Leafminer Literature & Efficacy Summary – 2018

Research Summary Abstract

From 2009 to 2015, numerous products representing 15 active ingredients were evaluated in the greenhouse to control dipteran leafminers (Liriomyza trifolii and other species). Nine trials were conducted on chrysanthemum, daisies and daylily. Depending upon product characteristics either foliar, drench or topdress applications were made. Although there were insufficient data for definitive conclusions, 2 relatively new products may be effective management tools: Arena provided good efficacy for Liriomyza spp., and Mainspring provided good efficacy for both Liriomyza trifolii and Ophiomyia kwansonis. The established standards Avid and Terraguard generally provided variable efficacy.
