Abstract

GHINI, Raquel et al. Utilization of solar collector for treatment of plant growth substrates. Bragantia [online]. 1992, vol.51, n.1, pp. 85-93. ISSN 1678-4499.  http://dx.doi.org/10.1590/S0006-87051992000100012.

Flat solar collectors were tested for the control of Sclerotium rolfsii, Rhizoctonia solani, VerticiUium sp., Meloidogyne arenaria and Cyperus rotundus (nut sedge). The equipment developed comprises, basically, gutters of aluminum with termic liner of glass wool and transparent plastic cover. The results showed that, depending upon the solar radiation, one day is required for the disinfestations of substrate infested with S. rolfsii and nut sedge, and two days for R. solani, Verticillium sp. and M. arenaria.

Keywords : Sclerotium rolfsii; Rhizoctonia solani; Meloidogyne arenaria; Verticillium sp.; solar energy.
