防治水稻褐飛蝨藥劑田間比較試驗

Abstract

A total of 35 insecticides have been registered with the government for the brown planthopper control since last 10 years. Recently, Some of these chemicals have been found by no means satisfactory to control the brown planthopper by the extension workers and farmers. In order to provide a basis for the farmers to select more effective insecticides from among these compounds, a series of experiments were then conducted in Chiayi and Taichung districts simultaneously to reevaluate those chemicals under field conditions in 1975 and 1977.
