Peanut Growers: Tropical Storm Bill

Posted June 16, 2015. The low pressure in the Gulf has turned into tropical storm Bill. It is now predicted to impact the coast further south than it was several days ago. Updated forecasts by NOAA indicate that the primary rains generated by the storm will go north of Mississippi (http://www.nhc.noaa.gov/refresh/graphics_at2+shtml/090804.shtml?rainqpf#contents).

You should still watch your weather maps for rain storms associated with this tropical storm.

Posted June 15, 2015. There is a low pressure forming north of the Yucatan Peninsula. It has an 80% chance of forming a tropical storm which is predicted to move northwest and hit the Texas/Louisiana border region.

If the storm does develop, we will almost assuredly receive spin-off storms. There is a chance some of these storms would carry spores of the peanut pathogens causing early leaf spot, late leaf spot and peanut rust.

I suggest you watch this storm (http://www.nhc.noaa.gov/). If it develops, apply a fungicide.

The fungicide is best applied prior to tropical storm generated rains, but a penetrant could be applied immediately after.

Possible fungicides are included in the 2014 list of labeled products https://www.mississippi-crops.com/2014/05/07/fungicides-labeled-for-use-on-peanuts-in-mississippi-2014/  .

A short list of products include: The (list does not include all possible labeled products, merely some common ones)

Before storm:

• Chlorothalonil – sold as Bravo, Chloronil, Echo, Equus;  Echo-Propimax or Tilt-Bravo, Muscle ADV .  Note: chlorothalonil is the sole or partial active ingredient in these products. It is in short supply and you may not find these products.

Before and After storm:

• Abound, Absolute, Fontelis, Headline, Priaxor, Provost, Stratego
