INSECTICIDAL SOAP SPRAYS : these are made from potassium salts of fatty acids. They control pests that have soft bodies, such as aphids when they are in their young stage.
HORTICULTURAL OILS: are very refined oils from plants that will smother insects, their eggs, and disease spores. Some of this oil type can be used during the growing season, and others are used as dormant sprays. Do not use if the weather is hot (80+F) as it may burn the leaves.
BAKING SODA: when mixed with water, this is an easy home remedy for powdery mildew and black spot. You may also use commercial products that contain potassium bicarbonate.
NEEM: this is a botanical insecticide that comes from the bark of a tree native to India. Neem repels the pests and makes them stop feeding. It's not as effective during hot weather.
PYRETHRUM : a derivative from a chrysanthemum plant. There is a more concentrated form called Pyrethrin. Both are highly toxic to insects. There is also a more common Pyrethroid product that are made from a synthetic chemical. They are more toxic and linger in the environment more than Pyrethrum and Pyrethrin.
A FINAL NOTE: consider synthetic pesticides only as a last resort. Many are toxic to humans, animals, and of course to all beneficial insects. They should never be used on edible plants such as vegetables. Do not use on roses near a vegatable garden.
Synthetic products can be safe and highly effective if used correctly. Wear protective gear and follow label instructions carefully when using rose diseases treatment products.
