White Mold Risk Summary The risk level for this disease has receded northward slightly as temperatures have increased, but is still high in some areas. Next two-week risk interpretation: Condition are favorable for white mold infection in Wisconsin, Michigan, and northern Minnesota extending into ND. For regions with moderate risk, the risk can be high for soybeans which are flowering with a closed canopy, if white mold mushrooms are found, or the soil is moist and the field has had white mold previously. Weather conditions in August will influence the extent of damage to infected fields. One-month risk map Soybean White Mold Risk Forecast For period of July 20 – August 17, Issue Date: July 21, 2013 One-Month Weather Outlook For next 30 days, temperatures are to be cooler than normal for most of the Corn Belt. Precipitation is to be normal (3-4 inches) or above normal (above 4.5 inches) for areas north of the Missouri – Iowa boarder and stretching across the region to include most of Ohio. What to do? High: Spray fields where soybeans are flowering and the fields have a history of white mold infections. Moderate Scout fields and weigh other risk factors Low or Very low Monitor forecast model

Corn Gray Leaf Spot Risk Forecast For period of July 20 – August 17, Issue Date: July 21, 2013 One-Month Weather Outlook For next 30 days, temperatures are to be cooler than normal for most of the Corn Belt. Precipitation is to be normal (3-4 inches) or above normal (above 4.5 inches) for areas north of the Missouri – Iowa boarder and stretching across the region to include most of Ohio. Grey Leaf Spot Risk Summary The risk of gray leaf spot infection has not changed dramatically from the last forecast. Next two-week risk interpretation The risk is high in east-central Illinois and Indiana, especially for early planted corn. For most of the US Corn Belt, the risk is moderate. In regions with moderate risk, diseased leaves may be found first on the lower leaves of the plants. One-month risk map What to do? High : Treat susceptible hybrids and weigh risk factors for other fields Moderate Scout fields and treat as conditions warrant Low or Very low Monitor risk forecasts

Corn Northern Leaf Blight Risk Forecast For period of July 20 – August 17, Issue Date: July 21, 2013 One-Month Weather Outlook For next 30 days, temperatures are to be cooler than normal for most of the Corn Belt. Precipitation is to be normal (3-4 inches) or above normal (above 4.5 inches) for areas north of the Missouri – Iowa boarder and stretching across the region to include most of Ohio. Northern Leaf Blight Risk Summary The risk of northern leaf blight remains at similar levels from the last forecast for the Corn Belt. Next two-week risk interpretation The risk of infection is high for parts of Indiana and Ohio and is moderate for most of the US Corn Belt, including eastern Iowa, most part of Illinois, southern Wisconsin and southern Minnesota. It remains relatively light for the western Corn Belt. One-month risk map What to do? High : Treat susceptible hybrids and weigh risk factors for other fields Moderate Scout fields and treat as conditions warrant Low or Very low Monitor risk forecasts

Soybean Brown Spot Risk Forecast For period of July 20 – August 17, Issue Date: July 21, 2013 One-Month Weather Outlook For next 30 days, temperatures are to be cooler than normal for most of the Corn Belt. Precipitation is to be normal (3-4 inches) or above normal (above 4.5 inches) for areas north of the Missouri – Iowa boarder and stretching across the region to include most of Ohio. Brown Spot Risk Summary Risk of this disease has increased in parts of Ohio, Iowa, and Minnesota. Next two-week risk interpretation The risk has increased in southern MN, eastern IA, and part of IL. It remains high in southern Ohio and Kentucky. This disease sets a condition for premature defoliation later in the summer where brown spot has become established. One-month risk map What to do?
