They are also used for brush in pastures, rangeland, and non-cropland and for general vegetation control. Soil persistence varies from weeks to months depending on compound and dose and soil pH. Soil mobility varies from low to high depending on the compound and soil characteristics. Use for aquatics has been discontinued. Detection in and public concern regarding surface and ground water may result in severe restrictions on use of the triazine herbicides. These herbicides inhibit the steps in plant cell division responsible for chromosome separation and cell wall formation.
Roots are relatively few in number and club shaped.
Except for oryzalin, these compounds have water solubility less than one part per million. They bind to soil colloids and are unlikely to leach. Losses occur through volatilization and photodegradation on soil surfaces. Incorporation into the soil by mechanical mixing or by overhead irrigation soon after application is routinely suggested. These root inhibitors do not translocate.
