Rice sheath blight disease claims again moire disease, is to be infected by Rhizoctonia solani Kuhn to fall ill, and how to fall ill under high temperature, super-humid conditions.Banded sclerotial blight is serious in the harm of south rice zone, is one of Major Diseases on the current Rice Production.This disease can make paddy rice not ear, and particle weight descends.
Along with a large amount of uses of agricultural chemicals, pesticide hazards problem and people become increasingly conspicuous to the concern of living environment.For the impact of present agricultural chemicals on environment, people begin more to be conceived to the more free of contamination biogenic pesticide of low toxic and environment-friendly, because biogenic pesticide is to utilize the antagonist properties between the microorganism to prevent and treat pathogen, this is more efficient and environmental protection than existing chemosynthesis composition, new varieties and the complex preparation of exploitation biogenic pesticide more and more are subject to people's attention at present, and two kinds of active ingredients that relate among the present invention are biogenic pesticide, show by our test in the past, two kinds of mixed pesticides that mechanism of action is different, can not only postpone resistance produces, can also improve drug effect, reduce usage amount, reduce peasant's dispenser cost.Therefore we are composite with tetramycin and Ningnanmycin, in order to enlarge fungicidal spectrum, reduce peasant's labour cost.
Summary of the invention
The purpose of this invention is to provide a kind of composition pesticide with synergistic effect and safety and environmental protection, realize improving drug effect, reduce the purpose of polluting, reducing cost.Be specifically related to the composite composition pesticide of tetramycin and Ningnanmycin.
Utilize composition pesticide of the present invention, be equipped with the known auxiliary agent of those skilled in that art, make formulation of the present invention with the known method of those skilled in that art, this formulation is aqua.
In the above-mentioned composition pesticide, the weight ratio of tetramycin and Ningnanmycin is 1:150～150:1.
Above-mentioned composition pesticide has following characteristics: 1. environmentally friendly, two kinds of active ingredients are biogenic, and are very little to environmental influence; 2. bactericidal action is strong, utilizes the antagonism between the microorganism that Oomycete class plant disease is had very strong control efficiency; 3. the adhesive ability at plant surface is strong; 4. two kinds of compositions are without obvious cross resistance, and complex preparation has obvious synergistic effect; 5. delay the generation of active ingredient resistance, reduce peasant's labour cost.
Embodiment
For determining tetramycin and two kinds of composite synergistic effects of active ingredient of Ningnanmycin, the applicant at first uses these two kinds of compositions to carry out the indoor biometrics test, and test method and result are as follows:
After at first having analyzed the effect characteristics of two kinds of active ingredients, the object that we will give birth to survey is decided to be thanatephorus cucumeris(frank) donk (Thanatephorus cucumeris), this Pseudomonas Basidiomycotina fungi, and sclerotium is dark brown, it is light brown to the taupe mildew that bacterium colony is.
The test method of indoor biometrics: adopt growth rate method to measure medicament to the inhibitory action of rice sheath blight disease mycelia growth.On the basis of preliminary experiment, from each medicament the germ mycelial growth inhibition rate is reached 5 concentration of design in 10%～90% scope, first that the former medicine of 95% tetramycin and the former medicine of 70% Ningnanmycin is for subsequent use with the liquid that the sterile water dissolving is made into series concentration, then with liquid in 1% ratio join melt and the PDA medium of cool to room temperature in, after fully shaking up, pour that to make the band medicine in the culture dish (Φ 90mm) of sterilization dull and stereotyped into, every processing repeats for four times, to add the blank that is treated to of sterile water; Card punch (Φ 5mm) picking Rhizoctonia solani Kuhn bacterium cake with sterilization, mycelia faces down aseptic inoculation in the central authorities with the medicine flat board, place 25 ℃ interior cultivation of constant incubator, cultivate and adopt the right-angled intersection method to measure colony diameter after 6 days, calculate each medicament to the EC of pathogen
50, and calculate according to the following equation toxicity index, the virulence of more different medicaments and bacteriostasis.Used former medicine is tested in above-mentioned living test and reagent is all bought from other producers.
