Organic Options for Colorado Potato Beetle Control (please consult your certifying party to determine if these products are allowed first before using)
Entrust Naturalyte
Insect Control

generations of Colorado potato beetle and do not make more than
two applications per single generation of Colorado potato beetle.

UN
UN
2-16 oz
15-30 oz
Most effective on small larvae, initiate application when 25% of the initial egg masses have hatched or more than 200 small larvae are found on 25 vines, continue to scout and apply at 5 to 7 day intervals during egg hatching. Allowed for organic production if allowed by sanctioning body
Azera(azadirachtin plus pyrethrins)

Reapply every 7-14 days as necessary to maintain control during periods when larvae are present but during periods of heavy infestation and extended egg hatch, reapply every 4-5 days. Do not use spreading agents, especially silicone-based spreaders.
