Abstract:

Pesticide application is a complex process and the magnitude and uniformity of spray deposition is mainly influenced by target canopy characteristics, type of spray equipment and mode of operation and properties of spray chemicals. In the present context, application of pesticides from top of the plant results in poor penetration of the pesticide to desired locations where insects lay their eggs or hide in other stages of their growth. Considering the above factors into account, a bullock drawn air assisted Intra canopy sprayer was developed at the College of Agricultural Engineering, Raichur. The developed sprayer was tested in the research farm for spraying on cotton crop using a pair of bullock (Breed: Khillari) under physiological limits of bullocks with visual fatigue symptoms. The average field capacity of intra canopy sprayer was found to be 0.80 ha h-1. The swath width of spray was found as 3260 mm. The increased height of boom from 15 to 45 cm caused the higher swath width of spray. The cost of operation worked out for bullock drawn air assisted Intra canopy sprayer for spraying on cotton crop was Rs. 540.50 ha-1. The saving in time and cost for spraying on cotton crop using bullock drawn intra canopy sprayer was found to be 88.43 % and 82.24 % respectively.
