Spectrophotometric indicators of “Zamin-M” biopreparation immobilized with gypan flocculinate

Abstract

From the turn of the 20th century, biopreparations that quicken plant growth and development have been frequently employed. The accumulated knowledge of the mechanisms governing interactions between microorganisms and plants necessitates the use of minimal resources and energy in the targeted design of phytomicrobial systems and the optimization of their adaptability in order to increase soil fertility and plant productivity, increase plant yield, and increase plant resistance to diseases and unfavorable environmental conditions and stress factors. In the article today, enough experience has been collected on the scientific management of soil microorganism processes in the optimization of agricultural production and maintaining soil fertility, and it envisages the creation and use of microbiological preparations as the main link of intensive technologies in plant science. It is known that concentration of biomass of microorganisms using flocculants in the technological processes of production of bacterial preparations, after the stage of growth in enzymes, the stage of concentration of biomass of microorganisms from culture liquid is carried out.

Determination of the pathogenicity of the fungi Leveillula Saxifragacearum and Sphaerotheca Mors Uvae causing mildew disease

“…The disease first affected the leaf bands, then the lower part of the leaf and the main veins. On the back side of such leaves, a gray mesh-like powder formed, consisting of mycelia of the disease-causing fungus [18][19][20]. Due to the disease, the leaves did not develop well and became colorless.…”
