AGRICULTURAL AGENT APPLICATOR, METHODS FOR TREATING WEED HERBS OR CROPS FOR APPLYING AGRICULTURAL AGENTS AND TO CONTROL PARASYLY WEED HERBS. Acetolactate synthase inhibitors, such as imazapyr and piritiobac and mixtures thereof, prepared as slow release formulations, are useful for preparing herbicidal particle, seed, seed base layer or seed cover for herbicide compositions. parasitic weeds such as Orobanche spp., Striga spp. and Alectra spp. The use of agrochemicals can be made more effective when they are coated or bonded as a slow release formulation. Particles used as the substrate to be coated may be plant seeds or particles made of a strong or weak ionic resin or a biodegradable natural carbohydrate polymer, a modified polymer or articulically lignified cellulose. The herbicidal formulation may be covalently bound or adsorbed to the surface of the particle. The same slow release formulations are invaluable for preventing rapid herbicidal leaching in non-agricultural weed control situations.
