State officials said here today that they had authorized the spraying of the herbicide paraquat on marijuana fields in Florida. It would be the first domestic use of the weed killer to kill marijuana plants, according to the Federal Drug Enforcement Administration.

The spraying could begin as early as this week, or as soon as officers find a suitable field of marijuana, said Jim York, the state Law Enforcement Commissioner.

Gov. Bob Graham and Attorney General Jim Smith said they were convinced that paraquat spraying would be safe, arguing that the dead marijuana plants would not reach consumers.

''We'd keep the marijuana for evidence,'' Mr. York said, adding that sprayed fields would be monitored to prevent smugglers from harvesting the plants.
