Novel formulation for enhancing efficiency of metribuzin.

The biological efficiency of systemic herbicide metribuzin in water dispersible granules (WG) and solution colloid concentrate (SCC) formulations was studied in field experiments. Metribuzin formulation in SCC state was prepared by the addition of a mixture of anionic and non-ionic surfactants and alkoxylated sorbitan esters as specific adjuvants. The ability of herbicide formulation containing Metribuzin in SCC state to provide increases in control of broadleaf and grassy weeds in comparison to WG was observed.

Novel formulation for enhancing efficiency of tebuconazole.

A novel formulation of tebuconazole in microemulsion state was prepared in this work. The microemulsion was formed due to the presence of a special system of surfactants, namely ethoxylated castor oil and fatty acid amides. Biological effect of suspension concentrate and microemulsion formulations of tebuconazole with the same concentration of active ingredient was investigated in the field experiments.
