REMOVING NOXIOUS WEEDS A.PSEUDALHAGI FOR HIGHWAYS USING CHEMICAL MIXTURES

The removal of unwanted vegetation outside of agricultural land, such as roadsides and railways, is one of the main problems. Ensuring the safety and smooth operation of the transportation process in the railway and motor transport industry depends on the effectiveness of ways to protect the production infrastructure from vegetation. Currently, various herbicides of chemical compositions are used to control weeds. Unfortunately, so far, no herbicides have been found designed to completely destroy plants of this variety. In addition, despite the fact that highly effective herbicides are found, their high degree of toxicity harms representatives of the animal world. The growth of roadside grass, in addition to affecting the quality and safety of the work performed, worsens aesthetic perception and leads to swarming of livestock on verdant plants. This leads to emergencies that threaten the lives of animals. The effect of herbicides to a certain extent depends not only on plant species, but also on natural and climatic conditions, the degree of soil fertility. In regions with arid climates, for example, in the south of Kazakhstan, due to lack of moisture, there is a certain difficulty in destroying plants whose roots extend deep into the earth's crust. In this research work, as a result of experimental work, it was established that it is possible to destroy weeds with chemical mixtures.
