“…However, it is the bulbs and rhizomes that are traded and these are often difficult to identify (J€ ager & Stafford, 2012). and the reliance on wild harvesting, threatens to affect their abundance and possibly make them susceptible to extinction (Aremu & van Staden, 2013). Dold & Cocks (2002) estimated that an average healer in the Eastern Cape Province of South Africa trades 92.5 kg of T. alliacea material per annum at an estimated R83.50 (7.8 USD) per kg.…”

Arthropod pests can cause substantial damage to the maize plant resulting to yield losses of up to 100%. Rural farmers often do not afford the costs of chemical insecticides; alternatively they tend to use indigenous pest control methods which include the use of plants. An ethnobotanical survey of plants used in the Eastern Cape by farmers to control field pests of maize was conducted in 14 different towns under 5 district municipalities from 217 rural small-scale farmers. Data were analysed using descriptive statistical methods. Findings revealed that some of the farmers were knowledgeable of indigenous pest control methods to manage pests of maize and as a result they applied them. This information was found to reside with few elderly people of which majority were females. Although, most of the plants cited were from families Solanaceae and Asteraceae, the most preferred was Chenopodium ambrosioides, a perennial herb from the family Chenopodiceae. The largest percentage of plants used was mainly those harvested from the wild and were mostly herbs. In making formulations, respondents commonly used leaves and most of the preparations were applied on the whole plant using different modes of application. It may be possible that not all the plants mentioned by participants can control target pests. These findings, however, raise a need for a continuous validation and documentation of indigenous pest control methods thus bridging the generational gap. Further research on these methods may play a significant role in reducing costs associated with insect pest control in crop production.

“…Uses include the treatment of fits, fevers, rheumatism, paralysis, headaches, high blood pressure, heart problems, chest complaints, stomach ailments, and constipation/colic. The plants are also extensively used to treat various microbial infections, including oral and ear infections or pulmonary tuberculosis (Lyantagaye, 2011;Aremu and Van Staden, 2013).…”

a b s t r a c t Edited by J Van StadenKeywords: Tulbaghia violacea Alliaceae Society garlic Marasmicin Allicin Antimicrobial activity Tulbaghia violacea Harv. (Alliaceae) is a perennial plant native to South Africa. Various preparations made of this plant are extensively used for the treatment of microbial infections. It was shown that the key antimicrobial compound of T. violacea is the thiosulfinate marasmicin (2,4,5,7-tetrathiaoctane-4-oxide) enzymatically formed upon tissue disruption. Antimicrobial activity of marasmicin was evaluated (MIC 4-64 μg/ml) and compared with that of allicin (MIC 4-32 μg/ml), the prominent bioactive compound of garlic (Allium sativum). An HPLC method was developed and used for quantification of marasmicin in various Tulbaghia preparations. It was found that the content of marasmicin can be dramatically affected by storage conditions and subsequent treatment of the plant material. To achieve significant antimicrobial effects, it is essential to avoid exposing the plant to elevated temperatures (e.g., during drying). To maximize marasmicin formation, it is advisable to use freshly gathered plants and homogenize them in water as finely as possible. Extracts of T. violacea should be kept at low temperatures to retain their antimicrobial activity.
