PAW Program Objectives
Soil preplant treatment for pest control is important to achieve high quality yields in a wide range of agricultural crops, from strawberries and cut flowers, to fruit and nut tree crops. Preplant soil preparation is also vital to successful nursery operations, from forest trees to sweet potatoes. Methyl bromide (MB) fumigation was the primary method of achieving this preplant pest control. Though effective and inexpensive, the damaging effect of MB on the ozone layer and worker safety issues prompted the phase-out of its use, and stimulated research in alternative methods of preplant pest management.
