The effect of fungicide captan on growth and nitrogenase activity of Azospirillum brasilense Cd was studied in pure cultures and in association with foxtail millet (Setaria italica) cultivar Carapé under laboratory conditions. The 8 h growth in rotary shaker of A. brasilense was inhibited with 1 mg/l pure captan; however, after 4 days the differences diminished compared with the control without captan. Nitrogenase activity was affected with 10 mg/l but the differences were negligible after 48 h of growth. Root dry weight of inoculated plants was diminished by the treatment of foxtail millet cv. Carapé with captan. Inoculation with A. brasilense Cd increased shoot dry weight, but differences were significant only with respect to the control but not in relation to captan treatments.
在实验室条件下，研究了杀菌剂克菌丹对巴西固氮螺菌Cd生长和固氮酶活性的影响，该研究分别在纯培养物中以及与谷子（Setaria italica）品种Carapé联合培养的情况下进行。1 mg/l的纯克菌丹可抑制巴西固氮螺菌在旋转摇床上8小时的生长；然而，4天后，与未添加克菌丹的对照相比，差异减小。10 mg/l的克菌丹会影响固氮酶活性，但在生长48小时后差异可忽略不计。用克菌丹处理谷子品种Carapé后，接种植物的根干重降低。接种巴西固氮螺菌Cd可增加地上部干重，但差异仅相对于对照显著，相对于克菌丹处理则不显著。
