can cause stripe virus disease by transmitted virus, is the insect of paddy rice keypoint control.On Rice Production, the control of rice fulgorid mainly relies on Imidacloprid, organic phosphor and built agent thereof, wherein high malicious organophosphorous pesticide bans use of, due to long-term single continuous use Imidacloprid, brown planthopper, small brown rice planthopper has produced obvious pesticide resistance to Imidacloprid, control efficiency sharply descends, especially 2006, brown planthopper in 2007, in the situation of the large generation of small brown rice planthopper, Imidacloprid mu consumption (effective content) is brought up to 3～4 grams, control efficiency only 30～40%, produce and bring serious difficulty to paddy rice, therefore, research and development high-efficiency prevention and control brown planthopper, the pesticide species of small brown rice planthopper, become the task of top priority.
Rice leaf roller belongs to the Lepidoptera Pyralidae, is the paddy rice Occurrence.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.Control pharmacopoeia in production, suitable control 1-2 instar larvae only, the lasting period is short, and to large instar weak effect, the repeatedly dispenser of peasant's need, just can control its harm.
Metaflumizone (metaflumizone) is a kind of brand-new compound, belong to the semicarbazones insecticides, 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.
Penta pyrrole worm guanidine (Guadipytr) is the nitro contracting aminoguanidine insecticides of new structure, chemical name: 1-nitro-3-[(6-chloropyridine-3-yl) methyl]-4-penta methene amido guanidine, toxicity is micro-poison, tool anabasine insecticide and sodium-ion channel suppress the structure effect of formulation insecticide, and the characteristics that the multiaction target is arranged, can prevent and treat piercing sucking insect.
Metaflumizone and penta pyrrole worm guanidine are composite, are that different insecticidal mechanisms mutually combine, and widen insecticidal spectrum, and gram slows down the generation of pest resistance to insecticide.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of composite insecticide of preventing and treating rice grub.
A kind of composite insecticide of preventing and treating rice grub of the present invention, its active ingredient is metaflumizone and penta pyrrole worm guanidine, wherein the weight ratio of metaflumizone and penta pyrrole worm guanidine is 1:50-50:1; Also include auxiliary agent and carrier in said composition, wherein metaflumizone and penta pyrrole worm 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, one or more of 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 one or more of kaolin, diatomite, water.
A kind of composite insecticide of preventing and treating rice grub of the present invention can be water dispersible granules, wetting powder or aqueous emulsion.
Insecticide of the present invention, through actual test, has significant control efficiency to rice fulgorid and leaf-roller.
Composite insecticide of the present invention is compared with common insecticides, has the following advantages: 1, rice fulgorid and leaf-roller are had a significant effect, save labor; 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.
