Abstract
The invention discloses a combination containing bacillus subtilis, kasugamycin and tricyclazole and an application of the combination in pesticides. It is found by studies that a mixture composited by a microbial agent (bacillus subtilis), agricultural antibiotics fungicide (kasugamycin) and chemical pesticides fungicide (tricyclazole) can not only improve the original efficacy for preventing and curing rice blast, rice sheath blight disease and the like but also can prevent and cure new disease, the current situation that the efficacy of the three are poor due to single agent form for a long time is changed, the use amount of chemical pesticide is effectively reduced, the residue of pesticides on rice is reduced, the crop quality is improved, and the food crop safety is guaranteed.
Description
Technical field
The present invention relates to biological pesticide technical field, be specifically related to a kind of composition containing bacillus subtilis, kasugarnycin and tricyclazole and application.
Background technology
China is Rice Production maximum in the world and country of consumption.Paddy rice Annual planting area about 2,860 ten thousand hectares, produces 1.85 hundred million tons, rice per year, accounts for 1/5 of global Monitoring of Paddy Rice Plant Area, account for 1/3 of View of World Rice gross yield.Paddy always produces every year and ranks first in the world, and average per unit area yield is 1.6 times of world average level.But along with Chinese national economy development and the raising of people's lives quality, more and more higher to the cry of grain security.In recent years, due to the impact of the factors such as weather, environment and planting patterns are unreasonable, rice fungus diseases evil is frequent to be occurred, and serious harm rice leaf, causes rice nutrition to lack, the general underproduction 10% ~ 20%, and severe one can reach more than 30%, sometimes even has no harvest.
For the control of rice fungus diseases evil, mainly at present to select from resistant rice cultivars, the aspect research such as the biological property of paddy rice germ, chemical control aspect is mainly still based on chemical agent.
Qiao Jinling etc. have studied the virulence of several bactericide to rice fungus diseases evil, compare the toxicity test of 13 kinds of bactericide to the common 5 kinds of fungies of paddy rice, comprise that alkene bacterium kills for examination bactericide, very spirit, detoxification, rice blast madly kill, rice seedlings peace, golden man of great strength, Isoprothiolane, prosperity, wither, sterilizing becomes, poison is clear, guarantor's standing grain is sharp and Fu meter Le.Be mainly chemical agent, wherein to the most obvious species medicine of fungi inhibitory action, conk inhibiting rate is (toxicity test that several bactericide does harm to rice fungus diseases, Qiao Jinling etc., agricultural modernization, the 2nd phase in 2012: 5 ~ 6) more than 80%.
The usage amount cumulative year after year of chemical bactericide, the chemical pesticide residue problem of cereal crops has a strong impact on food security, therefore, develops a kind of green, low toxicity, the biopesticide Shi Ge scientific research institution of environmental protection, the instant responsibility of enterprise.
In view of this, special proposition the present invention.
Summary of the invention
Undesirable in order to solve in prior art rice fungus diseases evil pesticide efficacy, and have the problems such as harmful substances is residual, the invention provides a kind of composition containing bacillus subtilis, kasugarnycin and tricyclazole.
Bacillus subtilis is the one of Bacillus, belongs to gram-positive bacteria.The subtilin that bacillus subtilis thalline produces in process of growth, polymixin, nystatin, gramicidins isoreactivity material have obvious inhibitory action to rice blast pathogenic bacteria, inducing plant self-defensive system resists the invasion of pathogen simultaneously, thus realizes the object of biological control.
Kasugarnycin, English name Kasugamycin, chemical name is (5-amino-2-methyl-6-(2,3,4,5,6-hydroxy-cyclohexyl oxo) tetrahydropyran-3-base) amino-α-IMDA, be a kind of farm antibiotics series bactericidal agent, have excellent preventive effect and therapeutic action to the rice blast on paddy rice.
Tricyclazole, English tricyclazole by name, chemical name is 5-methyl isophthalic acid, 2,4-triazol [3,4-B] benzothiazole, it is the special chemical bactericide of control rice blast, bactericidal action mechanism mainly suppresses the melanic formation of attachment spore, thus suppresses spore germination and attachment spore to be formed, and stops germ to invade people and reduces the generation of magnaporthe grisea spore.
Research finds, above-mentioned three kinds of compositions combine, and kasugarnycin and tricyclazole can not affect the biologic activity of bacillus subtilis, and the drug effect of three kinds of composition combinations is obviously better than being used alone or being combined between two.In addition, except rice blast, inventor finds that said composition has good control efficiency for rice sheath blight disease.
The present invention also provides the above-mentioned composition containing bacillus subtilis, kasugarnycin and tricyclazole preparing the application in agricultural chemicals.Preferably this agricultural chemicals is for preventing and treating paddy rice fungal disease.
