Method for plant-protection treatment by leaf absorption, using a combination between an active ingredient and a modified oil and novel combination for using said method

Abstract

The subject of the invention is a method of plant-protection treatment by leaf absorption, characterized in that it uses a composition comprising at least one plant-protection active ingredient and at least one modified oil, a composition comprising at least one plant-protection active ingredient, at least one modified vegetable oil and at least one unmodified vegetable oil as well as an alkoxylated vegetable oil containing x% of glycerol.

What is claimed:  
     
         1 . Method of plant-production treatment by leaf absorption, characterized in that it uses a composition comprising at least one plant-protection active ingredient and at least one modified oil.  
     
     
         2 . Method as defined in  claim 1 , in which the composition used comprises at least one modified oil chosen either from ethoxylated and/or propoxylated oils, or from ethoxylated and/or propoxylated methyl, ethyl, linear or branched propyl, or linear or branched butyl esters of oils.  
     
     
         3 . Method as defined in  claim 1 , in which the composition used comprises at least one ethoxylated oil, or at least one ethoxylated methyl, ethyl, linear or branched propyl, or linear or branched butyl ester of oils, each having an EO value of between 1 and 50.  
     
     
         4 . Method as defined in  claim 1 , in which the composition used comprises at least one or more modified oils of plant origin chosen from modified sunflower, linseed, castor, soybean, corn, groundnut, copra, olive, palm, hydrogenated palm or rapeseed oils.  
     
     
         5 . Method as defined in  claim 4 , in which the composition used contains, in addition, a vegetable oil or a mixture of vegetable oils.  
     
     
         6 . Method as defined in  claim 1 , in which the active ingredient is a herbicide.  
     
     
         7 . Composition comprising at least one plant-protection active ingredient, at least one modified vegetable oil and at least one unmodified oil.  
     
     
         8 . Composition as defined in  claim 7 , in which the unmodified oil or the mixture of unmodified oils is of plant origin and is preferably chosen from sunflower, linseed, castor, soybean, corn, groundnut, copra, olive, palm, hydrogenated palm or rapeseed oils.  
     
     
         9 . Composition as defined in  claim 7 , in which the modified vegetable oil or the mixture of modified vegetable oils is chosen from ethoxylated and/or propoxylated vegetable oils, or from ethoxylated and/or propoxylated methyl, ethyl, linear or branched propyl, or linear or branched butyl esters of vegetable oils.  
     
     
         10 . Composition as defined in  claim 9 , in which the modified vegetable oil is an ethoxylated methyl ester having an EO value of between 1 and 4, more particularly equal to 1 or 2.  
     
     
         11 . Composition as defined in  claim 10 , in which the modified vegetable oil is at least one ethoxylated vegetable oil having an EO value of between 10 and 40 and more particularly greater than or equal to 15 and less than or equal to 30.  
     
     
         12 . Composition as defined in  claim 7 , in which the modified vegetable oil and the unmodified vegetable oil are derived from the same plant.  
     
     
         13 . Composition as defined in  claim 7 , in which the modified vegetable oil/unmodified oil weight ratio is between 1/50 and 50/1 and more particularly between 1/9 and 9/1.  
     
     
         14 . Composition as defined in  claim 7 , in which the modified oils are capable of being obtained by mixing, in the presence of a basic catalyst, from 1 to 10 parts of glycerol per 100 parts of unmodified oils, and then alkoxylating the resulting mixture.  
     
     
         15 . Composition as defined in  claim 7 , comprising at least one alkoxylated vegetable oil and at least one alkoxylated alkyl ester of a vegetable oil, more particularly comprising an ethoxylated and/or propoxylated methyl, ethyl, linear or branched propyl, or linear or branched butyl ester of a vegetable oil and one ethoxylated and/or propoxylated vegetable oil, and most particularly comprising an ethoxylated methyl ester of a vegetable oil having an EO value of between 1 and 4, and preferably equal to 1 or 2 and an ethoxylated vegetable oil having an EO value of between 10 and 40 and preferably greater than or equal to 15 and less than or equal 30.
