• Abstract

  Soybean losses due to biotic diseases can directly impact food security due to its global importance and multiple uses as human and animal feed. Anthracnose is caused by several species of the genus Colletotrichum, with C. truncatum and C. orchidearum being the most representative complexes. While studies related to C. truncatum have advanced in recent years, the understanding of the inte…

• Abstract

  The large soybean cultivation in Brazil, mostly under monoculture and non-tillage system, affects the intensity of diseases. Amongst them, anthracnose is the most prominent, as soybeans are susceptible to infection at all stages of development. Frequent reports on the increase incidence in the northern and mid-western regions indicate that chemical control program for fungal diseases in s…

• Abstract

  Seedborne pathogenic fungi can cause severe losses to soybean crop due to the diseases they cause, as well as direct damage to the seeds such as lower germination, vigor and seedling emergence.The detection and accurate identification of pathogens is one of the most important strategies to start a preventive and curative control of plant diseases. To prevent the introduction and spread in…

• Abstract

  Since the beggining of time, rust fungi have been among the pathogens responsible for some of the most destructive diseases in cultivated and non-cultivated plants worldwide. Among these diseases is Myrtle Rust, caused by Austropuccinia psidii, that is becoming a growing threat to this plant family. Brazil is the center of origin of A. psidii, and currently Myrtle Rust is widespread, asso…

• Abstract

  Colletotrichum sp. is the causal agent of anthracnose on soybean. Morphologically-based identification of Colletotrichum species has always been problematic, because there are few reliable characters and many of these characters are plastic. Recent papers have shown that a strong, solid characterization is obtained when different methods are employed together, the so-called polyphasic app…

• Abstract

  Colletotrichum guaranicola is the causal agent of anthracnose on leaves and fruits of guarana (Paulinia cupana), an important crop in the Brazilian agricultural business. Accurate species identification is critical to understand the epidemiology and developing effective control of this disease. The conventional identification of Colletotrichum species is based on morphological characters,…

• Abstract

  Myrtle rust, caused by Austropuccinia psidii, is responsible for significant economic, environmental, and social impacts. A. psidii is an obligate biotroph that has its asexual dikaryotic stage associated with epidemic outbreaks around the world. Brazil is the center of origin of A. psidii, and currently, myrtle rust has a wide host range, associated with more than 480 species in the Myrt…
