Abstract

Cold atmospheric plasmas (CAPs) have been shown to have disinfectant properties in human and animal health systems, providing surface and sub-surface activity while leaving healthy tissue undamaged. Very recently, CAPs have been shown to reduce certain plant diseases, and to modify seed and seedling behaviour, altering seed coat properties and water uptake, resulting in improved seedling vigour and, in some cases, improved crop yield. Many horticultural crops are adversely affected by seed-borne diseases which are difficult to control with standard fungicidal products. In broad-acre arable crops, while seed-borne diseases can usually be effectively controlled, there are many establishment problems, primarily associated with lack of moisture, which result in either crop loss, or more usually sub-optimal plant populations, poor growth and lower final yields. This feasibility study will focus on understanding how CAPs could be used to condition seed and overcome some of these problems. Contrasting seed types and problems will be addressed, to include a) control of seed-borne disease in small seeded vegetables (celery, onion, lettuce) b) promotion of germination and vigour in large seeded (maize) and small seeded (oilseed rape) field crops, and evaluation of crop performance. The feasibility study will inform the potential for a novel, easy to use, non-chemical technique for improving crop performance, and create a commercial opportunity for the development of safe and effective plasma generating units.

Summary

Cold atmospheric plasmas (CAPs) have been shown to have disinfectant properties in human and animal health systems, providing surface and sub-surface activity while leaving healthy tissue undamaged. Very recently, CAPs have been shown to reduce certain plant diseases, and to modify seed and seedling behaviour, altering seed coat properties and water uptake, resulting in improved seedling vigour and, in some cases, improved crop yield.

In broad-acre arable crops, while seed-borne diseases can usually be effectively controlled, there are many establishment problems, primarily associated with lack of moisture, which result in either crop loss, or more usually sub-optimal plant populations, poor growth and lower final yields.

Impact Summary

The impact of this research will be on a) producers and growers b) advisors and agronomists. The research output will be an appraisal of the benefits of cold atmospheric plasma treatments on seed. While further research after the feasibility study will be needed, the impacts would be a new seed conditioning system which could be applied, according to specific growing circumstances, at the point of planting, by producers. There would be potential for reducing losses in the supply chain through waste reduction (eg celery heads infected with Septoria, a seed-borne pathogen, are discarded) and benefits of increased crop productivity with better and more uniform establishment. Rapid establishment is a key factor in oilseed rape production, and would contribute to reducing exposure to cabbage stem flea beetle damage in the absence of neonicotenoid seed treatments. Agronomists and advisors would need to acquire new knowledge about when and how to use plasmas, and new supply chains for appropriate gases would need to be established. The technology would also impact on the crop protection industry, where it would complement existing treatments rather than replace them. Though this study is focused on crop production, cold plasmas are already being investigated as disinfection strategies in food processing and packing systems because of their antimicrobial activity at low temperatures. Potentially, this research may generate new information on antimicrobial effects which could be applied in the treatment of food, and for the eradication of human pathogens on plants (eg in sprouting seeds, pre-packed salads etc)
