This is the last year of the four year on-farm study investigating early season insect pests and efficacy of neonicotinoid and/or diamide seed treatments in corn or soybeans. University of Guelph Ridgetown Campus are looking for participants again this year. The full trial protocol can be found here. Any growers planting neonic, diamide or both […]
Learn, participate and have your say The proposed Plant and Animal Health Strategy for Canada was drafted together by governments, industry and others who play a role in safeguarding plant and animal health. The strategy will protect plants and animals from new and emerging risks by focusing efforts more on prevention and increasing partner collaboration […]
The dry season is leaving the edible bean and soybean crops susceptible to two-spotted spider mites, especially now that wheat harvest is wrapping up. In some years, spider mites will also feed on corn leaves. Spider mite damage and management are very similar for soybeans and edible beans. Because of the dry conditions and likely […]

Cereal leaf beetle is starting to show up in some fields in Ontario. A few locations tend to experience a higher frequency of infestations including fields near Dresden, Bolton, Stayner, Seaforth, and Clinton. But this does not mean that other fields in Ontario are not at risk. Cereal leaf beetle (CLB) adults are beetles with […]
Once corn and soybeans emerge, keep an eye out for crop injury. If you experience stand loss from wireworms, grubs, seedcorn maggot, bean leaf beetle (in soybeans only) or corn rootworm (in corn only), then you can choose to have an Inspection of Crop Pest Assessment done this spring. If the stand loss thresholds are […]
Now is a great time to scout for wireworms and grubs. With the recent warm weather, soil temperatures have reached 10oC, which means that wireworm baits will be most effective right now and grubs will also be feeding close the soil surface. How much time there is to scout for these pests depends on how […]
Before this brief cold wet weather some planting got started over the last week in some areas. The warmer weather had brought spring on into full bloom including dandelions, coltsfoot and some trees including maples, willows, popular and even fruit trees. With the flowers come the bees to forage, setting up the potential for the […]
I’m big on “To Do Lists”. Some may even say I am obsessed with them. But they help me get things done. With the 2016 growing season approaching, it is a good time to review what the requirements are for using Class 12 pesticides (neonic treated corn and soybean seeds) in Ontario. Here is a […]
As of July 1, 2015, new requirements for buying and using neonicotinoid-treated corn and/or soybean seed are being phased in to allow growers to adapt to new requirements. This fall (2015) – to prepare for the 2016 growing season Required for Seed Order To purchase and plant 50% or less of your total grain corn or total soybean crop for […]
Trap counts are still quite high this week in Ontario which indicates that peak flight hasn’t plateaued yet. So there is likely still lots of egg laying happening. Moths will prefer to lay eggs in later planted corn that is still in pre to early tassel stages or will find dry bean fields nearby. Just […]
Lots of people have been sending in pics of eggs, nymphs or adult stink bugs and asking which stink bug it is. So I thought I’d try to help sort them out for you. There are predatory stink bugs and then there are plant feeding stink bugs. It is important to make sure you can […]
With the exception of the last few hot days, these slightly cooler than norm July temps are ideal for soybean aphid development. They can double their populations in a matter of days when temperatures are moderate. There haven’t been many reports of threshold levels being found in the fields so I am a little worried […]
A few tweets, text messages and reports from our scouts have indicated that WBC egg masses are being found in corn this week. The next two to three weeks are key for scouting and managing WBC for the bulk of the corn crop. Though the typical hot spots (eg. Bothwell area) are more prone to […]
