Method for controlling coniferous plants

Abstract

A method for controlling coniferous plants, in particular naturally seeded coniferous plants (wildling conifers), wherein an effective amount of at least one herbicide selected from the group consisting of sulfentrazone, carfentrazone, their agriculturally acceptable salts and their agriculturally acceptable derivatives is applied to the coniferous plants to be controlled or to their parts, such as roots, leaves, seeds or germinants.

We claim:

 A1 acetolactate synthase inhibitors (ALS inhibitors);   A2 photosynthesis inhibitors;   A3 enolpyruvyl shikimate 3-phosphate synthase inhibitors (EPSP inhibitors);   A4 glutamine synthetase inhibitors;   A5 auxin herbicides; and   A6 fosamine, and   at least one further herbicide B, which is selected from the group consisting of sulfentrazone, carfentrazone, their agriculturally acceptable salts and their agriculturally acceptable derivatives,   except for compositions which comprise at least one herbicide A selected from chlorimuron, halosulfuron, metsulfuron, nicosulfuron, primisulfuron, prosulfuron, thifensulfuron, tribenuron, imazamethabenz, flumetsulam, pyrithiobac, atrazin, difenzoquat, paraquat, bromoxynil, pyridate, glyphosate, glufosinate, 2,4-D, MCPA, dicamba, clopyralid, fluoxazine, the agriculturally acceptable salts thereof and the agriculturally acceptable derivatives thereof, and carfentrazone, an agriculturally acceptable salt thereof or an agriculturally acceptable derivative thereof, and   except for compositions which comprise at least one herbicide A selected from chlorimuron, rimsulfuron, tribenuron, imazethapyr, cloransulam, flumetsulam, metribuzin, qlyphosate, 2,4-D, the agriculturally acceptable salts thereof and the agriculturally acceptable derivatives thereof, and sulfentrazone, an agriculturally acceptable salt thereof or an agriculturally acceptable derivative thereof.   
     
     
         2 . The composition as claimed in  claim 1 , wherein herbicide A is selected from imazapyr, its agriculturally acceptable salts and its agriculturally acceptable derivatives. 
     
     
         3 . The composition as claimed in  claim 1 , wherein herbicide B is selected from carfentrazone, its agriculturally acceptable salts and its agriculturally acceptable derivatives. 
     
     
         4 . The composition as claimed in  claim 1 , wherein herbicide A is selected from the group consisting of metsulfuron and sulfometuron, their agriculturally acceptable salts and their agriculturally acceptable derivatives and wherein herbicide B is selected from sulfentrazone, its agriculturally acceptable salts and its agriculturally acceptable derivatives. 
     
     
         5 . The composition as claimed in  claim 1 , wherein herbicide A is selected from the group consisting of cyanazine, hexazione and diuron, their agriculturally acceptable salts and their agriculturally acceptable derivatives, and wherein herbicide B is selected from carfentrazone, its agriculturally acceptable salts and its agriculturally acceptable derivatives. 
     
     
         6 . The composition as claimed in  claim 1 , wherein herbicide A is selected from the group consisting of atrazine, cyanazine, hexazione, diuron, bromoxynil and paraquat, their agriculturally acceptable salts and their agriculturally acceptable derivatives, and wherein herbicide B is selected from sulfentrazone, its agriculturally acceptable salts and its agriculturally acceptable derivatives. 
     
     
         7 . The composition as claimed in  claim 1 , wherein herbicide A is glufosinate an agriculturally acceptable salt or an agriculturally acceptable derivative thereof, and wherein herbicide B is selected from sulfentrazone, its agriculturally acceptable salts and its agriculturally acceptable derivatives. 
     
     
         8 . The composition as claimed in  claim 1 , wherein herbicide A is selected from the group consisting of dicamba, aminopyralid, clopyralid, fluroxypyr, picloram and triclopyr, their agriculturally acceptable salts and their agriculturally acceptable derivatives, and wherein herbicide B is selected from sulfentrazone, its agriculturally acceptable salts and its agriculturally acceptable derivatives. 
     
     
         9 . The composition as claimed in  claim 1 , wherein herbicide A is selected from the group consisting of aminopyralid, picloram and triclopyr, their agriculturally acceptable salts and their agriculturally acceptable derivatives, and wherein herbicide B is selected from cartentrazone, its agriculturally acceptable salts and its agriculturally acceptable derivatives. 
     
     
         10 . The composition as claimed in  claim 1 , wherein herbicide A is fosamine. 
     
     
         11 . The composition as claimed in  claim 1 , wherein herbicide A is selected from the group consisting of metsulfuron, sulfometuron, imazapyr, hexazione, paraquat, glufosinate, dicamba, aminopyralid, clopyralid, picloram, triclopyr and fosamine their agriculturally acceptable salts and their agriculturally acceptable derivatives, and wherein herbicide B is selected from sulfentrazone, its agriculturally acceptable salts and its agriculturally acceptable derivatives. 
     
     
         12 . The composition as claimed in  claim 1 , wherein herbicide A is selected from the group consisting of sulfometuron, imazapyr, hexazione, aminopyralid, picloram, triclopyr and fosamine their agriculturally acceptable salts and their agriculturally acceptable salts and its agriculturally acceptable derivatives.
