Casoron is classified under which major mode-of-action group?

Casoron, also known by its active ingredient, dichlobenil, is classified under the major mode-of-action group of seedling growth inhibitors. This classification is based on its ability to interfere with the normal growth processes of seedlings, preventing them from developing further once germination has occurred.

Seedling growth inhibitors work by targeting the early stages of plant development, specifically disrupting cell division and elongation, which results in the stunting or killing of young plants. This mode of action is particularly effective in controlling annual weeds and certain perennial weeds, as it disrupts their growth before they establish themselves.

In contrast, selective herbicides act on specific types of plants while leaving others unharmed; systemic herbicides are absorbed by the plant and translocated throughout its tissues; and soil sterilants work to kill all vegetation and render the soil unable to support plant life for an extended period. These other categories do not reflect the specific action of Casoron, which primarily inhibits seedling growth.
