Blaster Selective Herbicide

Blaster is a foliar-acting selective herbicide that controls perennial broad-leaved weeds in established amenity grassland, including nettles, docks, thistles, brambles, broom and gorse, plus some woody weeds.

Directions for use

Overall treatment on amenity grassland: 2-4 litres/ha. Timing matters: apply while weeds are actively growing for the best results.

Spot treatment

Where weed populations are too low to justify overall spraying, mix 60ml of Blaster in 10 litres of water. Coat the weeds thoroughly with the spray solution, but stop before run-off, as this reduces how well it works.

Restrictions and precautions

• Use only on permanent grassland that has been established for at least one year.
• Do not apply overall where clover is an important part of the sward: Blaster will kill it.
• Do not spray in drought, or in very hot or very cold conditions.
• Avoid damage and drift onto susceptible crops or waterways. Conifers, especially pine and larch, are very sensitive to spray drift.

Some yellowing of the sward can occur after treatment. This is usually outgrown quickly.

Rainfast period and mowing

Leave a 24 hour dry period after application so the actives can stick to the target plant. Do not mow for at least 3 days following application.
