Water-dispersible agrochemical compositions

Abstract

The invention relates to novel compositions of biologically active agents containing less than 50% by weight of a low use rate agrochemical active and a dispersing agent, which exhibit enhanced bio-availability on dilution and application in water.

         59 . A method for using a composition to treat a plant or a locus of the plant, the method comprising the steps of:
 selecting a primary agrochemical active ingredient from metsulfuron-methyl, nicosulfuron, rimsulfuron, tribenuron methyl, thifensulfuron-methyl, chlorsulfuron, bensulfuron-methyl;   selecting a secondary agrochemical active ingredient from diuron, linuron, metribuzin, oxyfluorfen and propanil;   providing a dispersing agent;   extruding a mixture to form a composition wherein the mixture has the primary agrochemical active ingredient, the secondary agrochemical active ingredient and the dispersing agent wherein the primary agrochemical active ingredient is present at a level of less than 10% of weight of the composition wherein the secondary agrochemical active ingredient is present at a level of more than 50% by weight of the composition; and   applying a herbicidally effective amount of the composition to the plant or to the locus of the plant to be treated.   
     
     
         60 . The method according to  claim 59  wherein the primary agrochemical active ingredient is applied to the plant or the locus of the plant at a rate of use of less than 50 g/hectare wherein the secondary agrochemical active ingredient is applied to the plant or the locus of the plant at a rate of use of less than 7000 g/hectare.
