The 9th International IPM Symposium will be held March 19-22, 2018 at the Renaissance Baltimore Harborplace Hotel, 202 East Pratt Street, Baltimore, Maryland, USA. The symposium will begin with the Opening Session on Monday, March 19, 5:00-7:00 pm, featuring a keynote talk by Dr. Dini Miller, Virginia Tech, and presentation of the 2018 IPM Achievement Awards.
The Integrated Crop Management Conference offers workshops focusing on the latest in crop production technology. Experts from Iowa and surrounding states will provide research updates and results in soil fertility, soil and water management, crop production and pest management. Attendees can choose from up to 7 topics each hour. This format allows you to customize your conference experience to meet your interests and CCA credit needs.
Registration and program information for the 2017 ICM Conference will be posted in October.
View this webinar to learn more about the Iowa Pest Resistance Management Program (IPRMP), an Iowa-specific effort to address pests--including weeds, insects and diseases--that can adapt and become resistant to chemical, genetic, and agronomic control practices. The IPRMP outlines approaches for protecting your crops with effective, integrated management solutions that will sustainably control pest
The world’s most widely used weed killer is not responsible for perpetuating Sudden Death Syndrome (SDS) in soybeans, research shows. A collaborative effort among soybean researchers in the United States and Canada and found that glyphosate does not increase SDS severity or adversely affect yields in soybean fields. Scientists from five Midwest universities and the Ontario Ministry of Agriculture Food and Rural Affairs, led by Daren Mueller of Iowa State University (ISU) in Ames, participated in the three-year study.
AMES, Iowa — The Integrated Pest Management program at Iowa State University is hosting its fourth crop scouting competition on Aug. 5 for teams of Iowa high school students. Organizers announced the 2014 theme, Crop Scouting Innovations, this week along with extending an invitation to participate to teams of high school students (those completing grades 9-12).
Japanese beetle is becoming a more common field crop pest in Iowa. Literature shows adults need about 1,030 growing degree days (base 50°F) to complete development. Japanese beetles will continue emergence until around 2,150 degree days. Based on accumulating degree day temperatures in 2014, Japanese beetle adults should be active in some areas of southeastern and southwestern Iowa this week (Fig. 1). Expect adults to emerge in central and northern Iowa in about 7-14 days if warm temperatures continue.
Farmers in the Midwest may be concerned about white mold (also called Sclerotinia stem rot) in soybean this year. The disease, caused by the fungus Sclerotinia sclerotiorum, is not common every year, but farmers who have battled the disease in the past will want to assess the risk of white mold development as soybeans approach flowering (growth stage R1 – plants have at least one open flower at any node).
One thing we have learned from outbreaks of sudden death syndrome (SDS) in years past is that this disease likes it wet. Last year we wrote about the risk of SDS increasing with the early season rain. But at the end of the article we threw in one caveat – soybeans were planted very late in the season, which reduced the risk of SDS developing. And after we published the article, the rains essentially stopped. Fast forward to the end of the 2013 season -- we still had some SDS in parts of Iowa in 2013, but it was not as nearly as bad as it could have been.
Grasshopper activity has been noted this week in Iowa. These insects feed on grasses and weeds, and can become field crops pests. In corn and soybean, feeding is frequently, but not always, restricted to field edges. When crop injury does occur, it usually is related to drought conditions due to a reduction in natural vegetation.
