Increased yields with Bt maize are signicantly higher in developing countries although the average yield may be lower;
Bt maize is more suitable for small farmers because it does not require the equipment, knowledge and information required for insecticide applications. It also reduces the farmer’s exposure to chemical pesticides.
Given that maize is a staple food in Africa and that mycotoxin levels are signi cantly higher in developing countries, the use of Bt maize to lower mycotoxin levels is important.
Increased yield directly affects food security and food/feed safety. Increased income from higher yields contributes to the alleviation of poverty in those cases where the need is the greatest.
BT MAIZE DEMONSTRATION TRIALS
Figure 2: Demonstration trials conducted in different areas of South Africa from 2003 to 2013.
• Over the past ten years, Bt white maize produced a higher yield (an average of 9%) than its unsprayed conventional maize counterpart.
The adoption of Bt maize will play a key role in achieving increased food security in Africa. Signi cant bene ts include yield increases,reduced pesticide usage and lower mycotoxin levels.
