We are monitoring wheat disease in an effort led by OSU Extension wheat specialist, Pierce Paul.
We follow growth stages of wheat to know when to apply herbicides safely but also to know when, or if, we should apply fungicides. Growers who rely on the height of the crop as an indicator of crop development may miss Feekes Growth Stage 6, a critical growth stage for herbicide application, and Feekes GS 8, a critical stage for managing foliar diseases with fungicides. Do not rely on the height of the plants or calendar dates alone (especially this year) to make your management decisions. Walk fields, pull tillers from multiple places, remove the lower leaves, and examine these tillers for the presence of nodes and the emergence of the flag leaf. At Feekes GS 8 the tip of the flag leaf, the fourth leaf above the first node, is visible.… Continue readingRead More »
