Question Where do I purchase malathion or Hordicultural oil?
I have my sago palms for years and now they are starting to dry-up and die!
Answer Malathion and Horticultural oil can be found at your local nursery.
Oil sprays should be your first response; if used early and often this may be enough to control or eliminate the insect on your plants. Parafinnic oils or ultrafine horticultural oils such as Sunspray™ as well as fish oils – not fish emulsion - such as Organocide™ can to give effective control. Malathion™ mixed with oil has given good, low cost control but is hard on beneficial insects. Apply oil sprays to the entire plant at 10 days to 2 week intervals throughout the summer. Occasionally wash the plant with a strong stream of water to remove oily buildup and layers of dead – and living – scale insects. This cleanup also helps keeps the plant looking good. Newer chemistry includes Distance™ or pyriproxyfen, an insect growth regulator formulated to be sprayed onto the foliage. Safari™ or dinotefuran is a systemic control that is water soluble and can be either drenched or applied twice a year to foliage to give excellent control.
