Abstract
The invention discloses an insecticidal composition. Active components of the insecticidal composite comprise cyantraniliprole and (E)-N-[(2-chlorine-thiazole) methyl]-N-ethyl-N'-methoxy-2-nitryl vinylidene diamine in a weight ratio of (1:0.1) to (1:10), and the total weight of the active components accounts for 2%-80% of the insecticidal composition. The insecticidal composition provided by the invention has complementary insecticidal efficacy, expands an insecticidal spectrum, has a higher control effect on armyworms, aphids, mosquitoes and striped rice borer in comparison with single cyantraniliprole, has remarkable synergism and a good insecticidal fast-acting property, and has the advantage of low cost.
Description
Technical field
The present invention relates to a kind of Pesticidal combination.
Background technology
The chemical name of bromine cyanogen insect amide (have another name called cyanogen insect amide, the CAS accession number is 736994-63-1) is: 3-bromo-N-[4-cyano group-2-methyl-6-(methylamine formoxyl)-and phenyl]-1-(3-chloropyridine-2 base)-1H-pyrazoles-5-formamide.Structural formula is as follows:
The bromine cyanogen insect amide belongs to benzamides insect ryanodine receptor inhibitor, and mainly by inducing the insect ryanodine receptor, the regulation and control intracellular calcium ion discharges and shows and tag and stomach poison function.Be mainly used in the insects such as crop control snout moth's larva, plant hopper, leafhopper such as paddy rice, vegetables, fruit tree, cotton.
Chinese patent literature 102633740A discloses a kind of anabasine compound and its preparation method and application, wherein embodiment 1 discloses a kind of compound: (E)-N-[(2-chloro-thiazole) methyl]-N-ethyl-N '-methoxyl group-2-nitro ethenylidene diamines, its structural formula is as follows:
This compound belongs to second generation nicotinic insecticide, is the nAChR antagonist, affects the transmission of insect central nervous system choline.Be mainly used in the insects such as the crops such as paddy rice, fruit tree, vegetables and tealeaves prevent eliminating aphis, leafhopper, plant hopper.
At present, not yet find the bromine cyanogen insect amide with (E)-N-[(2-chloro-thiazole) methyl] the composite report of N-ethyl-N '-methoxyl group-2 nitro ethenylidene diamines.
Summary of the invention
The object of the invention is to address the above problem, provide a kind of and have obvious synergistic effect, quick-acting is good, insecticidal spectrum is wide, lower-cost Pesticidal combination.
The technical scheme that realizes the object of the invention is: a kind of Pesticidal combination, active component is by bromine cyanogen insect amide and (E) N--[(2-chloro-thiazole) methyl]-N-ethyl-N '-methoxyl group-2-nitro ethenylidene diamines forms.
The bromine cyanogen insect amide with (E)-N-[(2-chloro-thiazole) methyl]-weight ratio of N-ethyl-N '-methoxyl group-2-nitro ethenylidene diamines is 1: 0.1～1: 10.
Described active component gross weight is 2%～80% of Pesticidal combination gross weight.
This Pesticidal combination is made the upper applicable arbitrary formulation of agricultural by adding auxiliary agent and carrier, such as wetting powder, granule, suspending agent, microemulsion, soluble granule etc.
Take wetting powder as example, this Pesticidal combination is also to have following component except above-mentioned active component: be 1%～10% dispersant of composition total weight; 2%～5% wetting agent for composition total weight; 0.5%～5% stabilizing agent for composition total weight; 1%～80% carrier for composition total weight.
Described dispersant is a kind of in sodium lignin sulfonate, sodium naphthalene sulfonate or the naphthalene sulfonic acids calcium or two kinds; Described wetting agent is a kind of in lauryl sodium sulfate, sodium butylnaphthalenesulfonate, sldium lauryl sulfate, dodecyl sodium sulfate or the neopelex or two kinds; Described stabilizing agent is a kind of in hydroxypropyl cellulose, carboxymethyl cellulose or the epoxidized soybean oil or two kinds; Described carrier is a kind of in diatomite, potter's clay or the bentonite or two kinds.
The good effect that the present invention has: (1) Pesticidal combination insecticidal effect of the present invention is complementary, has widened insecticidal spectrum.And the control efficiency of mythimna separata, aphid, mosquito and striped rice borer is higher than bromine cyanogen insect amide single dose, have obvious synergistic effect, and desinsection quick-acting is good.(2) because (E)-N-[(2-chloro-thiazole) methyl]-price of N-ethyl-N '-methoxyl group-2-nitro ethenylidene diamines only has about 1/9 of bromine cyanogen insect amide, therefore Pesticidal combination of the present invention also has lower-cost advantage.(3) dispenser of Pesticidal combination of the present invention can prevent and treat various pests, is the substitute of high-toxic pesticide.
