How to preview lilac fungal disease
NDSU Extension says preventive fungicide should be applied now because the fungus survives winter on infected leaves and can defoliate lilacs again.
- Don Kinzler, NDSU Extension-Cass County agent, advises applying preventative fungicides for lilac shrubs now as the fungal disease begins infecting plants early in spring when leaves expand.
- High levels of inoculum survive winter on last year's infected, fallen leaves, creating conditions ripe for disease recurrence if weather conditions are favorable during spring.
- Products listed for control include copper fungicides and those containing chlorothalonil, such as Daconil, or propiconazole found in InFuse, though Label directions must be followed closely.
- Gardeners facing Blossom end rot on tomatoes should maintain consistent soil moisture using 3 to 6 inches of straw, compost, or untreated dry grass clippings as mulch.
- While no tomato varieties are immune, cultivars like Big Beef, Celebrity, and the Mountain series are less prone to Blossom end rot, offering gardeners resistant options for future planting.
