Directions for use

Best results are obtained by choosing the most suitable method of application, beginning before the effects of disease are seen. Do not apply under hot sunny conditions, during frost or when rain is imminent or falling.

Under conditions of high disease risk and where a choice of rate is shown, use the higher rate.

It may also be necessary to use the shorter spraying intervals. Use the lower rate on young plants or on sensitive species or varieties.

For soil borne disease control apply as a drench.   Use high volume sprays to control aerial diseases.


Ensure sufficient volume is used to thoroughly drain through the growing medium. The quantity should be adjusted according to the compost type, depth and moisture level.


Efficient coverage of the target area is essential. Use a penetrative application and ensure sufficient volume is used to obtain thorough wetting but do not spray beyond run-off. A medium or coarse quality spray (BCPC definition) is recommended.
