Solarização do solo em casa-de-vegetação e campo para o controle de Rhizoctonia solani AG-4

Abstract: Os cultivos em ambientes protegidos apresentaram uma grande expansão na década de 1990 no Brasil. O solo desses locais pode, por ser intensa e sucessivamente cultivado, se tornar infestado por patógenos como Rhizoctonia solani, responsável por tombamento e podridão de raízes em muitas espécies de plantas. O presente trabalho avaliou o emprego da solarização, dentro e fora de uma casa-de-vegetação vedada com plástico transparente, para o controle de R. solani. Quatro experimentos foram realizados, dois no verão… Show more

“…Just as observed by Patrício et al (2007), the highest temperatures observed in the present work were recorded at 1500 hours (Figure 1). The mean temperature was similar in both years evaluated, with values of 46.8ºC in the 1 st year in seedbeds submitted to solarization and 36.5ºC in bare soil,…”

“…Physical control through solarization may be a viable option for soil disinfestation, including areas under protected cultivation, where soil use is quite intensive; such treatment may be effective at 30 to 45 days in the field and at 20 to 30 days in protected environments (PATRÍCIO et al 2007). The most important effect of solarization consists in increased temperature provided by a transparent plastic film applied to the soil, causing the death of a significant part of the microorganisms present in that soil (GHINI et al 2002).…”

“…In order to characterize the substrates, pH chemical analyses, EC and N content in the form of ammonium ions (NH4 + ) and nitrate (NO 3 -) were carried out according to the methodology proposed by Abreu et al (2007) Singleton et al (1992) and Patrício et al (2007). For the detection of Pythium aphanidermatum, cucumber (Cucumis sativum) was used as an indicator plant, according to the methodology adapted from Lourd et al (1986Lourd et al ( , 1987.…”
