Induced Resistance in Solanum lycopersicum by Algal Elicitor Extracted from Sargassum fusiforme
Tomato (Solanum lycopersicum) production relies heavily on the use of chemical pesticides, which is undesired by health- and environment-concerned consumers. Environment-friendly methods of controlling tomato diseases include agroecological practices, organic fungicides, and biological control. Plan...
