| Organic agriculture can and should play an important role in solving future challenges in producing food. The low level of external inputs combined with knowledge on sustainablity minimizes environmental contamination and can help to produce more food for more people without negatively impacting our environment. Organic agriculture not only includes farming as a production practice but it also includes processing, trade and consumption. Nevertheless, Organic agriculture must always evolve to overcome emerging challenges. Science-based knowledge attained through dedicated research is required to strengthen organic food and farming as a means to solve future challenges. In 2010, a global discussion about Organic 3.0 was initiated to address current problems... |

| The potential of ethanolic extracts of some common medicinal plants of Ethiopia for control of late blight (Phytophthora infestans) in tomatoes and potatoes has been investigated in vitro and in vivo. The application of several ethanolic plant extracts resulted in a significant inhibition of mycelium growth (0.25% m/v) and an impairment of late blight disease severity in vivo (1% m/v). Extracts from Hagenia abyssinica, Lepidium sativum and Lippia adoensis showed the strongest suppression of mycelium growth. The application of extracts derived from the H. abyssinica gave the highest in vivo bioactivity against P. infestans on tomatoes, but no effect was noted in potatoes under field conditions. The general potential of these extracts for late blight control... |
