2) Delayed cotton with high yield potential
It’s important to check out the boll load in this situation. Keep in mind that August 25th was the last effective bloom date. That means on average there is a 50% chance that lint from today’s bloom will make it into the picker. I wouldn’t worry about losing squares from plant bugs at this point. If there are bolls smaller than the diameter of your thumb, then it will be important to protect these from plant bugs and stink bugs. Plant bugs prefer smaller bolls in this category and stink bugs prefer larger bolls in this category. Both can cause injury to the boll through seed feeding and by transmitting pathogens causing boll rot.
3) Cotton with bollworm eggs
We are now entering the fourth generation of bollworms produced right here in North Carolina. With every generation, there are usually more and more in the system. So that means that some folks are noticing really heavy flights and some significant egg lay in cotton. Fortunately, while these eggs may hatch, the larvae rarely get past the first or second instar stage. It’s always good to keep an eye on your cotton if it’s still bollworm-susceptible for those once in a blue moon scenarios. However, I don’t think we need to roll out with more egg threshold sprays at this point in the season.
