内容記述(抄録等)
Three kinds of tests with NANKOR were made to secure control of ticks which live upon cattle. The densities of NANKOR were 0.25%, 0.5% and 1.0%.
Test1. The effect of NANKOR remaind at least 14 days after prepared for a test.
Test2. The number of ticks on the cattle decreased after 24 hours as a result of the treatment with each density in the summer test, and in the autumn test, the number of ticks decreased after 24 hours and the decrease went on for 3 weeks.
In the latter case the effect of NANKOR increased in direct proportion to its density.
Test3. The spray with NANKOR was followed by so㎜e decrease of the number of ticks in the pasture.
