Study on preparation and transversal transport of peanut oil-based uniconazole emulsion in soil

Abstract

Uniconazole, as a broad-spectrum and efficient plant growth regulator, is easily hindered in soil transport, resulting in most drugs not being able to diffuse to plant roots and reducing their utilization efficiency. Based on the above problems, in this paper, peanut oil was used as the oil phase to prepare uniconazole oil in water emulsion. By constructing a transverse transport model soil column, the transverse transport capacity of the peanut oil-based uniconazole lotion in the soil column was investigated in terms of the dispersion mode of the lotion, the type of emulsifier, the concentration of the lotion, the flow rate of the lotion, and the transverse transport distance. Compared with the water dispersion formulation of uniconazole, the uniconazole lotion has a stronger transverse transport capacity than the water dispersant. When the concentration of uniconazole lotion is 500 mg·L^-1, the flow rate into the soil column is 1.23 mL·min^-1, and the transverse transmission distance is 40 cm, it has good transverse transmission capacity. The research results of this article provide a reference for the green and efficient use of uniconazole.
