Recent Trend of Bio-Fungicide and Pesticide in Agriculture
Abstract: Biopesticides, which are commonly employed to combat harmful phytopathogens, are derived products made from living microbes, including plants, animals, fungi, bacteria, viruses, and minerals, as well as their bioproducts. In contrast to synthetic fungicides, the use of biopesticides in agricultural fields is a more cost-effective, environmentally safe, and target-specific method due to their biodegradability and environmental safety. Trichoderma spp.-based biofungicides are currently regarded as the most promising and dominant commercial …
