Almost two weeks ago the California Rice Experiment Station (RES) had its annual field day. It was a great opportunity to see fist-hand the research going on at the station.

I visited a field a few weeks ago in the Woodland area. Older leaves showed discolored tips and margins, and necrotic spots. Leaf tips eventually turned brown and die. The grower was worried it might have been blast, because of some of the lesions were elliptical and resembled blast lesions.

I've been receiving reports of high armyworm populations this summer. You can always find some armyworms in rice fields, but I have rarely seen fields that needed a treatment due to armyworm injury. Defoliation caused by armyworms is not uncommon.
