mi-crop-weather State Michigan Crop Weather Released August 6, 2007 Week Ending Date August 5, 2007 Issue MI-CW3107 Agricultural Summary Hot and Dry Seven days were suitable for fieldwork during the week ending August 5, according to the USDA, NASS, Michigan Field Office. Precipitation varied from none in the northeast and east central Lower Peninsula to 0.91 inches in the southwest Lower Peninsula. Average temperatures ranged from 3 degrees above normal in the southwest Lower Peninsula to 7 degrees above normal in the Upper Peninsula and northwest Lower Peninsula. Farmers were concerned about crop yields and field conditions due to the lack of sufficient rainfall in the State. Within the past week, many areas did not receive any rainfall. A farmer in the northwest Lower Peninsula mentioned that, "Corn is really suffering. Unless rain comes soon, we will be lucky to have corn silage." Another reporter in the central Lower Peninsula said that, "Soil moisture conditions are critical! Most in this area report having to cut the second hay crop only in the hopes that it will produce a third cutting." Field Crops Report Field Crops Dry conditions continued across much of the State. Variable precipitation at the end of the week provided relief to crops in some areas. Corn condition varied depending on the amount of rainfall received. In areas that have received limited amounts of precipitation, the corn crop continued to show visible signs of stress. Soybeans continued to bloom and set pods in some areas. Oat harvest continued in many areas. Alfalfa re-growth continued to be short. Harvest of a second cutting was completed in many areas; a third cutting continued in areas where there was sufficient re-growth. Dry beans continued to bloom. Sugarbeets continued to add growth. Fruit, Vegetable, and Specialty Crops Report Fruit The drought conditions have stressed young trees and newly planted small fruit across the State. Fruit sizing has been hindered in orchards without irrigation Paula Red apple harvest will begin this week. Coddling moth trap catches increased. Blueberry harvest continued; Bluecrop, Jersey, and Elliot were the principal varieties being picked. Red Haven, PF12A, Starfire, Blazingstar, and Redstar peach varieties were harvested. Fall raspberry harvest began Tart cherry harvesting continued in the northwest. Most growers are done. Grape veraison began in early ripening varieties. Grape berry moth numbers rose. Pears were 2.5 inches in diameter in the southeast. Plums began coloring. Vegetables Warmer temperatures continued to stress crops. Carrots continued to slowly progress. Harvest was slightly delayed as growers irrigated to help in sizing. Celery harvest continued with favorable development. Cabbage and lettuce harvest continued. Cabbage continued normal development at various growth stages where irrigation was available. Potato harvest continued for farmer's markets. Potato Leafhopper numbers remained low with very little disease pressure. Sweet corn harvest continued with good quality. Fields were maturing at a rapid pace with the extended warm weather. Earworm and corn borer numbers remained low for the season. Watermelons were being harvested with good size. Cantaloup harvest continued. Cucumber harvest continued. The relatively few non-irrigated fields were in a stressed condition. Bacterial wilt and Downy Mildew were not a problem for most fields. Zucchini and summer squash harvest continued with no indications of viruses. Pumpkins were showing fruit in most fields. Powdery mildew was reported in some areas. Winter squash was affected by the high temperatures resulting in extreme daytime wilting. There were no signs of disease other than some angular leaf spot. Tomato and pepper harvest continued with reports of blossom end rot in some fields. Onions, leeks, and red beets continued with favorable development. Many fields were being harvested. Snap beans were in good condition, even in non-irrigated fields.
