NEW INSECTICIDE SHOWING GOOD ACTIVITY ON WHITEFLY ADULTS

A newly registered insecticide, PQZ, from Nichino America has shown good efficacy against the adult stage of silverleaf whitefly in multiple small plot tests in the last few weeks. While overall efficacy has not been fully evaluated, the activity on adults has appeared equal to Sivanto, which has been considered our best product on adults of this species. This product also provides a different mode of action as compared to most of the products we use against whitefly.While PQZ may not be a standalone product for whitefly, with good activity against adults, likely moderate activity (possibly better) on immatures, and a different mode of action, PQZ should be considered in insecticide rotations for this pest.
