CROP
& INSECT SITUATION Cotton has set its last harvestable bolls for all practical purpose. Even on late cotton it is impractical to consider a boll after this date as one which will contribute to final yield and quality. It definitely would be questionable as to any efforts to try and protect this fruit from potential insect damage. We continue to find cotton bollworms (0-5000 per acre), beet armyworms (0-24,000), fall armyworms, cabbage loopers, lygus, and aphids. |
With the exception of beet armyworms and Lygus, which are still a potential threat in some area fields, numbers of most insects have drop considerably this week. Aphids have disappeared from some fields. Based on the current heat unit projections, and cutting bolls the last couple of days, 90% of the cotton acreage will be safe from worm pest by the end of this week. Some of the late planted or replanted cotton will take another week or so to finish it out. Projections also put this cotton which will be safe from insects this week at a point of being ready for a harvest aid starting around September 15th. I mention this in order that you begin to think about your financial resources to properly finish out this crop. A crop which is ready for harvest aid by mid-September will have much time for weathering losses if you plan on waiting for a late October freeze. Peanuts have been maturing rapidly in most cases as well. The hot dry conditions have slowed the threat of disease. However, peanuts can go down fast during this time and make the harvest process difficult to recover all potential yield if plant health is not protected and maximized by preventative fungicides. |

Weeds have given many a producer "the fitz" this summer. At this point weeds become more a cosmetic problem and a concern for adding seeds to the seed bank. Competition from most of these weeds has already occurred. Just be careful not to damage nuts or spend money on something which may not return. What I mean by not return - some of these weeds have already developed mature seeds and any control measures would be a waste. Irrigation as I mentioned earlier has many producer asking "when can I shut the wells off". My answer is when the crop has enough water to finish it out and not put it under any stress which it cannot tolerate. I have visited some fields which have full size bolls at the top which cannot be cut with a knife (at least 15-20 day old boll). These fields can take moderate stress or wilting in afternoon as long as they recover the next morning. If they do not recover than you should have irrigated longer. As I mentioned last week though - I would rather err on the side of not being too wet. Under the current conditions that would seem to be an impossibility. However, we all know that the weather can change in an instant. COTTON
