Control against the grey weevil in pistachio

Abstract

The article presents the results of studies conducted in 2023-2025 to evaluate the biological efficacy of insecticides against the grey weevil in pistachio (Pistacia vera L.) plantations under the climatic conditions of the Jizzakh region. The results showed that Mospilan 20% WP at application rates of 0.2-0.3 kg/ha and Pilarking 20% EC at 0.15-0.25 L/ha demonstrated high biological efficacy from the 7th day after treatment, reaching 99.4-99.5% by the 14th day. In the treatments with Atilla Super 10% EC at application rates of 0.2-0.4 L/ha and Decis 10% EC at 0.1-0.15 L/ha, high biological efficacy was observed as early as the 3rd day after treatment, with maximum efficacy reaching 99.0-99.5%. The obtained results demonstrate the high efficacy of these insecticides against the grey weevil and indicate their potential for use in integrated pest management programs for the protection of pistachio plantations under the climatic conditions of the Jizzakh region.
