Species composition and features of weed control on irrigated lands in the system of forest strips

Abstract

Under irrigation conditions, weeds reduce agricultural production. On irrigated lands in the conditions of the Volga region in the system of forest strips, weeds grow faster. The measures applied in the fight against weeds, depending on the species composition, are primarily an obstacle to their penetration into the fields and measures that are used in the fight against weeds in the irrigated field. In agricultural production, when irrigation is carried out in the system of forest strips, weed control must be carried out taking into account the species composition of weeds that determine the type of contamination and the economic threshold of harmfulness. Agrotechnical weed control measures have the maximum effect in the weed control system, primarily in combination with chemical protection of crops from weeds.
