The Ecological Formulation of a Pesticide Manufactured by JSC Schelkovo Agrohim (Russia) on the Example of the Herbicide Zontran CSC.

Abstract

The results of studying the effectiveness of the herbicide Zontran CSC, containing the active substance metribuzin 250 g/L in a preparative form (formulation) named colloidal solution concentrate (CSC) are presented. Experiments were carried out for two years in 2011-2012 on soybean crops with mixed type of weeds: annual dicotyledonous and annual grasses. The biological effectiveness of Zontran CSC was compared with a product containing metribuzin 700 g/kg in a formulation wettable powder (WP). It was established that the pre-emergence application of Zontran CSC on soybean crops at a dose rate of 1.2 L/ha was comparable to the biological effect of the product, consisting of metribuzin at 2.3 times more, but in the WP formulation. It was observed that Zontran CSC in comparison with the product containing a higher amount of metribuzin, but in the WP formulation, was at the level, and in some cases exceeded the biological effectiveness of this product. Thus, the formulation of the CSC allowed, without loss of biological effectiveness and with obtaining reliable yield increases, reducing the amount of metribuzin per unit of cultivated area, which makes the use of pesticide environmentally friendly, since it minimizes its release into the environment.
