Aims: To determine effect of selected plant concentrates on the growth of field dodder (Cuscuta
campestris).
Study Design: A factorial experimental design; using four level extract application from blue gum,
cypress, napier grass and distilled water as the control.
Place and Duration of Study: Masinde Muliro University of Science and Technology from June
2018 to March 2019.
Methodology: It incorporated use of 4 by 4 contingent field experiment, with Duranta erecta and
Cuscuta campestris as independent and dependent variables respectively. It contained three
experimental groups of extracts from the blue gum, cypress, Napier grass and distilled water as a
control. Each treatment level was replicated four times. Samples of the affected plants (Duranta
erecta) intertwined with parasite were purposive randomly selected. The parasites point of
attachment through a haustoria for selected plants was marked with threads as a start point of

measurements taken. Marked strings were of different colors to distinguish the type’s treatments
(concentrates) being applied. Application of 30 ml/cm2 each of the extracts was done on both plant
and parasite. Measurements of the plant heights, parasite length, number of plant leaves and
application of extracts were done after every 48 hours.
Results: Analysis of the effects of different concentrates as treatments of the same on parasite
length increase, exhibited some differences (F = 1.648, P = .18). The mean ranged from lowest to
highest extracts of the; cypress at (29.0 ± 17.23), Napier grass at (34.6 ± 28.7), blue gum at (38.7 ±
28.6), and distilled water at (39.4 ± 27.4) respectively.
Conclusion: Cypress extract had the most effect on the C. campestris. Followed by blue gum
extract which exhibited some effects, then Napier grass. This evidently shows that the parasitic
weed can be controlled biologically.
