Potato leafhopper injury (yellow leaf tips) in peanuts. These insects cause no economic damage in peanuts and are easily controlled if desired.
The brown spots on the peanut inside the hull have a reddish/brown water soaked margin which is typical of tomato spotted wilt virus in peanut. The unaffected skin of the peanut is still pink.

Cotton Defoliation

Camp Hand – UGA Cotton Specialist

There are three ways to determine if a cotton crop is ready for defoliation:

  1. Percent open boll – the crop needs to be between 60 and 75% open depending on uniformity of the crop in the field. To calculate this you divide the number of open bolls by the total number of bolls and multiply by 100. This will be one of the most accurate methods but can be time consuming.
  2. Node Above Cracked Boll – you count from your uppermost first position cracked boll to your uppermost first position harvestable boll. A visual can be found below.
  3. Sharp knife method – cut into the uppermost harvestable boll and check seed coat/cotyledon development. If the lint strings out, seed coats are dark, and cotyledons are fully developed, that boll will open.
