Previsan is a solution based on EM®, which allows it to be attached to the waxy layer of the leaves, thus maintaining the effectiveness of EM® over time.
Previsan creates a thin film on the plant. This acts as a physical barrier to protect against pathogens. This makes the plant less susceptible to damage from desease.
A whole new approach for the problem of black spot / honeydew mold is the removal of the honeydew before the fungus can settle. In other words making sure that the food source is gone before the fungus can arise. By developing a natural preparation based on microbiology, Agriton has succeeded in reducing the problem of honeydew to a minimum. Various practical applications in berries, apples and pears yielded very good results with regard to the elimination of honeydew. Which therefore also has a positive effect on preventing black spot.
Integrated approach: Simply removing the food source of the fungus instead of the targeted killing of the primary cause (lice, psyllids) or the secondary cause (the fungus), is a fairly unique approach. But it fits perfectly in the integrated cultivation.
By developing a natural preparation based on microbiology, Agriton has succeeded in reducing the honeydew problem to a minimum. In an official trial conducted by CAF, Previsan significantly reduced the pear psylla secretion. Various practical applications in berries, apple and pear gave a very good result on the elimination of honeydew and therefore also a positive effect on the prevention of sooty mold.
The principle of not specifically killing the infestation (lice, psyllid) or killing the secondary cause (the fungus) but simply removing the food source for the fungus is quite unique but fits perfectly within integrated cultivation.
