Can organic plant protection products damage crops?

Protecting crops against pests and diseases is essential to ensure a secure food supply. Around 95 percent of food comes from conventional agriculture, which uses chemical pesticides to keep crops healthy. Increasingly, organic pesticides are sought as an alternative. Some organic pesticides contain live spores of the fungus Trichoderma to suppress other pathogens. Researchers at Göttingen University found one Trichoderma species can cause severe rot in cobs of maize (corn). Results were published in Frontiers in Agronomy.
