摘要: Meloidogyne exigua is a plant-parasitic nematode that causes great losses to coffee farmers. Thus, contribute the development of new products control this parasite, present work studied effect volatile organic compounds (VOC) on and plants (Coffea arabica), since these are known be used in plant defense against other agronomical pests. The number galls M. was reduced when aerial part sprayed with combinations methyl jasmonate + jasmone, (Z)-hex-3-en-1-ol (E)-hex-3-en-1-ol (Z)-hex-2-en-1-ol (E)-hex-2-enal, (E)-hex-2-enyl acetate hexyl acetate, meso-butane-2,3-diol butane-1,2-diol butane-1,3-diol butane-1,4-diol, 3-hydroxybutan-2-one 4-hydroxybutan-2-one or linalyl nerolidol. These VOC also caused alterations concentrations substances such as alkaloids, phenols, amino acids carbohydrates, roots plants. findings suggest may explored potential for
