Factors Affect Efficacy of Systematic Insecticides

Cloyd, R. Greenhouse Management and Production 28 (11):44, 46-48. 2008.

Systemic insecticides available for use in greenhouses and labeled for drench applications include: neonicotinoid-based insecticides imidacloprid (Marathan), thiamethoxam (Flagship), dinotefuran (Safari), and clothianidin ( Celero); and the organophosphate insecticide, acephate (Orthene/Precise). The uptake, movement, distribution and accumulation of systemic insecticide active ingredients in plant tissue may be influenced by water solubility and two physical estimated properties: acid dissociation constant (pKa) and octanol-water partition coefficient (log poet).
