Harvest Techniques for Hops (Humulus lupulus)

Hop cone formation. Left: newly formed hop burr. Right: mature hop cone.

Hops (Humulus lupulus) are perennial plants commonly harvested for their mature strobiles, also referred to as cones, which are primarily dried and used as a bittering agent and preservative in beer production. The two primary factors of harvest timing and harvest method can have large impacts on the quality and economics of the finished product. The decision of when and how to harvest is important and should rely upon growing-region-specific environmental conditions, physical observations of the cones, and the wants and needs of the individual producer. This new 4-page publication of the UF/IFAS Environmental Horticulture Department describes the primary methods used in hop harvesting, including field, indoor, and machine harvesting.

Population declines among bees, butterflies, and other pollinator insects are very worrying because 70% of the world’s food crop production depends upon these tiny insect workers. Fortunately, ninety million US households have yards, landscapes, or gardens that can enhance pollinator habitat and health. Consumers’ actions can drastically impact pollinator insects and even help them to recover. This 5-page fact sheet written by Hayk Khachatryan and Alicia Rihn and published by the UF Department of Food and Resource Economics, October 2016, describes a new UF/IFAS study of consumers’ actions and perceptions as they considered ornamental plants that benefit pollinators. It covers consumers’ current actions to aid pollinators, their interest in purchasing plants to help pollinators, and their perceptions about plant availability, and it describes strategies for merchants and producers to cater to consumer preferences for in-store communications/promotions and help them to find and purchase plants that aid pollinator insects.

Nurseries are a vital part of the citrus industry in Florida, providing growers with trees for replanting and expanding citrus groves. As part of the response to citrus greening and canker disease in the industry, nursery-aimed regulations were set in place to try to guarantee the production of trees “free of virus or other graft transmittable diseases” in plant nurseries. The new regulations resulted in an important shift for producers from traditional open field groves to greenhouses. This 4-page fact sheet describes an experiment performed at the UF/IFAS Mid-Florida REC in Apopka to test the profitability of different inputs in citrus-producing greenhouse nurseries and provides recommendations that will be useful for the whole citrus-tree-producing sector.

Consumers' Response to "Neonic-Free" and Other Insect Pollinator Promotions on Ornamental Plants

Pollinator insects are essential to world food crop production, the economy, and the environment. Neonicotinoid (neonic) insecticides are facing intense backlash from environmental groups because the systemic protection they provide throughout the plant, including the pollen and nectar, may be injuring pollinator insects and causing their population decline. But many nursery and greenhouse growers use neonic-based pesticide control measures because they are effective, inexpensive, and cause less environmental damage than other insecticides. The increased publicity may influence consumer demand and preferences but very few studies have investigated consumer responses to neonic-free labels, and evidence suggests that many consumers have little knowledge or awareness of the issue. This 3-page fact sheet describes the results of a the study investigating how consumers’ awareness of neonic insecticides influenced their preferences and purchasing behavior for plants and exploring the marketing potential of using alternate pollinator promotions (besides neonic-free) in garden center retail outlets.

Consumer Perceptions of Lawn Fertilizer Brands

Widespread urbanization in the United States has increased the number of lawns. A healthy lawn provides many benefits, including urban heat dissipation, water quality protection, erosion control, carbon sequestration, community safety, aesthetics, and property value growth. Many homeowners maintain their healthy lawns by applying fertilizers throughout the growing season, but excess fertilizer runoff and leaching have received much attention recently because of waterway pollution and algae blooms, leading many states to place restrictions on what chemicals can be used in lawn fertilizers.

Consumers’ increased environmental awareness creates a niche opportunity for the fertilizer industry to promote environmentally friendly lawn fertilizers, but in order to effectively exploit it, industry stakeholders must understand consumer purchasing behavior before expending labor, time, and money creating products for sale. The following 3-page report written by Hayk Khachatryan, Alicia Rihn, and Michael Dukes and published by the Food and Resource Economics Department covers research methodology and the existing brand awareness and selection of consumers in the lawn fertilizer industry. It also discusses homeowners’ preferences for certain fertilizer attributes. Consumer awareness, selection, and attribute preferences indicate existing behavior, and understanding existing behavior assists in the development of effective marketing programs, promotional strategies, and policies.
