Resumo: The objective of this study was to analyze the effects of glandular secretion extracts from Rhaebo guttatus and Rhinella marina on TMG 132 RR soybean cultivar against the fungi Phakopsora pachyrhizi. Thirty days after seeding, a spontaneously arise of the disease was noticed and, two days after the arise of the first pustules, plants were treated with glandular secretion extracts at the concentrations 0,1; 0,2; 0,3; 0,4 e 0,5 mg mL-1, acibenzolar-S-methyl (500 L ha) and distilled water. None of the treatments resulted in statistical differences at the photosynthetic rates of the plants for chlorophyll a, chlorophyll b and total chlorophyll content. Glandular secretion extracts of R. guttatus and R. marina were not effective to reduce disease severity. There wasn’t statistical difference among treatments for defoliation percentage. For the biometrical evaluations, glandular secretion extracts of R. guttatus resulted in statistical difference only for the variable plant height but not for the remaining variables. Glandular secretion extracts of R. marina resulted in statistical difference only for number of root nodules but was not significant for the remaining variables.

Assim, este estudo analisa os efeitos de extratos de secreções glandulares de Rhaebo guttatus e Rhinela marina contra o fungo Phakopsora pachyrhizi e na biometria de plantas de soja da cultivar TMG 132 RR. Aos 30 dias após semeadura, notou-se o surgimento espontâneo da doença e, dois dias após o surgimento das primeiras pústulas, as plantas foram tratadas com extratos de secreções glandulares nas concentrações de 0,1; 0,2; 0,3; 0,4 e 0,5 mg mL-1, acibenzolar-S-metil (500 L ha) e água destilada. Com relação ao número total de trifólios, teores de clorofila a, b e total não houve diferença estatística entre os tratamentos. Nas avaliações biométricas, o extrato de secreção glandular de R. guttatus proporcionou diferença estatística apenas na variável altura de plantas. Quando as plantas foram tratadas com extrato de secreção glandular de R. marina, houve diferença estatística no número de nódulos, porém, sem diferença estatística para as demais variáveis analisadas. Conclui-se que extratos de secreções glandulares de R. guttatus e R. marina não controlam ferrugem asiática da soja; porém concentrações de 0,1mg mL-1, 0,2 mg mL-1 e 0,3 mg mL-1 de extrato de secreção glandular de R. guttatus promovem maior altura de plantas e extrato de secreção glandular de R. marina, nas concentrações de 0,1mg mL-1, 0,2 mg mL-1 e 0,4 mg mL-1, afeta negativamente o número de nódulos.

Thus, this study assessed the effects of glandular secretion extracts from Rhaebo guttatus and Rhinella marina against the fungi Phakopsora pachyrhizi and biometric responses on TMG 132 RR soybean cultivar. Thirty days after seeding, a spontaneously arise of the disease was noticed and, two days after the arise of the first pustules, plants were treated with glandular secretion extracts at the concentrations 0,1; 0,2; 0,3; 0,4 e 0,5 mg mL-1, acibenzolar-S-methyl (500 L ha) and distilled water. None of the treatments resulted in statistical differences at the photosynthetic rates of the plants for chlorophyll a, chlorophyll b and total chlorophyll content. For the biometrical evaluations, glandular secretion extracts of R. guttatus resulted in statistical difference only for the variable plant height variable. Glandular secretion extracts from R. marina resulted in statistical difference only for number of root nodules but was not significant for the remaining variables. The results showed that glandular secretion extracts from R. guttatus and R. marina does not control Asian soybean rust; however glandular secretion extracts from R. guttatus at the concentrations 0,1mg mL-1, 0,2 mg mL-1 e 0,3 mg mL-1 promotes greater plant height. The glandular secretion extracts from R. marina at the 0,1mg mL-1, 0,2 mg mL-1 e 0,4 mg mL-1 negatively affects the number of plant nodules.
