Hemp, widely recognized as a disease-resistant plant, is now under scrutiny as researchers investigate the potential threat of certain pathogens reaching problematic levels in field plantings. The consequences of significant disease outbreaks in hemp fields can range from premature leaf drop and bud decay to dieback, decline, and even plant mortality. To combat this emerging challenge, implementing a robust sanitation program can prove instrumental in reducing disease incidence and the reliance on chemical controls, which are limited for hemp growers. Furthermore, practicing good sanitation techniques can enhance the effectiveness of other cultural strategies for disease management.
Sanitation practices play a pivotal role in maintaining field health. It involves the removal of diseased plant tissues to prevent further spread of pathogens. Affected branches should be pruned several inches below the point of infection, preferably at intersecting branches. Severely infected plants and those afflicted with untreatable diseases like root rots and vascular wilts should be discarded entirely. Fallen leaves, prunings, and culled plants must be promptly and appropriately disposed of, either by burying, burning, or removing them from the area, while avoiding composting of diseased materials.
To further bolster field hygiene, fallen leaves can be plowed under to facilitate the breakdown of leaf tissue. However, it's essential to note that woody stems do not readily decay and should be completely removed from the fields. Additionally, diligent efforts should be made to control weeds and eliminate volunteer plants, as they serve as alternate hosts for diseases and contribute to their spread.
By adhering to these sanitation practices, hemp cultivators can proactively reduce disease risks, promote crop health, and enhance the sustainability of their operations. Small-scale plantings can refer to resources such as the Kentucky Hemp Disease Website for further guidance on hemp field sanitation, while the Plant Pathology Publication Webpage provides additional valuable information in this regard. Emphasizing sanitation as an integral component of hemp farming will contribute to the long-term success and resilience of this burgeoning industry.
