August Peanut Pointers
Scott Monfort, Extension Peanut Agronomist, UGA
The crop condition has improved dramatically over the last month as a result of the continual rain and
warm conditions. The one thing on everyone’s mind is Tomato Spotted Wilt Virus (TSWV). Another thing grower’s need to keep in mind is some of these TSWV plants might start crashing as we approach maturity. I have already starting seen this in some non-irrigated fields.
Growers need to be reminded that they cannot spray any magical product to minimize the TSWV. All they can do is try to irrigate when needed and manage pests. With it being August 10th, we also need to start talking about maturity and maturity clinics. A majority of peanut counties have received rain over the last few weeks allowing the crop to keep moving forward. I am not sure what affect the 95-degree temperatures and dry weather had on the early blooming and pegging. It might have caused some fields to be a little behind but who knows.
Common questions/comments that need to be considered during a Peanut Maturity Clinic
1. What is the Peanut Variety?
2. What is the Age of the Peanut?
3. Are the peanuts Irrigated or Non-Irrigated?
4. What are the conditions of the Plants/Vines?
x Encourage growers to bring plants not just pods
5. Are there any disease issues?
6. What is the short and long range weather forecast?
7. Remind growers that 200 pods are needed. This would be off several plants pulled from a
representative spot(s) of the field.
8. The more information you have, the better prediction of maturity you can make.
RUNNER-TYPE VARIETIES AVERAGE MATURITY
AUNP 17: is a medium maturing peanut (140 to 145 days). Good peg strength, good level of TSWV,
white mold and leaf spot resistance
FloRunTM ‘331’: This is a medium- maturing peanut (140 to 150 days). Good level of TSWV resistance
Georgia-06G: Georgia-06G is a medium maturing peanut (140 to 145 days). Moderate Level of TSWV
and leafspot resistance
Georgia-09B: Georgia 09-B is a medium maturing peanut (135 to 140 days). Some peg strength issues.
Susceptible to leafspot.
Georgia-12Y: This is a medium-to-late maturing peanut (150 days +) — Good peg strength, high level of
TSWV, white mold and leaf spot resistance. Very susceptible to Rhizoctonia Limb Rot.
Georgia-16HO: is a medium maturing peanut (140-145 days). We have observed slightly higher
incidence of leaf spot late in the season. We have also observed some peg strength issues in wet
Georgia-18RU: is a medium maturing peanut (140-145 days). We have observed slightly higher
incidence of leaf spot late in the season. This variety is more susceptible to TSWV and have seen some
issues with vines crashing because of TSWV and Diplodia.
Georgia-20VHO: is a medium maturing peanut (140-145 days). This is a new variety for most growers. It
is low growing variety. It has good level of TSWV resistance. The one negative for this variety is that we
have observed significant pod loss in wetter years.
