Studies on biological control of Chenopodium album by Ascochyta caulina

Research output: Thesisexternal PhD, WU


<p>Studies were carried out to assess the perspectives of the plant pathogenic fungus <em>Ascochyta caulina</em> (P. <em></em> Karst) v.d. Aa & v. Kest. as a mycoherbicide against <em>Chenopodium album</em> L., world-wide a weed in arable crops. <em>A. caulina is</em> associated with necrosis of leaves and stems of plants belonging to genera of <em>Chenopodium</em> L. <em></em> and <em>Atriplex</em> L. The studies were focused on recognition of factors that may limit disease development and on relationships between disease development and control. Three control strategies of <em>C.</em><em>album</em> were studied: application of <em>A. caulina</em> to the soil, to young plants and to flowering plants. Disease development of plants after the application of the fungus was quantified for a broad range of conditions. Relationships between disease development and control were demonstrated. The perspectives of <em>A.</em><em>caulina</em> as a mycoherbicide against <em>C.</em><em>album</em> were discussed. It was concluded that the fungus has a good potential to be further developed into a mycoherbicide against the weed.
