Abstrakt:	Neonicotinoid insecticides are used against the wide range of pests to protect plants. The influence of neonicotinoids on target and non-target insects is well understood. Hence, there are controversial opinions about the effect of neonicotinoids on the plants. We investigated pigments and photosynthetic primary reactions in two maize genotypes (the inbred line zppl 225 and hybrid zp 341) under thiamethoxam (TMX) treatment by root irrigation. It was found that the effect of TMX depended on pesticide application techniques and selection of maize genotype. TMX was added to the soil by root irrigation on the 4th and 8th days after planting, and photosynthetic characteristics monitored on the 10th and 12th days after planting. The primary photochemical reactions in PSII (Fv/Fm) of both maize genotypes were not affected under two variants of TMX treatment during all growing period. The hybrid zp341 was shown to be more susceptible to both TMX treatments, demonstrating a decrease in photosynthetic characteristics (JIP-test parameters) as well as changes in the content of pigments and in the conformation of the carotenoid molecule. Our findings suggest that the combination of fluorescence method and Raman spectroscopy is a perspective tool for monitoring plant state under pesticide application.
