The following are just a few of the most common weeds controlled with broadleaf herbicide this time of year. A good rule of thumb for herbicide application would be broadleafs in the cooler months, grassy in the warm months, however, most broadleafs respond to chemical application no matter the time of year, they are easier to kill, have more leaf blade surface for the chemical to adhere to and less of a fibrous root system.
Common Weeds Not Treated Until Warm Temperatures Rise Consistently, which unfortunately is most if not all grassy weeds, consistent 90-degree temperatures or hotter is best for chemical application performance. Sedge grasses are the most difficult to control because of their narrow blade surface, lateral root system and persistent nature

White grubs eat organic matter including the roots of plants. Therefore, damage first appears to be drought stress. Heavily infested turf appears off color, gray-green, and wilts rapidly in the hot sun. Continued feeding will cause the turf to die in large irregular patches. The tunneling of the larvae cause the turf to feel spongy under foot and the turf can often be rolled back like a loose carpet. Once the damage is done, its hard to regain any new turf without sodding or seeding. The best alternative to damage is preventative grub insecticide, however, topical insecticide can be applied once grubs have reached mature stages to kill on contact, preventing any further damage from occurring. Often grubs are found in soft soils or healthy lawns near and around street lamps or outdoor lighting.
