Serenade Garden provides protection against a broad spectrum of the most common fungal and bacterial garden diseases, yet is completely non-toxic to bees and beneficial insects. It is so safe you can confidently harvest and eat fruits and vegetables the very same day they are treated. Unlike sulfur-based disease control products, Serenade Garden is non-irritating to skin and lungs. Also, unlike neem oil based products that can injure plant foliage, there are no weather or timing restrictions limiting its application.
