Peanut Leaf Spot Advisories for Aug 24


Tropical storms can pose a triple threat to disease control: conditions that are highly favorable for disease, potential loss of fungicide activity, and fields too wet to spray. Leaf spots, particularly late leaf spot, Rhizoctonia limb rot, web blotch, and Botrytis can really take off following heavy fall rains.

Under normal conditions, we expect foliar fungicide protection to last 10 -14 days, but heavy rains can lead to some wash-off and shorten the protection period. Headline probably is our longest-lasting foliar fungicide and will give excellent protection against late leaf spot and web blotch at 9 -12 oz/a. If you feel you need additional protection against stem rot, consider adding 13-16 oz Convoy to a Headline spray since Convoy is also long-lasting. Keep in mind that Convoy has a PHI of 40 days, however. Provost at 8-10 oz/a is active against leaf spots and stem rot and can provide the needed protection. Abound at 12-18 oz/acre would be a good choice for fields at risk for Rhizoctonia limb rot based on history and/or heavy vine growth. Avoid using tebuconazole since it is very weak against late leaf spot and vulnerable to wash-off.
