SUMMARY

In laboratory tests, Rhizoctonia solani grew best on agar at 30 oC and pH 5-5. Mycelial growth was strongly inhibited by benomyl, chloroneb and quintozene, less so by thiophanate-methyl. The optimum temperature for inhibition was 25 oC for quintozene; the other three fungicides gave greatest inhibition at the lowest temperature tested (20 oC). Benomyl and thiophanate-methyl were most inhibitory at pH 7–8, chloroneb and quintozene at pH 5–6.

In pot trials using mung bean, long melon, egg-plant, common pea and sugar beet, R. solani caused maximum disease at 20 oC and in wet and alkaline soils. As seed treatments, benomyl and thiophanate-methyl gave optimum control at 20 oC and pH 7-6; chloroneb and quintozene were most effective at 30 oC and pH 5-4. All four fungicides gave maximum control on plants growing in wet sandy loam.

Comparisons of host effects showed that, on all the four hosts tested, thiophanate-methyl wettable powder at 0.25% (0.175% a.i.) gave 90% control, chloroneb w.p. at 0.3% (0.195% a-i-) gave 80% control on mung bean and sugar beet, benomyl w.p. at 0.3% (0.15% a.i.) was satisfactory on mung bean, egg-plant and sugar beet but not on long melon, quintozene w.p. at 0.3 % (0.225 % a-i-) gave effective control on sugar beet only.

Mycelial phát triển được mạnh mẽ ức chế bởi benomyl, chloroneb và quintozene, ít như vậy bởi thiophanate-methyl. Nhiệt độ tối ưu cho sự ức chế là 25 oC cho quintozene; 3 thuốc diệt nấm đã ức chế lớn nhất ở nhiệt độ thấp nhất được thử nghiệm (20 oC). Benomyl và thiophanate-methyl là ức chế nhất ở pH 7-8, chloroneb và quintozene ở pH 5-6.Trong nồi thử nghiệm bằng cách sử dụng bánh đậu xanh, dưa dài, egg-plant, phổ biến đậu và củ cải đường, R. solani gây ra tối đa bệnh ở 20 oC và trong đất ẩm ướt và kiềm. Như hạt điều trị, benomyl thiophanate-methyl, đã cho các điều khiển tối ưu ở 20 oC và pH 7-6; chloroneb và quintozene đã hiệu quả nhất tại 30 oC và pH 5-4. Tất cả bốn thuốc diệt nấm đã kiểm soát tối đa trên cây trồng trong loam cát ẩm ướt.Comparisons of host effects showed that, on all the four hosts tested, thiophanate-methyl wettable powder at 0.25% (0.175% a.i.) gave 90% control, chloroneb w.p. at 0.3% (0.195% a-i-) gave 80% control on mung bean and sugar beet, benomyl w.p. at 0.3% (0.15% a.i.) was satisfactory on mung bean, egg-plant and sugar beet but not on long melon, quintozene w.p. at 0.3 % (0.225 % a-i-) gave effective control on sugar beet only.The senior author is grateful to the Council of Scientific and Industrial Research, New Delhi, India, for the award of a Research Fellowship for undertaking these studies.
