Don't use anything right now and give us more information. It sounds like you are trying to cure symptoms of a larger underlying environmental or structural problem that should be addressed first, one that likely involves water, drainage, sun exposure or airflow. Please provide a description of your growing space, your soil type, what you're trying to grow and how you've gone about it so far. Photos please, if possible.
I couldn't find a product called Garden Organics. Is there a brand attached to that? As for Wondercide, are you trying to control fleas and ticks? It doesn't appear to be a product designed specifically for plant/garden use.
So, provide more information from you, and we'll see what's going on!
