GMO adoption in Ghana assessed
The adoption of genetically modified crop technology in Ghana would likely lead to reduced insecticide use on cabbages, but not on tomatoes or aubergines, a study has found. The part government- and private-funded International Food Policy Research Institute (IFPRI) carried out a survey to estimate the effect of GMO adoption on insecticide use on the three crops. The IFPRI says the adoption of GMOs would only impact on insecticide use on cabbages as insecticides only significantly reduce damage to that crop among the three. Overall, farmers would most likely continue to use wide-spectrum insecticides against secondary pests, it adds. The authors expect that GMO adoption would reduce the use of insecticides to control biotic constraints such as diamondback moths ( Plutella xylostella) on cabbages, shoot and fruit borers on aubergines and tomato yellow leaf curl virus on tomatoes.
