Mix Bobbex Rose Deer and Insect Concentrated Spray with water into our 48 oz. ready-to-use reusable pump sprayer or any other clean pressurized sprayer. Spring & summer mixing ratio: dilute 1 oz. of Concentrate to every 8 oz. of water. (14 oz. of Concentrate makes 1 gallon of diluted Bobbex Rose Deer and Insect spray). During the spring and summer, when the plant is growing quickly and new growth is unprotected, spray every 10 to 14 days or every 2 inches of new plant growth. Fall & winter mixing ratio: dilute 1 oz. of Concentrate to every 5 oz. of water. (21 oz. of Concentrate makes 1 gallon of diluted Bobbex Rose Deer and Insect spray). For fall and winter protection, spray every 4-8 weeks depending on the severity of your deer predation problem. Allow for 6 hours of drying time before any predicted rain or scheduled watering of your plants. Spray the dry plant surface including leaf and stem, sufficiently to coat to both sides. Use diluted mixture within 5 days.
