QUANTIFICATION OF DAMAGE AND YIELD LOSSES AND MANAGEMENT OF ROOT-KNOT NEMATODES IN CONILON COFFEE

ABSTRACT Commercial exploitation of the coffee crop is one most important activities in world’s agricultural sector. One main phytosanitary problems affecting presence Meloidogyne incognita. Several measures have been tested for management this pathogen, albeit with low efficiency. The objective work was to quantify damage and losses manage M. incognita race 1 Pochonia chlamydosporia Trichoderma harzianum biological nematicides, comparing them a chemical nematicide. experiment carried out commercial area naturally infested by nematode cultivated conilon variety ‘Vitória INCAPER 8142’, clone V02. treatments were Carbofuran nematicide nematicides composed P.
