Why it matters Fall armyworm (Spodoptera frugiperda) is a major biosecurity threat to maize production in South Africa. With no natural containment and limited local data on its seasonal patterns, this pest has rapidly spread across key maize-producing regions, causing significant yield losses. This project focuses on understanding when and where fall armyworm populations peak,

Why It Matters? Climate change is reshaping pest dynamics in agriculture, threatening food security and smallholder livelihoods. In South Africa’s Limpopo Province, farmers growing maize and sorghum are particularly vulnerable to stem borers such as the maize stalk borer (Busseola fusca), pink stem borer (Sesamia calamistis), and spotted stem borer (Chilo partellus). These pests can

Why it matters Maize ear rots not only reduce grain quality and yield but also pose serious food safety risks due to the production of harmful mycotoxins. These fungal diseases are difficult to control, especially in wet seasons like those recently experienced in South Africa. To help producers protect their crops and consumers, this project

Why It Matters Sclerotinia sclerotiorum is a destructive fungal pathogen affecting a wide range of crops in South Africa. The South African Sclerotinia Research Network (SASRN) was established to foster collaboration among researchers, industry stakeholders, and government to address this challenge. Initially aimed at supporting early-career researchers, the network has grown into a national platform

Why It Matters Sclerotinia sclerotiorum is a devastating fungal pathogen affecting oilseed crops, particularly sunflowers. Its resilience stems from melanin-coated sclerotia, which protect the fungus from environmental stress and microbial degradation. These structures persist in soil for years, increasing disease risk and reducing field profitability. This project explores a novel polymer-based intervention using pyrones and
