1.Experimental tests of wettable powder of NANKOR 40% were made to examine its effect on ticks (Larva of Haemaphysalis bispinosa NEUMANN) which live upon cattle in the field, and at the same time to see if it has no toxicity on cattle.
2.Experiments were carried out at Sambe and Torikami, Shimane Prefecture in autumn 1969.
3.Three kinds of concentration of NANKOR, 0.8, 1.6 and 3.2%, were used in the tests.
4.NANKOR remained effective on the cattle at least 5-7days after the treatment.
5.There was no difference in effect among the three kinds of concentration.
6.The number of ticks on the cattle which had been treated with NANKOR, decreased, compared with that of the control.
7.No toxicity on cattle was recognized within the limits of this investigation.
