Using of tank-type mixtures with herbicidal preparations for annihilation of non-desirable vegetation on objects of the Ministry of Defence of the Russian Federation

Abstract

The treatment of certain areas with tank mixtures of herbicides is a rational way of reducing costs of destruction of non-desirable vegetation at the facilities of the Ministry of Defence. The article is dedicated to the results of the evaluation of effectiveness of different modern herbicidal preparations and their tank mixtures during vegetative laboratory tests and field experiment. Monocotyledonous plants (pooideae including wheat), dicotyledon plants (legumes including kidney beans), sunflower family (including sunflower itself ) and cruciferous plants (radishes) have been tested. These families include most of the weeds, infesting non-agricultural lands. The doses of individual drugs that cause 50% and 70 % mortality of plants were determined by the method of probit analysis. The efficiency of tank mixtures was evaluated by the value of the coefficient of synergistic action. If the actual effects of tank mixture exceeds the expected, the presence of synergistic interaction of active substances and the effectiveness of tank mixtures considered to be established (preparations Goliaf+ Shkval for sunflower and pooideae; preparations Goliaf+Lintur for cruciferous plants). Otherwise, the combination of preparations was considered ineffective due to the antagonism of the active substances. The results of comparative experiments showed, that it is feasible to use a tank-type mixtures, containing herbicidal preparations Lintur+Goliaf+Shkval+Atron for the control or complete annihilation of non-desirable vegetation at military facilities
