ABSTRACT The production of sisal in Bahia, Brazil, has been declining due to the occurrence of a disease know as bole rot. Aspergillus niger was regarded as the only causal agent. In this study A. brasiliensis and A. tubingensis, in addition to Aspergillus niger, identified on the basis of morphological and molecular analyses, were shown to cause bole rot of sisal. Their pathogenicity was confirmed but their significance for the epidemiology of the disease in the field remains unclear.

Larvicidal activity of Agave sisalana against Aedes aegypti mosquito, the dengue vector
Background Dengue is a viral systemic disease caused by an arboviral of Flaviviridae family, affecting about a 700 thousand cases per year in Brazil. It is endemic in tropical regions such as Southeast Asia, South Pacific, East Africa, Caribbean and Latin America. The disease is transmitted by Aedes aegypti (Linnaeus, 1762), a mosquito that is the main target for the disease control through str...

The leaf extract of Agave sisalana was tested as a larvicide against three vector mosquito species viz., Anopheles stephensi, Culex quinquefasciatus and Aedes aegypti. Preliminary results showed that the 2% dilution of the leaf extract produced 100% mortality of IIIrd instar larvae of An. stephensi and 1% dilution produced 100% mortality in case of Cx. quinquefasciatus and Ae. aegypti. For furt...

It was evaluated the anthelmintic activity of Agave sisalana (sisal) juice against gastrointestinal nematodes and its potential toxic effects in goats. In vitro tests showed more than 95% reduction in larval counts of the genus Haemonchus spp. at concentrations between 86.5 and 146.3 mg.mL(-1). In vivo the percent reduction of larvae of the fourth (L4) and fifth (L5) stages of Haemonchus, Oesop...
