Tomato, cabbage, and garden egg are important crops for small-scale farmers and migrants in the rural and peri-urban areas of Ghana. Genetic modification has the potential to alleviate poverty through combating yield losses from pests and diseases in these crops, while reducing health risks from application of hazardous chemicals.

Cotton, as a commercial crop has gone through subsistence, ecological, exploitation, crisis and disaster phases of pest management, with insecticides on focus at the later three stages. Restructuring of pest-management strategies during the last few decades under the banner of Integrated Pest Management (IPM) or Insecticide Resistance Management (IRM)continued to give considerable and selective preference respectively, to the insecticides. Such an approach could only achieve the short-term benefits of reducing the pesticide usage and improving the profit accrued by the farmers.
A pot experiment was conducted to study the toxic effect of nematicides: carbofuran, carbosulfan alone and their combination on soil microbial population and soil respiration with cotton as a test crop.
