I have Knock out Roses, Indian Hawthorns and Holly's in my shrub beds. Can this product be used as a drench? If so what is the rate?
Prime Source Chlorothalonil 82.5DF Select is not labeled to be applied as a drench. It offers a protective barrier so it should be applied directly to foliage. The foliar rate will vary depending on what you are treating. Please consult the product label to find the appropriate rate for your needs.
