Abstract
The invention discloses the Pesticidal combination of a kind of fluorine-containing lice sulfanilamide (SN) and pyrethroid, Pesticidal combination containing active components A and active component B, active components A is selected from fluorine lice sulfanilamide (SN), active component B is selected from any one compound following: gamma cyhalothrin, ether chrysanthemum ester, Biphenthrin, fenpropathrin, tefluthrin, and the weight ratio of active components A and active component B is 1: 80 ~ 60: 1.The present composition has greater activity to the various pests in various crop, and has obvious synergistic effect, expands insecticidal spectrum.And have that dosage is little, resistance of rainwater washing against, the obvious feature of synergy.
Description
Technical field
The invention belongs to technical field of pesticide, relate to the application of Pesticidal combination on crop pest of a kind of fluorine-containing lice sulfanilamide (SN) and pyrethroid.
Technical background
Pyrethroid is the broad spectrum pesticide that a class can prevent and treat various pests, its insecticidal toxicity than older generation insecticide as organochlorine, organic phosphor, carbamates improve 10 ~ 100 times.Pyrethroid has strong action of contace poison to insect, and some kind has stomach toxicity or fumigation action concurrently, but does not all have systemic action.Its mechanism of action upsets the normal physiological of insect nerve, make it by excited, spasm is dead to benumbing.Pyrethroid is because consumption is little, working concentration is low, therefore safer to people and animals, very little to the pollution of environment.Its shortcoming is mainly high to fish toxicity, also has injury to some beneficial insect, reuses for a long time and insect also can be caused to develop immunity to drugs.
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 synergy ratio.Study through inventor, find fluorine lice sulfanilamide (SN) and gamma cyhalothrin, ether chrysanthemum ester, Biphenthrin, fenpropathrin, tefluthrin mutually composite, there is good synergistic effect within the specific limits, and about fluorine lice sulfanilamide (SN) and gamma cyhalothrin, ether chrysanthemum ester, Biphenthrin, fenpropathrin, tefluthrin relevant composite, there is not yet relevant report at home and abroad at present.
Summary of the invention
The object of the invention is to propose a kind of Pesticidal combination with synergistic function, use cost is low, preventive effect is good fluorine-containing lice sulfanilamide (SN) and pyrethroid.
The Pesticidal combination of a kind of fluorine-containing lice sulfanilamide (SN) and pyrethroid, it is characterized in that containing active components A and active component B, active components A and active component B weight ratio are 1: 80 ~ 60: 1, described active components A is selected from fluorine lice sulfanilamide (SN), and active component B is selected from the one in gamma cyhalothrin, ether chrysanthemum ester, Biphenthrin, fenpropathrin, tefluthrin.The preferred weight ratio of active components A and active component B is 1: 40 ~ 30: 1; The weight ratio being more preferably fluorine lice sulfanilamide (SN) and gamma cyhalothrin is 1: 15 ~ 10: 1; The weight ratio of fluorine lice sulfanilamide (SN) and ether chrysanthemum ester is 1: 25 ~ 5: 1; The weight ratio of fluorine lice sulfanilamide (SN) and Biphenthrin is 1: 20 ~ 10: 1; The weight ratio of fluorine lice sulfanilamide (SN) and fenpropathrin is 1: 20 ~ 2: 1; The weight ratio of fluorine lice sulfanilamide (SN) and tefluthrin is 1: 20 ~ 2: 1.
Described Pesticidal combination can be made into wetting powder, water dispersible granules, suspending agent, suspension emulsion, microemulsion, aqueous emulsion, microcapsule suspending agent, microcapsule suspension-suspendinagent agent.
Described Pesticidal combination is for preventing and treating the insect of crop, and described crop comprises fruit tree, vegetables, cereal crops, fiber crop, legume crop.
Described insect comprises tea lesser leafhopper, cabbage caterpillar, aphid, mythimna separata, trialeurodes vaporariorum, cotton bollworm, beet armyworm, diamond-back moth, two spotted spider mite, leaf miner, peach fruit borer, rice fulgorid, brown planthopper, striped rice borer, rice leaf roller, oriental tobacco budworm, tea geometrid.
In the present composition, the content of active component depends on amount of application when being used alone, and also depends on mixed ratio and the synergistic effect degree of a kind of compound and another kind of compound, simultaneously also relevant with target pest.In usual composition, the weight percentage of active component is 2% ~ 90% of gross weight, is preferably 5% ~ 80%.According to different preparation types, active component content scope is different.Usually, liquid preparation contains the active substance of by weight 1% ~ 60%, is preferably 5% ~ 50%; Solid pharmaceutical preparation contains the active substance of by weight 5% ~ 80%, is preferably 10% ~ 80%.
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 2% ~ 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, thickener or defoamer.According to different dosage form, in preparation, stabilizing agent known in those skilled in the art, antifreeze etc. can also be contained.
Pesticidal combination of the present invention can by user before use through diluting or directly using.Its preparation can be prepared by processing method known in those skilled in the art, after mixing, then adds surfactant as one or more in dispersant, stabilizing agent, wetting agent, binding agent, defoamer etc. by active component with liquid flux or solid carrier.
