บทคัดย่อ (EN): Prophylactic ground spraying of copper oxychloride in agriculture spray oil using mist blowers is a general practice to manage abnormal leaf fall (ALF) disease caused by Phytophthora spp. However, this practice has become less attractive due to paucity of labour. In view of this, various alternative ground spraying systems were attempted. In the present study, the blower assembly of the conventional mist blower was attached to a mini tractor. The power for operating the sprayer was provided by the power take off (PTO) shaft of the tractor. Field studies revealed no significant difference with respect to leaf retention between the conventional mist blower and the tractor mounted mist blower. Therefore, the conventional atomizer was replaced with a modified one and field tested. The delivery height obtained with the new system was comparatively higher. However, certain defects like slip of propeller shaft while moving in the uneven terrain and power output incompatibility between tractor and mist blower were noticed in the system during field operations due to which the expected discharge height was not attained. In order to overcome the defects, the spraying attachment was connected directly to the PTO shaft of the tractor using a single wheeled gear box assembly and a blower assembly having 12hp capacity. The modified system was field tested again and a delivery height of 26.8 m was obtained. The new system resulted in leaf retention of 50% while the conventional mist blower gave only 30% on the most susceptible clone RRIM 600. The improved mini tractor mounted mist blower was found very effective for plant protection operations in rubber plantations of India, due to its less labour requirement and more area covered per unit time.
