mi-crop-weather State Michigan Crop Weather Released June 21, 2010 Week Ending Date June 20, 2010 Issue MI-CW2510 Agricultural Summary Rain Returns Five days were suitable for fieldwork during the week ending June 20, according to the USDA, NASS, Michigan Field Office. Precipitation varied from 0.38 inches in the east central Lower Peninsula to 1.54 inches in the southwest Lower Peninsula. Average temperatures ranged from 2 degree above normal in the western Upper Peninsula to 4 degrees above normal in the southeast Lower Peninsula. Where dry, producers were able to finish planting, and got some spraying done. Some thunderstorms passed through central and southern Michigan this week keeping some fields wet. Other activities for the week included hay harvesting. One reporter in east central Michigan stated, "We had comfortable temperatures this week with spits of rain every couple days. Hay has been getting cut and baled, but usually not without getting rained on at least once." Field Crops Report Field Crops Rainy weather continued to hinder many field activities. Wheat headed due to warmer weather conditions. The reports of powdery mildew, Septoria, and Fusarium head blight (scab) continued. The oat and barley crop followed a steady trend toward maturity. A few reports were made about lodging and cereal leaf beetle in the west central region. Alfalfa was in the first or second cutting stage but was delayed due to recent rains. Those that took a first cutting in late May will be ready for a second cutting soon. Potato leafhoppers are a growing concern. Sugarbeets were progressing well, however some fields became water-logged during recent rain showers. Corn continued to progress with some fields entering V8 stage in the southern part of the state. Typical pests such as corn borer, armyworm, and slugs were spotted. Early planted soybean acres look promising. Some acres still need to be planted. Later planted fields were dealing with poor emergence. Weather has caused a delay in spraying which led to weed control issues on corn and soybeans acres. Drybean planting continued. Early planted acres have emerged with a concern of root rot due to wet soils. Fruit, Vegetable, and Specialty Crops Report Fruit Ripening seemed to be two weeks ahead of normal in the southwest, and harvest of some fruit crops began two weeks ahead of normal in the southeast. Apples ranged from fruit size 25 to 27 mm in the northwest to 1.5 to 2 inches in the southwest and southeast. In the west central, the crop was about 15 to 20 percent of full potential. Potato leafhoppers were present in the southwest and southeast. Peaches ranged from fruit size 1.2 to 1.7 inches in the southwest and southeast. The crop was estimated at 60 to 70 percent of the full potential in the west central. European plums were 21 mm in the northwest and 1 inch in diameter and 1.5 inch in length in the southeast and west central. Strawberry harvest has continued in the southwest, southeast, and Grand Rapids areas, and harvest began in the northwest. Sweet cherries were at 17 to 20 mm diameter and began coloring in the northwest; fruit harvest has begun on early varieties in the southwest and southeast. Tart cherries ranged from fruit size 15 mm in the northwest to fruit coloring in the southwest. A high level of cherry leaf spot was found in the southeast and southwest. Pears ranged from 23 mm diameter in the northwest to two inches in diameter in the southwest. In the west central, there was only about 10 percent of full crop potential. Blueberries were at fruit size 13 mm in the southeast, with green fruit in the southwest and Grand Rapids areas. Early varieties began ripening. Fruit is sizing well because of recent rainfall, and there seemed to be a complete crop in most varieties in the Grand Rapids area. Grapes were at first bloom in the northwest; bloom has ended and buckshot stage has begun in the southeast. Summer raspberries were in bloom in the northwest and were coloring in the southwest. Vegetables Warm weather aided the progression of all vegetable crops last week. Asparagus harvest was all but complete with many fields having high weed pressure. Processors in the Oceana County area will soon shut down asparagus processing for 2010. Harvest of yellow squash, zucchini, cabbage, sweet peas, greens, snap beans under tunnels, and radishes continued. Snap beans, in the Macomb county area were in flower. Some potatoes will be at retail locations, in the Macomb area, next week. Sweet corn development continued. Early planted fields began to tassel and had ears. Second plantings of sweet corn went in as conditions permitted. Processing winter squash and pumpkin stands looked good, but there were reports of cucumber beetles in Oceana County. Processing broccoli planting was underway as growers wrapped up plantings of processing zucchini. Celery, carrots, onions, red beets, parsnips, and radishes looked good, except in areas where crops were suffering from excessive water induced stress. The aster leafhopper index indicated a high level of infection in carrot fields. Additionally, tomatoes, peppers, eggplant, melons, vine crops, squash, and pumpkins also looked good and benefitted from the warm, humid temperatures. Tomatoes varied in fruit size from flower and first fruit to 2 inches in diameter. Melons began fruit formation and were running off plastic planting mediums. Cucumber beetle, flea beetle, corn earworms, European corn borers, imported cabbage worm, cabbage loopers, Colorado potato beetle and diamond back moths were active and trapped in varying crops.
