Peanut Rust Showing Up – Late as Usual

Peanut rust is a late season problem that we see in most years in isolated areas. This year it may be worse than normal. I saw some this week and I talked to several others who have seen it. Crop Advisor Luke Johnson said a grower called saying he thought he had burned his peanuts with a spray but it turned out to be peanut rust. UGA Plant pathologists report that it is showing up across Georgia.  I’ve seen it be a problem where fungicides were used that don’t have much activity on it without cholorothalonil added in.

 

I have several photos here I took this week of the disease.
