Fungicide Practices at Arkansas Forest Nurseries
The treatment of fungus in the nursery is one of our most important problems. In maintaining a microclimate suitable for germination and growth of germinates, we are creating an ideal situation for fungus damage. Our main damages are pre- and post-emergence dampingoff and root rot. (Too often pre-emergence damping-off is attributed to the quality of the seed). We try to control the environmental conditions of our nurseries by: 1. Using sawdust and fertilizer to keep the pH of our soil below 5.8, which we know is very high for pine trees. 2. Planting in early spring to avoid high temperatures (over 85°) during germination and until secondary needles are formed. 3. Keeping our nitrogen content low during this time. No legumes for soil building just prior to planting. 4. Keeping the beds as dry as we dare by irrigating early in the day so the ground and seedlings will dry considerably before nightfall.
