Which is a chemical control used against weeds?

Explanation:
The key idea is recognizing chemical weed control, where a chemical herbicide is used to kill or suppress weeds. Atrazine is a herbicide, a chemical designed specifically to target and kill weeds, so it fits this role. It works by disrupting photosynthesis in susceptible plants, leading to their death. The other options are not chemical controls for weeds: mowing is mechanical and physically cuts plants; hand-picking insects is a manual pest control method for insects; Bacillus thuringiensis is a biological insecticide, not a weed killer.
