NDSU Crop and Pest Report - May 16, 2013
Crop & Pest Report
Weather and Crop Phenology Maps (05/16/13)
Maps detailing corn accumulated daily growing degree days, percent normal rainfall, departure from normal average air temperature, and accumulated wheat growing degree days.
Southwest ND (05/16/13)
Information from the southwest region of North Dakota.
The Never Ending Dandelion Problem (05/16/13)
The following is an edited version of information printed in an earlier Crop and Pest Report article by Dr. Jeff Stachler: As the number of tillage passes and depth of tillage decreases, dandelions become more prevalent in agricultural fields.
Where did my Pre Herbicide Go? (05/16/13)
The condensed planting season may have diminished use of PRE herbicides. The high winds earlier this week may have moved soil particles from the dry soil surface. If PRE herbicides were applied some of the herbicide may have moved with soil particles.
Potato Seed can cause Irregular Emergence (05/16/13)
Potato seed is aged in two ways, chronologically and physiologically. The chronological age is the number of days that have passed since the tubers were harvested. The physiological age refers to the internal age of the seed as affected by biochemical changes that take place within the tuber.
Corn Emergence (05/16/13)
Only 18% of the corn acreage was planted in North Dakota as reported by NASS on Tuesday. This is well behind the long term average of 43% for the same period. Nevertheless, conditions in most of the state are currently nearly ideal for planting. If current conditions continue, the outlook is good for most of the corn to be planted by the last planting date. Warm days and strong winds have been drying the surface rapidly.
Canola (05/16/13)
Canola is a major oil crop in the northern Great Plains. In 2012, 1,450,000 acres of canola were harvested in North Dakota with an average yield of 1,420 pounds per acre. North Dakota accounted for approximately 83 percent of the canola acreage harvested in the United States.
Update on Alfalfa Weevil (05/16/13)
Using the Degree Day Model for alfalfa weevil, we can expect adult alfalfa weevil emergence around 250-300 DD
Adult Alfalfa Weevil Emergence Delayed (05/09/13)
Alfalfa weevil was very damaging in North Dakota last year due to its early emergence and the drought stressed alfalfa. The early emergence may have been due to eggs, which successfully overwintered during the mild winter of 2011/12, and as a result they hatched into larvae which started feeding on foliage earlier than normal.
Weather and Crop Phenology Maps (05/09/13)
Maps detailing corn accumulated daily growing degree days, average air temperature, percent normal rainfall, and accumulated wheat growing degree days.
Southwest ND (05/09/13)
Information from the south-central region of North Dakota.
Crop Management Field School (05/09/13)
NDSU Extension Service’s annual crop management field school will be offered Thursday, June 20, from 9 a.m. to 4:30 p.m. at the Carrington Research Extension Center. The school will provide hands-on training on crop and pest management using field research and demonstration plots.
South-Central ND (05/09/13)
Information from the south-central region of North Dakota.
Four Important Pages in the ND Weed Guide (05/09/13)
From winter meetings NDSU specialists and researchers have shown that infestations of herbicide resistant weeds are increasing. They are increasing not only in scope of area but also in number.
Planting Date Trumps Preplant Fertilizer Application (05/09/13)
The planting season, especially in the northern half of North Dakota, will be extremely compressed. Less than normal fall fertilizer application will mean that many fertilizer dealers will have long waiting lists for fertilizer application this spring. Since the dates are already ticking away, and planting dates optimal for highest yield potential will be reached in the next week or two depending on where the field is located, waiting several days for a fertilizer applicator to show up before planting is not a reasonable decision.
Projections for 2013 Sugarbeet Crop plus Soil Temperature and Sugarbeet Seed Emergence (05/09/13)
The projected total sugar use for 2013 is expected to be 11 million short tons raw value. About nine million tons of this sugar will be produced in the US with just over 5 million tons coming from sugarbeet. Total US sugarbeet acreage is expected to be about 1.2 million acres.
Late-Planting Small Grains and Corn in 2013 (05/09/13)
The long winter and slow melt of the snow this spring has substantially delayed planting this year. Small grains are cool season crops that require relatively cool temperatures in order to achieve high yield potential. Therefore, when planted late, small grains develop during warmer temperatures that are detrimental to yield.
Army Cutworms In Alfalfa (05/09/13)
Large numbers of army cutworms have been reported in alfalfa fields in southwest North Dakota, near Rhame. Larvae (or caterpillars) overwinter as partially mature larvae and are ready to start feeding on alfalfa, winter wheat, canola and other early planted crops as soon as the temperatures warm up.
Lentil Production (05/09/13)
Lentil (Lens culinaris Medik.) is produced on more than 450,000 acres throughout the U.S. (2012), including the 158,000 acres harvested in North Dakota with an average production of 1,190 pounds per acre.
