Final answer:
RNAi pesticides have been developed to be the most accurate in targeting a specific pest.
Step-by-step explanation:
The family of chemicals that has been developed to be most accurate in targeting a specific pest is RNAi pesticides.
RNAi pesticides work by disrupting the gene expression in the targeted pest, causing it to die. These pesticides are designed to specifically target and affect the pests, minimizing harm to other organisms and the environment.
For example, some RNAi pesticides are absorbed by the crop and only affect the pest that feeds on it, while others are topical applications that directly target the pest. This targeted approach makes RNAi pesticides highly accurate and effective in pest control.
