Why be concerned about the Bt resistant rootworm populations showing up in Ontario? Dr. Jocelyn Smith, University of Guelph Ridgetown Campus stands in a field that has cross resistant rootworm.  The grower experienced more than 50% yield loss in this 2nd year silage corn field planted with a pyramid hybrid in 2020.  Jocelyn discusses the impacts of these resistant rootworm…

Baute Bug Blog

Extensive injury by corn rootworm (CRW) to pyramid Bt rootworm (Bt-RW) hybrids was observed in several Ontario counties in 2020, suggesting that CRW populations have developed resistance to multiple Bt-RW proteins. The Canadian Corn Pest Coalition (CCPC) and OMAFRA have developed mitigation recommendations for continuous corn producers, in hopes of knocking back the resistant corn rootworm population present in Ontario….

Baute Bug Blog

Scouting for corn rootworm injury is important to detect potential resistance to rootworm Bt traits and to plan management options for the next growing season. It is especially important to report any fields showing signs of suspected resistance to your corn agronomist and the provincial entomologist. Rootworm larvae feed below ground on corn roots from late May until late July….

Canadian Corn Pest Coalition News Release: Corn rootworm (CRW) has historically been one of the most important pests of corn in Canada and can cause extreme economic loss and increased management costs.  High CRW pressure in Ontario in 2020 is challenging current Bt corn rootworm hybrids and several growers of Bt rootworm hybrids are reporting unexpected injury by CRW to…

Bean Leaf Beetle Pod Feeding Activity

Baute Bug Blog

Reports have been coming in about pod feeding from bean leaf beetle (BLB) in IP, food grade and seed soybeans. Pod damage on crush beans typically does not warrant control. Foliar feeding (defoliation) is rarely the concern this time of year. But BLB can feed on the surface of the pod which exposes the seed inside to pod diseases that…

Here is the latest update on where the trap catches are for western bean cutworm in the region based on trap site data entered into the Great Lakes and Maritimes Pest Monitoring Network. Peak flight for Ontario and most other states and provinces on the network (except Michigan) occurred during Week 11 (Aug 3-9) (see Fig. 1). Trap catches are…

Seeing Lots of Rootworm Adults in Rootworm Bt Fields? Let Us Know!

Tracey BauteTracey Baute July 28, 2020 555 Comments Off on Seeing Lots of Rootworm Adults in Rootworm Bt Fields? Let Us Know!
Baute Bug Blog

Corn rootworm adults emerged a few weeks earlier than usually and are quite abundant this year.  This is particularly concerning when the adult populations are high in corn on corn fields planted with a rootworm Bt hybrid. This could be an indication that rootworm populations have developed resistance to the rootworm Bt traits involved. To know for sure if your…

Many reports are coming in about silk clipping in corn. Three main culprits include corn rootworm beetles, Japanese beetles and redheaded flea beetles. Regardless of which one is doing it, it comes down to when and where they are clipping and by how much. Corn silks can grow as much as an inch or more a day, though most of…

A number of reports have come in that cereal aphid populations are increasing. Scouting cereal fields is advised. Natural enemies are present in many fields so I recommend using the Cereal Aphid Manager app to help you decide if a spray is required based on your aphid and natural enemy populations. The cereal aphid threshold is 12 to 15 aphids…
