| Leaves repel rose spider mites | |
| Work at Writtle College, UK, suggests that using the common African cabbage plant, Cleome gynandra (Capparaceae) as a companion plant in cultivation or to obtain leaf extract for application as a foliar spray, a notable deterant factor can be obtained against sider mites. The Writtle experiments demonstrate that that rose spider mites avoid the leaves of C. gynandra and move away from them. The incorportaion of C.gynandra leaves or the application of foliar spray extracts could enhance the efficiciency of bio-control agents in IPM programs. Further trials and experimentation is indicated in various crops in protected and cultivation and in outdoor production beds. “FlowerTech” 2005, Vol 8, No5. www.Hortiworld.nl Writtle College: Fax 0044 1245 420456, E-mail: info@writtle.ac.uk, www.writtle.ac.uk C. gynandra is an erect, annual herb that grows to a height of 25-60cm. The leaf and flower stalk, leaves and stems are covered with glandular hairs. Ther species is probably a native of Africa and widely distributed in tropical and subtropical regions of the world. Fresh leaves are cooked and eaten as spinach or dried and stored for later use as a relish with porridge.English |
