Application of growth regulators in field mint cultivation technology – a guarantee of obtaining ecologically clean products

Field mint is a common perennial medicinal plant. Its green mass is widely used in the food, perfume and pharmaceutical industries. One of the reasons for the decrease in green mass production is the high infestation of crops. The key to successful weed control is taking into account the diverse interactions between cultivated and weed plants. The study of these phenomena makes it possible to make maximum use of cultivated plants to suppress weeds. By using various methods of cultivating agricultural crops, it is possible to ensure the effectiveness of natural weed suppression. The objective of the study was to assess the possibility of using growth regulators in mint cultivation technology, to determine critical periods, and the harmfulness of the weed component of the mint cenosis in the forest-steppe zone of the Chechen Republic. The location of the study is the Gudermes district of the Chechen Republic; the period is 2022-2023; the object is the Rozovskaya Aroma mint variety. The possibility of using Humate + 7 0.01% as a growth regulator (GR), which was used to treat mint seeds before sowing, was studied. Based on the results of model field experiments in the forest-steppe zone of the Chechen Republic, a mixed type of weed infestation of field mint was established. With an increase in the number of cenosis components, there is a decrease in the yield of field mint. Crop losses are more than 60% at maximum weed infestation. Growth regulators ensured a decrease in crop losses. The critical period of weed harmfulness is the first 30 days from the moment of emergence. When using growth regulators, the critical period of harmfulness of the weed component was 23 days.
