Tno  in 1-  the state of Rio Grande do Sul it is possible to produce pineapples with TSS higher than the legal minimum (12°Brix) and equal quality to that produced in tropical regions. Between weeding, diuron or atrazine+simazine, choose that with lower economic and environmental costs and avoid the use of glyphosate.
