The problem of rice damage by “black spotting” in the field during maturation is acute in all rice-growing countries. In the work, it was necessary to study the spread of shield bugs on rice crops in the Krasnodar region, the intensity of damage to rice crops in various areas according to the method of assessing damage to the rice crop, differentiation of varieties by tolerance to damage. Surveys of rice crops were carried out during various periods of the growing season in order to identify insect pests with piercing-sucking mouthparts in the Krasnoarmeysky, Abinsky, Slavyansky, Kalininsky districts of Krasnodar region and Prikubansky district of Krasnodar in 2020-2023 and a comparative assessment of the intensity of damage to rice grains in the form of dark spots by region is given. The highest intensity of grain damage was noted in Krasnoarmeysky district. Preliminary results on the tolerance of varieties to grain damage by stink bugs during the rice growing season were obtained and preliminary differentiation of varieties was carried out. The most tolerant varieties were Abinsky, Vector, and Strombus, and therefore these varieties are recommended to be grown in areas with the most intense damage to crops by stink bugs. Methodological methods have been developed for studying the “black spotting” of rice, which consist of selecting samples of rice varieties in industrial crops in areas of its cultivation, characterizing the content of damaged grains and assessing the influence of the intensity of damage on the physical properties of the yield. |
