Conteúdo:  ABSTRACT: Sudden death syndrome (SDS) caused by the soilborne fungus Fusarium solani f. sp. glycine (FSG) is a major disease in soybean [Glycine max (L.) Merr.]. Slecetion for SDS resistance in the field is difficult because of the impact of the environment on disease development. The objective of my first study was to evaluate the effect of field inoculation methods, soil compaction, and irrigation timing on the occurrence of SDS symptons. Six treatments which included FSG infested grain of white sorghum [Sorghum bicolor (L.) Moench], popcorn (Zea mays everta) or oat (Avena sativa L.) were planted in the furrow with the soybean seed, broadcasted and incorporated into the soil prior to planting or placed below the soybean seed just prior to planting. Three experiments were also conducted to evaluate the effect of compaction and irrigation on SDS symptom occurrence. Irrigation treatments that included water application at V3, V7, R3, R4 and/or R5 growth stages were applied. In all experiments disease incidence (DI) and disease severity (DS) ratings were taken to evaluate foliar SDS symptom and a disease index (DX) was determined. The inoculation methods that produced the most severe foliar symptom included placing infested sorghum below the seed prior to planting (DX=36.1) and planting infested popcorn in the furrow with the soybean seed (DX=28.7). No significant effects of soil compaction on SDS foliar symptom development were observed. The irrigation treatments during mid t... Mostrar Tudo
