The effects of spent mushroom compost and municipal solid waste compost onPhytophthora drechsleriin vivo and in vitro

Abstract

Leached spent mushroom compost (SMC), municipal solid waste compost (MSWC) and their extracts, were tested to suppress Phytophthora drechsleri in cucumber plants. The composts were mixed with sand-loam soil in sterile and non-sterile types and were used to assess suppressiveness against P. drechselri in greenhouse experiments. The extracts of composts, in both sterile and non-sterile types, were applied to evaluate their effect in suppression of pathogen in vitro. The results of the experiments showed that all applications rate of non-sterile SMC were significantly effective in the control of the pathogen. However the sterile SMC amendments did not have a positive effect on the pathogen suppression in vitro or in vivo, as it was expected. In greenhouse experiments, both composts were effective in controlling pathogen at the rate of 15%, but the treatments amended with higher rate of MSWC did not show a positive effect. The treatments amended with MSWC (15%) and SMC (25%) showed the most suppressive effect in controlling the pathogen. The extract of leached-SMC could inhibit P. drechselri in petri dish.

Effect of Aerated Compost Tea on the Growth Promotion of Lettuce, Soybean, and Sweet Corn in Organic Cultivation

“…To date, majority of the studies have focused on plant disease control and suppressive ability of compost tea ( Goonani et al, 2011 ; Litterick et al, 2004 ; Weltzien, 1992 ). A little plant disease control studies are available on aerated compost tea or non-aerated compost tea.…”

The potential of Spent Substrate of Oyster (Pleurotus ostreatus) dan Shiitake (Lentinula edodes) Mushrooms to Control Damping-off Disease (Rhizoctonia solani) in Tomato

“…Selain itu, limbah media jamur konsumsi juga berpotensi untuk mengendalikan penyakit tanaman (Suess & Curtis, 2006). Limbah media jamur kancing (Agaricus bisporus) dilaporkan dapat menekan penyakit rebah semai pada seledri yang disebabkan oleh Phytophthora drechsleri (Goonani et al, 2011). Kompos bekas media jamur Tiram P. ostreatus dan P. sajor-caju dapat menekan jumlah sista Heterodera schachtii pada tanaman gula bit (Palizi et al, 2009).…”

The Potential of Microbes Isolated from Spent Substrate of Shiitake and Oyster Mushrooms to Induce Resistance Against Early Blight Disease in Tomatoes

“…The ability of spent substrate from shiitake and oyster mushrooms to control plant disease has been documented. Spent shiitake and/or oyster mushroom substrates have been reported to control bacterial wilt disease (Ralstonia solancearum) in potatoes [4,5], stem-based rot in onions [6], damping off disease (Phytophthora drechsleri) in cucumbers [7], damping off disease (Rhizoctonia solani) in tomatoes [8] and late blight disease (Phytophthora capsici) in peppers [9]. Spent mushroom substrate can control plant diseases through several mechanisms.…”

“…Spent mushroom substrate can control plant diseases through several mechanisms. The efficacy of spent mushroom compost has been related to the activity of microorganisms that are antagonistic to plant pathogens [7,[10][11][12]. Spent mushroom substrates also contain antimicrobial substances that inhibit pathogen growth [13,14].…”
