Evaluating the sensitive of SWD monitoring tools in blackberries
Evaluate two types of monitoring traps for the invasive spotted-wing drosophila, a vinegar fly that attacks small fruit while it is still ripening on the plant. We will use the commercial Scentry SWD monitoring trap, which uses a jelly-pouch lure suspended above a 25% apple cider vinegar drowning solution, and a newer trece SWD monitoring trap, which uses a lure to capture adults directly on a sticky trap, without drowning solution. We will monitor SWD activity using both trap types during the summer of 2023 and at the end of the season, compare date of first detection and the total number of adults detected with each trap type. This information will help inform small fruit growers about the most effective and easy-to-use monitoring tools for SWD.

Developing pollinator-friendly lures to monitor cucumber beetles in cucurbit production
Striped cucumber beetle quickly aggregates in a wide range of cucurbit hosts including watermelon, squash, cucumber, and pumpkin where than can transmit lethal diseases. Existing management practices rely heavily on insecticide use, which could have negative non-target effects on honeybees and other pollinators that increase yield. This study aims to develop lures that attract cucumber beetles without distracting pollinators.

Spider mite outbreak on watermelon
Pests are a concern for watermelon growers and pesticides are routinary applied in commercial fields to control them. However, overly aggressive insect management could trigger spider mite outbreaks. IPM programs based on thresholds can minimize secondary pest outbreaks. Additionally, rye is used to protect watermelon seedlings from sand blasting damage but growers believe rye can also act as a bride to the crop for spider mites, and they may spray more unnecessary miticides. We hypothesize that intensive insecticide programs and rye cover crop can facilitate spider mite outbreaks, whilst using an IPM program for insect control and no rye would prevent spider mites from outbreak with no miticide applications need.
Contact: Ian Kaplan, Zeus Mateos
Flowering cover crops on watermelon
Most watermelon producers use rye as an intercrop that functions primarily as a wind-break to prevent sandblasting damage to vulnerable, newly-transplanted seedlings. However, rye may act as a 'green bridge' for critical pests (e.g., spider mites) leading to preventative and expensive miticide applications. Also, rye is a grass with limited resources (e.g., nectar, pollen) to sustain beds and/or natural enemies. This project will test flowering cover crops that are both non-hosts for mites and non-crop food resources to boost beneficial insects.

Bee and butterfly forage garden
In an effort to supply a dedicated area of pesticide free, diverse, and season-long forage for a range of pollinating insects used in research and extension, an area of Meigs is being "rehabilitated" to remove poison ivy, brambles, and other low-value (for pollinators) species and replace with a mix of annual and perennial wildflowers and forbs that are native to the area.

USDA AFRI Grant – Taking the next step as a small and medium-sized farm: Understanding the integration of production, food safety, and profitability
To improve the profitability of small and medium-sized vegetable farms by
developing a research-based extension program that increases strategic soil to market
decision making by farmers titled Soil to Market Decision Making. The project has three
objectives: 1) improve farm planning practices of small and medium-sized vegetable farmers;
2) increase farm production capacity and produce quality by enhancing farmers’ ability to
manage soil health while using appropriate genetic materials; and 3) increase farmer
profitability by enhance.

Determine optimal roll time of sunnhemp for cover crop based reduced tillage (CCRT) vegetable systems
Conserving soil resources and improving soil health are on the forefront of farmers. Policy makers, and even consumers minds. Reduced tillage is challenging for vegetable production systems due to the need to prepare beds and cultivate. In addition, the short season nature of many vegetable crops often results in nitrogen asynchrony from cover crop decomposition and cash crop uptake. Previous research investigating legumes for reduced tillage systems have had varying results. New cover crop options for reduced tillage vegetable systems production are needed. This project aims to evaluate sunnhemp for a reduced tillage vegetable system. Sunnhemp has shown it can provide large quantities of biomass in addition to its upright stature. These both attributes conducive to a cover crop based reduced tillage system. In addition, sunnhemp can provide up to 134kg/ha of N, which could eliminate or reduce N asynchrony issues observed in cereal rye CCRT systems. This project aims to determine the 1. optimal time to roll sunnhemp, 2. measure N release from cover crop residue and estimate cash crop uptake.

Evaluation of in-row spacing effect on weed-suppression in sweet potato organic system
Weed interference is a serious challenge for many sweet potato producers globally. This experiment will help us evaluate the effects of in-row crop spacings on yield of sweet potato and weed suppression. We will also use cultivars a factor, comparing prostrate growth cultivars to upright or bunch-type growth cultivars. We will have our three spacings (20cm,30cm,40com) as our main factor or treatment and cultivars and environment (weed free vs critical weed free period) as sub-factors.
