Question

Which of the following herbicide sites of action is/are only used for non-selective control of emerged weeds?

a) Inhibitors of cell division.
b) Photosystem II inhibitors.
c) Lipid synthesis inhibitors.
d) ACCase inhibitors.

Answer 1

Only lipid synthesis inhibitors are used for non-selective control of emerged weeds among the options listed.

Step-by-step explanation:

The question pertains to the site of action for herbicides that are only used for non-selective control of emerged weeds. Non-selective herbicides are designed to kill all plant material they come into contact with, as opposed to selective herbicides, which target specific weeds while leaving the desired crop relatively unharmed. Among the herbicide sites of action listed, lipid synthesis inhibitors are generally known to be non-selective and are used to control a wide range of plant species. Hence, the correct answer to the question is c) Lipid synthesis inhibitors.
