Weather review
Over the last month, most areas of the state have seen average temperatures for this time of year and lower than normal temperatures over the last week. Accumulated precipitation is variable depending upon location with above average precipitation across much of mid- Michigan. Southern Michigan had a chance to dry out over the last week although it won’t last long!
For the Lower Peninsula, growing degree days (base 50 degrees Fahrenheit) range from 1,500 in northwest Michigan to nearly 2,200 in southern Michigan. This equates to a couple days to 14 days ahead of normal for most of the Lower Peninsula. Most areas of the Upper Peninsula are below normal or closer to average.
Looking ahead
Medium range guidance suggests a chance for slightly below normal temperatures Aug. 18-22. The 6-10 day forecast suggests near normal precipitation.

Stage of production/physiology
Hops across Michigan are in Growth Stage 6: Flowering, Growth Stage 7: Development of cones, and Growth Stage 8: Maturity of cones, depending upon growing location and cultivar.
In the field
Growers are harvesting in southern Michigan and preparing for harvest in northern parts of the state.
Sincere thanks to the Michigan hop producers who provided timely input for the Michigan Hop Crop Report.

Become a licensed pesticide applicator
All growers utilizing pesticide can benefit from getting their license, even if not legally required. Understanding pesticides and the associated regulations can help growers protect themselves, others, and the environment. Michigan pesticide applicator licenses are administered by the Michigan Department of Agriculture and Rural Development. You can read all about the process by visiting the Pesticide FAQ webpage. Michigan State University offers a number of resources to assist people pursuing their license, including an online study/continuing ed course and study manuals.
