Abstract

The pineapple (Ananas comosus L. Merri) is a species belonging to the genus Ananas the Bromeliaceae Family and its consumption is appreciated in many countries. Phytosanitary problems are still present in the world pineapple, limiting the development of crops, causing losses of up to 100 % of production and damages in post -harvest. A major problem is the Fusarium wilt (Fusarium guttiforme) that causes major economic losses. This study aimed to evaluate alternative methods for the management of Fusarium in pineapple. The treatments were herbal extracts of ironwood ( Caesalpinia ferrea) , mimosa (Anadenanthera colubrina); melon São Caetano ( Momordica charantia) used in concentrations of 500 , 1000, 1500 and 2000 ppm; inducer acibenzolar -S-methyl resistor (2.0g / ha); fungicide Thiabendazole (75ml / ha); combination of two applications of the plant extract melon -São Caetano - and two fungicide applications and the control (distilled water). Peaches were sprayed from the beginning of flowering, following the schedule of conventional spraying with fungicide commonly used by the farmer, was conducted in a commercial orchard in the rural municipality of Pombos - PE. The herbal extract of M. charantia the 1000, 2000 ppm and combination herbal extract + fungicide reduced the severity of fusarium. M. charantia extract improved post-harvest fruit quality of pineapple.
