Calls have been coming in from several areas across the province reporting fields that have reached threshold and need to be sprayed. The most recent hotspots include Huron County along lake Huron, Bruce County near Tara, fields north of Barrie, York and Durham and a large number of acres between Belleville and Cornwall. Just coming back […]
It is a strange season. Things that shouldn’t be happening yet are and it is really messing us all up in terms of catching things in time before they become a problem. I just had a call from Laura Neubrand that she has found true armyworm in a late planted wheat field near Exeter that […]
High aphid numbers are being found in fields in counties bordering Lake Simcoe (Simcoe, Durham and Victoria). Spraying has been necessary in many of the fields that have been scouted. Scouting is advised in all fields in that region, starting first with the fields that were not treated with Cruiser. Cruiser treated fields should not be […]
First off, I apologize for not updating the blog for the last little while. I’ve been busy with setting up the SouthWest Diagnostic Days and just ran out of time. But let me catch you up on a few things that have taken place but I am also hoping that others who have been out […]
I’ve had a few calls come in this week about this issue. Some reps are starting to find about 15 – 30 aphids per plant and want to know if they should tankmix some insecticide in with the herbicide since they have to spray the weeds this week anyway, in hopes of getting ahead of the aphid […]
We are starting to scout our soybean sites for 2009. Our weekly scouting results are available on the IPM PIPE Network at: http://sba.ipmpipe.org/cgi-bin/sbr/public.cgi?host=All%20Legumes/Kudzu&pest=soybean_aphid We will be updating these maps weekly and will include any key observations and recommendations within the commentary for both soybean aphids and bean leaf beetles. To see the Ontario commentary, you need to […]
After very little effort on our part, we were able to find soybean aphids on soybeans in the Arva Ontario area. Only 5-10% of the plants had 1-15 aphids per plant on average but we found them in every field that was within the VC, almost V1 stage. Similar reports are coming in from Eastern Ontario. […]
Okay..it is a busy week on the insect front. Sorry..two posts in one day but I want to get the message out! Bean leaf beetle adults are active in emerging soybean fields. We are starting to see feeding damage in several fields in the southwestern counties. These beetles have been waiting a while for soybeans to […]
Heard from two credible sources that soybean aphids are on VC and V1 stage soybeans at London’s AAFC (North East side of London) as well as a few fields in Eastern Ontario and Southern Quebec. I will be doing a more thorough search this afternoon North of London too to see how widespread the aphids are colonizing […]
On the conference call with my US counterparts yesterday, it was mentioned that fields in NE Iowa are starting to see soybean aphids colonize soybeans there. This is a good indication that once our soys are emerging we should be scouting fields once a week to monitor for aphids. Particularly those4 fields that are first […]
The first report of spraying for armyworm in sweet corn in Essex County came in today. We are not sure how heavy of infestation to expect in other fields but wheat and newly emerging corn fields should be scouted in Essex, Chatham-Kent, Lambton, Elgin and Middlesex counties asap. Armyworm reports from Essex tend to give […]
Just in case some of you are keen and plan to be scotuing this long weekend, there are a few critters you should be watching for. Alfalfa weevil (AW) larvae are starting in some fields. So far just the smaller 1st and 2nd instars but warmer weather will help them grow too. Stay ahead of […]
