mi-crop-weather State Michigan Crop Weather Released July 30, 2007 Week Ending Date July 29, 2007 Issue MI-CW3007 Agricultural Summary Mild With Little Rain Six days were suitable for fieldwork during the week ending July 29, according to the USDA, NASS, Michigan Field Office. Precipitation varied from 0.04 inches in the eastern Upper Peninsula to 1.33 inches in the southeast Lower Peninsula. Average temperatures ranged from 2 degrees below normal in the southeast Lower Peninsula to 6 degrees above normal in the western Upper Peninsula. Rainfall was scattered around the State, giving growers varying field conditions. Many farmers appreciated the precipitation, while others continued to bear the drier weather that has been experienced lately . A farmer in the east central mentioned that, "The rainfall was very selective again this week. The driest areas were missed again and the crops are losing yield that cannot be restored." Another reporter in south central said that, "The small amount of rain revived the crops a little but if the hot dry weather persists for another week as predicted, corn production will have major negative implications." Field Crops Report Field Crops Dry conditions continued across much of the State, as variable precipitation provided limited relief to crops in some areas. Varying rainfall fell short of growers' expectations as the lack of moisture continued to increase concerns for crop condition and quality. Corn condition varied depending on the amount of precipitation received. Field development ranged from tassel emergence to pollination. The presence of western corn rootworms were reported in some fields. Soybeans continued to bloom. Spider mite infestation was prevalent in many fields. Growers were advised to continue to scout fields for this pest as dry conditions persist. Oats continued turning yellow. Harvest began in some areas. Alfalfa re-growth continued to be short. Harvest of second cutting was completed in many areas; the third cutting began in fields where re-growth was sufficient. Dry beans continued to bloom. Sugarbeets continued to add growth. Wheat harvest was completed in many areas. Fruit, Vegetable, and Specialty Crops Report Fruit Apples are predicted to mature a week to twelve days ahead of normal. The predicted 2007 full harvest date for Red Delicious in the Grand Rapids area, for example, is September 26; the normal date is October 5. Some early varieties were picked in the Southwest. Blueberry harvest continued; growers irrigated to maintain fruit size. Early season fresh market peach harvest continued across the State. Sweet cherry harvest was finished. The dry growing season kept diseases to a low level. Tart cherry harvesting was completed in the west central and continued in the northwest. Quality was still very good except for cherries damaged by wind whip. Grape berry and shoot growth have been slowed by dry conditions. Grape berry moth numbers rose. Pears were 2.5 inches in diameter in the southeast. Vegetables Cooler temperatures helped plants stressed by drought. Areas that received rains saw some additional relief. Carrots continued to grow with fresh market harvest to begin soon. Bacterial blight has been reported in processing carrots fields. Celery harvest continued with good yields. The last of the transplants has been completed. Cabbage and lettuce harvest continued. Cabbage development continued well where irrigation was available. Potato harvest continued for the farmer's markets. Potato Leafhopper numbers remain low. Sweet corn harvest continued for fresh markets. Yields were good from irrigated fields; variable from non-irrigated fields. There were some reports of Stewart's wilts causing losses. Earworm and corn borer have not been a major problem. Watermelons continued to size. Cantaloup harvest began. Cucumber harvest continued. Early fields of cucumbers were being removed and made ready for a second planting. Bacterial wilt and Downy Mildew was a problem in some fields. Zucchini and summer squash harvest continued. Low fresh market prices were diverting some fresh market zucchini to processing. Pumpkins continued to size. Winter squash plantings were doing well. In some areas, vine growth was less than normal with some wilting due to a lack of moisture. Tomato and pepper harvest continued with more fields coming into production. Onions, leeks, and red beets continued to grow. Thrips can be found in some onion fields, but were under control. Snap beans were in good condition, but dryland fields need moisture.
