Pesticide application can artificially select for resistant pests. In this diagram, the first generation happens to have an insect with a heightened resistance to a pesticide (red) After pesticide application, its descendants represent a larger proportion of the population, because sensitive pests (white) have been selectively killed.
Cross-resistant and multiply resistant weeds resist multiple MoAs, [6] and are particularly difficult to control. There is limited evidence of resistance undoing other resistances. For example, prosulfocarb and trifluralin : their inverse mechanisms of resistance contradict, and so by evolving to one the weed loses resistance to the other, at ...
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 ...
Three key points are taken into consideration regarding MRL values in the EU regulation: [4] 1) the amounts of residues found in food must be safe for consumers and must be as low as possible, 2) the European Commission fixes MRLs for all food and animal feed, and 3) the MRLs for all crops and all pesticides can be found in the MRL database on the Commission website.
The Insecticide Resistance Action Committee (IRAC) definition of insecticide resistance is ' a heritable change in the sensitivity of a pest population that is reflected in the repeated failure of a product to achieve the expected level of control when used according to the label recommendation for that pest species '.

Indian toxicity label system Toxicity symbol for European toxicity class I and class II. Toxicity class refers to a classification system for pesticides that has been created by a national or international government-related or -sponsored organization.
When infected deer congregate at an artificial feeding site, they could easily infect other deer that visit the same site. “It’ll facilitate more rapid transmission of disease,” says Fuda. 4.
Such mutative resistance is characterized by the presence of kdr alleles in the insect's genome. Knockdown resistance, first identified and characterized in the house fly (Musca domestica) in the 1950s, remains a threat to the continued usefulness of pyrethroids in the control of many pest species. Research since 1990 has provided a wealth of ...
