- Abstract:
- ... Macadamia nuts are known globally for their high quality and economic value. Global macadamia commercial nut production amounts to 60,000 metric tonnes and is increasing steadily. South Africa is the leading producer with 29% of worldwide kernel production. Commercial macadamia germplasm was originally selected from a small genepool (mainly Macadamia integrifolia species) from a limited geographic ...

- Abstract:
- ... Syzygium cordatum (Myrtacease) is one of the most common encountered and widely distributed tree species indigenous to South Africa. This tree is often affected by a malformation disease characterized by grossly misshapen inflorescences that do not bear fruit. Because such symptoms have previously been attributed to Fusarium species in other plants, the aim of this study was to determine the diver ...

- Abstract:
- ... The two-spotted stink bug, Bathycoelia distincta Distant (Hemiptera: Pentatomidae), is a serious pest in South African macadamia orchards. This pest is predominantly controlled using insecticides, thus alternative control methods are essential. The stink bugs arrive as adults in the orchards, during the early nut set season, but little is known about their alternative plant hosts before their arri ...

- Abstract:
- ... Fusarium circinatum is a pathogen causing serious post-planting mortality of Pinus patula seedlings in southern Africa. Containerised planting stock that is asymptomatic but associated with F. circinatum in the nursery is thought to be the cause of this problem. The aim of this study was to determine if re-use of seedling containers could be a source of inoculum resulting in asymptomatic planting ...

- Abstract:
- ... The pitch canker pathogen, Fusarium circinatum , has major impacts on production in pine nurseries and plantations in South Africa. Thus far, efforts to reduce local spread have focused on rouging of infected pines and sanitation to eliminate local sources of inoculum. Although the host range of F. circinatum was thought to be limited to pines and Douglas-fir, recent studies in California indicate ...

- Abstract:
- ... The primary symptoms associated with Fusarium circinatum infection in pine seedling nurseries are root and collar rot, shoot and tip die-back and seedling mortality. Management of this pathogen in nurseries usually involves the integration of various strategies relating to sanitation, insect control and fungicide treatment. The overall goal of this study was to use quantitative real-time PCR (qPCR ...

- Abstract:
- ... Fusarium circinatum Nirenberg & O’Donnel is listed among the species recommended for regulation as quarantine pests in Europe. Over 60 Pinus species are susceptible to the pathogen and it also causes disease on Douglas-fir (Pseudotsuga menziesii (Mirb.) Franco) and species in genera such as Picea and Larix. The European Food Safety Authority considers the probability of new introductions ...

- Abstract:
- ... Fusarium circinatum is an important fungal pathogen of Pinus species. In South Africa, it is the most significant pathogen of Pinus patula seedlings in forestry nurseries where it presents a substantial constraint to productivity and can continue to cause mortality in-field for up to two years after establishment. This study describes the results from two trials where P. patula seedlings were inoc ...

- Abstract:
- ... Scientific communication is facilitated by a data-driven, scientifically sound taxonomy that considers the end-user’s needs and established successful practice. In 2013, the Fusarium community voiced near unanimous support for a concept of Fusarium that represented a clade comprising all agriculturally and clinically important Fusarium species, including the F. solani species complex (FSSC). Subse ...
