Abstract

The invention discloses wettable powder of a streptomyces roseoflavus biological bactericide, which adopts diatomite as a matrix and comprises the following components: not less than 108 propagules of streptomyces roseoflavus strain 0116, and 4% of a wetting dispersant. It is determined that diatomite is used as a carrier and sodium lignosulphonate is used as the wetting dispersant. In addition, the strain wettable powder storage stability is determined by regular detection of the viable bacterial count, and results show that after strain wettable powder storage for 24 months, the viable bacterial count is more than 80%. The invention has the characteristics of short development period, low cost, simple process, and capability of being developed into various dosage forms, and is suitable for large-scale production. Since propagules of streptomyces roseoflavus strain 0116 is used as the main component of the wettable powder, the invention is suitable for large-scale production, and when compared with strain fermentation liquor, the invention greatly shortens the field using amount, and reduces packaging and transport cost.

Description

Technical field:

[0001] The invention relates to a diatomite-based Streptomyces roseus flavum biological fungicide wettable powder for preventing and controlling plant diseases. Background technique

[0002] At present, the prevention and control of plant diseases is mainly based on chemical pesticides. Their long-term use has caused great selection pressure on pathogenic bacteria and easy to produce drug resistance. Moreover, the high residue and high pollution of chemical pesticides have a serious impact on the environment and the safety of people and animals. Therefore, bio-pesticides with low toxicity and low residue have become a major trend in the development and production of pesticides. Hebei Agricultural College Students' Defense Office applied for two patents on biocontrol preparations on November 2, 2005 and June 9, 2009, namely "a biological fungicide and its preparation method, application number / patent number: 200510117421" And "a biological fungicide wettabl...
