Source of funding- Ruforum to the tune of US$59,996. (Team, Prof Ogweno J. O and Dr Nyaanga G. J). The studies identified the potential of Leonotis nepetifolia L. and Ocimum gratissimum L (Lions ear and African Basil) extracts in the management of Tetranychus urticae Koch (Acari: Tetranychidae (Adult two spotted spider mites) and Ascochyta blight disease on French beans, under small holder production in Kenya:

Source of funding –Egerton University, total amount Kshs 400,000. (Team members Prof Ogweno J O and Prof Mulwa RSM). We have collected and morphologically characterized 37 landraces of Cleome gynandra from most parts of the country. Currently we are in the process of developing a variety through single seed/pod descent.
  3. 2011-2013 Enhancing Production, Value addition and Marketing of Indigenous vegetables (Cowpeas, Spider plant, nightshades, amaranth, pumpkins) French beans and mushroom among small holders farmers in Kenya. (Pumkins component). Source of Funding KAPAP, total amount Kshs 3,337,326.
