Appraisal of Fungi Leaf Spots of Groundnut (Arachis hypogea) and Control of Cylindrocladium Blight Disease Using Biocontrol, Botanical, and Chemical Measures

Groundnut is infected by 55 pathogens which adversely contribute to the low yield of groundnuts. Three sub-trials were conceived proffer solutions groundnut Cylindrocladium parasiticum disease. These (using biocontrol, synthetic and botanical measures) set up in vitro using completely randomized design with each treatment replicated thrice. Firstly, all biocontrol (Trichoderma) isolates showed a steady linear increase inhibition growth pathogen. There was no significant difference (P≤0.05) between Trichoderma harzianum at 96 h after inoculation (HAI). Secondly, pesticide Mancozeb® 100% significantly inhibited pathogen more than other chemical treatments, followed Mancozeb 50%, Tandem® Tandem 50% (which par (at 144 HAI)). Thirdly, Parkia sp. superior botanicals (192 HAI results). Likewise, Casuarina but performed better treatments except for 100%. Inhibition it (except 100%, 50%). Finally, trials that treatments.
