Researchers expand tillage options related to dry beans

There are few weed control options for dry bean in conservation tillage

Reading Time: 3 minutes More than half of the dry bean trials at the Centralia Research Station are now done using strip tillage equipment.  “We want to go strip till, because that’s what we’re evaluating it for, growers who want to go strip till or minimum till. We want to be closest to the practices that growers are using […] Read more

Flight of the western bean cutworm

OMAFRA Field Crop Report for August 25

Reading Time: 2 minutes It is safe to say that western bean cutworm (WBC) is a pest that we can rely on entering corn and dry beans every year in Ontario. Though a frustrating pest to scout for, using traps to monitor moth flight has helped us better predict when to expect peak moth flight occurs, which is shortly […] Read more

Western bean cutworm is considered to be the most economically harmful to Ontario’s corn crop.

Syngenta maintains WBC trait advantage

Reading Time: < 1 minute Syngenta’s NK seed brand continues to expand its corn offerings, including more hybrids with its Viptera trait — the only one effective against western bean cutworm.

Field Talk with Matt Rundle: Ideal timing for scouting of WBC is now

Reading Time: < 1 minute On this edition of Field Talk, Farmtario reporter Jennifer Glenney, speaks with Matt Rundle, sales agronomist with Harriston Agromart, about Western Bean Cutworm scouting. Rundle says the ideal timing to scout this nasty pest is now. Peak moth flight, and egg masses are the best things to look for within grower’s fields. Western Bean Cutworm […] Read more

Western bean cutworms cause damage to corn and other crops.

Western bean cutworm laying low so far

Western bean cutworms haven’t been a major issue this year but their full impact is still unknown

Reading Time: 3 minutes Will western bean cutworm (WBC) be to 2019 what DON was to 2018? According to the evidence thus far, probably not. In fact, WBC appears sparser than expected. That said, Tracey Baute, field crop entomologist and WBC expert with the Ontario Ministry of Agriculture, Food and Rural Affairs, says several factors have combined to make […] Read more

Western Bean Cutworm trapping network expands

Western Bean Cutworm Trap Network includes more pests, larger geographic coverage and new name

Reading Time: 3 minutes The growing success of the Western Bean Cutworm Trap Network, and issues with other corn pests across Eastern Canada, led to the expansion and renaming of the network, now known as the Great Lakes and Maritimes Pest Monitoring Network. Why it matters: The trap network enables OMAFRA and participants to monitor peak flight timing of […] Read more

Dave Hooker talks about mycotoxins in corn at the Bayer Dead Weeds tour.

Managing corn mycotoxins needs scouting, hybrid choice

Farmer can reduce risk of mycotoxins, including through insect and spore management

Reading Time: 3 minutes Generally dry conditions have reduced the threat of mycotoxins in corn this year, although rains during humid days could change that as corn moves to tasselling and silking. However, Dave Hooker, of the University of Guelph’s Ridgetown College, says that historical monitoring of mycotoxin levels by the Ontario Ministry of Agriculture Food and Rural Affairs […] Read more

Western Bean Cutworm taking on more than corn

Reading Time: 3 minutes Western Bean Cutworm is now the most economically significant pest in corn, but it’s quickly becoming a challenge in other nearby crops, especially dry beans. Why it matters: Scouting for Western Bean Cutworm (WBC) is much more challenging in dry beans than corn, so knowing the status of nearby corn fields and increasing moth trap […] Read more

Greig: Lessons learned from Ontario crops’ pest pressures

Reading Time: 4 minutes The warmer winter and subsequent drought defined the 2016 cropping season in Ontario, resulting in more disease and insect pressures and then challenges managing them. Three agronomists gave an overview of the 2016 cropping season at the SouthWest Agricultural Conference in Ridgetown, outlining challenges and wins for the year. Leanne Freitag, Cargill’s manager of agronomy […] Read more

Corn trait’s action on western bean cutworm seen ineffective

Reading Time: 2 minutes Ontario entomologists have similar concerns to U.S. counterparts who have taken an unusual step by sending an open letter to seed companies about failures in control of western bean cutworm (WBC) by the Cry1F trait. Seven leading U.S. agriculture entomologists posted the letter this week, after a high-WBC-pressure year in the U.S. Midwest caused them […] Read more
