Última Incidence of stalk rots in corn hybrids influenced by sowing time and nitrogen rates 53 Berghetti,Juliano; Casa,Ricardo Trezzi; Ferreira,Evandro Zacca; Zanella,Eduardo José; Scheidt,Bruno Tabarelli; Sangoi,Luis. ABSTRACT Stalk rots compromise the translocation of water and nutrients, affecting grain filling. This study aimed to quantify the incidence of stalk rots in corn hybrids depending on sowing time and nitrogen topdressing rate, and to assess any correlation with grain yield. The experiment was conducted under field conditions in Atalanta, Santa Catarina state, Brazil, using a split-split-plot randomized block design. The hybrids AG 9025 PRO3 (super-early) and 30F53 VYH (early) were sown in the preferential (September 20) and late (December 5) sowing seasons with four nitrogen rates (0, 150, 300, and 450 kg·ha–1). The population density was 75,000 plants·ha–1 andthe nitrogen topdressing was carried out at the V4, V8, and V12 stages. The fungus Colletotrichum...

ABSTRACT: The fungus Fusarium graminearum was one of the first pathogens described as causing infections in rice; however, in Brazil, there is no description of its occurrence in panicles. The present study aimed to describe the symptoms caused by F. graminearum infection in irrigated rice grains. The experiment was conducted in a greenhouse in duplicate using the irrigated rice cultivar SCS 121CL and hybrid INOV CL at the R4 (flowering) stage. Two isolate of Fusarium graminearium species complex 15A (F. graminearium - 15-ADON) and FmNiv (F. meridionale - Nivalenol), was inoculated onto panicles by spraying with macroconidia and the development of symptoms was monitored until harvest. There was no difference in symptoms among isolates. Light brown spots... Tipo: Info:eu-repo/semantics/article Palavras-chave: Oryzae sativa; Gibberella zeae; Infection of grains; Symptomology.
