Controle químico da brusone em arroz de terras altas: efeitos nos fungos não alvos do filoplano

Abstract: A brusone em arroz de terras altas causa danos significa-tivos, necessitando de uma a duas aplicações de fungicidas, para o controle da doença. No entanto, o efeito de fungicidas sobre fungos não alvos do filoplano do arroz e benéficos são desconhecidos. Este trabalho objetivou avaliar o efeito de fungicidas no controle da brusone nas panículas, sobre fungos não alvos do filoplano de arroz, e estudar a antibiose de fungos não alvos para M. oryzae. Foi realizado um experimento em campo, utilizando-se duas culti… Show more

“…Silicon (Si) is the second most abundant element in the earth’s crust and its effect on organisms may be different, serving as a cellular chemical element or providing a natural morphological modification [ 7 , 8 , 9 , 10 , 11 ]. As a cellular chemical element, it plays an important role in the mineral nutrition of plants, aiding development by increasing the organism’s biomass.…”

“…As a cellular chemical element, it plays an important role in the mineral nutrition of plants, aiding development by increasing the organism’s biomass. Furthermore, it also increases resistance to biotic and abiotic stresses, such as diseases and pests, excess of toxic metals, saline stress, water deficiency, among others [ 7 ]. Some studies indicate that Si affects the nutritional status of crops, and thus, it is believed that Si influences nutrient absorption and nutritional efficiency of plants.…”
