SPIDERMITES: I have a sneaking suspicion that spidermites are making their way into those fields that haven’t had rain in a while. We have had situations in the past where not only have they popped up in soybeans and were being disregarded as “drought stress” symptoms but also in seed corn, especially around or just after […]
A lot of calls are coming in this week from growers and reps who have fields that are hovering around the 250 aphids per plant range. With the poor weather and wheat harvest some are anxious to make the call if they need to spray. In fact, there are some rumours out there that some are spraying […]
This is a ladybeetle larvae. They can be black or a dull grey/purple with orange or yellow markings. If they are shaped like an alligator, they are a ladybeetle larvae. It will be an adult ladybeetle soon. Both the larvae and adults feed on aphids. The black velvet coloured aphid on the right is […]
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 […]
Now that we are getting into the R1 (beginning bloom) stage of soybeans, we have a bunch of research to do on soybean aphids including trying different combinations of water volume, pressure and nozzle configurations and testing new novel insecticides for future registrations. But we need sites. So anyone that finds soybean fields (>25 acres) with aphids […]
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 […]
