The side effects of the various preventive and control measures of pests and diseases of crops include the following except

The preventive and control measures of pests and diseases of crops have various side effects, including environmental pollution, poisoning of wildlife, and disruption of the ecosystem. These measures are often implemented to improve the quality of farm produce and protect crop yield, but they may also expose farmers to health hazards. However, the option that does not fit with the rest is "improvement in the quality of farm produce." This is because this option does not describe a side effect but rather a desired outcome of implementing preventive and control measures. The other options all describe unintended consequences or negative impacts on the environment, wildlife, and human health that can result from the use of pesticides and other control measures.
