Recently many data on the effect of mist spraying of insecticides for fruit trees and vegetable crops have been published in Japan. In order to make a comparative study on the effectiveness of mist and hydraulic sprayings, the authors prepared a genral view of the above-mentioned data (Fig, 1), taking the combination of concentration and dose of insecticides into consideration. From the graph the authors were able to present a standard system of mist spraying concerning the two factors mentioned above. The figures of the both factors, which the authors are going to recommend, are shown by the relative value against hydraulic spraying, and the values are tabulated as follows. [table] The authors investgated the effective range of mist spraying in pear orchards and various vegetable gardens. It was recognized from the experiments that the effective spraying to the lower hinder parts of vegetables was not easy in general. It was also acknowledged that a close relationship between the arrival of insecticides to the underside of leaves and turning of leaves was existed in trees. The authors confirmed the fact by model experiments, too (Fig.5).
