|
Root inhibitors
|
-Dinitroanilines-"yellow" herbicides
-inhibit steps in plant cell division and result in fewer roots and club shaped roots -except for oryzalin have water solubility <1ppm and bind to soil so unlikely to leach -losses from volatilization and photodegradation on soil surfaces -trifluralin (Treflan), ethalfluralin (Sonalan), pendimethalin (Prowl), oryzalin (Surflan) |
|
 Shoot inhibitors
|
-soil applied for control of seedling grasses, some broadleaves and suppression of some perennials from tubers and rhizomes
-injury appears as malformed, dark green shoots and leaves -grass crops with some resistance can be protected with safeners and protectants -EPTC (Eptam), acetochlor (harness) |
|
Shoot and root inhibitors
|
-preplant incorporated, preemergence and sometimes early postemergence for control of annual grasses, and some broadleaves in small seeded legumes, established woody species, established turf, established herbaceous perennials
-pronamide (Kerb), dichlobenil (Casoron) |
