Proper spraying with appropriate efficacy has been major concern in chemical application
due to growing concerns about environmental and health hazards associated with chemical
pesticide application. Most of the spraying system developed in India spray from top of the
plant resulting in poor spray penetration in crop canopy and overall low efficacy of spraying
operation. A five-nozzle boom system was developed considering the canopy requirement
of tall crops such as cotton and pigeonpea. Laboratory evaluation of the system indicated
that HCN 80250 hydraulic nozzle in combination with 125 mm air sleeve gives a proper
droplet size distribution to get more than 90% droplets within 300 micron range and about
13-16% percentage area covered on front and back of leaves in entire canopy. A power
tiller operated spraying system consisting of similar boom and air assistance system was
developed and evaluated under field condition. The effective field capacity was 0.146 ha/h
in pigeon pea crop at forward speed of 1.31 km/h. The percentage area covered by the
droplets on the front and back side of the leaves was almost equal viz. 17.5-18%. The
mean droplet size varied from 120 to 124 microns with more than 90% droplets was less
than 300-micron size.
