Damage caused by Meloidogyne incognita to five cultivars of chrysanthemum and its chemical control
International Journal of Nematology 15 (2), 199-202
Abstract: An experiment was conducted to assess the damage caused by the root-knot nematode Meloidogyne incognita (2000 J₂/plant) to five common cultivars of chrysanthemum, Dendranthema grandiflora, cvs. Kiran, Jaya, Orange Yellow, Sarad Bahar and Apsara. The effect of soil application of fenamiphos was evaluated on the root-knot disease, soil population of the nematode, and plant growth and flowering of chrysanthemum cultivars. All cultivars were found susceptible to nematode infection. However, greatest number of galls (42-49 galls) developed on the cultivars Orange Yellow, Kiran and Sarad Bahar and the least (22 galls/root system) on cv. Apsara. Soil population of the nematode increased in all cultivars except Apsara: As a result, plant growth was suppressed significantly (P < 0.05) in the cultivars Orange Yellow, Kiran and Jaya. Soil application of fenamiphos satisfactorily controlled the nematode and significantly improved the flowering of the cultivars that were more susceptible to the nematode.
