Abstract
Abstract Asian soybean rust ( ASR ), caused by P hakopsora pachyrhizi , is one of the most important diseases on soybean. At the moment, ASR is managed mainly with fungicides due to the absence of commercial cultivars with resistance to this disease. This study evaluated the effects of acibenzolar‐Smethyl ( ASM ), jasmonic acid ( JA ), potassium silicate ( PS ) and calcium silicate ( CS ) on soybean resistance to ASR . The ASM , JA and PS were sprayed to leaves 24 h prior to inoculation with P. pachyrhizi . The CS was amended to the soil. The incubation period (time from the inoculation until symptoms development) was longer for plants growing in soil amended with CS or sprayed with ASM in comparison with plants sprayed with water (control). Plants sprayed with ASM had longer latent period (time from the inoculation until signs appearance) in comparison with the control plants. Plants sprayed with PS showed fewer uredia per cm² of leaf in relation to the control plants. The ASM and PS were the most effective treatments in reducing the ASR symptoms in contrast to the JA and CS treatments. The JA served as an inducer of susceptibility to ASR .
