Northwest ND (05/12/16)

Information from the Northwest region of North Dakota.

The rain in April was welcome and needed after a very dry winter in NW ND. Rainfall totals for the month ranged from more than 3” in southern portions of McKenzie County to less than 1” in parts of Divide County. Rainfall totals tended to decrease as you moved north.

Planting is well underway in most areas and many producers are done seeding small grains and have moved on to broadleaf crops. Lentil and pea acreage is up this year and some farmers have had trouble finding lentil seed for purchase. Farmers took advantage of the warm and dry first week of May to continue planting and start spraying winter cereals. Cutworm activity has been reported in SW ND and in eastern Montana as far north as Sheridan County. Growers and crop advisors should monitor fields of both small grains and legumes for signs of cutworm activity. Scouting fields intensively as the crop emerges is recommended to catch cutworms at their early development stages (< 1” long) which have the most potential to cause damage. Once cutworms reach their full size (1.5” to 2” depending on the species), spraying is not likely to protect yield because the majority of crop loss due to cutworm feeding has already occurred.
