Integrated wireworm protection system for potato plantings

The results of growing varieties of medium-ripened potatoes in light chestnut soil on drip irrigation are presented. Promising options have been identified that contribute to the formation of high yields of the studied crop.

Introduction. Etching potato tubers is one of the most effective methods of controlling some potato pests and diseases. The primary problem before modern farmers is the wire that is harmful to potato plantings. Wire worms, which live in the soil of the larvae of nutcracker beetles, are a serious threat to global agricultural production.

Object. Vineta variety potatoes.

Materials and methods. For a number of years, scientists from farmers of the Caspian Agricultural Federal Scientific Center of the Russian Academy of Sciences have been doing a lot of work to identify and eliminate the consequences of potato planting by a wire. Studies were carried out at the irrigated land use site of the Federal State Budgetary Institution "PAFNC RAS" in the period from 2021 to 2023. In the experience, generally accepted agricultural equipment was used in accordance with zonal recommendations for the Lower Volga region when cultivating early potatoes. Appropriate studies and measurements were performed in accordance with the requirements of the field experience method and the methods of studies on potato culture. In the course of the work, an optimized system for protecting potato plantings is proposed and parameters for the economic effectiveness of protective measures are given. In the course of research, the effect of newgeneration drugs Klubneshchit, Prestige, CS and Metarizin on the number of wireworm was assessed.

Results and conclusions. On average, when analyzing Vineta early potato tubers, it was found that the samples presented were mainly with weak and medium damage to 1-2 holes as a result of the use of this plant protection scheme. The results of economic efficiency made it possible to identify a highly profitable option with an irrigation rate of 5200 m3/ha and with additional sediment treatment with Klubneshchit, the CS which showed very high indicators of commercial yield of 59.1 t/ha. Net income per 1 ha amounted to 1033.1 thousand rubles/ha. The profitability indicator at such values was at the level of 232.5%.
