Combination of pethoxamid and picloram

Abstract

Presented is a composition comprising pethoxamid and picloram. The composition exerts a synergistical effect.

1 . A method for controlling harmful plants comprising exposing the harmful plants to a synergistically effective amount of a combination of, as component A) pethoxamid, and as component B) picloram and agriculturally acceptable derivatives thereof. 
     
     
         2 . The method according to  claim 1 , wherein the harmful plants are present together with useful plants. 
     
     
         3 . The method according to  claim 1 , wherein the combination is applied before, during and/or after emergence of the harmful plants, where component A and component B are applied jointly or separately, simultaneously or in succession. 
     
     
         4 . The method according to  claim 3  wherein components are combined prior to application and applied jointly from the same container. 
     
     
         5 . The method according to  claim 3  wherein the components are applied from separate containers. 
     
     
         6 . The method according to  claim 1 , wherein useful plants are present together with the harmful plants and the useful plants are selected among the group consisting of cereals, oilseed rape, corn, soybeans, and cotton. 
     
     
         7 . The method according to  claim 1 , comprising employing a combined application rate of component A and component B of 0.05 to 3 kg/ha. 
     
     
         8 . The method according to  claim 1 , comprising employing from 0.05 to 2.5 kg/ha of component A and from 0.001 to 1 kg/ha of component B. 
     
     
         9 . The method according to  claim 1 , wherein the weight ratio of component A:B ranges from 1:1 to 500:1. 
     
     
         10 . The method according to  claim 1 , wherein the picloram is present, in part or in total, as the dimethylammonium-salt, the triethylammonium salt, the triisopropanolammonium salt, the isoctyl ester (isooctyl) and the potassium salt; and mixtures thereof. 
     
     
         11 . A herbicidal composition comprising a combination of, as component A) pethoxamid, and as component B) picloram and agriculturally acceptable derivatives thereof. 
     
     
         12 . The composition according to  claim 11  comprising at least one solid or liquid carrier and/or one or more surfactants. 
     
     
         13 . The composition according to  claim 11 , wherein component A and component B is present in a form selected from the group consisting of ready-to-use solutions, emulsifiable concentrates, emulsions, suspensions, wettable powders, soluble powders, granules, soluble granules, dispersible granules, micro-emulsions, microcapsule suspensions, and mixtures thereof. 
     
     
         14 . The composition according to  claim 11 , wherein the weight ratio of compounds A:B ranges from 1:1 to 500:1. 
     
     
         15 . The composition to  claim 11 , wherein the picloram is present, in part or in total, as the dimethylammonium-salt, the triethylammonium salt, the triisopropanolammonium salt, the isoctyl ester (isooctyl) and the potassium salt; and mixtures thereof.
