The Dakotan:
This is Ag Issues with Neil Roberts.

Neil Roberts:
Welcome to another edition of Ag Issues. Our guest this week as India's crop protection specialist TJ Prochaska from the North Central Research Extension Center. And T.J., we previewed canola and flea beetles a few weeks back. It looks like good timing. As I understand, you're getting lots of reports now.

TJ Prochaska:
You bet. This warmer weather has really allowed some of these emergences to take place. Free beetles are hopping throughout the area. I've already actually taken some calls already. Insurance adjusters in some instances have already approved some replant due the severity of their feeding. Of course, canola free beetle can lead to major injury from emergence to about the six leaf stage, typically resulting in pits in the leaf and the cutter leading or even shotgun like holes in the small plant.

Neil Roberts:
All right. Good update on that, T.J., thanks. And hey, we'll have more on flea beetles when we come back.

The Dakotan:
You're listening to Ag Issues with Neil Roberts on the Dakotan Network.

Neil Roberts:
Talking flea beetles today on air issues with T.J. Prochaska. And T.J., tell us what to scout for.

TJ Prochaska:
Right. Scouting for damage is going to be key important, even be the trigger to get you out there. But one thing to understand is to look at the species you're looking at. Of course, cruciferous striped flea beetles are in the area. The Aquarius there is India zoo extension research is indicating control two striped three beetle is not as effective as it is with the Christopher Flea beetle.

TJ Prochaska:
So understanding that species will be important for your insecticide will be important once you hit 20 or 25%. Defoliation, if needed for your insecticides, can be used with this type of a population at D7 and D4 insecticides, c treatment may be needed.

Neil Roberts:
Good stuff, T.J., and thanks for that. That concludes this edition. 80 is on. Catch us on the website at agissues.com. Until next time. I'm Neil Roberts.
