Week Ending May 17 – Complete moth trapping results for bollworm (corn earworm), tobacco budworm, beet armyworm and southwestern corn borer are linked below. Clearly, the warm winter resulted in good survival of overwintering larvae as southwestern corn borer moth catches continue to be very high is some locations including traps located in Continue reading →

Actually, thinking of thrips as raining from the sky is pretty accurate; and we are getting a pretty good flood in most areas.  Many people are reporting 2-15 thrips per plant on cotton from the cotyledon stage up to the second true leaf.  These calls are pretty easy to answer.  Spray if multiple thrips are present on plants with less than two true leaves.  Certainly apply a foliar insecticide if the first or second true leaf has obvious signs of thrips injury … Continue reading →

False chinch bugs are a pest that can kill cotton and soybean seedlings.  I see them in a few fields almost every year, but they are causing more widespread problems this year, with reports from Madison, Gibson, Haywood and Hardeman Counties.  Infestations almost always occur in Continue reading →

WEEKEND SHOWERS WELCOMED BY FARMERS

Showers and thunderstorms provided some needed relief this weekend, but it has been so dry recently that all regions of the state continue to need a general soaking rain. Crops continue to develop at rapid rate well ahead of normal. Corn planting is complete, all emerged and in mostly good condition. Cotton and soybean planting and tobacco transplanting were the main farm activities last week. Fertilizing, spraying post-emergence herbicides and hay harvest were also major farm activities. The wheat crop is ripening and farmers expect to begin harvest within the next two weeks. Continue reading →

 Dear Colleagues

The University of Tennessee Weed Tour will be on Thursday, June 21 at the West Tennessee Research & Education Center in Jackson, TN.  Registration will start at 8:30 A.M. and the tour will begin at 9:00 A.M.. Continue reading →

Dry weather forced most producers to temporarily quit planting soybeans last week and into this week with planting resuming in limited areas that received rains this weekend.  We are about 25% planted at this point but without enough moisture to get seedlings out the ground in many parts of the state, seeds are better off in the bag.  Stands have been uniform and look good for beans planted in late April and the first few days in May but some folks that pushed it on moisture are going to have mixed results with partially emerged stands that will need to get some rain to finish the job.  Beans that are Continue reading →

Rainfall continues to be spotty across Tennessee. Some locations have continued to have adequate moisture while other areas continue to miss the passing thunderstorms. Continue reading →

Scouring Rush

Over the past several years many have had concerns about scouring rush creeping into crop production areas.  Scouring rush is not a typical agronomic weed. It normally grows along fence rows, ditch banks, and low lying areas.  However, in long term no-tillage production systems scouring rush is increasingly encroaching into crop production areas.

SCATTERED SHOWERS PROVIDE LITTLE RELIEF

Unusually high temperatures and sunny days combined to minimize the benefits of scattered showers that fell in many areas across the state. Reporters in all regions reiterated the need for a general soaking rain. Row crops were holding on with three-fourths of the corn and winter wheat acres rated in good-to-excellent condition. Crop development continues to advance well ahead of the normal pace. Pastures declined some from the previous week, but cattle were reported to be mostly good condition. Other farm activities this week included post-emergence herbicide and fertilizer applications, cutting hay, scouting for insects and diseases, harvesting strawberries, and continued assessment of freeze damage on fruit crops. Continue reading →

There have been a number of reports of Palmer amaranth up with newly emerged soybeans and cotton. There are various reasons for this development.  The number one reason is pre applied herbicides were not activated by rainfall and the pigweed emerged with the crop. Continue reading →

A GOOD GENERAL SOAKING RAIN NEEDED!

Rainfall totals throughout most of the state last week were below normal, which led to short-to-very short soil moisture supplies in almost forty percent of the farmland. All crops and pastures, however, remain rated in mostly good-to-excellent condition with development advancing well ahead of the normal pace. Continue reading →

Horseweed 17 days after 12 oz dicamba/22 oz Roundup PowerMax

Horseweed (marestail) still present in fields after dicamba and glyphosate applied 2 to 3 weeks ago has been the most common call of the week. Many want to know if the twisted up horseweed will go ahead and die or if it will recover (picture right).

Some of this can be determined by pulling some individual horseweed plants out of these fields and breaking the stem in half.  If the stem is beginning to discolor or Continue reading →
