Abstract
The invention belongs to the field of agricultural chemicals and discloses a complex insecticidal composition containing tolfenpxrad and diazinon and an application thereof. The insecticidal composition takes the tolfenpxrad and the diazinon as main active ingredients, wherein the weight ratio of the tolfenpxrad to the diazinon is (0.1-80):(0.5-80). The insecticidal composition can produce higher cooperative and synergistic action, overcome and delay drug resistance of pests, realize high pest-killing speed and long lasting period, reduce the cost of medication and enable the control effect to be better than that of a single agent. The insecticidal composition disclosed by the invention can be used for controlling lepidoptera pest, homoptera, thysanoptera or mite type pests on crops and particularly has special efficacy for controlling lepidoptera diamond back moths, cotton bollworms, asparagus caterpillars, thysanoptera thrips, mites and other pests, and the effects are obviously higher than those of the single agent.
Description
Technical field
The invention belongs to pesticide field, be specifically related to a kind of compound pesticide compositions and application thereof that contains Tolfenpyrad and diazinon.
Background technology
Tolfenpyrad (Tolfenpyrad), chemical name: 4-chloro-3-ethyl-1-methyl-N-{[4-(4-methylphenoxy) phenyl]-methyl }-1H pyrazoles-5-carboxylic acid amides, be the off-white color pressed powder, density (25 ℃): 1.18g/cm, vapour pressure (25 ℃):＜5 * 10Pa.Solvability (25 ℃): water 0.037mg/L, n-hexane 7.41g/L, toluene 366g/L, methyl alcohol 59.6g/L.Distribution coefficient (n-octyl alcohol/water) (25 ℃): log Pow5.61.Structural formula is:
The acute toxicity of Tolfenpyrad preparation is: rat oral LD50102 (hero), 83 (female) mg/kg; Its mouse oral LD50104 (hero), 108 (female) mg/kg.Acute dermal toxicity is relatively low, to rat, mouse LD50 all＞2000mg/kg.Lagophthalmos eyeball and skin there is moderate spread effect.
Tolfenpyrad is the novel pyrazole heterocyclic insecticidal/acaricidal agent of former Mitsubishi chemical company (its agricultural chemicals partly now belong to Japanese agricultural chemicals company) exploitation, its main mechanism is the oxidative phosphorylation that stops insect, also has ovicidal, presses down food, oviposition deterrence and bactericidal action.
Diazinon (diazinon) has another name called basudin, diazinon, and chemical name is: 0,0-diethyl-O-(2-isopropyl-4-first pyrimidine-6-first) phosphorothionate is broad-spectrum organophosphorous pesticide, has quick-acting.At plant leaf blade preferably permeability is arranged.Its mechanism of action is to suppress cholinesterase in the insect bodies.Structural formula is:
This kind have tag, stomach toxicity and stifling three kinds of modes of action, its insecticidal spectrum is wide, toxicity is lower, efficient equally to the ground soil insect, it is the desirable insecticide of control grain, fruit tree, vegetables and other economic crops insect pests, control efficiency to underground insect is particularly outstanding, also can dress seed and prevent and treat the soil insect of various crop, be particularly suitable for being applied to the production of pollution-free vegetable.
But diamond-back moth, cotton bollworm and thrips are under the condition of present long-term prescription, and resistance increases gradually, and the agricultural chemicals single dose descends gradually to the effect of control of insect.The inventor finds that after deliberation the synergistic complex of agricultural chemicals is expanding prevention spectrum and the effective measures that improve preventive effect, not yet finds up to now the Pesticidal combination of relevant Tolfenpyrad and diazinon.
Summary of the invention
The purpose of this invention is to provide a kind of compound pesticide compositions that contains Tolfenpyrad and diazinon, this Pesticidal combination is the multifunctional insecticide composition of control homoptera pest.
Another object of the present invention provides the application of this compound pesticide compositions on the preparation insecticidal materials.
The objective of the invention is to be achieved through the following technical solutions:
A kind of compound pesticide compositions that contains Tolfenpyrad and diazinon, this Pesticidal combination is take Tolfenpyrad and diazinon as main active ingredient, wherein, the weight ratio of Tolfenpyrad and diazinon is 0.1～80: 0.5～80, be preferably 0.5～50: 2～50, more preferably 0.5～10: 4～30, particularly preferably 1: 0.1～10.Effective ingredient is present in the composition with the synergy effective dose in this Pesticidal combination.
In compound pesticide compositions of the present invention, the two gross weight percentage composition in this compound pesticide compositions of Tolfenpyrad and diazinon is 3%～80%.Be preferably 5%～55%, most preferably 10%～40%.
Compound pesticide compositions of the present invention take Tolfenpyrad and diazinon as main active ingredient and insecticides adjuvant and excipient be mixed with any one formulation that allows on the agricultural chemicals, the preferred missible oil of described formulation, suspending agent, wetting powder, aqueous emulsion, microemulsion or water dispersion granule.
Auxiliary agent can adopt calcium dodecyl benzene sulfonate, alkylphenol polyoxyethylene, polyoxyethylene polyoxy third rare block compound (such as the newborn 33# of farming), polyoxyethylene nonylphenol ether, cyclohexanone, dimethylbenzene, solvent naphtha, water, antifreezing agent (such as propane diols), deionized water etc.Above auxiliary agent can alone or and usefulness.
The application of compound pesticide compositions on the insecticidal materials of preparation control lepidoptera pest, Homoptera, thrips or mite pest that contains Tolfenpyrad and diazinon of the present invention.
The application of compound pesticide compositions on the insecticidal materials of the insects such as preparation control Lepidoptera diamond-back moth, cotton bollworm, beet armyworm, thrips thrips or mite class that contains Tolfenpyrad and diazinon of the present invention.
Beneficial effect of the present invention compared with prior art: (1) is compared with single dose, said composition antagonism lepidoptera pest such as diamond-back moth, cotton bollworm and thrips insect thrips etc. have obvious synergistic function, overcome and delayed pest resistance to insecticide, the expanding prevention spectrum, desinsection speed is fast, has obviously improved control efficiency; (2) reduce control recruitment, drug cost; (3) alternative high-toxic pesticide; (4) have concurrently quick-acting and long-acting; (5) compare with the diazinon single dose with Tolfenpyrad, produce and the use cost reduction; (6) suppress lepidoptera pest, Homoptera, thrips and mite pest to the resistance enhancing of agricultural chemicals, its successful is higher than its single dose to be used.
