• An extract of Chenopodium ambrosioides near ambrosioides.

• Contains a variety of terpene compounds• Formerly referred to as Facin, Keynote, QRD

400 and QRD 416• Displays signif icant activity on soft bodied

insects

• 2006 field testing focused on finding activity– Only greenhouse testing had been done prior to this

• 2007 trials emphasized– rate finding – exploration of non-core crop/pest complexes

• 2008 field program emphasized– Continued rate finding– Tank-mix and rotational programs

• Small plots and limited large-scale testing.

– Continued exploration of non-core crop/pest complexes



• Core crops– Tomatoes– Peppers– Cucurbits– Onions

• Core pests– Thrips– Whiteflies– Aphids– Web spinning mites


• Requiem’s mode of action:– Degrades the exocuticle of soft-bodied insects– Destroys the tracheal lining of same via localized

Requiem™ 25EC Insecti cide/miticide

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
