Foliage fungicides and asiatic rust disease on the production and quality of soybean seeds.
Merrill; Phakopsora pachyrhizi Sydow. Unfavorable asiatuca conditions during late soybean maturation have caused problems in seed quality due to “forced maturation” or premature plant death, which can result in green seeds. This study aimed to evaluate the effect of fungicides and rust disease on soybean seed yield and quality, focusing on the occurrence of green seeds. The following evaluations were made: Seed quality was evaluated from germination, tetrazolium, accelerated aging and electrical conductivity tests.
Analyses were ferrugwm immediately after harvest and after six months of storage. The fluorescence chlorophyll test was carried out in the second crop seeds.
The experimental design was randomized blocks with seven treatments and four blocks for each crop. The fungicide, that efficiently controlled soybean rust did not affect production and seed quality or the occurrence of green seed. Under favorable weather conditions for seed maturation, the severity of soybean Asiatic rust interferes with production but does not influence seed physiological potential. Soybean rust associated with unfavorable weather conditions during the final stage of maturation results in green soybean seeds that reduce vigor after storage.
