Mainspring Compatibility with A. swirskii

Plants infested with 100 whitefly (25/plant) 3X on a weekly interval.

Predatory mites released 3X on a weekly interval (20/plant); with the first release occurring one week after first whitefly exposure and prior to Mainspring GNL (12 floz drench).

Overlapping stages of A. swirskii eggs and mobiles could be found 4 weeks after the last mite release indicating good compatibility with Mainspring GNL drench treatment.
