Athlete (Mesosulfuron + Iodo sulfuron + Mefenpyr diethyl 1.2% OD)

It is a selective, systemic post-emergence herbicide, absorbed by foliage and roots. It belongs to the class of sulfonylurea herbicides and inhibition of aceto-lactase synthase (ALS) or Acetohydroxyacid synthase (AHAS) mode of action. Its mode of action is by branched chain amino acid valine, leucine, and isoleucine synthesis inhibition.

It is a selective, pre-emergence dinitroaniline herbicide which is mainly absorbed through the coleoptile and hypocotyl of weeds and prevents the germination of the weed seed through cell division blockage in the hypocotyl, as well as the development of the root system. It is not transferable in plants. Increasing the diameter of the root, causing swelling in the meristem area of the root tip, preventing the production of lateral roots are the symptoms of using this herbicide.

It is a selective, contact herbicide. It belongs to the class of N-Phenyl-oxadiazolones herbicides and inhibitor of protoporphyrinogen oxidase (PPO). The development of the shoots is stopped as soon as they emerge - their tissues decay very rapidly.

It is a non-selective, connected, and semi-systemic phosphonic acid herbicide inhibition of glutamine synthesis, leading to a complete breakdown of ammonia metabolism and subsequent accumulation of ammonia in tissues. This herbicide also interferes with photosynthesis. Glufosinate ammonium is used to control annual and non-perennial weeds, so this herbicide does not control perennial weeds well. Chlorosis, withering of tissues and finally, the death of the weed within 1 to 2 weeks are the symptoms of the effect of the herbicide.
