abstract
The experiment was conducted against leaf miner, Liriomyza trifolii infesting cucumber for the two consecutive year (2015-16 and 2016-17) at Agronomy Farm, BACA, AAU, Anand-388 110, Gujarat, India. The objective of the experiment was to evaluate bio-efficacy of different insecticides including seed treatment molecules. The experimental plot area was replicated thrice and ten treatments with randomized block design. The experimental results revealed that among the different insecticides evaluated significant lower number of mines and leaf damage were recorded in seed treatment with Thiamethoxam 35 FS + Thiamethoxam 25 WG (2.25/leaf; 9.93 %) followed by seed treatment with Imidacloprid 600 FS + Thiamethoxam 25 WG (2.42/leaf; 11.65%) and Thiamethoxam 25 WG (2.53/leaf; 12.96 %), respectively. The data on fruit yield of cucumber indicated that significant maximum cucumber fruit yield (112.01 q/ha) was recorded from the plot treated seed treatment with Thiamethoxam 35 FS + Thiamethoxam 25 WG. The next best effective treatments were Imidacloprid 600 FS + Thiamethoxam 25 WG (102.35 q/ha)] and Thiamethoxam 50 WG (88.35 q/ha) which were remained at par with each other.
