“…On the other hand, Kim et al (1997) reported that sewage sludge did not interfere with the incidence of root and crown rot caused by Phytophthora capsici in pepper. Similar results were obtained by Ghini et al (2007) with Fusarium oxysporum in tomato and Lumsden et al (1983) with Pythium in bean and pea. Finally, there are also reports of increased diseases as a consequence of sewage sludge incorporation, for example those caused by Fusarium spp.…”

“…Such toxicity could have weakened the plants and made them more susceptible to the pathogen. Leoni and Ghini (2006) and Ghini et al (2007) reported a temporary phytotoxicity when large volumes of sewage sludge were incorporated to the soil, which were attributed to heavy metals and salinity. Analyses of the sewage sludge used in this work revealed the presence of both heavy metals and soluble salts.…”

Growth, yield and physiology of Verticillium-inoculated pepper plants treated with ATAD and composted sewage sludge

et al. 2009

A greenhouse experiment was conducted to investigate the impact of sanitized sewage sludges, ATAD (aerobic thermophilic autothermic digestion) and composted, on Verticillium-induced wilt in pepper plants (Capsicum annuum L. cv. Piquillo). Two doses of ATAD (15 and 30% v/v) and three of composted sludge (15, 30 and 45% v/v) were applied to a peatbased potting mix. Unamended substrate was included as control. Half of the plants were inoculated with V. dahliae, whereas the other half remained noninoculated. Result showed that ATAD and composted sludge increased growth and yield of non-inoculated plants. V. dahliae reduced net photosynthesis (P n ), mainly as a consequence of stomatal closure, 5 weeks after pathogen inoculation. The actual photosystem II efficiency was also reduced and consequently the electron transport rate (ETR). No photoinhibitory damage was observed at this time in diseased plants. At the end of the experiment, diseased plants showed lower plant biomass and fruit yield. ATAD sludge had little effect on the disease. Compost slightly alleviated Verticillium-induced wilt when applied at lower doses (15% v/v), which resulted in increased P n and ETR, and higher plant biomass and fruit yield. By contrast, higher doses of compost (45% v/v) enhanced the effect of the pathogen, which was related to the high substrate salinity in this treatment.

“…The interaction between hosts and pathogens (Termorshuizen et al, 2006;Ghini et al, 2007) can differ in the power of soil suppressiveness, due to the specificity and ecology of the causal agent in soil. For example, the soil inhabitant pathogen R. solani has a saprogenic stage and can grow in organic matter while Verticillium need a host to survive (Postma et al, 2008).…”

Sandy soils of 19 arable fields were analyzed for disease suppressiveness against root rot disease of cassava, caused by Fusarium solani CFF109. Analysis of chemical, physical, biochemical, microbial population and activity, and soil characteristics were assessed. Soils with different management histories and covers most commonly found in the region were collected to build a greenhouse experiment, to evaluate the natural suppressiveness of soils against cassava root rot. The severity was submitted with all data across correlation and multivariate analyses to find correlation between disease suppressiveness and abiotic or biotic soils attributes. Differences in disease suppressiveness were found between the treatments for cassava root rot. Significant disease suppression was found in 37% of the soils. The sandy soil covered with consortium of Zea mays + Vigna unguiculata was the most efficient in suppressiveness against disease caused by F. solani. The data indicated significant correlation between soil characteristics and suppressiveness cassava root rot. The soil supressiveness against cassava root rot was favored by increase by total bacteria, fluorescent group bacteria populations and activity of acid and alkaline phosphatase and β-glucosidase.

To what extent are soil amendments useful to control Verticillium wilt?

The genus Verticillium includes several species that attack economically important crops throughout the world. The control of Verticillium spp. becomes especially difficult when they form microsclerotia that can survive in the field soil for several years. It has been common practice to fumigate soil with chemicals such as methyl bromide and/or chloropicrin to control soil-borne fungal pathogens. Other chemicals that are used against Verticillium spp. are the antifungal antibiotic aureofungin, the fungicides benomyl, captan, carbendazim, thiram, azoxystrobin and trifloxystrobin and the plant defence activator acibenzolar-S-methyl. However, the potential risks involved in applying phytochemicals to crop plants for both the environment and human health, together with their limited efficacy for controlling Verticillium-induced diseases, support the need to find alternatives to replace their use or improve their efficacy. Soil amendment with animal or plant organic debris is a cultural practice that has long been used to control Verticillium spp. However, today the organic farming industry is becoming a significant player in the global agricultural production scene. In this review, some of the main results concerning the efficacy of several soil amendments as plant protectors against Verticillium spp. are covered, and the limitations and future perspectives of such products are discussed in terms of the control of plant diseases.
