A pyrethroid that kills adult weevils for about 7 days and kills larvae as they hatch from eggs. Make applications at least 7 days apart and do not release flood water within 7 days of application. Do not apply more than 1.1 pt (0.2 lb a.i.)/acre/season. If application is delayed until midsummer, notify your mosquito vector control district personnel so that they can monitor the mosquito fish population
