mi-crop-weather State Michigan Crop Weather Released September 11, 2006 Week Ending Date September 10, 2006 Issue MI-CW3606 Agricultural Summary Rain Returns Six days were suitable for fieldwork during the week ending September 10, according to the USDA, NASS, Michigan Field Office. Precipitation amounts ranged from 0.19 in the central Lower Peninsula to 0.60 inches in the western Upper Peninsula. Average temperatures ranged from 3 degrees below normal in the east central and southwest Lower Peninsula to normal in the eastern Upper Peninsula. Scattered showers helped late maturing crops but did not hamper harvest. Some areas were still in dry conditions. A farmer in the southwest region mentioned that, "Six-tenths of an inch of rain on September 5. That was enough to help complete the growing season without creating massive amounts of mud." A farmer in the northwest said that, "The corn is as good as it's going to get. A walk through the field showed most corn did not fill well, ears showed poor pollination, and only about 30 percent looked normal." Field Crops Report Field Crops Precipitation fell over the weekend and should help improve late maturing crops. Corn continued to mature, with many fields in the black layer stage. Silage harvest remained strong. Soybean leaves continued turning. In some soybean fields, plants started to drop their leaves. Third and fourth cuttings of hay were slowed due to cool temperatures. Potato harvest continued. Dry bean harvest was in full swing. Sugarbeet harvest will begin soon. Spread of cercospera leafspot has been slowed due to cool night temperatures. Fruit, Vegetable, and Specialty Crops Report Fruit Insect pressure in fruit decreased in the south where coddling moth, Japanese beetle, and apple maggot catches were low. Sooty blotch and flyspeck became more common and some growers reported pinpoint apple scab in the south. Coddling moth flight increased over the last two weeks and obliquebanded leafroller catches were high in the northwest. Apple harvest of early varieties was underway across the State. In the southwest, Gala and McIntosh growers harvested fruit not damaged from the August 23 storms. Ginger Gold apples were harvested in the northwest. Peach harvest was underway in the west central and nearing completion in the south. Encore and other late varieties were being harvested in the southwest. The southeast had extensive leaf drop due to bacterial spot infected fruit as well as Japanese beetle feeding. Plum harvest continued in the southwest and southeast. Brown rot was a problem. Sweet and tart cherry blocks across the State were defoliated by cherry leaf spot. Cherry fruit flies were caught in high numbers in the northwest. Pear harvest continued in the southwest. Pear and blueberry harvest was nearly complete in the southeast. In the southwest, harvest continued for Elliot and Jersey blueberry varieties. Many producers in the southwest sustained crop loss due to the August 23 storm, resulting in a shift of harvested fruit for processing. Downy mildew continued to be a widespread problem for Michigan grape producers. Harvest began for Concord types in the southeast and Niagara in the southwest. Marquis table grapes were ready for first picking in the northwest. Sphinx moth larvae were large and their feeding injury was apparent in the northwest. Vegetables Vegetable crops throughout the State continued to be harvested. Pumpkins were sizing well. Celery and onion harvest continued in the southwest. Pepper harvest continued with the presence of aphids and very small corn borer larvae in some crops in the southeast. Harvest of summer squash slowed. Watermelon harvest progressed with good size and quality in some areas. Winter squash harvest began in light amounts in the southwest. Sweet corn harvest also continued with noticeable corn borer and earworm damage in the southwest. Tomato harvest for processing and fresh market continued with good quality.
