Rice-stem borer (Chilo suppressalis) popular name borer, borer, moth stalk worms etc., are the formidable opponents of paddy rice.Larva moth food stem stalk, causes the withered heart, and striped rice borer has the strain of turning harm habit, and a Chilo spp larvae can endanger many strains paddy rice, causes dead leaf sheath, the withered heart.If control not in time, field often there will be a lot of withered heart seedlings, and part field is not is not prevented and treated striped rice borer because of nursery period, and field withered heart seedling ratio is up to 30% now, and part location, field withered heart seedling ratio exceedes 50%, causes very large loss.
Butene-fipronil and chlorine fluorine cyanogen insect amide are two kinds of compositions that insecticidal activity is very high, can overcome the insecticide that uses over a long time single type, the pesticide resistance causing by both are composite.Improve actual preventive effect, expand insecticidal spectrum, reduce drug cost.
Summary of the invention
The object of this invention is to provide that a kind of insecticidal activity is efficient, lasting effect is long, the composition pesticide of the high and low poison of quick-acting, environmental protection.Be specifically related to the Pesticidal combination that butene-fipronil and chlorine fluorine cyanogen insect amide are active ingredient.
Above-mentioned composition pesticide, the weight ratio of butene-fipronil and chlorine fluorine cyanogen insect amide is 1:50～50:1.
Utilize above-mentioned composition pesticide, be equipped with the known auxiliary agent of those skilled in that art, can make formulation of the present invention with the known method of those skilled in that art.Its formulation that can process is suspending agent, water dispersible granules and aqueous emulsion.
The outstanding feature that the present invention has is as follows: 1, active ingredient low toxicity, and residual low, safety; 2, quick-acting is good, and the lasting period is long; 3, use compound formulation, there is synergistic effect, reduce the amount of labour; 4, formulation advanced person, need not or use organic solvent less.
First applicant has carried out to butene-fipronil and chlorine fluorine cyanogen insect amide the research that formula screens, and for the effect feature of two kinds of compositions, the object of indoor biometrics is decided to be to striped rice borer, and concrete test situation and result are as follows:
The method of indoor biometrics is: the former medicine of butene-fipronil of employing 95% and 90% the former medicine of chlorine fluorine cyanogen insect amide, according to the matched proportion density of setting, be mixed with the liquid of desired concn, and for subsequent use.With reference to pesticide indoor bioassay test rule (agricultural industry criteria NY/T1154.14-2008), test adopts immersion method.The processing of striped rice borer: appropriate rice leaf is soaked to into the liquid 15s, take out in ventilation and naturally dry, be positioned in the culture dish of diameter 9cm, connect 15/ware of striped rice borer 3 instar larvaes, upper lid layer filter paper, adds a cover mark.If clear water control treatment, each processing repeats for 4 times.Be positioned over 27 DEG C, 14h illumination cultivation is indoor, check result after 3d.Touch gently polypide with writing brush, be reactionlessly considered as dead worm.SPSS software statistics processing for data.Obtain toxicity regression formula, the lethal concentration of 50, correlation coefficient etc., and obtain co-toxicity coefficient by the abundant method of Sun Yun.
The co-toxicity of mixture preparation adopts the abundant co-toxicity coefficient method representation of Sun Yun:
The actual measurement toxicity index of mixture preparation
The theoretical toxicity index TTI=∑ (the toxicity index ATI × percentage of this pharmaceutically active ingredient in mixture of certain medicine) of mixture preparation.
The co-toxicity coefficient of mixture preparation
it is synergistic effect that CTC is greater than at 120 o'clock, and being less than at 80 o'clock is antagonism, and 80～120 o'clock is addition.
The toxicity test result of the different proportionings of table 1 to striped rice borer
Analyze above-mentioned data and show, when butene-fipronil and chlorine fluorine cyanogen insect amide different proportion are composite, the co-toxicity coefficient of all compounded formulas is all greater than 120, has obvious synergistic effect.Illustrate after composite two kinds of active ingredients, can have good synergistic effect.
Following instantiation is in order to further describe the present invention, but the present invention absolutely not only only limits to following these embodiment.In formula, percentage is all weight percentage, and the former medicine using and auxiliary agent are all bought from other producers.
Formulation examples is as follows:
One: 30.6% butene-fipronil chlorine fluorine cyanogen insect amide water dispersible granules of example
Two: 24.8% butene-fipronil chlorine fluorine cyanogen insect amide water dispersible granules of example
Three: 11% butene-fipronil chlorine fluorine cyanogen insect amide suspending agents of example
