a. This question was well attempted by candidates. Majority of the candidates correctly stated the effects of specimen P(Aphid) and ways of controlling specimen P.
b. Most candidates were able to give two benefits derivable from including the crop from which specimen Q was obtained from in a mixed cropping system. They were also able to write bean beetle as the major storage pest of cowpea seeds.
