Abstract

A field study was conducted to determine influences of spray speed, liquid spray pressure, and height of boom sprayer on effective spray deposition and reduction of drift at canola (Brassica Rapa) flowering stage from AS 350 helicopter. Results of the study show that aircraft height of 2 m and liquid pressure 460  kPa at spray speed  97 km/h reduce effective drift when compared to boom height 10  m and low liquid pressure  230 kPa  for each other fly speed 138 km/h, 115 km/h under operating conditions. The result indicated that the amount of drift deposits decreased as target distance downwind increased. The minimum value of the drift at 50 m distance downwind no spray surface area  were 0.006 µg/cm2, 0.041 µg/cm2 and 0.064 for spray speed 97 km/h, 115 km/h and 138 km/h under operating pressure 460 kPa and aircraft height 2 m respectively. The maximum coverage value was 26.8 % at 460 kPa spray pressure compared to 14.7 % at 230 kPa under low spray speed and low aircraft height.
