Potential operator exposure to herbicides: a comparison between knapsack and CDA hand sprayers

Spray treatments with low volume CDA hand sprayers generally gave lower levels of operator contamination than high volume treatments with knapsack sprayers. The majority of contamination (80 - 90) occurs on the lower leg and feet irrespective of sprayer type. There is considerable scope to greatly reduce contamination with all sprayer types by changing spray practices and avoiding holding the spray lance in front of the operator. Use of a spray management valve (SMV) with the knapsack sprayer also reduced operator contamination.

Abstract

Spray treatments with low volume CDA hand sprayers generally gave lower levels of operator contamination than high volume treatments with knapsack sprayers. The majority of contamination (80 - 90) occurs on the lower leg and feet irrespective of sprayer type. There is considerable scope to greatly reduce contamination with all sprayer types by changing spray practices and avoiding holding the spray lance in front of the operator. Use of a spray management valve (SMV) with the knapsack sprayer also reduced operator contamination.
