Alternative products in the "in vitro" inhibition of Sclerotinia sclerotiorum

Abstract: The white mold, caused by Sclerotinia sclerotiorum, is a very important disease in tomato crops. The objective of this work was to study the effect of plant extracts, animal residues and industrial byproducts extracts on the fungus in vitro growth. Treatments consisted of different concentrations of pyrolignous oil, neem oil, monosodium glutamate, sewage sludge and organic compost [coffee residue (50%) coal residue (10%), maize residue (25%), poultry waste (12.5%), poultry meal (2.5%)]. Positive control consis… Show more

“…(Sangeetha and Jahagirdar, 2013) where as in the present study neem extract stimulated the growth of R. solani instead of inhibiting the growth. It was also not found effective against S. sclerotiorum, contradicting with the results of Mello et al(2005). However, it reduced the growth of F. solani by 13% but was not significant compared to control.…”

“…Plants fertilized with compost had 27.78% disease severity percent while animal and chicken manure were conducive for the disease progression which resulted in higher disease severity levels. The importance of inhibitory effect of organic fertilizers on white mould disease of beans was previously discussed and confirmed by El -Masry et al (2002), Mello et al (2005) and Lahoz et al (2009).…”

“…They found that fungistasis could be one of the possible mechanisms of action and the extract was not phytotoxic. The suppressive action of organic fertilizers was supported by the findings of El-Masry et al (2002)andMello et al (2005).…”

“…Ao se estudar a inibição de aflatoxinas por extrato de folhas e sementes de nim, verificou-se que o extrato aquoso contendo 50% das folhas de nim inibiu 90% da produção de aflatoxinas em micélios fúngicos de A. parasiticus, enquanto o extrato de sementes inibiu apenas 65%. Em estudo realizado por Mello et al (2005) o óleo de nim reduziu o crescimento micelial e a formação de escleródios de Sclerotinia sclerotiorum nas concentrações de 0,25, 0,5 e 2%.…”

“…A atividade antifúngica de produtos naturais obtidos de nim frente a fungos fitopatogênicos já foi relatada por diversos autores (MEDICE et al, 2007;CARNEIRO et al, 2007;MELLO et al, 2005;SINDHAN et al, 1999;CARNEIRO et al, 2008). Devido a essa atividade, o óleo de nim tornou-se um produto comercial, sendo indicado na agricultura para pulverizações em geral, entretanto o preço do produto pode restringir seu uso.…”
