説明
A new soil fungicide, which have a plant growth regulating activity, methasulfocarb [S-(4-methylsulfonyloxyphenyl) N-methylthiocarbamate, Kayabest®, NK-191], promoted the root elongation of rice seedlings in water culture. The maximum elongation was obtained at its concentration of 25, 50, 100ppm, when the roots grew 1.5 times longer than those of untreated control. The elongation of roots was also promoted in the nursery soil treated with methasulfocarb. Methasulfocarb 10% dust, applied in soil, was effective to prevent the development of murenae, the acute wilt symptom of rice seedlings, in nursery stage. The application of methasulfocarb 10% dust at the rate of 8g (800mg a. i.) per 5l soil prevented the spindly growth of rice seedlings by inhibiting the excess growth of primary leaf sheaths. The seedlings in treated plots showed a greater top dry weight/plant height ratio and a smaller top dry weight/root dry weight ratio than those in untreated plots. Methasulfocarb treated plots provided the substantial and good quality rice seedlings, which enhanced the elongation of newly developing roots and exhibited a high rooting ability at low temperatures and a high geotropic curvature response when transplanted. The seedlings quickly developed their own root system in paddy soil immediately after transplantation and continued healthy growth and development in the early stage of rice plant after transplantation under flooded condition.
