English: The poster includes four large columns and 16 colors. Large columns are separated by thick white lines. The first left large column contains: 1) photosystem ΙΙ inhibitors, 2) photosystem Ι inhibitors , 3) PPG oxidase or protox inhibitors, and 4) carotenoid biosynthesis inhibitors; the second left large column contains: 1) ALS or AHAS inhibitors, 2) EPSP synthase inhibitors, 3) glutamine synthetase inhibitors, and 4) unknown; the third left large column contains: 1) mitosis inhibitors, 2) fatty acid and lipid biosynthesis inhibitors, 3) ACCase inhibitors, 4) dihydropteroate synthetase inhibitors, and 5) oxidative phosphorylation uncouplers; and the fourth left large column contains: 1) mitosis inhibitors, 2) cellulose inhibitors, 3) synthetic auxins, and 4) auxin transport inhibitors. The large columns and colors are made to simplify the herbicide classification. For example, the first left large column and the upper three colors of the second and third left large columns are affected by the processes of photosynthesis, amino acid and fatty acid biosynthesis, respectively. Active ingredients of the herbicides based on their chemical structure have been classified within chemical families. Herbicide groups on the upper left and right side of the chemical family are specified by the HRAC and WSSA groups and their active ingredients have been placed under the structure of the chemical family, thus each cell contains the name and structure of chemical family, herbicide group, and active ingredient. Each cell is separated by thin white lines from the other cells on the image. Overall, the poster includes 430 herbicides which have been classified by 16 mechanisms of action and 119 chemical families. 23 HRAC groups and 28 WSSA groups have been designated for the herbicides.
