Abstract
Two field investigations were conducted at the Ten Thousand Region, Behaira governorate, Egypt in 2022/23 and 2023/24 seasons to assess the impact of some insecticides against the white grub larvae on sugar beet plants as well as to estimate both yield and quality components. The experimental design was a randomized complete block design (RCBD) with three replicates and nine treatments including four organophosphate insecticides (Meritan® 10%GR, Mocap < sup>® 10% GR, Extra cap < sup>® 10%GR and Nema gold® 10%GR), two carbamate insecticides (Viva® 24% SL and Mesurol® 2% RB), entomopathogenic fungi (Care protector® 2% WP) and Egyperl as a carrier material, in addition to the untreated control. Results showed that Meritan® 10% GR achieved the highest reduction percentage of white grub larvae/ 10 plants during both seasons and equaled with Nema gold® 10%GR, Mocap < sup>® 10% GR and Extra cap < sup>® 10 %GR, followed by Viva® 24% SL without significant differences.On the other hand, Mesurol® 2% RB and Care protector® 2% WP produced the least reduction percentages followed by Egyperl, and untreated control treatment came in the final rank. The treatments, Meritan®10%GR, Mocap < sup>® 10%GR, and Extra cap < sup>® 10%GR demonstrated the best results regarding both yield and quality characteristics, while the lowest results were associated with Egyperl and Viva® 24% SL, which were less effective compared to the untreated control group.
