Description
The application is the applying date is on December 01st, 2010, and application number is 201010568461.0, and invention and created name is the divisional application of " a kind of Compositional type farmland, fruit tree miticide ".
Technical field
The present invention relates to field of pesticide preparation, relate to a kind of Compositional type farmland, fruit tree miticide specifically.
Background technology
The Agricultural Mites kind of China has kind more than 500, wherein endanger serious about kind more than 40, as tetranychid, Tetranychus urticae, goitre mite, Panonychus citri etc., their field-crops such as main harm fruit tree and cotton, wheat class, vegetables, tobacco, tealeaves, corn, soybean, peanut.Agricultural Mites volume is little, breeding is fast, strong adaptability, easily produces resistance, and under the suitableeest condition, 1 female one-tenth mite, 1 month breeding limit can, up to 10,000 bulls, be the pest communities of the most difficult generally acknowledged control.
Evil mite main harm crop and fruit tree leaf, the harmful characteristics of most Agricultural Mites is quite similar, all punctures plant epidermis cell with its elongated lancet, suck juice during harm, make part of damage chlorosis, withered or lopsided, only there is chlorosis spot in leaf initial stage of being injured, expand gradually, blade large area chlorosis near vein later, become brown, when mite mouth density is large, killed leaf is covered with silk screen, comes off in advance.After goitre mite harm fruit tree, the blade of crops or fruit, the position that is injured also can be stimulated to form mite goitre.Except directly endangering, some kinds or the communication media of the viroses of plant, the many mite classes as Eriophyoidea can propagate the viroses of plant, and the part mite class that Pyemotidae fringe mite belongs to Siteroptes spp. can propagate fungal disease.Warehouse evil mite casting off a skin and excreta can pollute the agricultural product of storage, make it generate heat to go mouldy, variable color with bad smell, after the agricultural product of band mite and contact human skin, also can bring out fash.
Of a great variety for preventing and treating the harmful miticide hidden from market, have crop unsafe amidine class, organic phosphates, the contour malicious miticide of organochlorine class; Have low to person poultry toxicity, to mite class effective chrysanthemum ester class miticide, but the lasting period is short, repeatedly will use, and produce cross resistance.At present hide agent from for killing of preventing and treating that evil hides from and mostly be selectivity miticide, toxicity is low, to people and animals, natural enemies security, it is long to kill the mite lasting period, as pyridaben (sweeping mite clean), propargite (mite must gram), Hexythiazox, Avermectin (Long Weikang) etc., but some optimum control state are single, and some costs are high, the residual height had is unsatisfactory to Agricultural Mites control efficiency.
Summary of the invention
In view of this, the object of the invention is to provide a kind of Compositional type farmland, fruit tree miticide efficiently.
For realizing object of the present invention, the present invention adopts following technical scheme:
A kind of miticide composition, is made up of second mite azoles and clofentezine.
The research and development of Yi Manzuoshi SUMITOMO CHEMICAL KCC, belong to the miticide of diphenyloxazole quinoline derivant, its mechanism of action suppresses the formation of mite class embryo and young mite to the molting process becoming mite, if all there is remarkable control efficiency to the ovum of mite pest, young mite mite, be mainly used in control citrus red mite, hawthron spider mite, Tetranychus urticae etc.In addition, second mite azoles using dosage is low, registration using dosage 5000-7500 times of liquid; Rain fastness is strong, and the lasting period reaches 50 days; To crop and Environmental security, on beneficial insect almost without impact, the needs of the harmful pests comprehensive regulation can be met; To female one-tenth mite, there is good sterile effect, though directly mite can not be killed into, effectively can reduce follow-on insect population radix.
Clofentezine is the organic nitrogen heterocyclic contact killing type acaricide agent that a kind of activity is very high, if have good activity to children mite, if suppress the molting process of children mite, its medicament has stronger penetration, to temperature-insensitive, the four seasons all can be used, and drug effect is slower, but the lasting period is longer, be applicable to the multiple harmful mite on the crop such as fruits and vegetables, cotton.
Wherein, as preferably, the percentage by weight of second mite azoles of the present invention and clofentezine is 1 ~ 99:1 ~ 99.
After different acaricidal activity component mixing, each active component is due to the difference of composition, structure, physicochemical property, makes the synergy between each active component be typically expressed as synergistic effect, summation action or antagonism.So-called synergistic effect is exactly the mutual synergism between different material, and its effect produced is greater than the sum total of each composition effect; And summation action is exactly the sum total that its effect produced equals each composition effect; When antagonism refers to that two kinds of materials act on living organism, a kind of material disturbs the effect of another kind of material, or the effect of interfering with an opponent each other, makes the phenomenon that general effect declines.
Evaluate the mixed interaction of two kinds of different acaricidal activity components and usually adopt calculating co-toxicity coefficient method, wherein, co-toxicity coefficient is obviously greater than 100 for synergistic effect, and co-toxicity coefficient is significantly less than 100 for antagonism, and co-toxicity coefficient=100 are summation action.The present invention, according to Sun Yunpei (Sun Y-P) method, calculates co-toxicity coefficient and evaluates second mite azoles effect mixed with clofentezine, result display, and the percentage by weight of second mite azoles and clofentezine is that the co-toxicity coefficient of 1 ~ 99:1 ~ 99 is all greater than 100.By indoor and outdoors biological activity determination test find, described second mite azoles and clofentezine composite, so that the ratio of 1 ~ 99:1 ~ 99 is used in combination, there is notable synergistic effect.
It is further preferred that the percentage by weight of described second mite azoles and clofentezine is 1:6 ~ 9.
Present invention also offers a kind of miticide, its active component is made up of miticide composition of the present invention.
Wherein, as preferably, it is 1% ~ 99% that miticide composition of the present invention accounts for described acaricidal percentage by weight.
Miticide of the present invention can make wetting powder, missible oil, suspending agent, microcapsule suspending agent or water dispersible granules by miticide composition of the present invention and customary adjuvant as required.
Experiment shows, miticide of the present invention can prevent and treat farmland and fruit tree evil mite effectively, therefore, present invention also offers the application of described miticide in control farmland, fruit tree evil mite.
