SALUSTIANO, Maria Eloísa; VALE, Francisco Xavier Ribeiro do; ZAMBOLIM, Laércio  and  FONTES, Paulo César Rezende. Tomato blight management in low temperature periods. Summa phytopathol. [online]. 2006, vol.32, n.4, pp.353-359. ISSN 0100-5405.

The performance of 'Santa Clara' tomato cultivar and of 'Débora Plus' hybrid in relation to blight (Alternaria solani) development during Summer and Autumn under two cropping systems was studied in two experiments carried out in the experimental field of 'Universidade Federal de Viçosa'. Low temperatures, lack of rain or short time of leaf wetting induced low blight incidence and, consequently, neither on of the cropping systems has influenced the disease severity on both assays. 'Santa Clara' showed higher area under disease progress curve (AUDPC) values in relation to 'Débora Plus'. Application of chlorothalonil during the appearance of the first symptoms associated to the climatic factors delayed disease development in 30 days during Summer-Autumn and Autumn-Winter, reducting blight severity in 22% and 18% of AACPD values in both assays, respectively.

Keywords : Alternaria solani; Lycopersicon esculentum; control; environmental factors.
