| Abstract | ||||
| The study conducted during (2017-2018 and 2018-2019) at Plant Protection Farm, Faculty of Agriculture, Assuit University, Assuit, Egypt on tomato variety 765 planted on the 10th of September for each season in an approximate area (315 m2) in order to compare the efficiency of three Neonicotinoids [Thiamethoxam (Actara 25% WG), Imidacloprid (Best 25% WP ), Acetamiprid (Mospildate 20% SP)] in Nano and commercial formulation size using recommended dose for them and the half-recommended dose for nano-insecticides against tomato leaf miner, Liriomyza trifolii Burgess (Diptera: Agromyzidae). The randomized complete block design (RCBD) was applied with three replicates/ treatment and three control in a total of 21 plots. The replicate (plot) size was 3 ×3.5 m and consists of three rows planted with 5 plants/ row. The nano and commercial insecticide sizes showed highly significant results in reducing the infestations of mines in tomato during the studied seasons in the first and second week after (1st and 2nd) spray compared with control. The nano-thiamethoxam 1x was the best for mines reduction followed by nano–acetamiprid, and nano-imidacloprid. However, there were no significant differences between commercial and nano-formulations in mines reduction % and the highest reductions showed by nano treatments. However, the treated tomato by the half-recommended rate of nano and commercial formulations showed the same reduction results. | ||||
