If you only have afew roses just mix up the fungicide in a watering can. Use rubber kitchen dishwashing type gloves. Take the watering can and pour gently on the rose shrubs. Soak the ground underneath. It works as a drench too in that the roses will take it up by the roots. However, without getting fungicide on the leaves, those drenches never work as well as spraying. However, you don't actually have to use a sprayer LOL!
