Questions with Nancy Rechcigl

What is Mainspring GNL insecticide?

Mainspring^® GNL insecticide is a powerful resistance management tool in IRAC Group 28 that systemically moves throughout the plant to control key chewing and sucking pests such as:

• Thrips
• Whiteflies
• Aphids
• Caterpillars
• Leafminers
• Leaf-feeding beetles
• Soft scales
• Lace bugs

The active ingredient, cyantraniliprole, makes Mainspring GNL a neonicotinoid alternative that is suitable for use in various integrated pest management programs because of its compatibility with many biological control agents.

How does Mainspring GNL work?

Mainspring GNL stops insect feeding shortly after ingestion, which limits damage to the plant and disease transmission, leading to insect mortality in two to seven days.

When sprayed, Mainspring GNL has translaminar and locally systemic activity. The active ingredient penetrates the plant cuticle to form a reservoir within the plant tissue. When drenched, Mainspring GNL is taken up by the roots and moves upward in the xylem throughout the plant canopy.

Where and how can Mainspring GNL be applied?

A very flexible product for growers, Mainspring GNL is labelled for use in greenhouses and nurseries and can be applied as a spray, drench and soil treatment.

• As a foliar spray, the recommended use rate is 4 to 8 fl. oz./100 gallons of water for 14 to 21 days of control.
• For drench applications to containerized plants, growers should follow the recommended use rate of 8 to 12 fl. oz./100 gallons of water for 8 to 10 weeks of protection.
• For in-ground grown and larger plants, apply as a soil treatment using rates of 0.125 to 0.25 fl. oz. per foot of height or per inch of trunk diameter at breast height (DBH). Mix product in enough water to treat an area 1-3 feet from the base of the trunk that will penetrate the root zone. Apply solution uniformly to the soil around the base of the plant.

Are there other benefits to using Mainspring GNL?

A significant benefit for growers is the improved worker safety with the use of Mainspring GNL when compared to pyrethroids, organophosphates and carbamates. Additionally, Mainspring GNL features a four-hour REI, making it less disruptive to daily work schedules.

Mainspring GNL also improves greenhouse and nursery efficiencies. With its extended residual, broad-spectrum control and systemic activity, Mainspring GNL helps save time and labor on repeat applications.

Mainspring GNL is also available in two Multipaks to give the grower added value, the Mural^® fungicide + Mainspring GNL Multipak or the Avid^® 0.15 EC miticide/insecticide + Mainspring GNL Multipak. Save up to 20% by purchasing either of these Multipaks instead of buying each product separately.
