Optimising ProClova XL application for maximum dock control

ProClova XL will provide 'susceptible' levels' of control, ranging from 85% to 100% when assessed at the end of the season, based on docks present at the time of spraying. To maximize results, key factors such as leaf area, health, and active growth must be considered.

Several factors can impact the level of control achieved, including:

• Disease and pests: such as ramularia and dock beetles
• Cold temperatures (below 8°C) or excessively dry conditions, which inhibit active growth. Wait for better weather conditions and signs of growth before spraying.
• Spraying too soon after cutting, when leaves are too small compared to the root size
• Spraying docks that have started flowering or those with many older, less active leaves
• Overcrowding, where too many docks may prevent proper spray coverage or shading by excess grass

Topping and spraying dock re-growth once it reaches the optimal size can improve control, especially when these factors are present. This ensures uniform plant size and leaves free from disease or dock beetle damage.

How to optimise ProClova XL application using drift reducing technology 

Air inclusion nozzles are an effective solution to reduce drift. They create larger droplets filled with small air bubbles, resulting in a coarser spray that travels accurately from the nozzle to the target. Upon impact, the droplets burst, distributing smaller droplets evenly across the leaf surface, ensuring better product deposit and reduced drift.

The choice of nozzle depends on travelling speed and water volume:

• ProClova XL requires 200 liters of water per hectare for application.
• Optimal spraying speed for grassland is typically between 8 to 10 kph, depending on field conditions.

Refer to the table below for nozzle options based on these parameters.
 

Speed of action on docks

When controlling docks, ProClova XL will work more slowly compared to other Corteva grassland products. For optimal results, patience is key—allow time for the full effects to show.

Controlling docks emerging from root fragments

Docks that emerge from root fragments in a previous grass ley are more challenging to control compared to those emerging from seed. If large, established populations of docks exist in the preceding ley, consider applying ProGrass or Doxstar Pro, 6 weeks before sowing.

Hard water and use of water conditioners

When using a water conditioner, choose an acidifying water conditioner when applying ProClova XL. In areas with hard water, water conditioners can help soften the water and prevent the herbicide from binding to hard water cations. Avoid using ammonium sulfate-based conditioners, as they may have additional adjuvant properties that could compromise clover safety.

Guidance on thistle control where clover is present

ProClova XL does not control thistles. The most effective option for managing thistles in areas with clover is to spot spray with Grazon Pro.
