The intensive use of agro-insecticides by farmers in the
Tamale Metropolis of Ghana has resulted in the detection of
high insecticide residues in vegetables, local health
hazards and environmental pollution. This study investigated
the knowledge and practices of cabbage growers regarding the
use of insecticides in the management of insect pests of
cabbage. A survey of 70 cabbage farmers was conducted in
seven different production sites in the Metropolis. Cabbage
farming system in the Metropolis typically consisted of
smallholder farmers growing one or two cabbage varieties.
The diamondback moth, Plutella xylostella remained the major
insect pest in cabbage. More than 90% of farmers applied
pesticides for pest control. There were 12 major types of
insecticides used in pest control and each farmer usually
used 3–4 types of insecticide over a season. Both high and
low toxicity pesticides, with EIQ values ranging between
10.0 and 52.5, were used. Pesticide spray frequency was
higher during wet seasons than in the dry seasons. The study
also revealed that hypermarkets play an important role in
marketing of fresh cabbage in the food chain. Regulations on
pesticide residue monitoring need to be applied in order to
help address the high insecticide residues on fresh products
and their impact on animal and human health in the
