NOVEL PESTICIDE AND OR GROWTH REGULATING COMPOSITIONS WITH PARTICULAR NON IONIC SURFACTANT.

摘要

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.
