That really depends on what pest you are dealing with. An Insecticide spray will kill insects. A Miitacide will kill mites. A Fungicide will kill various funguses that attack rose foliage. These are all grouped into the larger group called Pesticides. Once you identify the pest, you can go about getting the product needed to deal with it. Read the various product labels carefully and find one that "both" lists the problem pest AND states that it will eliminate such pest(s).
