Mainspring GNL Insecticide Learning Module

Using Mainspring GNL in Outdoor Production

Mainspring can be used in:

• Perennial crops:
  • Apply preventively as a foliar spray when pest pressure from leaf-feeding beetles, aphids, thrips, caterpillars, etc., is starting. This will prevent pest populations from building to damaging levels.
  • Apply as a drench to hanging baskets once plants are rooted in (2 - 3 weeks after transplanting liners) or before plants are suspended in greenhouse.
  • Drench applications should be made once plants are well rooted. Drench applications will provide longer residual control across the pest spectrum.
• Woody Ornamentals (shrubs/trees):
  • Begin foliar applications on two-week intervals as pest pressure is starting to control leaf-feeding beetles, lacebugs, aphids, thrips, lepidopteran pests, etc.
  • Use systemic soil treatments for season-long protection from difficult to control pests such as soft scales, adelgids, plant bugs, psyllids, leafminers, leaf-feeding beetles.
