In Thailand, orchids are flowers of economic importance. At present, orchid growers are overusing insecticides. This results in higher cost of production and lower quality of cut flowers. In addition, insecticides are hazardous to human beings, animals and environment. The main objective of this research was to study certain socioeconomic background of the orchid growers, factors involving use of insecticides, how to use them in controlling insect pests of orchids, problems and suggestion with regard to their use. Data were collected through interviewing 110 orchid growers in Khet Phasi Charoen and Khet Nong Kham, Krung Thep Maha Nakhon from September 30, 1991 to October 15, 1991. On the average, most of the orchid growers were male, 46 years of age and had the educational background of prathom 1-prathom 4. They had grown orchids commercially for 11 years. The average number of planting area per person was 7 rai. Most of the growers were not in debt. They had 17 years of experience in using isecticides. These chemicals were applied 4 times a month. The information regarding how to use insecticides was mostly obtained from publications and neighbors. Use of insecticides by the growers had positive relation with knowledge, educational background and the number of information sources, but had negative relation with the number of years the growers had use insecticides.
