When applied, preemergence weeds absorb the herbicide during emergence from the soil. Producers should use their own rainfall records to estimate their specific risk of carryover injury from the herbicide they used the previous year to following crops, or if dry conditions have been experienced over multiple years in a row, potentially residues from previous few seasons as well. The map below indicates the amount of rain between early June and early September. Three benefits of selecting a pre-emergence herbicide with residual . Soil activity varies from almost none to long residual depending on herbicide and dose. An herbicide described as having high residual activity will remain potent for a long term in the soil. Auxin growth regulator herbicides are used for control of annual, simple perennial, and creeping perennial broadleaves in grass crops (corn, small grains, sorghum, turf, pastures, sodded roadsides and rangeland) and in … Susceptible plants emerging later in the season following use of a long-residual herbicide (or multiple applications of a non-residual herbicide) are still exposed to the herbicide, thereby increasing selection pressure. Time POST herbicide applications when weeds are no more than 2 to 3 inches tall. The residual activity of a herbicide is commonly referred to as its half life, which is defined as the time required to dissipate one half of the applied herbicide. This is A flexible application window enables Prefix to be applied as a preemergent herbicide or, if spring weather keeps you out of the field, an early post-emergent herbicide with residual control of up to five weeks.
