Testimonials

Amy Morris
Head Grower
NG Heimos Greenhouse

“We trialed Mainspring® GNL insecticide and found that a drench provided excellent coverage. We were not seeing any caterpillars, thrips, aphids or leafminers. If we want 100% coverage, we drench with Mainspring GNL. With our outdoor mums, we used to have to spray every week just to prevent flare ups of aphids or caterpillars. We’re able to eliminate a lot of that product use. We drenched our poinsettias 8 weeks prior to shipping using the 10 oz. rate and found that it held perfectly. I was very happy with the results of Mainspring GNL.”

“Mainspring GNL was very effective for controlling whitefly on our poinsettia crops. We appreciate that Mainspring GNL gives you the option to drench and provides at least 6-8 weeks of control; it is a great preventive treatment. In our operation we use a lot of beneficial insects and Mainspring GNL did not have a negative impact on them. I would recommend it to other growers and will continue using it in my greenhouse.”

“All our hanging baskets are treated with Mainspring GNL about three weeks after transplant. This has provided very effective aphid control. We spray weekly with beneficial nematodes for fungus gnats and thrips control and the Mainspring GNL drench works well with this practice. I am so pleased with the efficacy of Mainspring GNL that I plan on using it on our next poinsettia crop in conjunction with biologicals for whitefly control. I appreciate the low restricted-entry interval and the ability to incorporate this chemical into my IPM strategy.”

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.
