Review on the Integrated Management of Cercospora Leaf Spot of Groundnut (Arachis Hypogaea L.) Through Host Resistance And Fungicides

Abstract

Cercospora leaf spot of groundnut caused by cercospora arachidicola (early leaf spot) and cercosporidium persomatum (late leaf spot) are the most wide spread diseases of ground nut that result in severe yield losses. Most of the farmers do not apply disease control measures like chemical application and improved variety selection. Therefore it is necessary to develop suitable disease management practices for ground nut crop. Effective control of leaf spot diseases can be achieved by applying recommended fungicides. However repeated application of fungicide could lead to reduced efficacy of the fungicides great production costs and environmental pollution. Therefore the planting of moderately resistant variety will reduce the use of fungicides and associated expenses and increase economic gain. Thus farmers will benefits economically from plants resistant varieties and also using of integrated management are preferred approach of managing agricultural pests. It is the careful consideration of all available pest control techniques and subsequent integration of appropriate measure that discourage the development of pest population and keep pesticide and other intervention to level that are economically justified and reduce or minimize risks to human health and the environment.
