- Abstract
The utmost essential and vital textile fiber throughout the world is Cotton (Gossypium hirsutum L.) that accounts in the world's total fiber production over 40%. Despite the fact that around the world about 80 countries produce cotton in which Pakistan is one of the ancient homes of cultivated cotton. Cotton is considered as "white gold" for Pakistan. Present research was conducted at Entomological Research Institute, Ayub Agricultural Research Institute, Faisalabad during 2018-19. A comparative evaluation of effect of tractor mounted boom spraying on droplet density and bio-efficacy were observed and comparison was made between different sprayers i.e. tractor mounted boom sprayer (TMB), battery operated knapsack sprayer (BOK), hand operated knapsack sprayer (HOP), power operated knapsack sprayer against whitefly on cotton crop. It was found that on an average droplet density by TMB sprayer was significantly high (p=0.00) 296, 256 and 244 droplets cm-2 by HOK, BOK and POK at top, middle and bottom, respectively. On an average bio-efficacy of tractor mounted boom sprayer was more (88.15, 84.47 and 55%) after 3, 7 and 15 days of spray, respectively than other three sprayers viz. HOK, BOK and POK. Tractor mounted boom and bio-efficacy was found efficient as compared to the other spraying techniques.
