The anthracnosis (Colletotrichum gloeosporiodes) is the most important disease of peach palm in Brazil, but other pathogens (Phytophthora palmivora, Fusari...
Micelial growth and sporulation of black wattle (Acacia mearnsii) Phytophthora ...
Abdanur, Adriano; Santos, Alvaro Figueredo dos; Tratch, RenatoSeven Phytophthora sp. isolates from black wattle (Acacia mearnsii) were evaluated based on mycelial growth and sporangia production. The greatest mycelial growth rate were observed on carrot-agar and V-8 at 20 and at 28ºC. The isolates sporulated under liquid cultures (KNO3 solution and sterilized water) in continuous light. Sporangia were ovoid, papillated and non-caducous. All isolates were pathogenic to bla...
