Specific chemistries are used to protect crops from insects, weeds, fungi and other microbes. Legacy issues with some older pesticides led to restrictions or bans on their use. Unfortunately, suspicion remains around contemporary solutions, even though today's chemistries are highly specific, with low toxicity to non-target organisms, including humans. Use of crop protection compounds it critical to agriculture, yet activist groups continue to use fear, uncertainty and doubt to override what we really know about the abundance of these compounds in food and the relative toxicity at levels detected.
