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 →

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

Saving money when it comes to trips across the field with a sprayer can be appealing, but it’s important to keep some things in mind when deciding to mix herbicides with other pesticides and/or fertilizers.  With these types of applications, you risk mistakes on application timing, appropriate gallons of water per acre, and possibly using incorrect nozzles, all of which can result in poor efficacy.  However, you also risk crop injury with some of these combinations.  Continue reading →

It is amazing how insect populations sync up with the crop.  Like our corn crop, the first generation southwestern corn borer moth flight has started early.  Usually it starts about now, but some folks have been catching moths in pheromone traps for a couple of weeks, and moth catches are higher than usual.  Moth trapping data are linked under the “Quick Links” menu for SWCB, corn earworm (or bollworm), tobacco budworm and beet armyworm.  Compared with this week last year, moth catches are Continue reading →

Some fields that missed showers for the ‘nth’ time this spring are dry without a doubt. The bigger corn is trying to twist during the warmest parts of the day and overall color is more variable even where side dress nitrogen has been applied.  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.

Overall, I’m not getting any reports of widespread problems in any crop, but there has been a smattering of several things including … Continue reading →

Just by driving through Tennessee there is no doubt we are a corn state this year.  It seems like everywhere you look there is a field of corn. Much of this corn will get the “layby” application applied over the next 10 days. 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 →
