Evaluating the mycoherbicide potential of a leaf-spot pathogen against Japanese knotweed
Japanese knotweed is a highly invasive weed that impacts severely on native biodiversity and local infrastructure in its introduced range. Whilst chemicals are currently used to control the weed, this approach is costly and unsustainable. Biological control is an alternative method. The damaging leaf-spot fungus, Mycosphaerella polygoni-cuspidati, which attacks the plant in its native range was found not to be suitable as a classical biocontrol agent. However, the pathogen is considered to hold potential as a mycoherbicide. The aim of this project is to undertake proof-of-concept research into a potential mycoherbicide, in collaboration with the private industry.
BioSpace: Using space-enabled remote sensing for long term sustainable growth of biopesticide use
Pests and diseases cause significant losses of crops around the world and are a significant threat to food security. In China and Laos, locusts affect over two million hectares of agricultural land and recently, the fall armyworm is becoming prevalent in China and Southeast Asia, already affecting 35,000 hectares of maize in Laos. Due to a lack of detailed information on where risks to crops are greatest and farmers using inappropriate and ineffective control measures, managing the damage from pests can be problematic.
Piloting biopesticide use to manage fall armyworm in South Sudan
Crop protection in Africa relies heavily on the use of synthetic chemical pesticides. They are perceived to be more effective than other methods but human health concerns and the resistance to them in pest populations is shifting the tide towards lower risk pest management methodologies. Biopesticides are considered a suitable alternative in fall armyworm (FAW) management as they are typically more specific than most synthetic pesticides and are a lower risk to health and the environment. However, those commercial biopesticide products that are available, from the Americas and Europe, to use against FAW in Africa are not available due to inadequate knowledge on their efficacy.
