Deposit assessment of Bacillus thuringiensis formulations applied from an aircraft.
Deposit assessment after aerial spraying with Bacillus thuringiensis (B.t.) formulations consists of the analysis of the splash of droplets on Kromekote papers and determining the number of bacterial colonies growing on nutrient agar medium Petri dishes. However, neither of these two methods provides a number of spores deposited although this figure is essential to determine treatment efficiency. Both methods are evaluated with regard to this need and a new approach is suggested.
