Abstract
The invention discloses a kind of Pesticidal combination containing second worm nitrile, the principal character of said composition is: containing active components A, active component B, adjuncts Balance, wherein active components A is second worm nitrile, active component B is arbitrary a kind of in metaflumizone, Nylar, lufenuron, and the weight ratio of active components A and active component B is 60:1 ~ 1:60, composition makes wetting powder, water dispersible granules, suspending agent, suspension emulsion, aqueous emulsion, microemulsion, microcapsule suspending agent, micro-capsule-microcapsule suspending agent.The present composition can prevent and treat various pests, and has obvious synergistic effect, and has slow releasing function, decreases pesticide usage amount, and to person poultry safety, without poisoning, Environmental compatibility is good; The advantages such as preparation adhesion strength strengthens, resistance of rainwater washing against, and the lasting period is long.
Description
Technical field
The invention belongs to technical field of pesticide, relate to a kind of Pesticidal combination containing second worm nitrile.
Background technology
Second worm nitrile (ethiprole), molecular formula: C
13h
9cl
2f
3n
4oS, chemical name: sub-sulphur (sulphur) the acyl group pyrazoles of 5-amino-1-(2,6-dichloro-4-fluoromethylphenyl)-4-ethyl-3-itrile group, second worm nitrile is novel pyrazole insecticides, and insecticidal spectrum is wide.Disturb chloride channel by γ-aminobutyric acid (GARA), thus destruction central nervous system (CNS) normal activity makes insect lethal.The white clothing constraint comparison vertebrate of this medicine to insect GARA chloride channel is tightr.Thus very high selection toxicity is provided.Its mechanism of action is different from the main insecticide family such as pyrethroid, organic phosphor, carbamate, does not almost produce the chance of interactivity with the existing insecticide of majority.Therefore, it is the desirable standby kind of resistance management, can with the mixed pesticide of other chemical family, be used alternatingly.
But in the real process of agricultural production, the problem that pest control the most easily produces is the generation of pest resistance to insecticide.Different cultivars composition carries out composite, is to prevent and treat the very common method of resistant insect.Heterogeneity is carried out composite, according to practical application effect, judge certain composite be synergy, add and or antagonism.In most cases, the composite effect of agricultural chemicals is all additive effect, really has the seldom composite of synergistic effect, especially synergistic effect clearly, very high composite just less of co-toxicity coefficient.Find through inventor's lot of experiments, after second worm nitrile and metaflumizone, Nylar, lufenuron are composite, synergistic effect is remarkable, and Environmental compatibility is fabulous, considerably reduces pesticide usage amount.
Summary of the invention
The Pesticidal combination that the present invention proposes to contain in second worm nitrile and Nylar, metaflumizone, lufenuron any one two kinds of active components and appropriate amount of addition agent.
A kind of Pesticidal combination containing second worm nitrile, comprise active components A, active component B, adjuncts Balance, it is characterized in that: active components A is second worm nitrile, active component B is arbitrary a kind of in Nylar, metaflumizone, lufenuron, and the weight ratio of active components A and active component B is 60: 1 ~ 1: 60.
Described Pesticidal combination, is characterized in that: the weight ratio of active components A and active component B is 40: 1 ~ 1: 40.
Described Pesticidal combination, is characterized in that: the weight ratio of active components A and active component B is 20: 1 ~ 1: 20, is preferably 10: 1 ~ 1: 10.
Described Pesticidal combination, is characterized in that: composition makes wetting powder, water dispersible granules, suspending agent, suspension emulsion, aqueous emulsion, microemulsion, microcapsule suspending agent, micro-capsule-microcapsule suspending agent.
Described Pesticidal combination is for preventing and treating the application of insect on paddy rice, wheat, brassicaceous vegetable, tea tree, cotton, fruit tree, ornamental flower.
Described insect comprises: comprise thrips, stinkbug, curculionid, beet gelechiid, aphid, plant hopper, Bemisia tabaci, olethreutid, leaf miner, lima bean pod borer, scale insect, beet armyworm, prodenia litura, pear psyllid, rice indulge leaf snout moth's larva, cotton bollworm, pink bollworm, diamond-back moth, Hellula undalis, black cutworm, rice-stem borer.
At least containing a kind of surfactant in Pesticidal combination of the present invention, the dispersion of active component in water when being beneficial to use.Surface-active contents is 5% ~ 30% of total formulation weight amount, and surplus is solid or liquid diluent.Surfactant selected by Pesticidal combination of the present invention is known in those skilled in the art: can be selected from one or more in dispersant, wetting agent, emulsifier or defoamer.
Composition comprises following constituent content when making wetting powder: active components A 0.1% ~ 80%, active component B0.1% ~ 80%, dispersant 5% ~ 10%, wetting agent 2% ~ 10%, filler surplus.
By active components A, active component B, dispersant, wetting agent, filler mixing, mix in mixed cylinder, mix again after airslide disintegrating mill is pulverized, namely can be made into wetting powder product of the present invention.
Composition comprises following constituent content when making water dispersible granules: active components A 0.1% ~ 80%, active component B0.1% ~ 80%, dispersant 3% ~ 12%, wetting agent 1% ~ 8%, disintegrant 1% ~ 10%, filler surplus.
Active components A, active component B, dispersant, wetting agent, disintegrant, filler etc. are obtained together the particle diameter needed through air-flow crushing, obtain granulation materials.Item is quantitatively sent in fluidized bed granulating dryer through granulating and after drying, obtaining water dispersible granules product of the present invention.
Composition comprises following constituent content when making suspending agent: active components A 0.1% ~ 50%, active component B0.1% ~ 50%, dispersant 2 ~ 10%, wetting agent 2 ~ 10%, defoamer 0.1 ~ 1%, thickener 0.1 ~ 2%, antifreeze 0.1 ~ 8%, emulsifier 0.5% ~ 5%, water adds to 100%.
