"Selectivity is the ability of herbicides to be toxic to selected plant species without causing toxic effects to the other ones. There are high differences among herbicides in their selectivity to crop species. Herbicide selectivity is based on different mechanisms that can be combined. The most common mode of selectivity is based on physiological and biochemical differences between plant species. Tolerant species are able to metabolise herbicide in a short time, they can have modified structure of target enzyme or they show overproduction of this target enzyme compared to sensitive species. To support this type of selectivity, herbicide safeners are often used. Morphological or anatomical differences between crop species and sensitive weeds can also significantly influence the selectivity of herbicides. In case of selected pre-emergent herbicides, position selectivity is used, based on different root uptake zone between weeds and crop."@en . . . "41210" . "Soukup, Josef" . "195583" . .
