Tridge summary

Through laboratory studies and in collaboration with Senave, the presence of the two variants of the fungus Diaporthe, which causes the disease known as soybean anomaly, was confirmed in various productive areas of the country, mentioned in Nación Productiva Agricultural Engineer Wilfrido Morel, director of FitoLab Paraguay, who also noted that, while the infection occurs in the vegetative phase, the symptomatic aspects, such as the breaking of stems and the rotting of pods and grains, are observed from the reproductive stage.

In the Sunday agroclassic, where this new threat to production, the soybean anomaly, was addressed, the Paraguayan phytopathologist pointed out that the disease is characterized by a break or rupture of the stem about five centimeters from the ground, causing the plant to break and fall, leading to a loss of productivity. He added that if it reaches the grain formation stage, it causes the grains to rot inside the pod. "It was possible to determine through isolates from various productive areas the presence of the fungus in our country," he emphasized. He recalled that symptoms had already been observed in the Itakyry area (Alto Paraná) in 2016. "We had to visit a commercial area where there was a complaint about a genetic material. We went to that place and it presented that symptom of stem breakage, we brought the sample, but we could not confirm if it was the fungus, as it is done through molecular studies in specialized laboratories," he noted. He added that in the last ...
