This powerful approach combines scientific inquiry with place-based knowledge and experimentation, emphasizing approaches that are knowledge-intensive, low cost, ecologically sound and practical. Agroecology is the science behind sustainable farming. Rachel Carson clearly predicted the treadmill phenomenon in her 1962 book Silent Spring. Between 500 and 1,000 insect and weed species have developed pesticide resistance since 1945. Since the 1980s, loss has increased to 13 percent, even though more pesticides are being used. farmers lost seven percent of their crops to pests. Overall, pesticide resistance is increasing. Resistant strains of "Pigweed" for instance, reportedly now grow with such vigor in southern cotton fields that the weeds can "stop a combine in its tracks." Farmers are forced to return to use of 2,4-D - an antiquated, drift-prone chemical clearly linked to cancer and reproductive harms. Widespread planting of RoundUp Ready crops and the associated application of RoundUp prompted weeds to develop resistance to the product. The recent introduction of crops genetically engineered for use with the herbicide 2,4-D provides a clear example of the pesticide treadmill.

For more details on specific pesticides, visit our online database at What is the “pesticide treadmill?”Īlso referred to as the "pesticide trap," farmers get caught on the treadmill as they are forced to use more and more - and increasingly toxic - chemicals to control insects and weeds that develop resistance to pesticides.Īs "superbugs" and "superweeds" develop in response to widespread and continous use of chemicals, a farmer will spend more on pesticides each year just to keep crop losses at a standard rate. Newer classes include pyrethroids and neonicotinoids, synthesized to mimic nature's pest protection. Major chemical classes include: carbamates, organochlorines, organophosphates (mostly developed 70 or more years ago for chemical warfare) and triazines. For example, fumigants are pesticides applied as gases to "sterilize" soil, and systemics work their way through a plant's tissue after being taken up at the root. Pesticides are also sometimes broken down into chemical classes and modes of action. Fungicides are also used in large amounts some are more benign, some are not. This means ongoing, low-level exposures can increase the risk of diseases or disorders such as cancer, Parkinson’s disease or infertility and other reproductive harms. Herbicides are more widely used (RoundUp and atrazine are the two most used pesticides in the world) and present chronic risks. Many are designed to attack an insect's brain and nervous system, which can mean they have neurotoxic effects in humans as well. Insecticides are generally the most acutely (immediately) toxic. Pesticides come in spray cans and crop dusters, in household cleaners, hand soaps and swimming pools. Insecticides (bug killers), herbicides (weed killers), and fungicides (fungus killers) are all pesticides so are rodenticides and antimicrobials. Yet as public concern continues to grow, alternative approaches to managing pests are increasingly available and gaining ground in homes, schools and agricultural fields across the country.īelow is a brief overview of the problem explore our campaigns and key issue pages to find out more about how PAN and our partners are building a healthy, thriving system of food and farming - and how you can help. Our national rules governing pesticide use are surprisingly weak. The science is increasingly clear that even low levels of exposure can harm human health, and children are particularly vulnerable. Pesticides are used all around us, in homes and gardens, schools, parks and agricultural fields.Īll too often, these chemicals are allowed onto the market before their impacts are fully understood - and harms to our health and the environment are discovered years later.
