In-field detection of S. sclerotiorum ascospores in soybean
One of the major challenges in managing diseases caused by Sclerotinia sclerotiorum is that much of the infection risk begins before symptoms are visible. The pathogen produces microscopic airborne spores, called ascospores, which are...
Tillage and Sclerotinia in oilseed crops: solution or setback?
For decades, the effectiveness of tillage systems in managing diseases caused by Sclerotinia sclerotiorum has remained a subject of debate among researchers and producers alike. Central to this debate is the position of sclerotia...
ONKRUIDBEHEER in ’n moontlike droogtejaar
Produsente is in ’n bevoorregte posisie om bogemiddelde oordragvog te hê vir die komende seisoen. Vog moet egter reg bestuur word om die moontlike El Niño se impak op somergewasse so laag as moontlik...
A practical guide to weed identification
Weeds grow in the wrong place at the wrong time, competing with crops for water, nutrients, and light, thereby reducing crop yield and quality. Effective weed control remains a major challenge due to the...
Die rol van oppervlak- aktiewe molekules in skuimgenerering en fase-oordrag
Toediening van landbouprodukte word gereeld belemmer en vertraag deur hardnekkige skuim wat in spuittoerusting voorkom. Skuim verhoog die hoeveelheid lugborrels in die mengsel en kan lei tot spuitkarre wat oorstroom. Dit kan selfs veroorsaak...
Diagnostic tools for detecting Goss’s wilt: from field symptoms to lab confirmation
Maize producers are faced with an increasing number of disease threats that significantly reduce yield and grain quality, leading to an impact on trade. The early identification of diseases is therefore an essential step...
The importance of IPM in managing insect pests
Insects possess a remarkable ability to adapt to a changing environment. They have fast life cycles and can spread fast and effectively to new areas. Because of these abilities insect populations can rapidly become...
Grain aphid surveys show loss of susceptibility against some active ingredients
Given the adaptive ability and high damage potential of aphids, it is necessary to monitor aphid populations in wheat production areas and screen them for shifts in sensitivity against commonly used active ingredients. Grain...
Geïntegreerde siektebeskerming bied ’n volhoubare benadering
Graangewasse soos mielies, sojabone, sorghum en sonneblom vorm die ruggraat van voedselproduksie en landbou-ekonomieë wêreldwyd. Hierdie gewasse word egter voortdurend bedreig deur ’n verskeidenheid siektes wat deur swamme, bakterieë en virusse veroorsaak word. Siektes...
Graanroosluis veral gevaarlik saam met GGDV
Groot getalle graanroosluis (Metopolophium dirhodum) (Figuur 1 A-F) het in 2024 en 2025 in die Wes-Kaap se koring- en garsproduk-
siestreke voorgekom. Hierdie luisspesie voed primêr op die onderkant van die oudste blare van koring-...
