Insects

1. ROSE MIDGE
• Ortho-Klor - Promising control in test gardens
• Orthene - Controls small infestations
2. APHIDS AND MOST OTHER INSECTS
• Orthene - Probably most effective all-over insecticide. New formulation doesn't have that same strong smell
• Malathion (50 Plus) - Old stand by, use only when necessary
• Diazinon - Broad-spectrum insecticide, being removed from market
• Insecticidal Soap - Safers, spot control only
• Bug-Stop - Spectricide, Pyrethrum based, Broad-spectrum (contains cyflutherin)
3. SPIDER MITES
• Avid - 2 applications at  4 - 7 day intervals. Very effective, very expensive
• Isotox IV - Also for insects, use as needed
4. THRIPS
• Orthene - 2 - 3 day intervals,  mist blooms as needed

Sprayer Types:

1. COMPRESSION TYPE -  Two common types.  One uses garden hose to pressurize, the other uses  hand pump.  Both are good and efficient.  Add spray material to measured amount of water.
2. HOSE-END TYPE - Attaches to end of garden hose.  Uses venturi to siphon spray material from bottle.  Need back-flow prevention devise on water line.  Not accurate or efficient. Use only for liquid fertilizers.
