The Dakotan:
This is Ag Issues with Neil Roberts.

Neil Roberts:
Welcome to another edition of Ag Issues. Our guest today is NDSU, crop protection specialist, TJ Prochaska from the North Central Research Extension Center and T.J.. Cereal aphids have just been found in North Dakota this year. Where are they at and what does this mean That's right.

TJ Prochaska:
Two of our six IPM scouts throughout the state discovered cereal aphids in fields this last week. Tommy Crompton in Fargo, India. Sue Scout and then Brianna Holzman from Dickenson area. She found them both in the southeast and southwestern part of the state. These are common to some of our small grains, so their arrival means populations could begin to build in the coming weeks. Keep in mind, they can transmit diseases such as barley yellow to our fiber. So scouting will be key over the next few weeks.

Neil Roberts:
All right. Good stuff, T.J. And we'll have more on the cereal aphid when we come back.

Neil Roberts:
Backing cereal aphids with T.J. Prochaska today on air issues. T.J., I understand there are three common types, correct?

TJ Prochaska:
That's correct. The three most common types of cereal aphids to North Dakota include the green bug, the bird treated aphid and the English green aphid. As we're scouting over the next few weeks where want to think about the stage of your plant to what the economic threshold may be in a vegetative stage, usually for a year. As we move into the heading stage three and theses four to seven aphids and finally and of thesis through medium now could be eight to 12 aphids percent. These will be the numbers to utilize on average after scouting your fields to consider in chemical application Always remember those at greatest risk are later planted fields that will attract these migrating aphids.

Neil Roberts:
All right. Good stuff as always, T.J. that'll put a wrap on this report. If you missed one. Check us on the website at agissues.com. Until next time, I'm Neil Roberts.
