Weekly Update

  • Burndown applications are out as are the harrows. Snap beans are being planted and corn is popping. I’ve talked with several of you about delaying any POST applications in corn. It’s best to wait until this little cold snap passes. The reasoning behind this is that the weeds shut down when the temperature drops so…

  • Cotton: Cotton Leaf Roll Dwarf Virus (CLRDV) is becoming more popular over the past two weeks. I posted some pictures below of what the symptoms look like from cotton I’ve found. We are still in the early stages of getting a handle on this disease. Aphids are known to transmit CLRDV but there is no…

  • Cotton: Whiteflies and spider mites are becoming a problem with all of this hot and dry weather. Target spot is a concern and needs to be scouted, I haven’t found any in Tifton yet but conditions are right. I have also found a few places where stinkbugs are getting close to threshold. I’ve talked to…

  • Cotton: Plant bug numbers are spotty. Remember that we want at least 80% first fruit retention going into bloom. Whiteflies are building. The rain that went through this week should have beat them back some but we still need to be vigilant in scouting for them. Nematode problems are starting to show. Water demand really…

  • Cotton: I would start monitoring all squaring fields for tarnished plant bugs. The few fields that have had higher populations have been older cotton. The past trend is that earlier cotton is more susceptible to plant bugs. Pull the trigger if you are at or below 80% retention rate on your first position squares. We…

  • It has been an odd week. First, we lose Dicamba, then we get a 24c label for Liberty, the weather is funky, Mexico is phasing out Glyphosate, and hurricane season is underway with expected above-normal activity. Cotton: Whiteflies have been spotted in cotton. They are not at threshold levels yet but we all know how…

  • Peanuts: Still battling vigor issues in replants. The cloudy weather isn’t helping much either. Dr. Harris says gypsum may be in short supply this year. There is a potential disruption in the supply chain from coal plants transitioning to natural gas and COVID-19. If gypsum is short we have a few options. Calcium through the…

  • Cotton: Grasshoppers and false chinch bugs have been seen in a few places. Grasshoppers can chew through the stem if bad enough. Only treat if the stand is being effected. The immatures are easiest to kill and can be taken out with some Acephate. False chinch bugs can feed on the plant and high populations…

  • Peanuts: It rained this week so I’m sure some Valor injury is going to start showing up. Dr. Prostko has years worth of research that shows peanuts that suffer injury from Valor at 3oz /A will very likely recover with no effects on final yield. Some are ready for cracking sprays. Remember you have about…

  • Corn: Its the time of year for little greyish tan spots to start showing up in corn. 99% of the time this is the result of some paraquat drift. There is no need to worry but if you would like one of us to come and check it out, just let us know. Peanuts: Be…
