• Insecticide were applied on 30 Jan and 13 Feb 2012. • Foliar sprays applied using a Lee Spider Spray Trac tractor

with a spray boom that included three TJ-60 11003VS nozzles per bed, covering four beds (twelve nozzles on the boom) applying 50.6 gpa at 25 psi.

• Alate aphids and apterous aphids were counted on ten random plants in each plot on each sampling date

• There were two aphid species present; initially only GPA, Myzus persicae and later CA, Brevicoryne brassicae colonies were detected in low numbers.

GF-2860 is spinetoram and sulfoxaflor


Exirel and Verimark (a.i. cyantraniliprole)

• Exirel & Verimark are diamide insecticides IRAC Group 28 ryanodine receptor modulators nerve and muscle action.

• What are the benefits? – My experience with Exirel & Verimark :

• I don’t have personal experience with cyantraniliprole as an aphicide. • I have found cyantraniliprole to be more active against sweetpotato

whitefly biotype B than other diamides. • Cyantraniliprole is very efficacious for control of sweetpotato whitefly

biotype B; as efficacious as most industry standards • Exirel & Verimark will be useful for IRM. • Diamides, including cyantraniliprole, are highly efficacious for control of

lepidopterous worm pests. • Diamides are safer for beneficial arthropods than older broad spectrum

chemistries; e.g., organophosphates, carbamates and pyrethroids.


Sequoia (a.i. sulfoxaflor)

• Sequoia is a IRAC Group 3C nicotinic acetylcholine receptor (nAChR) agonist nerve poison.

• What are the benefits? – My experience with Sequoia (Closer) a.i. sulfoxaflor:

• Sequoia is a good aphicide with efficacy comparable to an industry standard, Movento.

• Sequoia is useful in IRM, preventing aphid insecticide resistance. • I found Sequoia to be slow acting against tomato psylid, but may

be an efficacious alternative that should help with IRM • Sequoia may not be as efficacious as some industry standards for

control of sweetpotato whitefly biotype B but it is useful for IRM. • Safer for beneficial arthropods than older broad spectrum

chemistries; e.g., organophosphates, carbamates and pyrethroids. Mention of any pesticide in this presentation is not a recommendation.

Sivanto (a. i. flupyradifurone)

• Sivanto 200SL is a butenolide; IRAC Group 3D a nAChR agonist nerve poison.

• What are the benefits? – My experience with Sivanto 200SL :

• Sivanto is a good aphicide with efficacy comparable to an industry standard, Movento.

• Sivanto is another aphicide that will be useful for IRM. • I found Sivanto to be slow acting against tomato psylid, but may be

an efficacious alternative that should help with IRM • Sivanto is as efficacious as some industry standards for control of

sweetpotato whitefly biotype B and will be useful for IRM. • Safer for beneficial arthropods than older broad spectrum

chemistries; e.g., organophosphates, carbamates and pyrethroids.


(a. i. pyrifluquinazon)

• The mode of activity of a.i. pyrifluquinazon remains unknown; IRAC Group UN a nAChR agonist nerve poison.

• What are the benefits? – My experience with a.i. pyrifluquinazon:

• I don’t have direct experience with pyrifluquinazon for aphid control, but I’ve seen where is was less efficacious than an industry standard, Movento.

• Pyrifluquinazon is as efficacious as some other industry standards for control of sweetpotato whitefly biotype B and will be is useful for IRM.

• Pyrifluquinazon looks promising for reducing the transmission for certain whitefly transmitted plant viruses; e.g., CYSDV.

• Safer for beneficial arthropods than older broad spectrum chemistries; e.g., organophosphates, carbamates and pyrethroids.
