Abstract
The invention discloses a pesticide composition containing flufenoxuron and fenproximate. The ratio of flufenoxuron to fenproximate in parts by weight in the pesticide is 1: (1-10). The pesticide composition disclosed by the invention has obvious synergic effect, application dosage of pesticide is reduced, manpower and material resource are saved, and environmental pollution of the pesticide is reduced, thus the pesticide composition is applicable to preventing and controlling red spiders on fruit trees.
Description
Technical field
The present invention relates to a kind of composition pesticide, active ingredient is flufenoxuron and azoles mite ester, is used to prevent and treat the fruit tree two spotted spider mite.
Background technology
The resistance problem of pest is a global problem, is the emphasis problem that the agricultural science and technology worker pays close attention to always.Along with the continuity year in year out of insect chemical control, the increase and the non-science of agricultural chemicals usage amount are used agricultural chemicals, pest resistance is serious day by day, and the pest species that produces resistance is on the increase.
Owing to use agricultural chemicals improper, harmful mite is developed immunity to drugs after the sixties, the natural enemy population reduces, and the ecosystem is destroyed, and causes two spotted spider mite to become the most serious harmful mite of harm on the present fruit tree, and often wildness is caused disaster.To become mite, to be clustered in thorn suction juice on oranges and tangerines blade, spray and the fruit as if mite, young mite.Killed blade presents many canescence flecks, and full leaf canescence when serious causes a large amount of fallen leaves and spike top, influences tree vigo(u)r and output.During rampant the generation, fruit surface is covered with canescence chlorosis spot, and full fruit is pale, influences output.
Therefore, be badly in need of the control medicament of the two spotted spider mite of efficient, low toxicity, environmental protection.
Flufenoxuron belongs to the benzoyl area kind insect growth regulator, IGR, is chitin synthesis inhibitor, the equal tool characteristic of its insecticidal activity, insecticidal spectrum and speed of action, and good blade face anelasticity is arranged.Especially mite and the insect to mezzanine level has high activity; Be widely used on oranges and tangerines, cotton, grape, soybean, fruit tree, king's rice and the coffee; Planting property of control food mite class (thorn goitre mite, short hairs mite, Panonychus citri, rust mite, tetranychus telarius etc.) and many other insects; And good lasting effect is arranged, to predacious mite and insect safety.There is not the cross resistance problem with other existing miticides.
Azoles mite ester is the oximes miticide, and the E body is higher than Z body acaricidal activity, and the mode of action is main with action of contace poison, has knocking down and suppresses decorticating.It is wide to kill the mite spectrum, and has the desinsection effect of curing the disease concurrently.It is fast to kill mite speed.Azoles mite ester is used very extensive in China, in agriculture control of pest mite, brought into play important function.But, made the harmful mites in some areas produce pesticide resistance because the mixture listing that contains azoles mite ester is in a large number added in single use and using by turns with other miticides year after year.
Being mixed of different pesticide species is the common methods of the agriculture resistant insect of control.Through the formulation of pesticide screening, filter out rational prescription, can effectively improve actual control efficiency, reduce dosage, reduce cost, delay the generation of pest resistance to insecticide, prolong the service life of medicament, be the important means of the insect comprehensive regulation.The control fruit tree two spotted spider mite that is mixed of flufenoxuron and azoles mite ester does not still have report at present and uses.
Summary of the invention
The technical problem that the present invention solves provide a kind of efficient, low toxicity and the lasting period long, can effectively prevent and treat the fruit tree two spotted spider mite, help the composition pesticide that contains flufenoxuron and azoles mite ester of the insect comprehensive regulation.
For addressing the above problem, the technical scheme that the present invention adopted is: a kind of composition pesticide that contains flufenoxuron and azoles mite ester, and the ratio of weight and number of flufenoxuron and azoles mite ester is 1:1～1:10, preferably, the ratio of weight and number of worm urea and azoles mite ester is 1:1～1:5.
Described composition pesticide can be selected suitable auxiliary agent for use according to well known to a person skilled in the art method, is mixed with: the application forms that suitable agricultural such as missible oil, suspending agent, aqueous emulsion, microemulsion is used.
Described composition pesticide also contains the required usual auxiliaries of preparation pesticidal preparations; Usual auxiliaries is one or more the mixing in solvent, emulsifier, wetting agent, stabilizing agent, dispersant, thickener, PH conditioning agent, antifoaming agent, antifreezing agent, the packing agent etc.; Be known substance; Be various auxiliary agents commonly used in the pesticidal preparations, can change to some extent, do not have special qualification according to different situations.
Described composition pesticide is used to prevent and treat the fruit tree two spotted spider mite.
Composition pesticide described in the invention can the finished product preparation form provide, and promptly each material mixes in the composition, and the composition of composition also can single agent form provide, and directly in bucket or jar, mixes before the use, is diluted to desired concn then.
Composition pesticide provided by the invention adopts the method for spraying to use usually, also can adopt agricultural to go up other operation techniques of using as required.
Compared with prior art; The present invention has following beneficial effect: 1, composition pesticide provided by the invention; In certain ratio range, show obvious synergistic effect; The control efficiency of composition is significantly improved than single agent, has reduced using dosage, dispenser recruitment and the cost of agricultural chemicals simultaneously, has also reduced influence and residue of pesticide to environment.
2, the active ingredient mechanism of action of composition pesticide provided by the invention has nothing in common with each other, and the application of composition can delay or overcome the generation of pest resistance to insecticide, prolongs the service life of medicament, helps the comprehensive regulation of insect.
3, Pesticidal combination provided by the invention is to crops safety.
