Introduction

Postemergence - Leaf stage of the weeds is critical for good weed control. Smaller weeds are generally easier to kill but there needs to be enough leaf surface to intercept the herbicide. Apply according to recommended leaf stages. Crop stage is important to optimize crop safety. Adjuvants will frequently improve the weed control when used as directed. Weather or other conditions may influence the optimum rate of adjuvant, see the product label for more details. Always use appropriate drift management technology.

Precautions

• Apply in 1000 L/ha water (400 L/ac).
• For spot spraying, apply 55mL Gramoxone/10L water sprayed to wet weed foliage.
• Direct spray at base of canes in the spring before new shoots emerge.

• Apply as a directed spray to established plantings.
• Do NOT spray young raspberry shoots.
• Use 1000 L/ha water (400 L/ac) to wet weed foliage.

Precautions

• For use in the production year of raspberries grown in the biennial production system, or in a planting that will be removed after harvest.
• Do NOT apply to immature and weak plantings.
• Apply when shoots are 10-20 cm tall to suppress the emerged flush of primocanes, and control any weeds emerged at time of treatment.
