| dc.description.abstract | The incidence and severity of Botrytis blight of gladiolus (Botrytis gladiolorum Timm.) and yield of the crop were the minimum in the early- and late-planted crop, as compared to the recommended planting date, i.e. 15th October. Closer spacing resulted in higher incidence and severity of the disease but the corm yield was recorded to be higher in the closer spacing as compared to the wider spacing. Plant spacing of 20x 20 cm was found to be suitable. Incidence and severity of the disease were also found to be high in the un-weeded control. Pre-emergence application of weedicide Stomp at 650 ml/ac, alone, and in combination with one manual weeding at six-leaf stage of the crop, recorded low incidence and severity of the disease and also registered high corm and cormel yields. Two manual weedings, at three- and six-leaf stages of the crop, respectively, also gave good results. Among the non-systemic fungicides, Dithane M-45 showed the best result under in vitro conditions as it completely inhibited spore germination of the pathogen at 100μg/ml, while Kavach and Antracol completely inhibited spore germination at higher concentrations of 500μg/ml. Among the systemic-fungicides, Stroby was the most effective fungicide, followed by Flint and Bavistin. Germ tube length of the fungus was found to be the minimum in Kavach and Dithane M-45. The fungicides Stroby and Flint were found to be the most effective fungicides against Botrytis blight of gladiolus under field conditions. The fungicides Kavach and Dithane-M-45 also showed very promising efficacy. | en_US |
