Japanese beetles are showing up in corn, soybean and cotton. Of these cotton is their least favorite. These showy beetles often hang out in groups and draw a lot of attention. Fortunately, they rarely cause yield loss in field crops. The beetles will feed on leaves, flowers and corn silks. Japanese beetles have a wide host range which includes many ornamental plants. They were introduced into the northeast U.S. nearly 100 years ago and have been slowly spreading south and east ever since. They only have one generation per year, and the adults started emerging last week. Adults will continue to emerge for several more weeks and will persist into July. Larvae are white grubs that feed underground and are sometimes a pest of turfgrass. Continue reading

Challenges Managing Glyphosate-Resistant Palmer Amaranth in Soybeans
![overview Palmer over run soybean field after flexstar gt](https://news.utcrops.com/wp-content/uploads/2011/06/overview-Palmer-over-run-soybean-field-after-flexstar-gt-150x150.jpg)
We have lost several soybean fields to glyphosate-resistant (GR) Palmer amaranth over the last several days (Picture left of one). These fields had been sprayed when the Palmer amaranth averaged about 2 to 4” in height with Flexstar GT or Prefix plus glyphosate. I have seen similar results with our research at Jackson on GR Palmer amaranth with many of the Continue reading

WHEAT HARVEST TAKES OFF AS HIGH TEMPS PERSIST
Spurred on by another week of hot, dry conditions, Tennessee’s wheat farmers were able to harvest well over a third of the crop last week. Producers have harvested more of the winter wheat crop by this time of year than any other spring since 2006. Warmer than average temperatures coupled with Continue reading
Heat Damage to Soybean
Extreme temperatures are leading to some peculiar heat damage symptoms showing up in soybean. I have had a number of calls and text messages with pics of plants that are dying on top of the ground, laying over at the soil line, etc. Continue reading

Glyphosate-Resistant Palmer in Soybeans
Palmer amaranth is getting away from us quickly! A considerable amount of the Palmer pigweed in soybeans is now 2 to 4” tall. Continue reading

WEATHER CHANGES COURSE FOR FARMERS
Tennessee farmers took advantage of unseasonably hot and dry weather to make progress planting cotton and soybeans last week. Hay producers also made use of the dry conditions and were able to cut significant amount of the state’s hay acreage. By week’s end, corn planting was virtually complete. Continue reading

False Chinch Bugs in Cotton and Soybean
Beginning Friday and continuing over the weekend I received a few calls about false chinch bug infestations in cotton and soybeans. This is an occasional but potentially serious pest of these crops during the seedling stages. They are most often associated with reduced tillage where delayed burndowns allowed certain weeds to persist into the field close to or after planting. My colleague, Angus Catchot, just posted an article about this pest on The MSU Crop Blog site at Continue reading

SOYBEAN AND COTTON PLANTING CONTINUE BETWEEN STORMS
Wet, stormy spring weather resumed early last week, followed by a hot and dry weekend. Although farmers were kept out of some wet fields, planting progress occurred and the wheat and hay crops continued to mature. A third of the state’s soybean acreage was planted by week’s end, placing it about a week behind schedule. At 61% planted, the cotton crop was also about a week behind the average pace.
