Weed control in the pineapple crop

Abstract

A study carried out at the National Research Center for Cassava and Fruits - CNPMF/EMBRAPA - at Cruz das Almas, Bahia, Brazil, in a randomized design with eight replications, to study weed control in pineapple (‘Pérola') crop in order to reduce the production costs, since labor force is a serious problem in many of Brazilian pineapple areas. Production data did not show significant difference among treatments, but an economic analysis indicated that the chemical weed control was better than the mechanic and physical methods, the same as the traditional hoe weeding and the plastic mulch in the double rows associated either with hoe weeding or weedicide between the rows.
