Factors That Enable The Reduction Of The Rate Of Herbicides Inhibitors Of Als Enzyme: A Literature Review

The purpose of this review was to organize the data available on the literature regarding environmental and physiological factors that affect the efficacy of ALS inhibitors. Among environmental factors that affect the ALS inhibitors action are: temperature, relative humidity, irradiance and plant nutritional status. Among physiological factors that affect the herbicide dose are the enzymes involved on the detoxification of the herbicides and those enzymes involved on alleviating the oxidative stress due to herbicide action. Further integration knowledge studies are required in order to develop strategies to optimize the activity of ALS inhibitors allowing the reduction of herbicide dose without compromising the efficacy of weed control, and therefore ensure optimum crop yields.
