Grasshopper Workshop Set For March 29
After eastern Montana and western North Dakota farmers and ranchers endured the second largest grasshopper outbreak of the last 35 years in 2021, they are naturally nervous about what may be coming next, particularly given persistent drought in the region.
And it appears everyone is rightfully on edge. Annual grasshopper surveys taken last fall by the U.S. Department of Agriculture’s Animal and Plant Health Inspection Service (APHIS) indicate another bad year for grasshoppers, with more than 20 million acres in the west predicted to exceed the economic threshold for the pests and another 60 million crowding that number. The vast bulk of the most highly impacted acreage is predicted to be centered in Montana and western Oregon.
To help producers in this area better prepare for the potential onslaught, researchers with the USDA’s Agricultural Research Service (ARS) in Sidney and Montana State University’s Extension Service in Sidney are hosting a free grasshopper workshop entitled “Oh no! Not again! Grasshopper Outbreaks and Management Options in 2022” set for Tuesday, March 29 at the Richland County Extension Office conference room in Sidney. The twohour workshop is free and runs from 10 a.m. to noon.
Workshops speakers include Dr. Dave Branson, Research Entomologist and Acting Pest Management Research Unit Leader at the USDA-ARS Northern Plains Agricultural Research Laboratory in Sidney and Gary Adams, Montana’s State Plant Health Director at USDA- APHIS in Billings. In addition, Dr. Kevin Wanner, Cropland Entomology Specialist with Montana State University Extension in Bozeman, will be featured in a prerecorded segment with tips on managing grasshoppers in cropland systems.
Dr. Branson, who has more than 25 years experience studying grasshoppers in rangeland systems in the northern Great Plains, will discuss the biology and ecology of grasshoppers and how weather impacts them and the potential for large outbreaks. He will also discuss ongoing grasshopper research in ARS, including sustainable rangeland management techniques focusing on the use of livestock grazing and rangeland fire to reduce outbreaks; new predictive tools for outbreaks being developed at ARS and more.
Gary Adams, who has more than 35 years with APHIS’ Plant Protection and Quarantine office in Montana and who oversees grasshopper control programs in the state, will be discussing grasshopper management options in rangeland; available treatments and their limitations, and existing federal spraying programs and private cost share options.
Dr. Wanner’s segment will include information on important pest species in Montana and management options in cropland systems in general, along with management considerations for specific crops, such as winter wheat.
Wrapping up the workshop, will be a question and answer session with the speakers, who in addition to answering other concerns from participants, will also offer insights into outbreak predictions for the 2022 growing season.
Two pesticide points are available for attending this workshop. Attendees participating live online will also be eligible for pesticide points. Categories include Dealer, Agricultural Plant Pest Control, Demonstration and Research Pest Control, Regulatory Weed and Private Agricultural Pest Control.
The workshop presentations will also be available live online.
