Time to put on your Entomology Hat!

Yes, now that the spray season is coming to an end, it is time for the bugs to come out and play! There is starting to be more color to the fields, as the canola is starting to bolt and beginning to flower. It is still early to be sweeping for insects, but it is time to start thinking about it and keeping it in the back of your mind.

Some of the insects you might come across this season are the cabbage seed pod weevil, lygus bug, and diamond back moth larva just to name a few. The thresholds vary depending on each insect, for cabbage seedpod weevils it is 3-4 weevils per sweep where as lygus bugs are 1-2 per sweep. Don’t get confused with the number of diamond back moths that you see, because the adults do not cause damage, it’s the larva you have to watch out for.

The Get More Bushels Super Crop Plot was sprayed on June 23. You are able to see the results already. The Round-up Ready varieties were sprayed with Glyphosate and the Invigor with Liberty and Centurion. The plot is also varying in staging, from cabbaging to just starting to flower. There is still some spotty emergence in some of the test strips.
