✦ Synopsis
Eighteen fungicides were first evaluated for their effects on growth of Alternaria brassicae and for ascertaining their fungicidal and fungistatic natures in artificial cultures. The chemicals emerging fungicidal in action, were later evaluated for their efficacy as seed treatment and foliar application in the management of damping-off of seedlings and blight of rapeseed separately. Of 18 fungicides tested, six fungicides, viz., Dithane M-45, Dithane Z-78, Ziram, Difolatan-80, Blitox-50 and Benlate completely inhibited the growth of the pathogen and were fungicidal in action. Thiram and Brestan-60, which also caused total growth inhibition, were, however, fungistatic. Benlate (0.1 ~) followed by Dithane M-45 was best seed-dressing fungicide for controlling damping-off of seedlings. Dithane M-45 (0.2~) followed by Dithane Z-78 as foliar spray was most effective for controlling the blight and increasing the yield in field trials.
