Water-dispersible pellets containing a isobutylene diurea and a lignin binder

A water-dispersible particle comprising:

• an isobutylidene diurea present in an amount ranging from 5% to 99.9% by weight of the total dry weight of the particle;
• and
• a lignin derivative binder component, present in an amount ranging from 1% to 95% by weight of the total dry weight of the particle, the particle having a mean particle domain size from 0.1 millimeter to 30 millimeters;
• the pellet dried such that the isobutylidene diurea and the binder component are present in a form such that contact with water causes particle dispersion into more than 100 pieces;
• a biostimulant;
• wherein the biostimulant is selected from the group consisting of:
• a cytokinin, an auxin, a gibberellin, ethylene and absisic acid, and a combination thereof.

A process for making a water-dispersible particle comprising:

• (a) mechanically aggregating into a pellet:
• isobutylidene diurea present in an amount ranging from 5% to 99.9% by weight of dry weight of the particle and
• a lignin derivative binder component, present in an amount ranging from 1% to 95% by weight of the total dry weight of the particle;
• said particle having a mean particle domain size from 0.1 millimeter to 30 millimeters, the isobutylidene diurea and the binder present in a form such that contact with water causes particle dispersion into more than 100 pieces;
• and
• (b) drying the pellet.
