Characterisation of Phomopsis spp. associated with die-back of rooibos (Aspalathus linearis) in South Africa
Die-back of rooibos (Aspalathus linearis) causes substantial losses in commercial Aspalathus plantations in South Africa. In the past, the disease has been attributed to Phomopsis phaseoli (teleomorph: Diaporthe phaseolorum). Isolates obtained from diseased plants, however, were highly variable with regard to morphology and pathogenicity. The aim of the present study was thus to identify the Ph...
متن کاملUse of Plant Pathogens as Bioherbicides to Manage Weeds in Horticultural Crops
Certain fungal, bacterial, and viral pathogens can be mass-produced and used as biological herbicides to control weeds in crops. This approach, referred to as the “bioherbicide” or the “inundative” biological control strategy, is based on our ability to manipulate certain weed-pathogen systems to cause highly damaging levels of disease epidemics during critical periods of weed interference and ...
متن کاملEVects of diVerent Beauveria bassiana isolates on Weld populations of Lygus lineolaris in pigweed (Amaranthus spp.)

Lygus spp. populations often build on alternate host plants before moving to cotton, and in the midsouthern U.S. wild host plants, such as pigweed (Amaranthus spp.), play a major role in L. lineolaris population development. Three isolates of the entomo...
متن کاملInteraction Effect of Arbuscular Mycorrhiza and Redroot Pigweed (Amaranthus retroflexus L.) on Growth and Yield of Sunflower under Water Stress Conditions
The management of soil elements by biological fertilizers is considered as an important attribute of sustainable agriculture. In order to evaluate the interaction effects of Arbuscular mycorrhizal fungi and redroot pigweed (Amaranthus retroflexus L.) on growth and yield of sunflower (Helianthus annuus L.) under water stress conditions, a field study was conducted in 2015 at School of Agricultur...
متن کاملHaemonchus spp. in sheep farmed under resource-poor conditions in South Africa--effect on haematocrit, conjunctival mucous membrane colour and body condition.
A longitudinal study was conducted on the differential faecal egg counts, haematocrits and body condition scores of sheep belonging to resource-poor farmers at Rust de Winter, Gauteng province, and Kraaipan, North West Province, South Africa. The animals were scored for level of anaemia using the FAMACHA method, an assay for the clinical evaluation of anaemia caused by Haemonchus spp. Periods o...
