CLP concludes 5th Herbicide Mode of Action and Herbicide Resistance Management webinar
CropLife Philippines recently held the fifth session of the Herbicide Mode of Action and Herbicide Resistance Management webinar focused on Herbicide Groups including ACCase inhibition, ALS inhibition, EPSP synthase inhibition, PPO inhibition, and VLCFA inhibition.
The webinar was conducted by Professor Nilda Roma-Burgos CSES, of the University of Arkansas.
During her talk, Dr. Burgos explained the technicalities and the factors that affect the different inhibitions and how they impact the effectiveness of herbicides on crops.
She also discussed the characteristics of these inhibitors and their patterns to familiarize the participants with their technical and practical aspects.
After discussing the various aspects of these mechanisms, Dr. Burgos shared the best methods for reducing the risk of resistance evolution.
According to her, the first step is reviewing the field history and starting with clean fields which will reduce the weed population size.
Dr. Burgos said that farmers also need to prevent new weed seed deposits and diversify the crops that they use in their fields by planting competitive varieties and optimizing crop utilization and crop health.
She reiterated the best practices mentioned in previous webinars on diversifying herbicide mode of action with mixtures and sequences.
Also among her recommendations were an overlap of residual herbicides, ensuring that clean seeds are planted, monitoring and testing for resistance, and the implementation of mitigation measures.
The webinar was well received by the participants.
