The efficacy of both botanical pesticides and entomopathogenic nematodes (EPN) is largely dose-dependent and driven by environmental conditions. Combination of the EPNs and botanicals may enhance their efficacy; thus, we investigated the compatibility of the medicinal plants Alepidea amatymbica and Elephantorrhiza elephantina with five locally isolated EPN strains, three Steinernema (S. khoisanae, S. biddulphi and S. innovationi) and two Heterorhabditis (H. bacteriophora and Heterorhabditis sp. SGI 244).

Black gram anthracnose caused by Colletotrichum lindemuthianum is the most devasting disease. Due to its severe infection during humid climatic conditions spraying of chemical fungicides is essential to control the disease. Frequent application of synthetic chemicals, leads to the detoriation of environment and development of resistance. The present study was carried out to manage black gram anthracnose pathogen using plant extracts.
