We have been blessed with another great harvest season and it appears we may be able to finish harvest with little rain.  Here on the 5th day of Oct, I would guess the average cotton acre within the state has already received the first application of harvest aids and is very close to seeing a picker.  Even so, several acres have not been defoliated.  This has led many to call with concerns about the cooler temperatures in the forecast over the weekend and several have asked if it is simply time to defoliate based on calendar date.   Continue reading →

defolguideTennessee’s 2016 cotton crop is rapidly maturing and many of our acres will receive the first shot of defoliant in the next week.  There are many factors to consider in determining timing, products and rates.   In an effort to outline these decisions and provide harvest aid recommendations for the Mid-South, the 2016 Mid-South Cotton Defoliation Guide has just been updated and is now available online.   To access the guide, click the image above or the included link.  Please keep in mind that this was compiled as a regional guide and should be used in conjunction with your previous experiences.

Cotton turning . . . too soon?

IMG_4307The call of the week (beyond target spot) has concerned cotton ‘turning’.  In the dictionary of cotton rhetoric, ‘turning’ refers to the shift in canopy color from dark green to shades of yellow and red, or senescence, which usually coincides with the second or third week of football season.  Over the past week, the crop has definitely made a turn towards finishing out the season .  . .  and kickoff for the first game is still a few days away. The general concern is this change has occurred much more rapidly and earlier than we would like.  So are we looking at premature senescence and yield penalties? Continue reading →

IMG_1778Observing canopy characteristics during the growing season is a good way to understand the plant’s response to its environment.  Occasionally, portions of the canopy may develop reddish-purple or red tones.  The synthesis of anthocyanin, the pigment which typically causes the reddening, is commonly increased after leaves are exposed to light following multiple abiotic and biotic stresses.  Continue reading →

Many fields in West TN reached first flower well-before the 4th.  I wouldn’t be surprised if over half of our acres will be blooming by the end of the week.  With rain and warm temperatures in the forecast, expect very rapid plant growth in areas which have adequate moisture as we move into flowering.  For those who have not applied an early shot of a plant growth regulator (PGR), you should consider doing so very soon.  Several points should be considered when attempting to regulate growth in 2016.
