WSMB Offers Free Soybean Cyst Nematode Testing

Shawn Conley, Paul Esker, and John Gaska The UW-Madison Agronomy Department, in cooperation with the Wisconsin Soybean Marketing Board, is again offering free soybean cyst nematode (SCN) soil testing for Wisconsin growers. This program is intended for growers to sample several of their fields in order to identify if SCN is present and at what […]

A Snap Shot of Argentina Agriculture

Shawn Conley and Paul Esker Paul and I had the opportunity to spend the last week in the Pampas region of Argentina with fellow scientists Seth Naeve (Minnesota), Palle Pedersen and Jason DeBruin (Iowa), and Chad Lee and Jason Sarver (Kentucky). During this time we had an opportunity to meet with several growers, agricultural agencies, […]

Preliminary Soybean Yields

The 2008 soybean harvest is just getting under way. For most of the growing season, the soybean crop has been about 150 to 200 GDU’s behind the 5-year average. Fortunately for WI soybean growers, the unseasonably warm weather we have been enjoying over the last 10 days has quickly advanced our crop towards maturity. However, […]

Check Combine Settings to Minimize Soybean Harvest Loss

Growers should take extraordinary precautions this year to check combine settings throughout the harvest day especially if they switch soybean maturity groups. Much of the rainfall that occurred in the dry areas of WI occurred too late to aid early maturity group soybeans (these soybeans were physiologically mature-R7 growth stage prior to rain); however many […]

Stress on R6 Soybean

I have logged many miles across Southern WI the past week and have noticed several pockets of soybean that could use some rain. The U.S. Drought Monitor service verifies my wind shield scouting as it places most of southern WI in the abnormally dry category (Image 1). Across southern and central WI the average soybean […]

Sun Scald, White Mold, and Drought Stress

A survey of our central, north central, and northern soybean variety trial locations was conducted on 8/12/08 and 8/13/08. The soybean crop ranged between the R4 and R5 growth stages. Across most of WI we still remain ~150 gdu’s behind the five year average. Soybean aphids were present at all trial locations. We have been […]

Soybean Growth Stage Does Not Matter: Soybean Aphid Threshold Should Remain at 250 Aphids per Plant

High commodity prices coupled with receding flood waters have some growers pushing their soybean planting dates well into late July. As these soybeans emerge and develop they will be greeted by an increasing population of soybean aphids. Dr. Eileen Cullen UW Field Crops Entolomogist suggests the following plan of action to manage the soybean aphid […]

Preliminary Wheat Yield Estimates

The 2008 winter wheat harvest is a little behind schedule due to decreased heat units, delayed maturity, and green stems. The advantage of this delayed harvest however will likely be noticed once the combine hits the field. Preliminary yield reports from Dane (Dave Fisher), Winnebago (Nick Schneider), and Green Lake (Carla Hargrave) counties show winter […]
