Abstract : This paper studies the impact on phenology, epidemiology and subsequently on production of articifial defoliation for the control of Colletotrichum leaf fall of Hevea brasiliensis for the susceptible rubber tree clone GT 1. Large-scale observations of tree phenology over 4 years show the impact of the treatment on foliage behaviour. These results provide on understanding how the trees escape from the disease and how the occurence of the an epidemic is prevented. A 50% increase in foliage density led to around a 40% increase in yields on the susceptible clone GT 1.
