North Central ND (05/24/18)

Information from the North Central region of North Dakota

Over the last week, the Minot NDAWN weather station recorded some much welcomed rain – though we are looking for more. Minot received about 0.15”, Bottineau 0.35”, Crosby 0.06”, Garrison 0.05”, and Rugby 0.38” of precipitation. Precipitation remains part of the short term forecast. Soil temperatures (bare) continue to rise, ranging from the mid-50s to the mid-60 degrees (NCREC/Minot - 67˚F, Bottineau - 56˚F; Crosby - 62˚F; Garrison - 60˚F; Rugby - 54˚F).

Warm temperatures appear to be forecasted for the next seven days across the area. Planting continues throughout the region, especially with canola and soybean. Small grains and pulses appear to have emerged or should emerge shortly.

Canola Striped and Crucifer Flea Beetle populations are slowly continuing to climb on the North Central Research Extension Center sticky traps. This is an indicator that scouting should begin as crops continue to emerge. This should be done regularly until canola reaches the 4th to 6th leaf stage. Most damage is likely to occur during the first two weeks following crop emergence. For foliar insecticide applications, the action threshold arrives when 20-25% defoliation has occurred to plants younger than the 4th leaf stage. For more information on the Canola Flea Beetle, please refer to the NDSU Extension “Integrated Pest Management of Flea Beetles in Canola” publication (E1234).
