Peanut Weeds – Sicklepod

Posted by romeethredge on July 3, 2014

Weed controls are going out in a big way right now. We are putting out our final herbicides, hopefully.  Some pigweed are having to be hand pulled. They grow extremely fast and if they get by our herbicides then we have to pull them. Also morninglories  and coffeeweeds are doing well.

Here is some info on coffeeweed control by Dr. Eric Prostko, UGA Extension scientist.

“Over the past 2 years, peanut growers in Georgia have experienced more problems with sicklepod (a.k.a. coffeeweed). Sicklepod can be very troublesome to control in peanut for several reasons including the following: 1) sicklepod plants produce a large number of seeds (25,000 seeds/plant); 2) sicklepod seed can remain viable in the soil for at least 5 years; and 3) none of the residual herbicides labeled for use in peanut provide adequate control.

Growers who continue battling this weed should consider planting in twin rows and making a timely application of Cadre (3” tall plants or less). 2,4-DB can be used to slow down the growth of sicklepod but rarely will it provide complete control. As a last resort, Gramoxone (paraquat) can be applied in a Non-Selective Applicator (rope-wick, wiper, or sponge).”
