Pesticide resistance is increasing. Farmers in the US lost 7% of their crops to pests in the 1940s; over the 1980s and 1990s, the loss was 13%, even though more pesticides were being used. [1] Over 500 species of pests have evolved a resistance to a pesticide. [4] Other sources estimate the number to be around 1,000 species since 1945. [5]
A refuge area is a countermeasure against pesticide resistance in agriculture. [1] [2] [3] [4] [5] In this technique two adjacent pieces of land are demarcated, and ...
The Herbicide Resistance Action Committee (HRAC) classifies herbicides by their mode of action (MoA) to provide a uniform way for farmers and growers to identify the agents they use and better manage pesticide resistance around the world. [1] [2] It is run by CropLife International [3] in conjunction with the Weed Science Society of America ...
Pesticide resistance is increasing. Farmers in the US lost 7% of their crops to pests in the 1940s; over the 1980s and 1990s, the loss was 13%, even though more pesticides were being used. [102] Over 500 species of pests have evolved a resistance to a pesticide. [105] Other sources estimate the number to be around 1,000 species since 1945. [106]
The Insecticide Resistance Action Committee (IRAC) was formed in 1984 and works as a specialist technical group of the industry association CropLife to be able to provide a coordinated industry response to prevent or delay the development of insecticide resistance in insect, mite and nematode pests. IRAC strives to facilitate communication and ...
Acceptable pest levels—The emphasis is on control, not eradication. IPM holds that wiping out an entire pest population is often impossible, and the attempt can be expensive and unsafe. IPM programmes first work to establish acceptable pest levels, called action thresholds, and apply controls if those thresholds are crossed.
Based on government tests of pesticide levels, here is the Environmental Working Group’s 2024 list of the produce with the highest and lowest levels of pesticides.
[63] In 2017, the USEPA issued a revised Pesticide Registration Notice (PRN 2017-1), which provides guidance to pesticide registrants on required pesticide resistance management labeling. This requirement applies to all conventional pesticides and is meant to provide end-users with guidance on managing pesticide resistance. [ 80 ]
