Updated Wheat Fungicide Table

With wheat growth and development ahead of normal in 2012, it is important to pay attention to the growth stage when determining if there is a need for the use of foliar fungicides. Active scouting is important to determine which diseases are present and either the incidence and/or severity of each disease relative to wheat […]

Late Season Soybean Diseases

The 2011 growing season has been one of great variability in terms of the weather and its impact on soybean diseases. Early season conditions were cool and wet planting which was then followed by high heat and humidity. Now, as reported in the August 19th blog posting, abnormally dry conditions are being reported in several […]

Goss’s Wilt of Corn

We are starting to receive an increase in the number of reports, calls and/or emails regarding Goss’s wilt of corn. Goss’s wilt is caused by the bacterium, Clavibacter michiganensis subsp. nebraskense. This disease has been on the increase in the past two years, including being found in numerous seed corn and sweet corn fields in […]

Examining Risk Factors Associated with White Mold in Soybean

I just spent the past three days participating in various field days in the western part of the state. These travels really provided an excellent opportunity to examine stand quality across the different field crops, in particular the soybean crop. Soybean stands were pretty variable across these areas, ranging from some really good looking soybean […]

Fusarium Head Blight Update – June 13, 2011

While most of the wheat in Wisconsin has flowered, there are still areas where flowering will occur over the next few days to week. I just spoke with Mike Ballweg in Sheboygan County and wheat closest to the lake is in the Feekes 10.2 to 10.4 range, meaning 1/4 to 3/4 of the inflorescence are […]

New Seed Treatment Poster for Corn and Soybean

With an increase in the number of seed treatments registered for corn and soybean in Wisconsin, it can be a bit daunting to understand what the different products are, and what pest they are targeting or if they are marketed to improve seedling health. Richard Proost and I recently finished a new poster entitled, “What […]

Fusarium Head Blight Risk – June 6, 2011

Currently, wheat in many areas of Wisconsin is starting to flowering or will be over the next few days. The current risk for Fusarium head blight is low based on the Fusarium Head Blight Prediction Center. Rainfall has been rather light the past 7 days, although some locations received rainfalls upwards of 0.30 inches or […]

Fusarium Head Blight – Foliar Fungicides

As we move into flowering in the wheat, in addition to determining if conditions for Fusarium head blight warrant the application of a foliar fungicide (currently, the risk for FHB is low around the state), it is important to pay attention to fungicide product labels since not all products labeled for wheat suppress FHB and […]

Lancaster and Janesville Winter Wheat May 31 2011

Finishing the two-day trip to check on our wheat studies, today I visited the Lancaster and Janesville locations. Wheat at both of these locations is rapidly advancing, with Lancaster being at a very solid Feekes 10.5 (inflorescence completely emerged), while at Janesville, the growth stage ranged from Feekes 10.1 (first inflorescence spikelet visible) to 10.5 […]
