Cultural
Practices:
Although a weed of turfgrass, it can be found in nurseries and other ornamental
settings. Also found along roadsides. Yellow rocket prefers loamy nutrient
soils. Culturally, yellow rocket can be controlled by mowing to prevent
the formation of flowers and seed. The existing plant can be dug and removed.
Herbicide
Use:
Since yellow
rocket is a winter annual which germinates in the fall, postemergent herbicide
applications will be most effective at this time. Use a selective postemergent
application timed after germination when plants are young and actively
growing.
