pesticidal and / or growth regulating compositions of harmful plants and / or insects and / or animals, non-ionic surfactant, crop treatment and / or protection process, public hygiene treatment and / or protection process or Household and wetting process.
The invention concerns pesticide and/or growth regulating compositions for plants containing a particular non-ionic surfactant comprising two different constituents: 1) whereof the molecular mass ranges between 200 and 3000 g/mol, preferably between 300 and 1000 g/mol； 2) whereof the dynamic tension, measured in water, at a concentration of 0.4g per litre at a frequency of 10 Hz, ranges between 35 and 73 mM/m； 3) and each 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-(phenyl-1-ethyl) phenols； nonylphenols； acetylene diols, in particular tetra-(methyl-2,4,7,9)-deca-5-yne； tri-decyclic alcohols； and whereof the molar mass ranges between 100 and 1500 g/mol, preferably between 150 and 400 g/mol； 3(ii) a hydrophilic part selected among a poly-(oxy 1,2 ethanedi-yl), whereof the molar mass ranges between 80 and 2000 g/mol, preferably between 100 and 900 g/mol； 4) the difference in molar mass of the hydrophobic parts of said two chemical constituents is less than 140 g/mol； 5) the difference in molar mass of the hydrophilic parts of said two chemical constituents being less than 360 g/mol. The invention also concerns the non-ionic surfactant.
