The use of the fungus Ascochyta caulina as a biological control agent for the weed Chenopodium album. Evaluation of the bioherbicide formulation efficacy of Ascochyta caulina on different life stages of the weed plant Chenopodium album under laboratory and field conditions comparing Libyan and UK populations.
Chenopodium album is considered one of the most important weeds adversely affecting agricultural production due to its highly competitive influence on field crops. Chemical herbicides have increased the efficiency of farming, but recently problems of herbicideresistant weed populations and …
