Biocontrol Potential of Endophytic Fungi against Orobanche Infestations in Fruit Crops: A Case Study in Delta State, Nigeria

Abstract

This study investigated the potential of endophytic fungi as biocontrol agents against Orobanche infestations in fruit crops such as chickpea, soybean, lentil, and pea plants from different sites in Ika agricultural habitats in Delta State, Nigeria, using appropriate standard methods. Fusarium sp. showed significant inhibition of Orobanche crenata (75%) by mycotoxin production and Penicillium sp. (65%) by biocombustion. Field trials showed a significant reduction in Orobanche-infested areas, with Fusarium sp. (40% to 10%) and Penicillium sp. (30% to 10%) treatments showing significant yield improvement (20% and 22%, respectively). The study concluded that selected fungi, especially Fusarium sp. and Penicillium sp., are effective control agents for Orobanche in legume crops. This information contributes to sustainable agriculture by providing environmentally friendly alternatives to pesticides, crop yields, and economic losses from plants, and it reduces the incidence of pests.
