How To Treat Orchids With Orthene?

Orthene spray is a highly systemic insecticide that is recommended for use on orchids in greenhouses at a rate of lttpg. (rounded). It does not leave any unsightly residue and is not suitable for use on ferns or palms. To treat scale, use a Q tip dipped in isopropyl alcohol or a toothbrush dipped in a pesticide like Malathion, Orthene, Summer Oil, or Safer Soap.

Orthene 75 is not labeled for use on orchids, but some growers have reported using it to prevent thrip damage, aphids, and ants. The classic prescription is to treat every seven to 10 days for three treatments, alternating insecticides. For example, you might choose to use Orthene and Malathion.

A preventative spraying of Orthene 75, either wettable powder or aerosol, on maturing flower buds will prevent thrip damage, aphids, and ants. If insects are present, Orthene controls a wide range of insects, especially aphids on certain ornamental flowers, roses, shrubs, and trees. The active ingredient is acephate, which is absorbed by plant roots.

To use Orthene spray, follow the directions on the label and spray from at least a foot away from the flowers. If using a sprayer to water and fertilize your orchids, direct the sprayer to the potting media surface to wet the roots. If using Siphonex or other insecticides, use 0.2 ounces of Orthene 97 Spray Insecticide in one gallon of water.

To treat infected plant parts, a fungicide should be applied to protect the remaining healthy tissue. Cinnamon is an excellent fungicide, and ground cinnamon can be applied directly to the exposed area. First Rays Orchids recommends mixing cinnamon with casein-based glue or cooking oil to form a waterproof paste. StopRot, a poultice developed specifically for orchids, contains a Bordeaux mixture in lanolin, which has fungicidal properties. Cover all exposed areas with the fungicide or sealant to prevent new infections from entering.

Drenching the affected plant with fungicide is also recommended, with protectant fungicides like Truban or Terrazole recommended for early diagnosis. Systemic fungicides like Aliette or Subdue are more effective for advanced cases. Some growers recommend Captan, Dithane M-45, and Physan 20 for control of black rot. To protect seedlings from damping off, water them with the fungicide of choice and treat them with a preventive fungicide at two-week intervals.
