A Concentrated herbicide formulation, non-volatile, Low Temperature, stable water soluble acid and 2,4-d (2,4-dichlorophenoxy acetic)

摘要

A Concentrated herbicide formulation, not volatile, stable at low temperatures and water soluble acid (2,4-d (2,4 - diclofenoxi) acetic acid), characterized in that it comprises: 45 to 75% w / V, 2,4-d acid, in the form of a water-soluble Amine Salt of primary, secondary or Tertiary or Lcanolamina Primary, secondary or Tertiary, or mixture of both; 1 to 40% w / VA Wetting Agent selected from the group consisting of the oxides of Amine, amide, Amine oxides, ethoxylated Fatty amines and their Derivatives, Glycerin, sorbitol and polyethylene glycol and its derivatives, and mixtures thereof; 0.1 to 20% w / V, selected from the group consisting of an ANTIFREEZE Glycols; 0.01 to 0.5% w / VAn antifoam Agent chosen from Emulsions of silicone oils to 10 - 30%, hydrocarbon based Surfactants, such as fatty acids and their salts in Hydrocarbon alcohols with 8 or more carbon ATOMS, such as 2 - etilehexanol and isooctanol; option At present, 0.5 - 10% w / V, a nonpolar Solvent, and the remainder being Water.2,4-d is a selective Herbicide for the dicotyledons is presented as soluble Concentrate of this compound in the form of its Alkali salts, ammonium salts are not volatile Amine or alkanolamine or emulsifiable concentrates of acid Esters of 2,4-d or BA High Ja volatility.It has been found that, in terms of penetration into the leaves, esters of 2,4-d are more effective than amines although its herbicidal effect is slower. On the contrary, amines possess a herbicidal Effectiveness more rapid but less effective than Esters Esters in the ease of Absorption on the leaves.However, the Amine salts have the advantage of not be volatile, eliminated, therefore, the risks posed by Drift and volatility Esters that could cause damage to sensitive crops.These formulations of 2,4-d acid, based on their Amine salts solved the problems presented by these salts, in terms of its power of penetration, with the addition of specific adjuvants that enhance the performance of the active Compound herbicide and, Furthermore, allow Automatic Hoist such formulation to temperatures of - 8 + or - 2 degrees Celsius.
