True or False: Perennial grasses and weeds are more easily controlled than annual weeds and grasses with preemergence herbicides.

The statement is false because perennial grasses and weeds tend to have more established root systems and greater vigor than annuals. This resilience allows them to survive various control measures, including preemergence herbicides, which are designed to prevent the germination of seeds.

Preemergence herbicides are more effective against annual weeds, as these plant types germinate from seeds and are susceptible to these herbicides before they sprout. In contrast, perennials can regenerate from their root systems even after herbicide application, making them more difficult to manage using this method.

Therefore, the assertion that perennial grasses and weeds are more easily controlled than annual weeds and grasses with preemergence herbicides is not accurate, solidifying the choice as false.
