Use of acylsulfonamides for improving plant yield

Abstract

Compounds (A) can be used for increasing the yield of useful plants or crop plants with respect to their harvested plant organs, wherein the Compound (A) is selected from compounds of the formula (I) or salts thereof, wherein the symbols are defined as in claim 1, preferably cyprosulfamide [Compound (A1)].

1 . A method for inducing a growth regulating response in a plant, in which the plant grows in a normal habitat, thereby increasing the yield of such plant,
 wherein the plant is selected from the group consisting of cereal, canola, soybean, and cotton;   wherein the composition comprises (a) cyprosulfamide or (b) cyprosulfamide and a fungicide selected from the group consisting of (i) tebuconazole, (ii) epoxiconazole and (iii) difenoconazole;   wherein the composition is applied in a non-phytotoxic amount with respect to the plant being treated,   wherein the cyprosulfamide is applied in a range of from 25 g to 100 g active substance per hectare and the fungicides (i), (ii), or (iii) when present are applied in a range from 125 g to 375 g active substance per hectare.   
     
     
         2 . The method as claimed in  claim 1 , wherein the compositions is applied in combination with one or more compounds selected from insecticides or plant growth regulators. 
     
     
         3 . The method as claimed in  claim 1 , wherein the composition comprises (a) cyprosulfamide as the only agriculturally active component. 
     
     
         4 . The method as claimed in  claim 1 , wherein the composition comprises (a) cyprosulfamide and (i) tebuconazole as the only agriculturally active components. 
     
     
         5 . The method as claimed in  claim 1 , wherein the composition comprises (a) cyprosulfamide and (ii) epoxiconazole as the only agriculturally active components. 
     
     
         6 . The method as claimed in  claim 1 , wherein the composition comprises (a) cyprosulfamide and (iii) difenoconazole as the only agriculturally active components. 
     
     
         7 . The method according to  claim 1 , wherein the plant is wheat or corn. 
     
     
         8 . The method according to  claim 1 , wherein the applying is to a plant, a seed from which the plants grows, and/or or locus in which the plants grows, wherein the treated plant is not under disease pressure. 
     
     
         9 . The method according to  claim 1 , wherein the applying is to a plant, a seed from which the plants grows, and/or or locus in which the plants grows seed, wherein the treated plant grows in the absence of abiotic stress conditions. 
     
     
         10 . The method according to  claim 1 , wherein the applying is to a plant, a seed from which the plants grows, and/or or locus in which the plants grows, wherein the treated plant grows in the absence of extraordinary environmental conditions.
