Method of selectively controlling morning glory (Ipomoea) spp
View Patent ↗A method of selectively controlling morning glory spp., by treating a lower portion of a hill of morning glory spp. with one compound or a combination of two or more compounds selected from glufosinate, L-glufosinate, bialaphos, paraquat, diquat and agriculturally acceptable salts of the compounds.
1. A method of selectively controlling morning glory spp. comprising treating a lower portion of a hill rather than the entire hill of morning glory spp. with one or more herbicidal compounds selected from a group consisting of glufosinate, L-glufosinate, bialaphos, paraquat, diquat and agriculturally acceptable salts of the compounds.
2. The method as claimed in claim 1 , wherein the herbicidal compound is glufosinate or L-glufosinate or an agriculturally acceptable salt of glufosinate or of L-glufosinate.
3. The method as claimed in claim 1 , wherein the selective control is performed in a crop.
4. The method as claimed in claim 3 , wherein the crop is a soybean cultivation, fruit cultivation or cotton cultivation.
5. The method as claimed in claim 1 , wherein the herbicidal compound or herbicidal compound combination is applied at an application rate of 0.05 to 2.0 kg/ha.
6. The method as claimed in claim 3 , wherein the herbicidal compound or herbicidal compound combination is applied by spraying devices which direct the spray drizzle to the portion of morning glory below the level of the leaves of the crop plants and between the crop plants.
7. The method as claimed in claim 6 , wherein the crop plant is soybean.
8. The method as claimed in claim 6 , wherein the herbicidal compound or the herbicidal compound combination is applied at an application rate of 0.05 to 2.0 kg/ha.
9. The method as claimed in claim 8 , wherein the herbicidal compound is glufosinate or L-glufosinate or an agriculturally acceptable salt of glufosinate or L-glufosinate.
10. The method as claimed in claim 6 , wherein the herbicidal compound is selected from the group consisting of paraquat, diquat and agriculturally acceptable salts thereof.
11. The method as claimed in claim 10 , wherein the herbicidal compound combination is paraquat dichloride and diquat dibromide.
12. The method as claimed in claim 6 , wherein the herbicidal compound is selected from the group consisting of bialaphos and agriculturally acceptable salts thereof.
13. The method as claimed in claim 12 , wherein the herbicidal compound is bialaphos sodium.
