ABSTRACT
Concerns have been expressed by pesticide management specialists about the choice and use of
insecticides in cabbage production and fear o f toxic residues on harvested cabbage head. This
investigation involves a survey to determine cabbage fanners’ insecticide use patterns and analysis
for insecticide residues on samples o f cabbage.
The survey revealed that cabbage growers in the Accra-Tema Metropolitan area o f Ghana
invariably relied on insecticide retailers/agents for advice on the choice and use o f insecticides for
insect pest control purposes. The insecticides o f choice were, Bacillus thuringiensis subsp.
kurstaki Berliner, Lambdacyhalothrin, Chlorpyrifos, Dimethoate, Deltametrin, Triazophos,
Cypermethrin, Profenofos and Pirimiphos-methyl. These insecticides were used either in
alternation or as mixtures. Additionally, the insecticides were sprayed frequently and at short
intervals on cabbage without the consideration o f threshold levels.
Residues of Karate 2.5 EC (Lambdacyhalothrin) and Deltaphos 262 EC (250g/l Triazophos +
12g/l Deltamethrin) were determined on samples o f cabbage, by estimation o f biotoxicity to the
brine shrimp nauplii. Residues o f Lambdacyhalothrin were lower than the FAO/WHO
recommended maximum residue level (MRL). The residues o f Deltaphos 262 EC detected,
however, suggested that the residue levels o f Triazophos were likely to be higher than FAO/WHO
recommended MRL
