To conduct this Working according to these levels, saves your time, money and health. analysis, the pest infested area is scrutinized. Pest activity is observed by adopting patterns. 6. To monitor pests' density, sampling method is found to be effective. The sampling methods vary with the types of pests and crops. Net sweeping is the easiest way of sweeping in a row cropping, like at least 20 sweeps must be taken along a 20m row. Others are counting insects on plants' parts, attractant traps and Zig zag patterns are adopted for pests like aphids, as they are often uniformly distributed.
