Crop & Pest Report
Maps detailing corn accumulated daily growing days, percent normal rainfall, departure from normal average air temperature, and accumulated wheat growing degree days.
Information from the south-central region of North Dakota.
Information from the Northwest/North-Central area of North Dakota.
Information from the Southwest region of North Dakota.
The late start to field work in the northern counties of North Dakota and Minnesota just became a bigger problem with the high rainfall amounts received in the last few days. We are fast approaching the final planting date for many crops in this region.
Previously, updates on glyphosate-resistant kochia were sent via the AgDakota list serve. Last summer there was widespread concern in eastern North Dakota that glyphosate was not killing kochia.
Question: Do you have any information on control of foxtail barley is seeded crops and prior to seeding?
Over the last 20 years of wetness, the elimination of tree rows has progressed. There has been little wind erosion during the wet years. On May 14, however, many growers were given a little taste of what it must have been like at the beginning of the 1930’s.
The Plant Pathology Department at North Dakota State University will again be providing the potato Blightline service at no charge to the potato industry of North Dakota and western Minnesota in 2013.
If you want to have Fusarium head blight alerts sent to your email or mobile phone this summer, you may sign up for those free alerts
The multi-state Fusarium head blight prediction tool also is activated for the season, and many southern states have already experienced risk during the flowering stage of their crops.
The NDSU small grain disease forecasting site is now activated for the season.
Many of you are aware that Marcia McMullen, Extension plant pathologist at NDSU, retired in the fall of 2013.
Rhizoctonia solani causes Rhizoctonia damping-off of seedlings and root and crown rot of older plants. This pathogen is becoming more widespread and damaging, probably because planting is done in conditions more favorable for infection and disease development and the use of more host crops in the rotation probably increases inoculum population.
Planting of the 2013 sugarbeet crop is progressing rapidly in North Dakota and Minnesota. Rains that were really needed stopped planting operations at American Crystal Sugar Company (ACSC) where just over 80% of the projected acreage was planted.
A number of factors impact the decision of what crop to plant in a given year. Many of these factors deal with issues that are not necessarily biological in nature. As examples, crop insurance, equipment availability, marketing potential, availability of seed, and past experience with the crop are some of the factors that are carefully considered before a decision is made as to what crop to plant. Biological factors also play a huge role in that decision as planting is delayed. Some crops yield poorly when late planted late, others fail to mature.
The recent rainfall has curtailed planting at a critical time as the last planting date approaches for many crops and regions of the state. In many areas, excessive rainfall has caused localized flooding, ponding, and saturated soils. For fields previously planted, excessive moisture can be damaging to the germination process and to plant development.
The NDSU recommended established plant population for soybean is 150,000 evenly distributed plants per acre. In order to get the proper plant population it is important to correct for the germination percent of the seed.
National Assessment Shows Geographic Distributions and Trends of Pesticide Use, 1992-2009 The U.S. Geological Survey’s Pesticide National Synthesis Project provides a new interactive national maps and trend graphs on the usage of 459 pesticides in agriculture for each year during 1992-2009 for the U.S.
Using the Degree Day (DD) map (below), adult alfalfa weevil should be emerging soon (around 250 accumulated DD) in the southeast corner of North Dakota. The southwest region of North Dakota is around 150 accumulated DDs. With the recent rains, alfalfa should be growing fast which will help mitigate the injury caused by alfalfa weevil feeding.
