SUMMA® CONTACT is a fertilizer product formulated with highly soluble chelated manganese.
The components present in the composition of SUMMA® CONTACT favor adhesion on the plant surface, increasing persistence and reducing product losses due to runoff. SUMMA® CONTACT also favors the anti- rebound action of the spray droplets and the increase of the wetting surface, achieving a greater coverage of the treatment on the leaf and a homogeneous distribution of the treatment.
The application of SUMMA® CONTACT is indicated to retain the manganese present in its composition on the plant surface for a longer period of time and in greater quantity. These effects can be extended to other products included in the application tank, which will benefit from the mode of action of SUMMA® CONTACT maximizing the effects of the treatment.
