Abstract
The experiment was carried out in Shandaweel Agricultural Research Station, Sohag Governorate, in two successive seasons of 2022 and 2023 to study the effect of seed treatment of three sorghum genotypes with some insecticides, i.e., Trigard, Gaucho, Match, and Fortenza on S. frugiperda infestation after 14, 21, 28, and 35  days after emergence (DAE). The results showed that fortenza treatment recorded the lowest mean number of infested plants. However, the control recorded the highest mean number of infested plants. Dorado variety was the most infested genotype by S. frugiperda followed significantly by Shandaweel-1 hybrid in both seasons. The data showed significant differences between seasons for plant height and pests. Also, highly significant differences were found between seed treatments and among genotypes for all the studied traits. The first shortest period till days to 50 % flowering was obtained by application of Fortenza to the sorghum genotypes under study. Untreated  seed (control) shortens plant height significantly. Sorghum genotype H-306 surpassed the other sorghum genotypes under study in plant height (195.00 and 198.33 cm) in 2022 and 2023 seasons respectively, with significantly affect. Untreated seeds (control) reduce the 1000 grain weight significantly. H-306 recorded the least loss of yield compared with the other genotypes. No. of Pests /Plant had negative and highly significant correlation with plant height, 1000-grain weight and grain yield/plant. But, No. of Pests /Plant had positive and highly significant correlation with Days to 50% flowering.
