Analysis and estimate of efficiency technological methods the destruction of Sosnowsky hogweed in the north-west region of Russia

Abstract

The article explores a number of technological methods for the destruction of Sosnowsky hogweed (Heracleum sosnowskyi Manden) on agricultural lands. Graphical dependences of the degree of re-overgrowing by an invasive species of treated areas with working organs for its destruction were obtained. Based on the analysis of the obtained dependences, the most energy-efficient method of mechanical soil cultivation was revealed, which consists in high-quality pruning of the root system of weeds and the seeding of seeds with working bodies with a variable working width, which provides a significant decrease in the intensity of repeated overgrowing of the area with hogweed.
