Which of the following is not a common method of integrated management of aquatic weeds?

Demolition is not a common method of integrated management of aquatic weeds because it typically involves the destruction of structures or habitats rather than directly addressing weed control. In contrast, physical removal, herbicides, and biological control methods are specifically aimed at managing and controlling aquatic weed populations.

Physical removal involves manually or mechanically extracting weeds, which can be effective in small areas where targeted intervention can occur. Herbicides are chemical agents designed to selectively control or eliminate unwanted vegetation, making them a prevalent choice in integrated pest management strategies. Biological control utilizes natural predators or competitors to reduce weed populations, which can provide a sustainable and environmentally friendly approach to managing aquatic weeds.

The goal of integrated management strategies is to combine multiple techniques to effectively control weed populations while minimizing environmental impact, which demolition does not contribute to.
