The effect of a new multicomponent herbicide based on phenylcarbamates on sugar beet plants

The use of chemical herbicides to control weeds is part of the growing process for most major crops. However, if applied regularly, they can lead to contamination of soil and groundwater, as well as accumulation of residues in crops and the emergence of resistant weed populations. In this regard, it is important to develop environmentally friendly chemical herbicides with new mechanisms of action. Natural phytotoxins of plant or microbial origin can serve as prototypes of active substances. The article discusses the following aspects: 1) the relevance of the topic of the impact of herbicides on the environment and their phytotoxicity; 2) information on the compositions of herbicides and their impact on the environment; 3) technology for the production of multicomponent herbicides and its improvement; 4) experimental determination of the effectiveness of the herbicide being developed. The work examines three types of herbicides: Bifor 22 (taken as a reference), Crucifer, and a new experimental herbicide. Test samples of beets and weeds were treated with the studied herbicides, 3 samples each. Then the chlorophyll content in each of the samples was determined, taking into account the ratio of shoot masses, humidity and the dry mass ratio of the test samples. The chlorophyll content is minimal in samples treated with crucifer - about 7 rel. units, but maximum in samples treated with the developed herbicide - 10 rel. units. The obtained high value of such an indicator as the chlorophyll content confirms the safety of using the developed herbicide in agriculture. Based on the results of the experiments, the positive effect of using the new developed multicomponent herbicide was proven and the prospects for its use were determined.
