The objectives were to evaluate plant extracts and the concentration that reduces the incidence of damage by Carmenta foraseminis in Theobroma cacao, to determine botanical characteristics of Artemisia absinthium, Ocimum basilicum, Zingiber officinale, and Dysphania ambrosioides, to evaluate crop damage and to obtain the optimum concentration of extracts. Treatments were established as following: Artemisia absinthium (T1), Ocimum basilicum (T2), Zingiber officinale (T3) and Dysphania ambrosioides (T4), all were applied in 06 opportunities at concentrations of 25, 50 and 75%. The botanical characteristics of Artemisia absinthium are: perennial herb up to 1m high, covered with fine hairs, branched and erect stem, alternate leaves, 5-7 cm long, divided into triangular segments with narrow subdivisions; Ocimum basilicu: herbaceous, annual, erect and branched stems, leafy, 30-50 cm high, leaves 2-5 cm, smooth, oblong, opposite, petiolate and slightly toothed (Marrero et al., 2004); Zingiber officinale: height between 50-100 cm, pale green coloration, spicy root flavor by resins and aromatic oils (M, 2007); Dysphania ambrosioides: herbaceous, 50-60 cm tall, alternate leaves, ovoid and lanceolate, serrated edges, 5-8 cm long and 1-3 cm wide, short petiole, light green (Mejia and Rengifo, 2000). The plant extracts of Ocimum basilicum, Dysphania ambrosioides, Artemisia absinthium and Zingiber officinale did not show favorable results in damage control at a concentration of 25%; at concentrations of 50 and 75% they showed higher incidence. There is statistical evidence that the plant extract of Zingiber officinale showed better results in the 04 blocks, of which the best result was obtained in BII.
