There were 5.4 days suitable for fieldwork in Michigan during the week ending August 3, according to the USDA, NASS, Great Lakes Region. Although sporadic storms and hail damage were reported in the central part of the state, cool and dry weather in most regions has been a challenge to crop development while providing favorable conditions for wheat and hay harvest. Field activities for the week included: harvesting wheat and hay, spraying, spreading manure, and fall tillage.
Corn and soybeans were starting to show signs of drought-induced stress, winter wheat harvest was nearing completion, oats harvest was underway, and alfalfa hay third cutting commenced. Corn condition was 77% good to excellent compared to 69% last year. Soybeans condition was 65% good to excellent compared to 72% last year.
Apple fruit ranged from 2 to 3 inches in the southwest. Some summer varieties like Transparent and Lodi were picked in the southeast. Peach harvest continued, as Garnet Beauty and Summer Serenade varieties ripened. Pears were 1.5 inches or more in the south. The sweet cherry harvest continued in the northwest. The quality has been good despite frequent rains.
Tart cherry harvest was about three-fourths done in the west central area. The northwest harvest was underway. Japanese plum harvest continued, and European plum harvest began. Clusters were filling on Niagara and Concord grapes. While vinifera wine grape output will be down substantially, many vineyards of hybrids have full crops. Summer raspberry harvest wound down.
The harvest of Jersey blueberries began. Demand for pick your own has been strong. The number of insecticide applications against Spotted Wing Drosophila (SWD) in berries has been lower than last year. Also, there have been no reports of fruit rejected at processors due to fruit larvae.
Tomato and pepper harvest continued in the southwest region although cooler temperatures have slowed crop development. Melon, zucchini, and squash harvest continued in the southeast region. Cucumber harvest continued in the region but has slowed due to low temperatures. Sweet corn harvest has begun in the northwest and pumpkins have started to develop fruit.
Onions are sizing well in the Bay area although heavy disease pressure remains a concern. Squash and zucchini are being replanted in the Bay area for a second harvest. Carrot growth in the west central region continues to make progress despite heavy disease pressure. Vine crops across most of the State have experienced pollination problems attributed to below average temperatures. Generally, disease pressure remains high in vegetable crops and many areas need precipitation.
