A comparison of weed control programmes in coffee

Abstract

A previous article in Harvest (Vol. 1, No. 3) described two weed control trials in coffee at Aiyura. They were in coffee which was heavily infested initially with perennial grasses and this resulted in all treatments being relatively expensive. The trial described here was on a plantation with a more normal weed population, and the costs quoted are more directly comparable with most other highlands coffee areas. One of the treatments compared in this trial is based on the soil-applied herbicide simazine. A recent large price drop has brought this herbicide into consideration for use in coffee so its performance in this trial is of interest.
