Michigan hop crop report week of June 6, 2024

EmailHops are ahead of schedule, but a short cool down is on the horizon.
Weather review
Temperatures during March through May were higher than average across Michigan. Although, over the last week temperatures have been closer to normal. Precipitation in early March through the end of May has been variable across the state with slightly above average accumulation in the eastern Upper Peninsula, northern and southwest Michigan and below average accumulation across central Michigan. Over the last week, the trend has continued with greater than average precipitation for most areas of the northern Lower Peninsula and the Thumb and less than average precipitation in the western Upper Peninsula and south-central Michigan.
In terms of growing degree-day (GDD) accumulation, most areas of the state are still several days ahead of average.
Looking ahead
Medium range guidance suggests cooler than normal temperatures over the next week prior to a return to above average temperatures the last two weeks of June. The 6–10 day precipitation outlook suggests near normal precipitation.

Stage of production/physiology
Hops across Michigan are in Principal Growth Stage 1: Leaf Development (from re-growth after burn back) and entering Growth Stage 2: Formation of Side Shoots and 3: Elongation of Bines depending upon growing location.
In the field
Across Michigan, hops have been trained and are climbing their way up the coir. Growers are actively fertilizing, irrigating and applying plant protection products for disease control. Leafhoppers that came in with the first storms out of the south have been controlled. Plant growth is about a week ahead of normal depending on the location around the state.

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.
