Glyphosate Exposure

Glyphosate Exposure

Researchers grew oyster mushrooms (Pleurotus ostreatus) on substrates exposed to glyphosate herbicide and found measurable changes in growth and chemical composition. Higher glyphosate levels were associated with reduced yield and shifts in antioxidant and nutrient-related compounds.
