Rice fulgorid belongs to Insecta Homoptera (Homoptera) Delphacidae (Delphacidae) insect.Popular name fire midge worm.Inhale the plant juice crops such as paddy rice of causing harm with thorn.Frequent species has brown planthopper (Nilaparvata lugens), white-backed planthopper (Sogatella furcifera) and small brown rice planthopper (Laodelphax striatellus).Rice fulgorid is caused harm to paddy rice, removes directly to sting and inhales juice, makes growth retardation, and the rice clump is agglomerating withered when serious, even outside the dead stalk in field lodges entirely, lays eggs and also can stab plant, destroys conducting tissue, hinders nutriment transportation and the viral disease that spreads disease, and causes very large loss.
The applicant has at first carried out the research that prescription screens to ethyl multiple killing teichomycin and thiacloprid, the insecticidal activity of ethyl multiple killing teichomycin, two kinds of active ingredients of thiacloprid is very high, for the effect characteristics of two kinds of compositions, the object of indoor biometrics is decided to be brown planthopper, specifically test situation and the result is as follows:
Experimental drug adopts 90% ethyl multiple killing teichomycin and the former medicine of 95% thiacloprid, uses acetone that former medicine is dissolved, and is mixed with needed preparation by the patent application people.Matched proportion density according to setting is mixed with the desired concn liquid for subsequent use, and employed former medicine and auxiliary agent are other producers and buy.
The method of indoor biometrics is: adopt capillary micro intravenous drip method, capillary micro intravenous drip device volume is 1.0 μ L.With the micro intravenous drip device liquid is pursued a drop in the back side of brown planthopper 6 instar larvaes, each concentration is processed about 30 larva, the culture dish that it is 9cm that per 5 larvas are put into a diameter, the built-in a small amount of feed of ware is for taking food, in addition with 30 larvas of acetone drop in contrast.Larva after treatment still is placed in the receptacle, checks lethality behind the 48h.Data are processed with the SPSS software statistics.Obtain toxicity regression formula, the lethal concentration of 50, correlation coefficient etc., and obtain co-toxicity coefficient with 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 A=∑ of mixture preparation (toxicity index of certain medicine * percentage of this pharmaceutically active ingredient in mixture).
C was synergistic effect greater than 120 o'clock, less than 80 o'clock be antagonism, 80～120 o'clock is addition.
The different proportionings of table 1 are to the toxicity test result of brown planthopper
Analyze above-mentioned data determination result and show, when ethyl multiple killing teichomycin and thiacloprid different proportion were composite, the co-toxicity coefficient of all compounded formulas all had obvious synergistic effect respectively all greater than 120.After explanation is composite with two kinds of active ingredients, good synergistic effect can be arranged.By the indoor biometrics test, select the field trial that the larger prescription of CTC three, prescription five and the less prescription four of CTC are prevented and treated brown planthopper, determine the effect of prescription control brown planthopper; Simultaneously by with the Contrast on effect of ethyl multiple killing teichomycin, thiacloprid single dose, verify the synergistic effect after composite.
