Barricade Pre Emergent 1LTR

BARRICADE Pre-Emergent Herbicide contains 480 g/L prodiamine, sold in 250 mL, 1L and 5L packs. It is applied before weeds emerge and stops the listed weeds from germinating. The label lists established lawns and turf grass, garden beds (under mulch) and potted plants. Weeds named include crab grass, summer grass, barnyard grass, paspalum, rat’s tail fescue and winter grass, and in garden beds and pots also chickweed, creeping oxalis, cudweed and sow thistle. Signal word: CAUTION.

Where not to use it. The label says not to apply it in vegetable gardens or around fruit trees or sensitive plants, and not over the top of mulch. Do not apply to turf under stress, or to newly seeded, newly laid or sprigged turf: wait until the turf is at 100% cover with a root system developed beyond 3 cm. Do not apply to recently re-potted or newly potted seeds, cuttings, divisions or plants. Do not plant seeds in treated soil, replant any crop or ornamentals, or overseed with cool season grasses for 6 months after application. Do not let spray or drift contact recently planted or non-established plants or vegetable gardens.

How to use it. See the Application Rates tab. The label says to apply before weed emergence: in early spring for most weeds, and in late summer to early autumn for winter grass. On turf, lightly water in within 24 hours; on garden beds and pots, water in straight away with at least 3 mm of rain or irrigation. Do not apply if heavy rain is forecast within 48 hours or to waterlogged soil, and do not water to the point of run-off within 3 days. Do not graze treated turf or feed clippings from treated areas to poultry or livestock.

Before you buy. Wear safety glasses. Do not let containers or spray get into drains, sewers, streams or ponds. First aid is not generally required; if in doubt call the Poisons Information Centre on 13 11 26.
