mi-crop-weather State Michigan Crop Weather Released May 10, 2010 Week Ending Date May 9, 2010 Issue MI-CW1910 Agricultural Summary Cool and Damp Four days were suitable for fieldwork during the week ending May 9, according to the USDA, NASS, Michigan Field Office. Precipitation varied from 1.97 inches in the eastern Upper Peninsula to 4.93 inches in the southeastern Lower Peninsula. Average temperatures ranged from 3 degrees below normal in the western Upper Peninsula to 1 degree above normal in the southeastern Lower Peninsula. It was too wet and cool for fieldwork for much of the state towards the end of the week. Some areas in the north had snowfall. Effects of recent frost have not been fully assessed although some damage is expected. "The week started out great, but did a 180 degree turn with the rain Friday and Saturday. The rain was needed, but we did not need the freezing temperatures of this week," a reporter in the central west region stated. Calving was proceeding well. Field Crops Report Field Crops Weekend rains were welcomed, however, more rain and warmer temperatures were needed. Frosty mornings had corn and soybean growers concerned. Wheat progressed and was in Feekes growing stages 5 to 7. There were reports of powdery mildew, in some areas. Growers, in the Thumb, were applying Fungicide and in the southeast, herbicide spraying was complete. Alfalfa was growing well and ranged from 10-14 inches tall. The first cutting could begin as early as next week in the southeast, if the weather permits. Oats and barley were progressing well. Stands looked good and herbicide applications were being made in the central region of the State. Corn and soybeans planting continued, as conditions allowed. Early planted fields of each had begun to emerge. In the central region, applications of pre-emergence herbicide, on corn, occurred. Corn and soybean planting progress continued as the highest on record. Some soybeans, in the south central, have been underwater for several weeks. Growers were monitoring the progress to determine if replanting should occur. Emerged sugarbeets have their second leaf pair. Fruit, Vegetable, and Specialty Crops Report Fruit Growing degree days were still about two weeks ahead of normal around the state. On Wednesday, April 28, there was another freeze. Temperatures fell into the 20's in low-lying areas, possibly reducing crop potential. Apples ranged from bloom in the west central to petal fall with fruit size 4 to 6 mm in diameter in the southwest and southeast. Spotted tentiform leafminer was flying, and the weekend rain increased potential for apple scab infection in the southeast and southwest. Peaches were at shuck in the west central, southwest, and Grand Rapids areas and were at shuck split in the southeast. European plums were at petal fall in the west central and northwest and at shuck split with fruit 4 to 6 mm in diameter in the southwest. Strawberries ranged from starting to bloom in the southwest to first bloom and 20 to 30 percent bloom in the southeast. Sweet cherries ranged from early shuck split and petal fall in the northwest to out of the shuck with fruit size between 8 to 12 mm in diameter in the southwest. Tart cherries were at petal fall in the west central, northwest, and southeast and were in the shuck and at shuck split in the southwest. Pears were at petal fall in the west central and northwest with fruit at about 8 mm in diameter in the southwest. Pear psylla were laying eggs in the southeast and southwest. Blueberries were at first bloom in the southeast and near full bloom in the southwest. Grapes were at late bud swell in the northwest; shoots were about three inches long and flower clusters were separating from the shoots in the southwest. Vegetables Overall, progress in the field was ahead of schedule. Many acres of black plastic were laid in preparation for warm season crops. Recent rains aided cole crop progress, but halted fieldwork towards the end of the week. Onion, carrot, sweet corn, celery, lettuce, beets, parsley, peas, squash, and radish seeding or transplanting continued. Seeded field onions emerged. Carrots did not make enough growth to see rows, and irrigation continued. Sweet corn, continued to emerge. Cabbage has been established for several weeks. Planting of tomatoes and cucumbers continued under protective tunnels. Overwintered spinach did well. Cutting and shipping of hothouse rhubarb continued. Potatoes were emerging in early planted fields. Asparagus was emerging and harvest was underway. Last week's frost damaged about half of the emerged spears in the Oceana area. English peas were six inches tall in southwest Michigan and still progressing.
