Popis: | In laboratory and field experiments at Mysore, cut pieces of potato cv. Kufri Jyoti tubers were treated with 7 antimicrobial chemicals at a variety of concn to control decay caused by Erwinia carotovora and Fusarium oxysporum. Mercuric chloride was the most effective in controlling decay, followed by streptocycline, Dithane M-45 [mancozeb], ferrous sulphate, Emisan [2-methoxyethylmercury chloride], Bavistin [carbendazim], Oxine [oxine-copper?] and TEM, a trace element mixture. Mercuric chloride was most effective at a concn of 100 mg/litre but the other fungicides gave increasing levels of control up to the highest concn tested (500 mg/litre). Tuber yields ranged from 9.7 kg/plot with mancozeb to 15.6 kg with TEM. In experiments on dormancy breaking in seed tubers stored at 4 |
