EFFECT OF EXTRACTS OF AZADIRACHTA INDICA, KHAYA SENEGALENSIS AND BOSWELLIA DALZIELII ON THE DEVELOPMENT OF THE ANGULAR LEAF SPOT, GROWTH AND DEVELOPMENT PARAMETERS OF RICE (ORYZA SATIVA L).
Journal Title: International Journal of Advanced Research (IJAR) - Year 2019, Vol 7, Issue 9
Abstract
Rice is one of the most widely grown and consumed cereals in Chad. However, its production decreases over the years due to bio-aggressors. This situation pushes farmers to use chemical synthetic plant protection products to remedy insect and disease attacks. These chemicals expose them to risks of poisoning and environmental pollution. To reduce the use of these chemical pesticides, extracts of Azadirachtaindica, KhayasenegalensisandBoswelliadalzielii were used to treat rice seeds. These seeds were soaked separately in the different extracts used at a concentration of 50 mg/ml for one hour before sowing. The incidence and severity of the angular spot, growth and development parameters were assessed. The three types of plant extracts showed a high reduction in the incidence and severity of the disease, and improved certain growth and development parameters. These plant extracts could be used as bio-fungicides in rice cultivation.
