Northeast ND (07/07/16)

Information from the Northeast region of North Dakota.

In the last two weeks, we are finding low levels of stripe rust in the spring wheat. Much of the spring wheat has flowered in the region. The scab timing fungicide application will help protect fields from rust infection. June’s turbulent weather-affected areas are reporting bacterial leaf streak in wheat. Bacterial leaf streak will look bronzy and when leaves are held up to the light, you may see dried, glossy bacterial exudates on leaves while stripe rust is a bright yellow-orange in color. We have also see some general yellow mottling on flag leaves from environmental factors.

Sclerotinia fungicide applications are being applied on canola. The region has three faces this year. We have farms dealing with summer storm damage –loss due to hail, waterlogging, and disease; farms which are looking excellent with waist-high corn and green waves of grain; and finally, farms who have been battling uneven emergence or late stands from spring weather events.
