IPM in the News

[8/26/2016] Minnesota Crop News has reported that a single adult brown marmorated stinkbug was collected in sweep net samples from a soybean field in Dakota County on August 17, 2016. 

[8/25/2016] The Minnesota Department of Agriculture (MDA) is pleased to announce a new round of funding for the Sustainable Agriculture Demonstration Grant Program.

Minnesota Crop News has published an article on palmer amaranth.

[8/17/2016] A new study published by Anh Tran, Tavvs Alves & Bob Koch, has found Sulfoxaflor to be less harmful to beneficial predators of soybean aphids.

[8/10/2016] Insecticides are an important tool in the IPM toolbox for protecting crop yields from pests. However, we need to keep in mind that many of the insecticides we use to manage crop pests are also toxic to beneficial insects, such as predators and pollinators. This article will provide an overview of some considerations for reducing the risk of impacting pollinators (e.g., bees and some flies) when foliar insecticide applications are made to crops. 

[8/8/2016] Growers now have access to two more miticides for use against twospotted spider mites in soybean. These miticides are Agri-Mek SC (Syngenta) and Zeal SC (Valent). These are welcomed additions to the limited suite of chemicals for management of twospotted spider mites in soybean. They represent insecticide groups (modes of action) not used for soybean aphid. 


[8/3/2016] History has shown us many times that over-reliance on pesticides often results in development of pesticide resistance in pests. Last summer in parts of southern Minnesota, some pyrethroid insecticides (bifenthrin [e.g., Brigade, Tundra , Hero and others] and lambda-cyhalothrin [e.g., Warrior and others]) failed to provide adequate control of soybean aphid. Historically, these have been among the top performing pyrethroid insecticides for soybean aphid management. Follow-up laboratory bioassays confirmed resistance  (10- to 44-fold resistance) to these insecticides in a soybean aphid population collected near Lamberton, MN.

[7/28/2016] Japanese beetle, an invasive pest from Asia, is making its presence known. These large beetles with shiny green- and copper-colored bodies can be found feeding on many plants, including soybean, in agricultural areas that are in proximity to the Twin Cities, Rochester, and other urban areas in southeastern Minnesota. This beetle is not yet widely distributed in the state and is not likely to be in fields outside of these areas in southeastern Minnesota.

OMAHA (DTN) — The U.S. Environmental Protection Agency has scheduled a scientific advisory panel meeting this fall to review the widely used herbicide glyphosate, but offers no indication in a Federal Register notice Tuesday, if the panel will consider the conclusions of an EPA cancer assessment review committee that found glyphosate poses no significant cancer risk.

soybean aphidBefore soybean aphid was identified as a pest of soybean in the U.S. in 2000, insecticide applications to northern soybean crops were rare, targeting sporadic insect and mite outbreaks. Although large infestations have been relatively uncommon since the early to mid-2000’s, the soybean aphid is unquestionably still the key insect pest of soybeans in many North Central states. A tremendous amount of research and observational data has been obtained for this pest since its introduction and we have the tools and the knowledge to manage this pest effectively.

WASHINGTON, D.C. (DTN) — USDA boosted corn acres above pre-report expectations to 94.15 million acres, up 7% from last year. Soybean acres also rose to 83.69 million acres, up 1% from last year.

usda [4/29/2016] U.S. Department of Agriculture (USDA) will provide a new financing option to help farmers purchase portable storage and handling equipment. Farm Service Agency (FSA) Administrator Val Dolcini and Agricultural Marketing Service (AMS) Administrator Elanor Starmer announced changes to the Farm Storage Facility Loan (FSFL) program today during a local and regional food roundtable in Columbus, Ohio.

soybean cyst nematode[4/20/2016] The soybean cyst nematode (SCN) is a serious pest of Minnesota soybean and has been managed with crop rotation and soybean varieties with resistance to SCN. This approach is becoming less effective, however, because SCN populations virulent on (able to reproduce on and damage) SCN resistant soybeans are increasingly widespread. A seed treatment biological (Clariva™ Complete, Syngenta Crop Protection®) has been labeled for management of SCN.

Bruce Potter[4/6/2016] Soybean cyst nematodes have become so commonplace that farmers may wonder if there is anything they can do about it. Putting up the white flag is rarely the best solution - especially when these nematodes can reduce soybean yields by 5-8 bushels per acre. "The way to look at SCN is they make a lot of other problems worse," said Bruce Potter, University of Minnesota Integrated Pest Management specialist.

Palmer Amaranth[4/5/2016] A survey conducted by the Weed Science Society of America (WSSA) has ranked Palmer amaranth, also known as Palmer pigweed, as the most troublesome weed in the U.S. Weeds in the Galium genus (cleavers, catchweed bedstraw and false cleavers) ranked as the most troublesome in Canada. 

Harmonia[3/31/2016] Drs. Bob Koch and Bill Hutchison are mentioned in a press release, as co-authors on a new review article, summarizing global impacts of the invasive, multicolored Asian lady beetle, often referred to in Europe as the Harlequin Lady Beetle.

[3/29/2016] Herbicide-resistant weed worries continue to build beyond the farm field. The Office of Inspector General (OIG) for the Environmental Protection Agency announced Friday it will investigate how EPA has managed weed resistance issues related to herbicide-tolerant crops EPA has approved.

EAB [3/21/2016] The Minnesota Department of Agriculture (MDA) has identified emerald ash borer (EAB) in Wabasha County.

[3/17/2016] WASHINGTON – U.S. Environmental Protection Agency (EPA) announced two grants to help reduce students’, teachers’ and staffs’ exposure to pests and pesticides in our nation’s schools, while saving money, energy and pesticide treatment costs.
