IN-VIVO CONTROL OF FUSARIUM MONILIFORME CAUSING ROOT ROT OF JATROPHA THROUGH CHEMICAL AND AQUEOUS PLANT EXTRACTS

Abstract

Jatropha (Jatropha curcas) is a plant of the Euphorbiaceae family that grows fast and able to be cultivated in tropical and subtropical regions. It is also known as Jamalghota and Jangli in different regions of the world and reported to be grown along with other crops such as wheat, sunflower, cluster bean, and pearl millet.Jatropha seeds were collected from the field of a project run by the Department of Agronomy, Sindh Agriculture University, Tando Jam. In the isolation process, seeds of jatropha were surface sterilized in a 5% bleach solution for 1-2 minutes to remove contamination.The experiment was carried in nursery bags to seethe effect of different doses of plant extracts on root rot of jatropha. The aqueous extract of different plant species was prepared by grinding freshly collected leaves of Neem, Ginger, Basil, Acasia, Garlic, Toothbrush plant, Eucalyptus, Giant milkweed, Mint, and Aloe vera separately. These extracts were then stained with a muslin cloth and a piqued solution was stored. Later it was used at the dose of 10ml, 20ml, and 30ml per bag containing disease-free (sterilized in soil sterilizer) soil. For comparison, two treatments (untreated, inoculated, and untreated, un-inoculated) bags were placed.The results of the experiment showed a significant growth of shoot length and weight in inoculated plants treated with the highest dose of Aliette, followed by Carbendazim, and Metalyxl+Mancozeb. Whereas minimum shoot length and weight was observed in control. Similarly, maximum root length and weight were recorded in plants treated with Aliette, followed by Carbendazim and Metalyxl+Mancozeb as compared to control.
