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.And the insecticide cost of the new kind of existing exploitation is high, effect is low, have a big risk, and it is composite to utilize existing agricultural chemicals to carry out, and can delay the generation of pest resistance to insecticide, improves actual preventive effect, expands insecticidal spectrum, reduces drug cost.
Suspension emulsion has the feature of missible oil, aqueous emulsion and suspending agent concurrently, active ingredient different two specific characters can be processed into a preparation, thereby reach minimizing cost of transportation, reduces the advantages such as labour intensity.
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 Pesticidal combination of the high and low poison of quick-acting, environmental protection.Be specifically related to the composition that chlorine fluorine cyanogen insect amide and chlopyrifos are active ingredient.
In above-mentioned Pesticidal combination, the weight ratio of chlorine fluorine cyanogen insect amide and chlopyrifos is 1:50～50:1.
Utilizing above-mentioned Pesticidal combination, 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, is suspension emulsion.
The advantage that the present invention has and beneficial effect: 1, active ingredient is composite, synergistic effect is strong; 2, quick-acting is good, strong drug action; 3, formulation advanced person, environmental protection; 4, the lasting period is long.
First applicant has carried out to chlorine fluorine cyanogen insect amide and chlopyrifos 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 chlorine fluorine cyanogen insect amide of employing 90% and 97% the former medicine of chlopyrifos, 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 theoretical toxicity index TTI=∑ (the toxicity index ATI × percentage of this pharmaceutically active ingredient in mixture of certain medicine) 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 determination result and show, when chlorine fluorine cyanogen insect amide and chlopyrifos different proportion are composite, the co-toxicity coefficient of all compounded formulas is all greater than 120 respectively, all 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: 35.7% chlorine fluorine cyanogen insect amide chlopyrifos suspension emulsion of example
