RIVERA AMITA, María Magdalena; MILANES FIGUEREDO, Masgloiris  e  RAMOS GALVEZ, Silvino Raúl. Method of control of the main pests, diseases and underbrush in Calendula officinalis L. Rev Cubana Plant Med [online]. 2005, vol.10, n.1, pp. 0-0. ISSN 1028-4796.

In the Cuban conditions, the Calendula officinalis L. species is affected by insects and underbrush. Different fungi in its leaves and flowers also produce diseases. In order to control pests and diseases, 2 pesticides of plant origin were used: tabaquina, a by-product of tobacco (Nicotiana tabacum L) and dry macerated seeds of chinaberry (Melia azederach L.) extracted by repercolation with ethanol 70 % and a product of biological origin obtained from the mixture of Beauveria bassiana, Verticillum lecanii and Trichoderma viridis fungi with the Bacillus thuringiensis bacterium. Each treatment was replicated 3 times and included a control. To control underbrush, it was only used the cultivation method by weeding and hoeing. The methods used for the control of the most harmful pests and diseases proved to be effective, excepting the control of Trips that were resistant to all the tested products, which may result from the contiguity between cultivations.
