Frost Update After the hard frost on Monday there was some concern that the crop may have been damaged. Looking at fields Thursday AM although there was visible damage the extent across the Green Gold fields was very minimal. The picture on the right is generally what I would see in most of the fields. There may be damage to 5% of the plants but looking closely I could see new growth from the bud at the tip of the plant. The picture to the right was taken at the Steinbach field where the crop jumped 5 inches from Monday. Here you can see how the new growth has grown 2 inches above the frost damage.
Alfalfa Weevil Due to the recent warm weather there is the possibility of alfalfa weevil emerging. Adult alfalfa weevils emerge before the 167 GDD accumulate they lay eggs on the alfalfa stems which hatch in one to two weeks. The larvae emerge and start feeding on the growing tips of the alfalfa plant. This feeding can go on for 2-3 weeks before pupating. Typical feeding takes place up to about the 350 GDDs, which is typically when alfalfa reaches the 180 RFV and is ready to cut. For more information click on Alfalfa Weevil
1Alfalfa weevil feeding (taken 2013) Growing Degree Days Because each spring is unique in temperature, precipitation and growing degree days (GDD),the date hay is ready for a first cut can vary as many as three weeks from year to year. It typically takes 300 to 350 GDD to reach RFV of 180 for the first cut. If we look at the accumulation to date, we are at about 170 GDD.
