Question 1 Report

Maize is best stored against insect attack
Answer Details
Maize is best stored against insect attack in fumigated silos. Insects can easily infest stored maize, leading to losses and reduced quality of the maize. Fumigation involves using chemicals to kill insects that may be present in the maize. Fumigated silos are designed to be airtight and prevent re-infestation of the maize by insects after fumigation. Raised platforms, a sunny area, and humid metal tanks are not ideal storage options for maize. Maize stored on raised platforms is still susceptible to insect infestation, and exposure to moisture and humidity can cause the maize to spoil. Storing maize in a sunny area can also lead to moisture build-up, and this can cause the maize to mold. Humid metal tanks can also cause the maize to spoil due to moisture build-up, and they may not be airtight enough to prevent insect infestation. Leaving the maize still on the cob is not a suitable storage option either. The cob can provide a good breeding ground for insects, which can then infest the maize kernels.
