| Abstract/Description: | An experiment was conducted at farmer's field on banana cv. Nendran (AAB) infested with root-lesion nematode. Maximum reduction in root-lesion index and nematode population was noticed, where Tagetes erecta was grown as an intercrop and on par with chemical treatment, whereas, maximum population was recorded in untreated control plants. The yield of banana increased significantly to 12.5 and 12 kg/plant in plants treated with chemical pesticides and intercropped with Tagetes respectively compared to a minimum bunch weight of 7 kg per plant in untreated control plants. Though the plants treated with chemical pesticides were found to be on par with marigold grown as an intercrop, but the use of marigold as an intercrop in banana field warrants more economical and ecofreindly compared to chemical nematicides. |
| Description: | Banana (Musa spp.), the most important fruit crop grown in India ranked second, next to mango, in area and production. Plant parasitic nematodes are widespread and are the most important pests of banana. Crop losses caused by nematodes in bananas are very high, with an average annual yield losses estimated at about 20 per cent world wide (Sasser & Freckman, 1987). The rootlesion nematode, Pratylenchus coffeae is one of the most important nematode pests of banana next only to the burrowing nematode, Radopholus similis. In India, losses caused due to root-lesion nematodes on banana cv. Nendran was estimated at about 44.4% (Sundararaju & Cannayane, 2003). In recent years due to prohibitive cost of pesticides and their toxicity to human beings and soil flora, considerable attention has been paid towards the control of nematode diseases by the use of botanicals. Intercropping of various nematicidal plants viz. sunhemp, sesamum, mustard, marigold etc. have been reported to be effective against nematodes infecting several crops (Boride et al. 1970). As there was no such report on control of root-lesion nematode infected banana plants, the present investigation was carried out to find out the appropriate combination of growing marigold as an intercrop in banana field and its effect on plant growth, yield and nematode populations. |
