Abstract: Ethephon-based composition for the regulation of plant growth containing in addition to ethephon, at least one product or adjuvant the chemical structure of which contains at least two acid functions selected from carboxylic acid type of formula (--COOH) and phosphonic acid type of formula (--PO.sub.3 H.sub.2), at least one of these acid functions being the (--PO.sub.3 H.sub.2) function.

Abstract: Granular herbicidal water-soluble composition based either on aminotriazole alone or on aminotriazole combined with at least one other herbicide selected from the group comprising alkaline, alkaline-earth metal and ammonium thiocyanates, glyphosate, MCPA sodium salt, sulfosate, glufosinate, paraquat and metribuzen. It is provided in the form of granules of cylindrical shape, with a composition and a diameter which are substantially identical from one granule of cylindrical shape to another for a given granular herbicidal composition, the diameter and the length of the said granules of cylindrical shape being respectively of the order of 0.4 to 2 mm, preferably of 0.8 to 1.4 mm, and of the order of 5 to 10 millimeters.
