Started blasting some early planted (first half of April) peanut samples yesterday. On the maturity board they were behind, maybe ready around 155-165 days versus the average 140 DAP timeline for GA-06G’s.

Dryland peanuts, planted early April, blasted end of August, Crisp Co, 2020.

Stand issues, cool-wet spring, and abnormally dry summer could all be contributing factors. With many fields having been re-planted to fill skippy stands, going to see split crop patterns out there.

Please give me a call (229-417-7062) once you’re ready to check your fields and I’ll blast samples. I can pull them or you can drop off hulls still on the vines at our office anytime.

While scouting peanuts the past two weeks I documented Tomato Spotted Wilt Virus (TSWV) incidence by visually counting symptoms in 50′ transects. I saw average estimates ranging from 3-26% TSWV incidence in Crisp Fields. Sounds like in many cases if anything was put in furrow it was an imdacloprid like Velum and acephate over the top later in the season, but treatments have certainly differed field to field. TSWV is a disease UGA’s peanut team is tracking year to year. If you have any fields you want me to put boot tracks in just give me a call.

Lastly, Dr. Bob Kemerait and other local Ag agents have been reporting a sudden increase in the amount of boll rot in cotton over the past two weeks. Recently I’d only seen boll rot affecting a small numbers of lower canopy bolls sporadically in Crisp. Yesterday I walked a few fields that had boll in the bottom canopy of every plant I observed.

Biggest “take-homes” are: 1) there’s nothing we can spray for the boll rot symptomology at this time, 2) there are four causal agents that can be blamed, with the latter two the most common, being Phytophthora, bacterial, Colletotrichum, and Diplodia….and 3) not 100% sure why we’re experiencing the increase of boll rot this year….could be the perfect storm of weather conditions…either way we are on the lookout. Again, if there’s a field you want me to put bootprints into just give me a ring.

Thanks y’all.
