General Instructions

General Information

BASAGRAN is a selective contact herbicide that must be applied in sufficient water to ensure that all parts of the target weeds are thoroughly covered. Immature weeds (2 - 4 leaf) are more readily controlled than more mature plants. BASAGRAN is especially effective against chamomiles, stinking mayweed, cleavers, storksbill and Onehunga weed. Other broadleaf weeds controlled include redroot (Prince of Wales feather), chickweed, black nightshade, spurrey, shepherds purse, thorn apple, and wild turnip. BASAGRAN is not active in the soil, so weeds must have germinated before spraying (post emergence).


  1. Wetting agents should not be added unless specified.
  2. At least 8 hours should elapse after application before rainfall or irrigation.
  3. Use high water rates (minimum rates specified). Low volume CDA application techniques are not recommended.


Do NOT carry this product on a passenger service vehicle.
