Crop Reports

High corn rootworm (CRW) pressure in 2020 is challenging current Bt rootworm hybrids and several Ontario growers have reported unexpected injury by CRW. This indicates that possible cross resistance has occurred, where even pyramid hybrids with multiple rootworm traits are impacted. Currently, we know that several fields with injury in Huron, Perth and Durham Counties are being investigated. There are…

This article was written by Bailey Fleet, University of Guelph. Bailey is a summer student under the USEL program. Bailey worked under the supervision of Nick Wilker from the U of G wheat breeding lab and Joanna Follings from OMAFRA. Phosphorus (P) is important for the proper growth of cereal crops. P has been found to be a limiting nutrient…

Forage Options to Replace Silage Corn

Corn

Key Points: Rotating out of corn is the most effective way to reduce populations of Bt-resistant corn rootworm. To replace silage corn for 2021, establish fall rye or winter triticale immediately after 2020 silage corn harvest. After the cereal silage comes off in mid-May, establish sorghum-sudangrass and take two cuts. An energy source will need to be supplemented; producers should…

Scouting Guidelines to Determine Possible Rootworm Resistance

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….

Managing to get the most from available water Water is the most important limiting input for crop production. In more than a couple of the past years, producers across the province have been forced to watch while their crops suffer from dry conditions in the heat of summer. Other than irrigation (which is rare for field crops in Ontario), there’s…

Bean Leaf Beetle Pod Feeding Activity

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…

Winter canola seed sales have been very strong and Ontario acres in 2020 are expected to be higher than ever before. While research on the crop has been limited, some recommendations are outlined below based on experience over the past few years and experience with spring canola in Ontario. Field Selection Fields should have good drainage and low clay content….

There are currently three key topics for forage production: nitrates, potato leafhopper, and planting annual forages for fall production. Nitrate poisoning of livestock is a risk in a dry year In a dry year, high nitrate levels in forages are a concern. Fast-growing grass species, such as corn, sorghum-sudangrass, and cereals are most likely to accumulate nitrates. Nitrogen moves from…

Photo above: Potato leafhopper damage (called “hopper burn”) is frequently mistaken for insufficient water. To maximize the forage yield of fall cereals next spring, research from New York state suggests planting fall rye or winter triticale 10-14 days before the optimal winter wheat planting date (Figure 1).   September 1st is the deadline to report summer-seeded New Forage Seeding acres…
