Rice-stem borer (Chilo suppressalis) popular name borer, borer eats into, and stalk worm etc. are the formidable opponents of paddy rice.Larva moth food stem stalk, can form the withered heart.If prevented and treated not in time, field often there will be a lot of withered heart seedling, and part field does not does not prevent and treat striped rice borer because of nursery period, and present field withered heart seedling ratio, up to 30%, even more than 50%, causes very large loss.The insecticide cost of exploitation New raxa is high, and effect is low, has a big risk, and it is composite to utilize existing agricultural chemicals to carry out, the generation of pest resistance to insecticide can be delayed, improve actual preventive effect, two kinds of composite synergistic effects certain in addition of composition, can 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 high and low poison of quick-acting, environmental protection Pesticidal combination.Be specifically related to chlorine fluorine cyanogen insect amide and ethyl spinosad is the composition pesticide of active ingredient.
In above-mentioned composition, the weight ratio of chlorine fluorine cyanogen insect amide and ethyl spinosad is 1:50 ~ 50:1.
Utilize above-mentioned composition, be equipped with the known auxiliary agent of those skilled in that art, formulation of the present invention can be made with the known method of those skilled in that art, comprise suspending agent and water dispersible granules.
The advantage that the present invention has and beneficial effect: 1, use two kinds of active ingredients composite, there is very strong synergistic effect; 2, strong drug action, quick-acting is good, and the lasting period is long; 3, formulation advanced person, environmental protection, can be good at the action effect playing active ingredient.
First applicant has carried out the research of recipe determination to chlorine fluorine cyanogen insect amide and ethyl spinosad, for the action character of two kinds of compositions, the object of indoor biometrics is decided to be striped rice borer, concrete test situation and result as follows:
The method of indoor biometrics is: adopt the former medicine of chlorine fluorine cyanogen insect amide of 90% and the former medicine of ethyl spinosad of 95%, according to the matched proportion density of setting, is mixed with the liquid of desired concn, for subsequent use.With reference to pesticide indoor bioassay test rule (agricultural industry criteria NY/T1154.14-2008), test adopts immersion method.The process of striped rice borer: appropriate rice leaf is soaked into the liquid 15s, takes out and naturally dry in ventilation, is positioned in the culture dish of diameter 9cm, and connect striped rice borer 3 instar larvae 15/ware, upper lid layer filter paper, adds a cover mark.If clear water control treatment, each process repeats for 4 times.Be positioned over 27 DEG C, 14h illumination cultivation is indoor, check result after 3d.Touch polypide gently with writing brush, be reactionlessly considered as dead worm.Data SPSS software statistics process.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 coefficient method representation that the co-toxicity of mixture preparation adopts Sun Yun abundant:
The theoretical toxicity index TTI=∑ of mixture preparation (percentage of this pharmaceutically active ingredient of the toxicity index ATI of certain medicine × in mixture).
Be synergistic effect when CTC is greater than 120, being antagonism when being less than 80, is addition when 80 ~ 120.
Table 1 different ratio is to the toxicity test result of striped rice borer
Analyze above-mentioned data determination result to show, chlorine fluorine cyanogen insect amide and ethyl spinosad different proportion composite time, the co-toxicity coefficient of all compounded formulas is all greater than 120, has obvious synergistic effect.Illustrate after composite for two kinds of active ingredients, good synergistic effect can be had.
Following instantiation is in order to further describe the present invention, but the present invention is absolutely not only only limitted to these embodiments following.In formula, percentage is all weight percentage, and the former medicine used and auxiliary agent are all bought from other producers.
Formulation examples is as follows:
Example one: 30.6% chlorine fluorine cyanogen insect amide ethyl spinosad suspending agent
Example two: 25.5% chlorine fluorine cyanogen insect amide ethyl spinosad water dispersible granules
Example three: 26% chlorine fluorine cyanogen insect amide ethyl spinosad suspending agent
Example four: 13% chlorine fluorine cyanogen insect amide ethyl spinosad suspending agent
Example five: 22% chlorine fluorine cyanogen insect amide ethyl spinosad suspending agent
Example six: 21% chlorine fluorine cyanogen insect amide ethyl spinosad suspending agent
Example seven: 33% chlorine fluorine cyanogen insect amide ethyl spinosad suspending agent
Example eight: 16% chlorine fluorine cyanogen insect amide ethyl spinosad suspending agent
