Parasite-resistant maize developed by Kenyan scientist

Two new varieties of hybrid maize that are resistant to the deadly parasitic Striga weed have been developed by a Kenyan scientist. The weed affects cereal crops in many parts of Africa and is a major cause of crop failure in East Africa, where climate change has been driving its spread in recent years. Mathews Dida, a maize breeder in the school of agriculture and food security at Maseno University, developed two maize varieties that produce a natural chemical that suppresses the growth of Striga weed, also known as witch-weed.
