Orchids viruses
Unfortunately, viruses are very difficult to identify. The most common symptoms are deformed flowers, streaking foliage, veinal discoloration, yellowing, stunted growth and death. Viruses cannot be cured. Any orchid with a virus should be destroyed to prevent
its spread to other plants. Viruses may be prevented by keeping the growing area clean, using sterile pots and growing media, sterilizing all
pruning instruments and keeping your plants free of aphids, since they can transmit viruses.
Orchids pest control
Integrated Pest Management (IPM) is a program designed to minimize (not eliminate) the use of chemical controls in the environment. IPM is not only a benefit to the environment, but it is also economically beneficial, since chemical pesticides and fungicides are often expensive. The success of IPM relies on frequent monitoring and inspection of plants. By carefully monitoring and inspecting, most pests and diseases can be identified at a manageable stage; therefore, the need for potent chemicals is eliminated or reduced. Once a pest or disease has been identified, the first response is to handpick the insect, or cut away diseased tissue. Traps, soaps and oils are the second alternative. The last resort recommended would be the use of botanical pesticides/ fungicides and then chemical pesticides/fungicides.
