Asian Soybean Rust Development in Sintomas e sinais Os primeiros sintomas da ferrugem da soja causada por Phakopsora pachyrhizi iniciam com diminutas manchas de cor marrom castanha, pt ou vermelho-tijolo nas folhas Figura 2. ABSTRACT Aiming to quantify the severity of Asian rust, the content of the chlorophylls a and b and carotenoids as well some nutritional aspects of soybean plants supplied with silicon in the form of soluble potassium silicate solution an experiment was carried out in a random block design with 6 treatments and four replicates.

At the end of experiment, shoots from plants that received increasing silicon doses were sampled in order to analyze the chlorophyll a and bcarotenoids, lignin, macro and micronutrients.
