Dear Growers,
After heavy rainfall of Tuesday (July 11th) in some parts of Illinois, we may experience substantial Phytophthora infection in cucurbit fields.
I recommend the following for the management of Phytophthora blight of pumpkins:
Spray plants at 7-day intervals with Orondis Opti + a copper alternated with Revus + a copper.
New label of premixed Odondis Opti can be found at the following link: http://www.syngenta-us.com/current-label/orondis-opti-premix.
If Orondis Opti is not available, consider the following:
Spray plants at 7-day intervals with Revus + a copper alternated with Ranman + a copper.
Plants should be sprayed immediately.
Regards,
