Northeast ND (06/22/17)

Information from the Northeast region of North Dakota.

Cloudy days with small rain showers and cool temperatures aided cool season crop development for most of the region. Cool, wet soils have caused iron chlorosis in the soybeans. Could disease start to develop as weather is expected to stay in this cool, light rain pattern? It’s possible. White mold needs 1 to 2” of rainfall about 2 weeks prior to flowering in dry beans. Using the canola risk map as a tool, currently the environment is creating high risk across northern ND. Bloom time is the critical crop stage for infection and the crop isn’t quite there yet in the northeast.

In Benson County, drought has pushed HRSW to flowering in early seeded fields on sandy ground. The moisture came too late. Currently, scouted fields have been very clean for disease. English grain aphids were found in Grand Forks county wheat fields. Herbicide spraying has mostly wrapped up. Sugarbeet crop is looking very good. Canola is nearing bolting stages.

Twisted whorl syndrome in corn occurs when oscillating cold and hot temperatures cause uneven crop development. Goose-necking or buggy whipping can occur. This sweet corn photo is showing twisted whorl syndrome and also was damaged by very high winds from the June 9th severe storm system.
