Abstract
An attrition and shatter resistant plant nutrient/pesticide briquette composition which slowly releases the nutrients and biologically active materials over long periods of time, comprising slow release plant nutrient particles, pesticide sorption particles, liquid systemic pesticide sorbed on the pesticide sorption particles to reduce pesticide leachability, an adhesive, coating the slow release plant nutrient and pesticide sorption particles, the composition formed into briquettes by pressing into dies at elevated pressures and temperatures to make briquettes resistant to attrition and shattering. A six step method is provided for the preparation of the slow releasing briquettes from slow release fertilizers, such as magnesium ammonium phosphate; pesticide sorption particles, such as activated carbon; liquid systemic pesticides emulsions, such as imidachloprid fosetyl-Al, and metalaxyl; and adhesives, such as a vinylidine chloride, 2-ethylhexyl acrylate, acrylic acid resin emulsion.
