Safe Herbicide Development Based on Plant Raw Materials
The requirements for the safety of herbicides for humans, animals and the environment have increased due to the ecologization of agricultural production. The search for herbicides that have a less harmful effect on cultivated crops is carries out both among new classes of chemical compounds and among plants. There are few works in the papers on the development and application of plant origin herbicides, so this topic is relevant. In the present work, a new herbicide is proposed, obtained as a result of studies of the effects of extracts from 24 types of plant raw materials on the change in the biomass of weeds, both separately and in complexes. The developed preparation contains a complex of herbal extracts: chamomile, milk thistle, tansy, mustard blue (seed). With the help of classical methods of collecting plants, obtaining plant extracts and evaluating the raw biomass of weeds, a formulation was developed, laboratory and field tests of the herbicide were carried out. The drug has shown effective suppression of the weed vegetation growth in vacant lots and abandoned garden plots in the suburbs of Barnaul. The herbicide is recommended for soil processing between paths and rows of plants two or three times during the agricultural season.
