Crop Technologies for Hop Growers

Commercial hop production is a growing industry. Craft beer brewing has surged dramatically over the last three decades, and all of those small breweries across the United States are now looking for local hop growers to supply them.1

What Are Hops? More about the precious beer-makers crop

Hops, or hop cones, are flowers that grow on an herbaceous perennial known as Humulus lupulus.2 As any experienced beer-maker knows, hops are a critical feature of the brewing process — they provide the characteristic bitterness, flavor and aroma of beer, in addition to their antimicrobial properties.3-4 Hops grow in many different varieties that affect the taste and composition of each particular brew.

If you are a hop grower, you're not alone. In fact, the United States is one of the leading countries in hop production.

Challenges for Hop Growers

As a hop grower, your job is to grow hops for beer. Hop crop production can take the form of conventionally grown raw hops or organically grown hops. If growing high-quality hops is your goal, you will overcome a variety of challenges, including growing hops that are pest-resistant and achieving quality growth with a limited supply of nitrogen.5

Other challenges you may face can include weeds and pests like two-spotted spider mites, which can quickly lay waste to your complete hop crop.6 Fortunately, Kemin provides high-quality solutions for growing hops successfully in all conditions and situations, particularly when it comes to the issue of spider mites.

The Problem of Two-Spotted Spider Mites for Hop Growers

One of the hop grower’s greatest enemies is the two-spotted spider mite.6 This widespread crop pest loves the hot and dry conditions often found in hop fields. They cover your crops with an unsightly white webbing, which protects them from predators and pesticides. Then, they feed on the liquid inside plant cells, doing dramatic damage to the hop plant and cones, reducing yields and negatively affecting hop quality.7-8

Spider mites are the bane of many crop growers, including hops cultivators, for a number of reasons. Conventionally-grown raw hops tend to be inadequate when it comes to shaking off pesticide residue. A study by Hengel and Shibamoto (2002)9 found relatively high levels of pesticide residue on hops treated with seven common commercial pesticides. What’s worse, spider mites tend to be highly resistant to such pesticides anyway.
