1.綿線法實驗結果，選出Brestan-60，Dithane M-22，Dithane M-53種藥劑有效。
In order to select the effective chemicals for the control of truffle disease of mushroom and to find out the proper use of them for the control of the disease, the experiments were carried out from 1964 to 1966 in the laboratory of Department of Plant Pathology, Taiwan Agricultural Research Institute, Taipei, Taiwan. It was found that these chemicals can control not only truffle disease but also the other diseases.
The results are summarized as follows:
1. The result of the screening test with cotton string method showed that Brestan-60, Dithane M-22 and Dithane M-45 effectively inhibit the growth of the causal fungus of truffle disease, at the concentration of 500 ppm.
2. However, it was also found that Brestan-6o, Dithane M-22 and Dithane M-45 were absorpted by soil (Zentmyer’s laboratory method). The only chemical found to be effective for control the growth of truffle fungus was Dithane A-40.
