One of the problems of potato growing is the contamination of plantings. If there are a large number of weeds, potato yields can decrease by 20-25% or more.
Weeds take moisture and nutrients from the soil, and as a result, potatoes may not receive enough nutrients needed for optimal growth and development. With a high degree of infestation, weeds can choke out potato plants at the seedling stage, which negatively affects photosynthesis and the formation of green mass of the plant and subsequently leads to large losses in the yield.
The branch of the Federal State Budgetary Institution "Rosselkhoztsentr" in the Krasnoyarsk Territory carries out work on monitoring, counting the number and determining the species composition of weeds.
In the Krasnoyarsk Territory, the most common types of weeds in potato plantings are field sow thistle, tenacious bedstraw, upturned acorn grass, white pigweed, field thistle, and creeping wheatgrass.
Based on surveys conducted by specialists from the branch of the Federal State Budgetary Institution "Rosselkhoztsentr" in the Krasnoyarsk Territory, agricultural producers receive a crop inspection report with a list of the most common weeds on the site. If the harmfulness threshold for contamination is exceeded, experts give recommendations on treating the area with herbicides, according to the list of pesticides and agrochemicals approved for use on the territory of the Russian Federation, if necessary, with the selection of the active ingredient of the drug.
Currently, one of the most effective methods of weed control is the use of chemical crop protection products (the use of herbicides). Proper selection of the active ingredient of the drug, together with compliance with the conditions and standards of use, can reduce the number and negative impact of weeds on potatoes, which has a positive effect on the quality and quantity of the crop.
The thoughtless use of herbicides, without taking into account the species composition of weeds and the competent selection of the active ingredients of pesticides, entails “empty” economic costs. Very often we hear from agricultural producers that their fields were treated against weeds, for example against bindweed, but there was no result. One of the main reasons for this is the incorrect selection of the active ingredient of the drug. Inspection of crops by specialists of the branch of the Federal State Budgetary Institution "Rosselkhoztsentr" in the Krasnoyarsk Territory makes it possible to determine the species composition of weeds in each area and select the most suitable herbicides for destroying or reducing the number of harmful objects.
