Post-emergence Herbicides — Post-emergence herbicides kill or injure existing weeds. Larvae indicated by sawdust. It is an early ripening variety with high yields and good post-harvest handling potential. Glyphosate is a nonselective herbicide that is an effective control for both grasses and broadleaves. However, when trees or shrubs are transplanted into the landscape, stresses such as drought, soil compaction, sun scald, or injuries can weaken them and make them more susceptible to attack.
