The effect of pesticides on field-controlling root rot of Vicia faba was studied in two consecutive years by seed treatment of fungicides and their combination. The results of the first year field experiments showed that among the 11 treatments tested, triadimefon of 0.01 g a.i.kg-1 seeds was more effective than other fungicides applied singly or in combinations. The other test fungicides included thiophanate-methyl, thiram, oxadixyl and metalaxyl. Compared to the control, triadimefon treatment reduced the root rot index of 6-week-old seedlings by 51.5%, and plant accumulated percent mortality by 36%. Consequently, the treatment increased seed yield/plant by 21% and seed yield/ha by 97.6%. In the trials carried out in the following year, the plant percent mortality was reduced by 31.9% and seed yield increased by 19.6% under triadimefon seed treatment. It is demonstrated that seed treatment by triadimefon effectively controlled root rot, promoted plant growth, and increased seed yield of faba bean in the fields.
通过使用杀菌剂及其组合进行种子处理，连续两年研究了农药对蚕豆田间防治根腐病的效果。第一年田间试验结果表明，在所测试的11种处理中，每千克种子使用0.01克有效成分的三唑酮比单独或组合使用的其他杀菌剂更有效。其他测试杀菌剂包括甲基托布津、福美双、恶霜灵和甲霜灵。与对照相比，三唑酮处理使6周龄幼苗的根腐病指数降低了51.5%，植株累积死亡率降低了36%。因此，该处理使单株种子产量提高了21%，每公顷种子产量提高了97.6%。在次年进行的试验中，三唑酮种子处理使植株死亡率降低了31.9%，种子产量提高了19.6%。结果表明，三唑酮种子处理能有效控制田间蚕豆根腐病，促进植株生长，提高种子产量。
