Novel pesticidal and/or growth-regulating compositions comprising a specific nonionic surface-active agent

摘要

Pesticide and/or growth regulating compositions for plants is disclosed, wherein the composition comprises: A) one or more pesticidal and/or growth regulating active materials for harmful plants, insects or animals, with the exception of diniconazole; B) a specific nonionic surfactant comprising two different chemical components: 1) whereof the molecular mass ranges between 200 and 3000 g/mol; 2) whereof the dynamic tension, measured in water, at a concentration of 0.4 g per liter at a frequency of 10 Hz, ranges between 35 and 73 mN/m; 3) and each chemical component comprising: 3(i) a hydrophobic part selected among the C13 oxo alcohol groups; isodecyl-isodecyl-hydroxy alcohol; C12-C14 linear alcohols; C16-C18 linear alcohols; lauryl alcohol; myristic alcohol; do-and/or tetradecanols; distyrylphenol-di(1-phenylethyl) phenols; nonylphenols; acetylenediols; tri-decyclic alcohols; and whereof the molar mass ranges between 100 and 1500 g/mol; 3(ii) a hydrophilic part selected among a poly(oxy-1,2-ethanediyl) radical and a poly(oxy-1,2-propanediyl) radical, whereof the molar mass ranges between 80 and 2000 g/mol; 4) the difference in molar mass of the hydrophobic parts of said two chemical components is less than 140 g/mol; and that 5) the difference in molar mass of the hydrophilic parts of these two chemical components is less than 360 g/mol.
