Самадов Мизамитдин, Сирожов Бурхан, Фатима Абдихомидова, Хамраев Жавлонбек

The purpose of this study is to develop a technology for producing water-soluble colloidal sulfur, which is one of the most important fungicides for protecting crops from diseases and pests, based on water-soluble high-molecular compounds, its composition, physical properties, and recommendations for use. The properties of water-soluble polymers were studied, optimal conditions for the formation of calloid sulfur were selected: polymer concentration - 8%, t = 700C, mixing speed-70 rpm, process time-20min, mass fraction of sulfur in colloidal solution - 46%, density - 1.35 g / cm3, pH - 7.0 1% solution.
