FORAGE AND ARABLE
Increasing lucerne yields with effective weed control Grass and broadleaf weeds are a serious threat to the quality and viability of a lucerne stand. Weeds can reduce the nutritional value of the crop and cause significant reduction in yield, as they compete aggressively for water, nutrients, sunlight and space. The grazing/cutting of lucerne encourages weed growth. Failing to control weeds will result in poor crop performance and shorten the productive life of a lucerne stand. Gramoxone 250 (plus atrazine) provides excellent knockdown and residual control of a wide range of grass and broadleaf weeds. Applied to lucerne annually during winter when the crop is dormant, Gramoxone 250 can increase lucerne yields by
up to 30 percent and extend the productive life of a stand by many years. Why use Gramoxone 250 for weed control in lucerne • Controls wide spectrum of grass and broadleaf weeds – one treatment covers most situations. • Activated by light – works well in cold winter conditions. • Tolerated by established (dormant) lucerne – removes weeds with minimal damage to lucerne. • Increases lucerne yield and nutritional value – premium payment for better quality feed. • Prolongs productive life of lucerne stands – good return on investment. • Rainfast within 20 minutes – less dependent on weather conditions. • 25 percent more concentrated than some paraquat formulations – more hectares treated per pack and less packaging.
recover quickly. It is inactivated on contact with the soil. Gramoxone 250 contains a blue dye for identification and a stenching agent to reduce the risk of accidental ingestion. Best use advice for Gramoxone 250 in lucerne • Remove all lucerne growth by hard grazing or close cutting before use. • Allow weeds to freshen up before application. • Apply 2.4 litres/ha of Gramoxone 250 during lucerne dormancy. • Add 1kg/ha atrazine (90 percent WG) on stands older than 12 months. • Apply only to clean, healthy weed foliage. • Avoid spraying when frost is on foliage.
What is Gramoxone 250
• Ensure total coverage of weeds.
Gramoxone 250 is a non-residual, fast acting, contact herbicide containing 250g/litre paraquat in the form of a soluble concentrate. Most grasses and broadleaf weeds are controlled by Gramoxone 250, although clovers
