I saw a post on Facebook this week that said: “if you want to know what it feels like in Georgia, take a hot shower, don’t dry off, and put all your clothes on.” That is about as truthful as it gets. Pecans: Its time to crank up the irrigation in pecans orchards as shell hardening…

Peanuts: We have seen white mold, in small quantities, in Tift County. Be vigilant and aggressive with your sprays. There has been a good bit of false white mold scattered around. Pay close attention to the difference. False white mold does not harm the plant; in fact, the real damage false white mold can cause…

Most important thing is to watch the potential development and buildup of a tropical system in the northern Gulf of Mexico that could bring storms to us late in the week. While the extent and impact of the development of the system is unclear now, it could have significant impact on disease management in Georgia.…

Environmental conditions continue to be favorable for the development of fungal diseases; we still have moisture and some afternoon storms and warm temperatures. Such will certainly favor the development of white mold and leaf spot on peanuts and continued spread of southern corn rust. All of our crops, and especially peanuts and cotton, are progressing…

Dr. Bob Kemeriat has confirmed our first southern corn rust in Georgia for this season. Late to arrive, but it’s here now and weather conditions are favorable for it to spread. Only one field is known (Baker County) but it could easily be anywhere in SW Georgia. Any corn not yet in dough/dent stages could…

With very hot conditions the past few weeks and adequate rainfall and moisture right now, circumstances are right for an early white mold outbreak. You can begin your white mold program early, for example, using Priaxor at 45 DAP, perhaps even bumping the rate from 6 to 8 fl oz/A), starting the Elatus program early…

Most pecan growers in Georgia have been stretching out their scab sprays over the last several weeks since we have been hot and dry with no rain at all for about a month now. In the absence of any scab pressure, this was the right thing to do but when you stretch your sprays out…

Its been really hot and dry. The combination of hot and dry can be really tough on crops. With conditions like these, we need to be on the look for Aspergillus Crown Rot in peanuts (we have seen it), Lesser Cornstalk Borers in peanuts, hot soil is scorching emerging plants in peanuts and cotton (we…

Sharing some notes from Kemerait. Justin and I are seeing the same. Punishing hot and dry weather will increase Aspergillus crown rot in peanuts and charcoal rot in corn and soybeans. Those could be real problems this year and there is little we can do to stop it. Threat from foliar diseases of corn, soybean,…

Downy mildew has been detected on cucumber in Echols County. These observations indicate that inoculum of downy mildew is currently in southern GA counties and under favorable conditions potential disease outbreak in cucurbit can occur. I would suggest our cucurbit growers to look for the downy mildew symptoms in their fields and start applying protective spray of below stated fungicides. Watermelon: Rotation (foliar application) with Orondis Opti; …
