The difficulty in using ammonia or vinegar is that you need to see them to spray them. This means either foregoing a little sleep in the evening, getting up early in the morning or making traps. My preference is the traps. Since slugs don t like hot dry conditions, they usually hide when the sun warms up. Favorite places to hide include under a nice cool rock, board or mulch.
Some people place two boards on top of each other with a small stick between.
Many different problems can result in very similar symptoms in plants. For example, sun scorch, fungal disease, bacterial disease, nutrient deficiency may all result in interveinal chlorosis and later necrosis. It is very important to take additional steps to determine the primary cause. Secondary fungi could move into almost any damaged tissue so confirmation steps are critical for an effective pest and disease management strategy. To diagnose foliar nematodes, first, realize that you can see them.
