What would not generally produce pesticide residues on a treated crop?

The choice of storage of undiluted pesticides in a locked storage shed would not generally produce pesticide residues on a treated crop because this practice is focused on preventing access to the chemicals rather than applying them to the crops. Proper storage ensures that the pesticides are kept in a secure and controlled environment, minimizing the risk of accidental spills or environmental contamination that could lead to residues on crops.

In contrast, application according to label directions, improper mixing, and over-application directly involve the use of pesticides on the crops. When pesticides are applied, regardless of adherence to label instructions or mistakes during mixing, they can lead to residues on the plants. Over-application especially increases the likelihood of residues due to the excessive amount of pesticide applied, which may exceed what crops can adequately process, resulting in higher residues.
