These are 16 row plots replicated 4 times of NuCotn 33b and irrigated. The last 10 days have seen a lot of the cotton crop go from pushing to add a record number of fruit to slowing to a stop and slip backward. Many of the eggs were deposited on bloom tags and bracts low in the plants. We saw a number of small larvae puncturing through stuck blooms to feed on the ends of small bolls. The population was still somewhat mixed both bollworm and budworm.
Whiteflies continue to increase and in some areas are producing honeydew.
If more that half the plants in a field have whiteflies, spray applications may be warranted. It will most likely take a minimum of 2 applications and in many cases 3 at no greater than 5-day intervals to get complete control of these pesky critters. Orthene or Monitor are still the choices for control. Aphids are coming back in a few places, but the fungus seems poised to reinfect these fairly quickly. Mites are still cropping up in some areas, as well.
