Tagetes patula L. is a prominent plant that is frequently used for its ornamental value. Marigolds are sources of various compounds of great interest to agricultural, pharmaceutical, and nutritional industries. Microalgae can be applied as a biostimulant as they have multifunctional properties in agriculture, namely facilitating nutrient uptake, improving crop performance and physiological status, and thus incr...
This study evaluated the effect of Chlorella vulgaris application on the growth of soilless-grown lettuce (Lactuca sativa cv. 'Oreja de Mulo') cultivated outdoors. Microalgae suspensions were applied weekly at concentrations of 0.5, 2.0, and 5.0 g L(-)1. Plants grown without the application of microalgae were used as the control. Leaf chlorophyll concentration was registered at the beginning and at the end of t...
Composts can be used to improve soil fertility while controlling soil diseases, contributing to the circular economy in agriculture. Biological control of soil diseases may be achieved by the activity of antagonistic microorganisms, that, by different ways, prevent the development of phytopathogenic microorganisms, being Trichoderma spp. one of the best-known antagonistic fungi. In this work, the evolution of t...
Chlorella vulgaris and Tetradesmus obliquus were tested as biocontrol agents against the phytopathogenic fungus Fusarium oxysporum. This evaluation was conducted through in vitro and in vivo trials with spinach (Spinacia oleracea L.). The in vitro trials showed that C. vulgaris and T. obliquus were able to inhibit the phytopathogen, showing a similar inhibitory effect to that of the positive controls (Rovral, B...

Soilless cultivation is increasingly common, but the nutrient-rich drainage from substrate cultivation is often discarded. However, drainage can be safely reused if previously disinfected. Slow sand filtration (SSF) is a lowcost, ecological, and effective method for water disinfection, primarily through biological control. Enhancing SSF with antagonistic microorganisms is not well-studied. Additionally, SSF has...
