Abstract
A detailed analysis of methods for diminishing the negative effects of weeds on the agricultural plants as well as for quantity reduction of weeds on the non-cultivated lands has been made. The results of three-year estimation of phytosanitary state of lands have been given, the expedience of agronomic techniques and of the use of herbicides on the abandoned lands which were not cultivated for many years has been substantiated. The phytosanitary state of fields has estimated by the method of fields examining on their weed infestation. Herewith, the rate of weed infestation, the species and qualitative compositions of weeds, their life-forms have been estimated. Besides, seed supply recordings as well as the recordings of organs of weeds’ vegetative propagation in soil have been made. The germination rate and other peculiarities of weeds behavior both in agrocoenosis and on the abandoned lands have been studied. It has been made a forecast as for the feasibility of reusing of these lands for growing of the agricultural produce on the basis of development and introduction of ecological approaches as well as of economically justified methods on diminishing the real and the potential weed infestation in agrocoenosis. The effects of complex herbicides on weed infestation of 0-40cm soil layer with vegetative organs of weeds on the abandoned lands have been elucidated. It has been proved that three-year use of herbicides promotes to quantity reduction of organs of vegetative propagation of weeds within 81.3-94.5% as compared to initial weed infestation. It has been determined that systematic use of herbicides like Diplodoc, w. s. and Raundap w. s. during three years of studies results in reducing of weeds infestation with organs of vegetative propagation of perennial weeds sorts as well as in receiving a maximal protective effect. To receive a maximal effect, the herbicides should be used annually.
