SLICK sprayer operators know that products applied at the right time give the best results.

But spring weather records show few ideal spraying days during the peak spraying period – in some years it is single figures. Making the most of those days can be helped greatly by careful planning of your refilling strategy.

Decide if you need bowser or back-at-base filling, or a combination. Ensure the water transfer pump has a sufficient rate and that the down load from a header tank is speedy but controlled. The water must be free of debris that may block the nozzles or filters.

Ensure you order chemical packs that can be safely and speedily handled by your filling system using an induction bowl and pack rinsing facility. For some products consider refillable packs, tablets or soluble sachet packaging.

Give your operator full and clear instructions and any necessary measuring equipment and protective clothing. This is required by law, but also ensures work is uninterrupted by queries. Also include the sequence for adding tank mix products.

Last, ensure the sprayer tank, booms and pipework are thoroughly rinsed after use. This prevents contamination and the risk of blocked pipes, filters or nozzles. &#42
