Cost-effective weed management in plantation crops in Mindanao [Philippines]
1988
Pamplona, P.P. | Tinapay, S.S.
A survey of different weed control practices and cost-effective measures was carried out in various plantation crops in Mindanao [Philippines]. The crops surveyed include banana (Musa spp.), cacao (Theobroma cacao L.), coffee (Coffea spp.), oil palm (Elaeis guineensis Jacq.), rubber (Hevea brasiliensis Muell. Arg.), and pineapple (Ananas comosus). In all plantations, weeds are serious problems during the immature stage of the crop. The problem becomes less when the crops mature or as the canopy of the crops close-in, thereby decreasing the germination and growth of weeds. Most plantations rely on mechanical cultivation to prepare the field and establish the crops ahead of the weeds. As soon as the crops are established in the field, the common weed control practices include the application of herbicides and supplemented by mechanical cultivation and/or slashing between the rows and clean or ring weeding in the rows. The cost of weed control during the immature stage of crop varied from P2,500/ha per year in banana and rubber and P2,800 in cacao and coffee particularly for practices dependent on herbicides. Among the common herbicides are: paraquat, glyphosate, diuron, glufosinate-ammonium and bromacil. Reduction in the cost of weeding is generally carried out by using herbicide rotation or a combination of herbicides and/or mechanical cultivation.
