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 agricultural chemicals that tetrachloro insect amide and chlorfenapyr are active ingredient.
In above-mentioned Pesticidal combination, the weight ratio of tetrachloro insect amide and chlorfenapyr is 1:50～50:1.
Utilize above-mentioned Pesticidal combination, be equipped with the known auxiliary agent of those skilled in that art, with the known method of those skilled in that art, can make formulation of the present invention.Its formulation that can process is suspending agent, water dispersible granules.
The advantage that the present invention has and beneficial effect: 1, desinsection scope is wide; 2, the lasting period is long; 3, low toxicity, noresidue, nuisanceless, environmentally safe; 4, use compound formulation, the reduction during all than single uses of the consumption of two kinds of insecticides, thus improved insecticidal effect, increased safety, reduced environmental pollution.
Rice leaf roller (Cnaphalocrocis medinalis Guenee) belongs to Lepidoptera, Pyralidae.Another name is scraped blue or green worm.Distribution North gets Heilungkiang, the Inner Mongol, reach the national Ge Dao district in Taiwan, Hainan in the south.The paddy rice of mainly causing harm, sometimes cause harm wheat, sugarcane, grain, grassy weed.The feature that causes harm is sewed the vertical volume of silk rice leaf adult bud with larva, and larva is hidden to occupy and wherein takes food mesophyll, only stays epidermis, forms white streak, causes paddy rice thousand kernel weight and reduces, and blighted grain increases, and causes the underproduction.
First applicant has carried out to tetrachloro insect amide and chlorfenapyr the research that formula screens, the insecticidal activity of tetrachloro insect amide, two kinds of active ingredients of chlorfenapyr is very high, effect feature for two kinds of compositions, is decided to be rice leaf roller by the object of indoor biometrics, and concrete test situation and result are as follows:
Experimental drug adopts 95% tetrachloro insect amide and the former medicine of 97% chlorfenapyr, uses acetone that former medicine is dissolved, and by patent application people, is mixed with needed preparation.Matched proportion density according to setting, is mixed with desired concn liquid standby, and the former medicine using 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 micro intravenous drip device by liquid by a drop in the back side of rice leaf roller 3 instar larvaes, each concentration is processed the larva of 30 left and right, every 5 larvas are put into the culture dish that a diameter is 9cm, and the built-in a small amount of feed of ware, for taking food, is separately used 30 larvas of acetone drop in contrast.Larva after treatment is still placed in receptacle, checks lethality after 48h.Data are processed by SPSS software statistics.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=∑ of mixture preparation (the toxicity index ATI of certain medicine * percentage of this pharmaceutically active ingredient in mixture).
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 rice leaf roller
Analyze above-mentioned data determination result and show, when tetrachloro insect amide and chlorfenapyr different proportion are composite, the co-toxicity coefficient of all compounded formulas is all greater than 120 respectively, all has obvious synergistic effect.After explanation is composite by two kinds of active ingredients, can there is good synergistic effect.Wherein the co-toxicity coefficient of proportioning five has reached 171.81 especially, for the highest in all proportionings.
