Improving Peach Production & Marketing in Alabama

Project Leader: Edgar Vinson

Objectives: (1) evaluation of dormancy-breaking products during season of low chill accumulation, (2) effect of Armillaria root rot (ARR) mitigating strategies on the growth and development of peaches, and (3) use of colored plastic mulches to increase plant growth of ‘MP-29’ rootstock, which is resistant to ARR.

Evaluation of Dormancy-Breaking Products: Dormancy- breaking products hydrogen cyanamide and potassium nitrate penetrant and combinations of penetrant with either hydrogen cyanamide or potassium nitrate were sprayed at two different stages of chill accumulation (70% and 90% chilling) in an orchard of ‘Carolina Gold’ peach, which has a requirement of 1,050 chill hours.

Results: Current results showed that the rest-breaking products overall are more effective if more chilling is received and potassium nitrate can be as effective as hydrogen cyanamide in breaking dormancy. This is important because hydrogen cyanamide is the leading chemical means of alleviating dormancy, but it is sometimes not available. The chemical is also caustic and poses a health risk. Potassium nitrate is a natural fertilizer and safer to use.

Nursery, Floriculture & Christmas Tree Support

Alabama Vegetable IPM Program/High Tunnel Pest Exclusion System Demonstrations (2014 to Present)

This project has established a series of permanent pest exclusion demonstrations using 50% shade cloth as a physical barrier around NRCS-funded high tunnels popular among small farmers.

Project Leader: Ayanava Majumdar Number of Farms: 17 field locations

Adoption Rate for Recommendations: Farmers have used 100% of the IPM recommendations that include the use of microbial insecticides and natural enemy conservation tactics beside pest exclusion systems making this a unique participatory research and evaluation effort.

Grant Funded: Grants have offset $8,163 in the cost of materials (shade cloth).

Crop Success Rate: Crops grown exceed $75,300. Supported by many USDA SARE Professional Development Program and Research and Education grants and ADAI Specialty Crops Block Grants.

Sustainable Crops Educational Programs

Project Leader: Kassie Conner

Target Audience: Growers, homeowners, crop advisers, landscape maintenance industry workers, Alabama Extension personnel, state regulatory agencies, federal regulatory agencies.

Issue/Importance: Accurate pest diagnosis is the first and most critical step in any IPM program. Appropriate IPM recommendations can only be provided when a pest has been properly identified. The Auburn University Plant Diagnostic Lab provides Alabama growers with an unbiased identification of plant problems and management recommendations to protect the health and productivity of plants in Alabama’s agricultural and natural ecosystems.

Project Objectives:

  • Resolve issues that arise with growers in Alabama. Issues include plant disease, insect, weed, crop nutrition, environmental, chemical, cultural, and other unpredictable factors. IPM tactics are considered when providing management options for commercial growers. IPM recommendations provided to growers are based on research findings from Alabama and other states in the southeast region.
  • Resistance to insecticides and pest management technologies are becoming an increasing problem in agriculture. As a result, the Commercial Horticulture Team encourages the use of all available pest management strategies to ensure the longevity of our resources. The team increases awareness and adoption of IPM recommendations in a variety of cropping systems; documents pest outbreaks and the efficacy of available IPM tools; and develops sustainable pest management strategies for Alabama growers.


The Auburn University Plant Diagnostic Laboratory processed 11,996 samples during 2021—3,278 of those samples were routine (1,695 plant samples, 1,481 nematode samples, and 102 insect samples). Throughout the year, 1% of clientele are surveyed to determine specific impacts based on recommendations provided through diagnostics. Clients surveyed (n=33) saved an average of $453 per sample by following Extension recommendations. With 3,278 routine plant samples, the laboratory saved clientele $1,484,934. Of the clients surveyed, 96% indicated that they have adopted or plan to adopt the IPM recommendations provided by the laboratory and based on their diagnostics.


In addition to diagnostics preformed, the Sustainable Crops Team published 4 peer-reviewed journal articles and 1 Extension article. The team also conducted 5 proceedings at conferences; developed a learning module for the Farming Basics Course; provided to various groups 14 presentations on disease identification and management; identified 10 first reports for Alabama (6 of which triggered regulatory actions); provided 13 pest alerts for growers and the industry; consulted on 5 regulatory action committees for the Alabama Department of Agriculture and Industries (ADAI); maintained USDA certification for testing of three regulated pathogens of concern in our area to assist USDA, ADAI, and Alabama growers; and assisted in the National Clean Plant Network to provide Alabama citrus growers with clean (disease-free) budwood.
