She said: The fight against weeds in wheat fields in the northern half of the country, such as East Azerbaijan, West Azerbaijan, as well as Khorasan Razavi and Fars provinces, and in Sardsir provinces, continues for another 20 days.
Ahangaran emphasized timely fight against weeds and asked the farmers to use recommended herbicides based on the condition of dominant weed flora in the fields, and in consultation with plant protection experts.
She pointed to the emergence of resistance in weeds and stated: Successive use of the same type of herbicide by farmers in several years causes resistance in weeds and may not be effective in controlling weeds in the fields in the future due to the development of resistance.
