The off-season period for açaí palm production cause social and economic problems that affect producers and consumers. Two species are used for açaí pulp production, Euterpe oleracea and E. precatoria. These species have some distinct characteristics, including the harvest period. The cultivation of açaí palm is expanding in the metropolitan region of Manaus, state of Amazonas, AM, and there are no studies on the harvest period of these species under cultivated conditions in this region. The objective of this study was to evaluate the reproductive phenophases of the açaí palm E. oleracea and E. precatoria grown in the metropolitan region of Manaus, state of Amazonas and to check the harvest period of these species in this region. O período de entressafra da produção de frutos de açaí traz problemas de ordem social e econômica que afetam produtores e consumidores. Duas espécies são utilizadas para produção da polpa do açaí, Euterpe oleracea e E. precatoria. Essas espécies apresentam algumas características distintas, incluindo o período de safra. Não existem estudos, com relação a essas espécies, sobre o período de safra do açaizeiro na região metropolitana de Manaus, AM, onde a cultura está em expansão. Assim, objetivou-se com esse trabalho estudar a distribuição mensal da produção de frutos dos açaizeiros E. oleracea e E. precatoria cultivados na região metropolitana de Manaus, Amazonas. |

The genotoxicity induced by pesticides applied in an IPM program were evaluated with four plant bioassays. Three pesticide application rates were prescribed as follows: (a) Low - no field pesticide spray; (b) Medium - IPM test rate: banded cyanazine plus metolachlor (2.7 kg a.i. and 2.3 L a.i./ha of herbicides, respectively; and (c) High - preventative pesticide application program: broadcast cyanazine plus metolachlor (same application rates as above) plus chlorpyrifos (1 kg a.i./ha of insecticide). The Tradescantia micronucleus assay was employed for the assessment of (a) the formulated compounds, singly and combinations; (b) pesticide residues extracted from soils sampled before and after application, and (c) in situ exposures (14-hr exposure to pesticide-sprayed field). All pesticides showed clastogenic potency at doses below 50 ppm. Aqueous extracts of the two pesticide-sprayed soils were clastogenic, but the unsprayed soil extracts were not. Plants exposed in situ to pesticide-sprayed soils also showed significant increases in micronuclei frequency in relation to controls exposed to unsprayed soil. This genotoxic activity also induced increases in the mutation rate detected in situ by the Tradescantia stamen hair assay, the soybean leaf mosaicism assay, and the corn waxy pollen assay. In general, there was no significant reduction in the genotoxic effects from the High to the Medium treatment levels of the IPM program. This suggests that the reduction in pesticide application rates attained with the implementation of the proposed IPM program was not sufficient to abate the genotoxicity of the pesticides, as perceived with the sensitive assays employed. The results indicate that replacing genotoxic compounds may be the only effective remediation measure to eliminate the risks imposed by mutagenic compounds in the agricultural environment.
