Economic control of cynodon: A theoretical strategy for emerging sugarcane farmers † [Full subscriber]

This paper focuses on the economics of reclaiming weed-infested sugarcane and offers a step-wise strategy to increase the area of well-managed sugarcane for emerging farmers. It uses a worst-case weed infestation scenario, where fields have been infested with Cynodon dactylon (L.) Pers. (cynodon). Information on input costs and returns calculated from several trials have been used to show that, although a slow process, progress with cynodon control and subsequent yield improvements can be made. Emerging growers often cannot afford to replant a full hectare in one season; two replanting strategies are therefore proposed. Firstly, by scaling down operations so that…
