But, what do we truly know about them? Some believe all the pesticides do is kill the bugs and weeds that try to disturb the development or harm the crop. As it may be true to a point, I believe there are many benefits to using pesticides on crops in agriculture. One major benefit to pesticides is that they kill pests, such as weeds, insects, and plant pathogens. “In the USA, approximately 500 million kg of more than 600 different pesticide types are applied annually at a cost of $10 billion” (Pimentel, 2005). Even with all the pesticides being used in the US, pests still destroy 37% of all potential crops, insects 13%, plant pathogens 12% and weeds 12%. Thus, for every dollar put into pesticides, about $4 in protected crops are returned (Pimentel,
