Anti Drift


Maximise fungicide performance

Keeping late blight out of potatoes is a season long campaign for growers and becoming increasingly challenging. With resistance to fluazinam and the increased pressure on remaining modes of action, a robust resistance management strategy which improves coverage is essential to safeguard crops and chemistry. Developed to help tackle the practical problems growers face, Crusade is a flexible anti-drift agent specifically designed for use with all potato blight fungicides to reduce drift and maximise coverage to all parts of the crop.



Designed purely to reduce drift and maximise coverage

Key situations in which to use Crusade

  • With all blight fungicides throughout the programme to reduce drift and maximise coverage to all parts of the crop
  • Where on-time application is hard to achieve due to drift constraints
  • High blight risk and need to maximise protection throughout the whole crop

Maximising performance

Key benefits

Maximises fungicide dose on the crop

Drift is the biggest cause of off-target chemical movement and threatens the crop from disease where it is not adequately protected. Crusade reduces drift which in turn ensures the full intended dose is delivered to the whole crop in order to maximise fungicide performance.

Crusade aids coverage to the lower canopy

Whilst full crop coverage is vital to prevent scattered infection, the "umbrella-like" structure of the canopy - a series of interlocking leaves - makes this very difficult to achieve. Leaves are good collectors of vertical moving spray in the upper canopy but leaves and stems lower down can be very hard to reach, moving the risk of tuber blight to the whole crop. The addition of Crusade to fungicide sprays manipulates droplet size to maximise coverage (and dose) to both the upper and lower canopy.

Extends the spray window

By reducing drift, Crusade can ensure blight sprays can still be applied to the crop.

Value in use

Crusade delivers maximum protection against blight

By delivering the full intended fungicide dose to the crop, Crusade offers stronger protection against blight, in situations where it otherwise would have been compromised by drift.

Crusade prevents scattered infection

Crusade creates larger droplets helping blight fungicides to penetrate through to the lower canopy, thereby protecting the whole crop. Protecting the whole crop from scattered infection is essential to prevent the risk of blight to the entire crop.

Tightens spray intervals

Tight spray intervals are crucial to protect the crop. Crusade can make conditions conducive to spraying by reducing drift, that otherwise may not have been possible.

How Crusade works


Reduces spray drift

Crusade creates droplets more capable of reaching the upper and lower canopy and significantly reduces the number of fine spray droplets, smaller than 100 microns, that are the most susceptible to drift. In turn, this effect increases the spray angle uniformity at the nozzle, helping to ensure the correct dose is applied to the target. The addition of Crusade to fungicide sprays therefore helps to optimise coverage to all parts of the crop canopy, preventing scattered infection and ensuring maximum protection to the whole crop.

Keeping blight out with help from Crusade

Having recommended Crusade for the past three seasons, Agrii agronomist John Mason is going a step further and plans to apply all potato blight sprays with the drift retardant this year.

Prepare for changing pressures with Crusade

When, the time comes to start blight control, John Sarup of Spud Agronomy says he will be teaming his treatments with Crusade – an anti-drift agent that helps to remove the barriers that stop blight fungicides performing to their true potential.

Crusade kept us spraying

For grower Mike Dagg of Crailing Tofts near Kelso in Roxburghsire, there's no doubt Crusade has an important place in the blight control programme.
