Pest Exclusion Systems for Pest Management in Vegetable Production Across the Southeast

In organic vegetable production, and in situations where farmers are seeking to reduce chemical applications, Integrated Pest Management (IPM) strategies are recommended to exclude pests in both opens fields and in high tunnels. The principles of pest exclusion involve separating the insect pest from the host plant and protecting the crop at a specific growth stage. Careful planning of both materials selected and management design are important to keeping pests out of a cash crop. This bulletin provides data and information from on-farm demonstrations on the use of pest exclusion systems. Pest exclusion systems use shade cloths as a barrier around high tunnels, low tunnels and hoop houses to exclude insect pests.

Organic Control of White Mold in High Tunnels

The fungus Sclerotinia sclerotiorum infects many of the cool-season crops produced in Kentucky. This SARE-funded video presents information on the high tunnel production system most commonly used in Kentucky; the disease cycle of S. sclerotiorum; and two control tactics compatible with national organic standards, solarization and biofumigation.

The Performance of Cover Crops in Minimally Tilled Forage-based Grazing Systems

In a Southern SARE-funded Graduate Student Grant (GS15-152), “Evaluation of Winter Annual Cover Crops Under Multiple Residue Management: Impacts on land management, soil water depletion, and cash crop productivity,” Texas Tech University researchers investigated five cover crops species as potential complements to a warm-season beef-stocker grazing system. The impact of the project was two-fold: Stabilize the soil surface from excessive wind erosion and desiccation; and strengthen rural communities by ensuring the persistence of profitable agriculture in the region.

Integrating Legumes with Grass to Improve Forage-Livestock Systems

In a Southern SARE-funded Research and Education Grant (LS14-261), "Long-term Agroecosystems Research and Adoption in the Texas Southern High Plains -- Phase III," Texas Tech University researchers conducted a steer grazing trial comparing a grass only system to a grass-legume system for animal productivity and water use efficiency.

Innovations in Large-Scale Trap Cropping for Reducing Insect Pests

Trap cropping is a unique pest prevention system that uses insect behavior to deter pest feeding. Benefits of trap cropping not only include effective pest management, but trap crops can also increase biodiversity, conserve natural enemies and reduce wind damage to main crops.

High Tunnel Pest Exclusion System

Insect pests are one of the major problems in organic production systems. Organic IPM practice consists of a three-tiered approach consisting of systems-based practices, mechanical tactics, and biorational insecticides. Mechanical tactics encourage the use of physical barriers for pest exclusion. This bulletin provides preliminary research data and field observations about the success of shade cloths, or high tunnel pest exclusion (HTPE) systems, as a more permanent barrier system around the high tunnels.

Grazing Cover Crops in Cropland

For some producers with extensive experience using cover crops, grazing can be a ‘next step’ in obtaining additional economic value while achieving environmental stewardship.

Soil Management Using Cover Crops in Organically Managed High Tunnels

In southern climates, high tunnels are typically used for season extension in the spring, fall, and winter. In the hot summer months, if no shade cloth is used to cover high tunnels, it can be difficult to grow anything but the most heat tolerant crops, and it can be uncomfortable to work in tunnels due to the heat. This is an excellent time to incorporate a cover crop, between the late spring and early fall crops. Many cover crops species are adapted to hot southern summers and perform well in high tunnels.
