Tracey - Syngenta AMS soybeans are holding up very well in Quebec according to Martin Lanoutte. very impressive in plots where non AMS had to be sprayed and S22-A1 did not have any aphids of significance. Waht have you seen?

Hi Mike

Thanks for the update. Lagon does not have any fuming action. I think you are thinking of Lorsban, which is not registered on soys and is incredibly detrimentl to the natural enemies that are trying to help. No, I don’t think it is too late to apply Matador or Silencer. If the aphids are closer to the 500 per plant range and you have a deep canopy, you may want to bump up the rate of Matador but most times we still see good success with the low rate. The key is to properly apply the product. To spray for soybean aphids you should set up the nozzles to get a MEDIUM droplet size. Use high water volumes (20 GPA) and high pressures (70 psi), while targeting the spray at the middle of the canopy (not the top as you would for spraying other things). If we see control issues, it is usually due to poor application.

We are reaching threshold levels around the Alfred area also. We will need to spray as soon as field conditions improve. Do you think it’s too late for Matador or Silencer since a lot of the aphids have moved lower on the plant. Would Lagon be a better product to use because of it’s fuming action?

Just sprayed 100 acres of soys for aphids southwest of hensall july 19 09,yes there was enough pressure to warrant spraying. used .4 litres of cygon per acre.I’m sure neighbouring fields are infested as well. Farmers should be scouting fields not just drive bys.

Thanks Tracey.

Yes, Paul was sure that’s what it was. It was in pretty well every stalk along the outside row but didn’t move into the field.

Hi Brent

Did he mean Stalk Borer or is he getting that confused with European corn borer? Here is a pic of Common Stalk Borer : http://www.ipm.iastate.edu/ipm/icm/files/images/stalkborerearly-2.jpg

If it is Stalk Borer, then yes, he is correct. Since the larvae would be in the stalk already, spray would not be effective. Plus, we tend to find this insect only at very low densities and has not reached thresholds in Ontario that I know of.

Let me know if that is what you found. Otherwise, we can see about getting some samples to me to identify.
