Northeast ND (06/21/18)

Information from the Northeast region of North Dakota.

It’s been a great week for plant growth and development in the northeast unless your fields were in the hail associated-storm areas. The earliest wheat is at heading stage and the later seeded wheat is at stem elongation. Soybeans are up to V3 stage. Sunflowers are between V4 and V6. Canola is at the end of its vegetative stages and starting to bolt.

At the LREC station, blister beetles have been observed in faba beans. There is no economic threshold for blister beetles. According to Saskatchewan Pulse Growers literature, blister beetles can move into faba beans, feed in swarms, and leave the fields. The biggest concern would be if faba beans were cut for livestock feed and the adult beetles were present as they contain an irritating and toxic chemical, cantharidin. These beetles can also be found in alfalfa, soybean and canola.
