247: 172: 618: 452: 856:. In addition, its properties mean that it can be applied to soil so emerging weeds take it up and are controlled. Alternatively, spraying after weeds are already present in the crop will also lead to control. This combination of properties has meant that mesotrione achieved widespread use very quickly and reached annual sales of more than $ 400 million by 2011. The product is used at application rates of 75-150 g/ha. 660: 922:, becoming resistant to mesotrione are monitored by manufacturers, regulatory bodies such as the EPA and the Herbicides Resistance Action Committee (HRAC). In some cases, the risks of resistance developing can be reduced by using a mixture of two or more herbicides which each have activity on relevant weeds but with unrelated mechanisms of action. HRAC assigns active ingredients into classes so as to facilitate this. 770: 609: 697: 627: 27: 1308: 1171:

The estimated annual use of mesotrione in US agriculture is mapped by the US Geological Service and shows an increasing trend from its introduction in 2001 to 2018, the latest date for which figures are available and now reaching 4,500,000 pounds (2,000,000 kg). As would be expected for a
