Embodiment 1

[0031]A bacterial strain capable of producing fungicidal agricultural antibiotics, whose scientific name is Streptomyces tauricus ECO00008, has been preserved in the General Microorganism Center of China Microbiology Culture Collection Management Committee on April 17, 2006, and has been registered in The volume number is CGMCC No.1682. The cell wall of the strain contains L, L-diaminopimelic acid, the whole cell sugar hydrolyzate contains galactose and arabinose, and the cell wall is type I. The strain grows well on Chaspor, glycerol-asparagine, inorganic salt-starch, yeast extract-malt extract, oatmeal, potato extract and nutrient agar medium; the morphological characteristics on Chapei agar medium are: The colony is white, round, fluffy on the surface, with more hyphae growing on the edge, with protrusions in the middle of the colony, uneven protrusions, and a petal shape of more than 4 petals; the basal hyphae and aerial hyphae are filamentous, not Regular branching, gene...

Embodiment 2

[0043] Dilute the new fosfoamycin A finished product prepared in Example 1 to 50-200 mg / liter, respectively use tricyclazole (75% wettable powder), sclerotin (40% wettable powder), and sclerotin Because (50% wettable powder) and chlorothalonil (75% wettable powder) are used as contrast agents, clear water is used as a blank control, and the finished product of test new phosphazomycin A is effective against rice blast, tobacco red spot, tomato gray mold and The control effect of capsicum anthracnose. The test results show that the new fosfoamycin A can effectively control rice blast, tobacco red spot, tomato gray mold and capsicum anthracnose, and the dosage is significantly lower than that of the control agent. The test results are shown in Table 3 to Table 6.

Abstract

The invention provides an agricultural fungicide taking new phosphorus and nitrogen mycin A as an effective ingredient, as well as preparation method and application thereof. The preparation method of the agricultural fungicide comprises the following steps of: firstly culturing Streptomyces tauricus ECO 00008 with the preservation number of CGMCCNo. 1682; then separately extracting a fermentation culture; breaking the wall of mycelium with acetone or methanol and mixing with a fermentation supernate; and absorbing by macroporous absorption resin for separation; eluting by the acetone or the methanol; concentrating or further purifying an eluent so as to obtain the new phosphorus and nitrogen mycin A; and then adding a carrier or an auxiliary agent so as to obtain a finished product. Test results show that the agricultural fungicide WYLZ-1349 has good effect especially in preventing and controlling rice blast, tobacco brown spot, tomato gray mold and pepper anthracnose and has small using amount, low using cost for peasants, wide usable range, and the like compared with the traditional medicament.

Description

technical field [0001] The invention belongs to the technical field of pesticide production, and in particular relates to a preparation process of a new agricultural antibiotic capable of preventing and treating fungal diseases of crops. Background technique [0002] At present, human beings have increasingly strict requirements on the environment, and the development of chemical pesticides is becoming more and more difficult, and the success rate is getting lower and lower. After decades of screening, almost all imaginable chemical structures have been covered. For this reason, the world's industrially developed countries and major pesticide companies are looking for new development points. At the same time, in order to find new lead compounds, the research and development of pesticides has entered the era of returning to nature, that is, looking for developable pesticides or pesticides from natural products. lead compound. Because natural products have undergone long-ter...
