Delan Pro contains dithianon, a quinone multi-site contact fungicide with preventative activity. It affects a wide range of fungal enzymes by reacting with thiol groups and interfering with cellular respiration. The potassium phosphonate also boosts the tree's ability to fight scab delivering protection to all parts of new and expanding leaves.

Delan Pro can be used on all apple and pear varieties and provides disease protection against scab. The active ingredient, dithianon remains in the wax layer of the leaf to form a preventative barrier. Both active ingredients dithianon and phosphonic acid both act as preventative fungicides, inhibiting early stages of spore development prior to plant infection.

In the tissue of the plant, phosphonic acid also acts as an inducer of the plant’s natural defences.

In terms of application, Delan Pro should be applied from the start of bud burst prior to disease development and repeated at 5-10 day intervals, depending on disease pressure and seasonal weather conditions. A maximum of six applications of Delan Pro can be made each year.

Effective disease management is a critical component in delaying the build-up of resistant pathogen populations. Therefore, Delan Pro should be applied according to the recommendations for the target disease at the rate and timing as indicated on the product label.
