Cotton Research Verification Weekly Update
Author: Arkansas Row Crops

General Comments: All of the cotton verifications are continuing to improve this week. Some of the fields saw some rain over the past weekend; however a few of the fields didn’t receive any rain until this week after the weekly visit. I will publish those rainfall totals in next week’s update.                                                                                                                  
Clay- Variety: Deltapine 0912 B2RF The Clay County field is continuing to grow this week. The field had obtained a small amount of hail and wind damage from last weekend’s storms but it was just cosmetic damage. The field remains clean from the Roundup and Dual application. The farmer had plowed his water furrows and laid his poly-pipe forirrigation. 

Craighead- Variety: Deltapine 0912 B2RF The Craighead County field was growing well and had received a ½ inch rain from the weekend’s thunderstorms. The field had received some wind damage, however it was already recovering. The farmer was able to fertilize the field and plow the water furrows. Data was taken at the field to put in the Phaucet program. Roundup and Warrant were recommended to control the existing weeds and for pre-emergent control after the middles were plowed.                                                                                                                                           
Mississippi- Variety: Deltapine 0912 B2RF Rainfall prevented the farmer from applying the Gramoxone and Valor. More weed spots had come up over the week. Gramoxone and Valor were recommended in the row middles and Direx and MSMA were recommended for underneath the cotton. (*Note- according to the MP 44 cotton needs to be at least 6 inches tall before using Direx and MSMA)                                                                                                                           
St. Francis- Variety: Phytogen 375 WRF The St. Francis County field continues to improve after the rough early start. Glyphosate resistant pigweed is the number one problem in the field at the present time. 40 ounces Gramoxone and 2 ounces of Valor were recommended for control. A rain moved through the area yesterday however if it wasn’t enough to activate the Valor the farmer is going to irrigate to activate the Valor. The field was beginning to square.                                                                                                                                                                                                             
Phillips- Variety: UA 48 The Phillips County field is beginning to square over most of the field. It remains clean from an application of MSMA and Direx.    

 Lincoln- Variety: Stoneville 5458 B2RF The Lincoln County field is growing well and is squaring. Some pigweed spots have been noticed and the farmer is going to make a Dual application before watering to prevent pigweed from emerging. The farmer had plowed his water furrows and laid the poly-pipe. Unless the field receives a rain in the next few days the farmer will probably start the irrigation this upcoming week. A few plant bugs were caught in the sweep net so we will start to monitor that situation in the upcoming weeks.

Jefferson- Variety: Stoneville 5458 B2RF The Jefferson County field received 1 inch of rain over the past week. It did sustain some hail damage but the new leaves looked healthy. The field is ready for the nitrogen to be applied and the farmer is going to plow it in and then come back with an application of Roundup and Dual to control the grass that’s in the row and to put down a pre-emergent herbicide.
