Requiem™ 25EC insecticide/miticideConclusions
• Requiem exhibits good activity on its targets• 2 qts/acre is the X rate
– No consistent rate response beyond 2 qts/acre within the core pest/crop complex
• Surfactants have little to no effect (beneficial or detrimental) on performance
• Work to expand the crop/pest complexes continues
• Expecting EPA registration in 4Q2008
