摘要:
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.
摘要:
The invention relates to a process for the phosphatization of metallic substrates comprising the use of a phosphatization bath having a pH from 1 to 5.5 and which comprises from about 0.3 to about 25 g/l of zinc ion, preferably from 0.5 to 10 g/l, from 5 to about 50 g/l of phosphate ion, preferably from 8 to 30 g/l, and from about 0.01 to about 10 g/l, preferably from 0.03 to 3 g/l of a trivalent cobalt complex.
摘要:
The invention relates to a composition, which is simultaneously anticlumping and water-repellent, for salts, simple and complex fertilizers. This composition contains: on the one hand, an anticlumping product chosen from fatty amines, amine salts of phosphoric esters, amine salts of alkylarylsulphonic acids and mixtures thereof, and on the other hand, an anticlumping substance capable of imparting water-repellent properties and consisting of the product of the reaction of an alcohol or an amine with a carboxylic acid or anhydride bearing a hydrocarbon group having from 20 to 500 carbon atoms, as well as a formulation agent.
摘要:
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. The said granular herbicidal composition is obtainable by use of a process according to which aminotriazole, alone or as an intimate homogeneous mixture with at least one other herbicide of the above-identified group, is, if necessary, brought by milling to a suitable particle size, mixed with an amount of water sufficient to ensure its cohesion under a moderate pressure, optionally brought together with a surface-active agent and directed through the orifices of the grid of an extrusion device, the granules of cylindrical shape thus obtained being dried.
