Abstract:
The field experiment was conducted at Entomology farm, Department of Entomology, BACA, AAU, Anand during summer, 2021 to determine the bio-efficacy of different acaricides against two spotted spider mite, Tetranychus urticae by using Randomized Block Design (RBD) with three replications and the results revealed that the lowest (3.00 mites/1 cm2 leaf area) population of mite were found in plots treated with spiromesifen 22.9 SC @ 0.02% and it was at par with abamectin 1.9 EC @ 0.00057% (3.19 mites/1 cm2 leaf area) and fenazaquin 10 EC @ 0.012% (3.34 mites/1 cm2 leaf area). The highest fruit yield was recorded from the plot treated with spiromesifen 22.9 SC @ 0.02% (8574 kg/ha) and it was at par with abamectin 1.9 EC @ 0.00057% (8558 kg/ha) and fenazaquin 10 EC @ 0.012% (8541 kg/ha) as compared to the rest of treatments.
