cyantraniliprole (Exirel)

Exirel has some contact activity but is most effective when ingested. Rapid anti-feeding activity. Insects typically die within 1-3 days of feeding. Soft on many beneficial predatory insects. It is translaminar and foliar systemic (moves to new leaves). For best results, use with an adjuvant (MSO). The spray solution should be pH 8 or less. Make only two consecutive applications of Group 28 insecticides (e.g., Exirel, Vantacor, Voliam Flexi) before rotating to an insecticide with a different MOA.

Material Type: Insecticides and Repellents

Formulation: Liquid
EPA Number: 279-9615

Usage for cyantraniliprole on Potatoes

Max Application per Season: 61.8fl oz

Emergence to Row Closure

Target Application per Acre REI PHI MOA Eff. Notes
Aphid 13.5-20.5 fl oz 12 h 7 d 28 G Apply before aphid populations build. Rapid anti-feeding activity helps to limit spread of viruses, like Potato Virus Y, that spread quickly.
Armyworms, Cutworms, Loopers See Label 12 h 7 d 28 E Apply when caterpillars are small.
Colorado Potato Beetle 5-15.5 fl oz 12 h 7 d 28 E Apply at 50% egg hatch when larvae are small. Do not apply more than once via chemigation for CPBs.
Potato Psyllid 13.5-20.5 fl oz 12 h 7 d 28 E (a) Apply before psyllid populations build. Target the adult life stage. Rapid anti-feeding activity will also help to limit spread of zebra chip disease.

Tuber Bulking

Target Application per Acre REI PHI MOA Eff. Notes
Aphid 13.5-20.5 fl oz 12 h 7 d 28 G Apply before aphid populations build. Rapid anti-feeding activity helps to limit spread of viruses, like Potato Virus Y, that spread quickly.
Armyworms, Cutworms, Loopers See Label 12 h 7 d 28 E Apply when caterpillars are small.
Colorado Potato Beetle 5-15.5 fl oz 12 h 7 d 28 E Apply at 50% egg hatch when larvae are small. Do not apply more than once via chemigation for CPBs.
Potato Psyllid 13.5-20.5 fl oz 12 h 7 d 28 E (a) Apply before psyllid populations build. Target the adult life stage. Rapid anti-feeding activity will also help to limit spread of zebra chip disease.

Late Tuber Bulking to Harvest

Target Application per Acre REI PHI MOA Eff. Notes
Aphid 13.5-20.5 fl oz 12 h 7 d 28 G Apply before aphid populations build. Rapid anti-feeding activity helps to limit spread of viruses, like Potato Virus Y, that spread quickly.
Colorado Potato Beetle 5-15.5 fl oz 12 h 7 d 28 E Apply at 50% egg hatch when larvae are small. Do not apply more than once via chemigation for CPBs.
Potato Psyllid 13.5-20.5 fl oz 12 h 7 d 28 E (a) Apply before psyllid populations build. Target the adult life stage. Rapid anti-feeding activity will also help to limit spread of zebra chip disease.
Tuberworm 7-13.5 fl oz 12 h 7 d 28 E Target PTW larvae feeding in the canopy in the weeks prior to vine desiccation or harvest. PHI is 7-days. For best results, chemigate in 0.1-to-0.2-acre inches of water and add MSO at 12 to 16 fl. oz per acre. Foliar sprays may not provide adequate control of larvae in the mid to lower canopy.
