1) Learn to identify physiological disorders which are caused by poor culture. Some examples of this are; sunburn; over or under watering; leaf-tip dieback; salt or wind damage and temperature stress. Spraying of chemicals will not help, but may harm the orchids more.
2) Diseases in orchids: For a disease to occur the pathogen must be present in an infectious stage and come into contact with the host plant. The environmental conditions must favor the infection and the plant must be susceptible. So our goal is to break the cycle of infection. The most common diseases of orchids are Bacteria, fungus and viruses. Here are a few ways to control them. |
a) Remove all dead and diseased plant materials. They are a major source of infection.
Sanitation is the best defense against diseases. b) Control weeds and pests in and around your growing area. Weeds and other plants in the collection often harbor insects that can transmit a disease. c) Maintain good air circulation. Do not overcrowd your orchids. d) Avoid damaging the orchids, as it provides an entry for disease. e) Maintain proper sanitation when handling, sterilize potting utensils. f) Quarantine new orchids and isolate diseased ones. |
3) Managing Insects: It is very important that you watch your orchids carefully and take care of problems as they occur. Most insect problems occur in the warm summer months and best time to spot problems is while you are watering. If you stay on top of things, spot spraying of pesticides may be all that is needed to rectify the problem. When using pesticides, always wear protective clothing and always follow label directions. See Insect Control Chart.
4) If protective clothing is not available, there are many ready to use 'soap' products on the market today that are safer for the applicator and environment. See Home Remedy Chart. |
