Detecting resistant to action of herbicides — inhibitors of acetolactatsynthase of weeds

Abstract

Purpose. Detection of potentially resistant herbicides - acetolacetate synthase inhibitors (ALS) of weed biotypes on the crops of leading agrarian companies of Ukraine and determination of methods for counteracting the emergence of resistant biotypes of weeds. Methods. Selection of seeds of control and potentially resistant species of weeds in field conditions. Detection of resistance in laboratory research. Statistical analysis. Results Resistance to the action of herbicides - ALS inhibitors of weeds (canal of Theophrastus and white loboda) has been found, which determines the need for information preparation for farmers, the immediate change of "reduced" crop rotation, and also the application of herbicides with another mechanism of action. For grain cereal problems, the presence of resistant crop weeds should be periodically treated with phenoxyacetic, benzoic or piconic acid derivatives (esteron, banvel, clopyralide, etc.) or mitotic cycle inhibitors and photosynthesis (for example, to introduce a marathon herbicide in the autumn). Conclusions For the first time in Ukraine, resistance to the action of herbicides - ALS inhibitors is identified by biotypes of theophylline rope weeds in white loboda. This determines the need for extensive studies of the presence of herbicide-resistant and other types of weeds resistant to the action, in appropriate informational support for farmers and the immediate implementation of measures to prevent the emergence and spread of weeds resistant to herbicides.
