Corn Corn Corn Water Water Water

Posted by romeethredge on May 18, 2013

Growers are busy watering corn this week as it has turned off dry. Some corn is head high (V9 or so) and  the tassel will soon emerge so water is needed for top yields. It needs over a quarter of an inch per day at this stage.

I’m seeing a little more NCLB disease this week but only in conservation tillage corn behind a crop of corn last year. I’m seeing lots of round spots due to herbicide drift. We are also seeing a fair amount of Common Rust. Which is a cool season rust that does not cause us any real problem at all.

We have a plot here as part of the “Southern  Corn Rust IPM-pipe” sentinel plot monitoring program (scr.ipmpipe.org). Go to the web site to see Southern rust area updates as to where its been found.

Common rust is darker than Southern rust and often goes through to the leaf underside.

Another curiosity that we are seeing is spider mites in corn. They are on some lower leaves but should not cause yield loss unless they get much worse.

Here's Caleb, Dr. Kemeraits man who is checking corn for disease in a rust resistant and a non resistant hybrid for the US “Southern Corn Rust IPM-pipe” sentinel plot monitoring program (scr.ipmpipe.org).
