摘要

1．本試驗根據本文第一報之室內試驗結果，在盆栽及田聞舉行防治上之應用試驗。
2．盆栽試驗時以五種鎘化合物與Asozin作防治效果之比較得知CdSO4與CdCl2二種化合物之防治效果良好，但藥害亦甚。
3．藥害問題曾加用生石灰(CaO)二倍量獲得消除。
4．田間試驗結果CdCl2及CdSO4對本病之防治效果比Asozin爲佳。

1. The experiment of control effect was based on the results of the indoor test in our first report (Report 1) and practiced in pots and field.
2. We compared the effects of five cadmium compounds with Asozin in pot culture, and found that CdSO4 and CdC12 were the most effective ones but had severe phytotoxity.
3. The problem of phytotoxity was solved by adding two parts of calcium oxide to one part of CdSO4 or CdCl2.
4. The results of the field experiment showed that the control effect of CdC12 and CdSO4 were better than that of Asozin.
