Quick Answer
To handle fungal infections in saved seeds, inspect seeds for visible mold, store them in a dry and well-ventilated area, and consider using a seed dryer to ensure optimal moisture levels. Implementing proper seed storage and handling techniques can prevent fungal growth. Isolate seeds from potential fungal sources.
Preventing Fungal Growth
Fungal infections in saved seeds can be prevented by storing them in a dry environment with low humidity. The ideal storage conditions for seeds are between 5-15% relative humidity, which can be achieved by using a desiccant or a sealed container with a silica gel packet. Store seeds away from direct sunlight, heat sources, and potential moisture sources such as pet food or dirty laundry.
Inspecting and Identifying Fungal Infections
Regularly inspect seeds for signs of fungal growth, such as visible mold, white powdery patches, or a sour or musty odor. If you notice any of these signs, remove the infected seeds from the storage container and properly dispose of them to prevent the spread of the fungal infection. In some cases, fungal infections can be identified by performing a visual inspection under a microscope.
Seed Isolation and Viability
To maintain the viability of your saved seeds, maintain an isolation distance of at least 10-15 feet (3-4.5 meters) from potential fungal sources, such as infected plants or compost piles. This will minimize the risk of cross-contamination and ensure the health of your seeds. Regularly test the viability of your seeds by performing a simple germination test, which involves soaking the seeds in water for 24 hours and then planting them in a controlled environment.
