After being hit by paraquat, the leaves of corn have dried up and the stalks of corn are still green. Will corn die? Is there any good way to remedy it? Urgent. . .

Paraquat is a contact herbicide. As long as it comes into contact with corn, the contact part will suffer. Judging from the situation you described, the leaves are all dead, and they can't synthesize photosynthesis and provide nutrition for corn. It's basically hopeless. The corn stalk is still green, in fact, it is also a victim, but the corn stalk tissue is relatively thick, which has not been shown for the time being, and will show symptoms in the future. If the leaves are still green or slightly damaged, you can spray water to wash away some drug damage and save some corn.
