(Phys.org) -- Because they can modify plants to either produce better fruit or in many other cases ward off disease and pests, researchers genetically alter crop plants to increase yields without adding additional costs to ...
Toxins from Bacillus thuringiensis bacteria (Bt toxins) are used in organic and conventional farming to manage pest insects. Sprayed as pesticides or produced in genetically modified plants, Bt toxins, used in pest control ...
