There is less danger of over-bearing with consequent die-back, the incidence of insects pests such as Thrips and White Stem-borer (Anthores leuconotus) is usually less and weeding costs are generally far lower in shaded coffee especially if weeds such as Couch (Digitatia scalarum) or water-Grass (Cyperus rotundus) are present in the area.enhttp://creativecommons.org/licenses/by-nc/3.0/Journal ContributionAcaciaShadeTreesCoffeehttps://doi.org/10.1080/03670074.1954.11664923
