To: THIERFELDER, Christian Lutz (CIMMYT-Zimbabwe) <[log in to unmask]> Dear Colleagues, Biological control in cropping system has become an increasingly hot topic, specifically in CA systems where we try to reduce the environmental footprint – this data was taken before the Fall Armyworm became a major pest in Africa. As you can see we are slowly transgressing to R. Thanks to Blessing and all teachers involved who helped us in getting that far… [image: image.png] Enjoy the read!
