The new species Trichoderma martiale was isolated as an endophyte from sapwood in trunks of Theobroma cacao (cacao, Malvaceae) in Brazil. Based on sequences of translation-elongation factor 1-alpha (tef1) and RNA polymerase II subunit (rpb2) T. martiale is a close relative of, and morphologically similar to, T. viride, but differs in the production of discrete pustules on corn meal-dextrose aga...

Paulownia species are fast growing trees native to China, which being grown in managed plantings several European countries for the production of wood and biomasses. In 2018, wilting, stunting, leaf yellowing, collapse, as a consequence root crown rot, were observed around 40% 2-year-old planting elongata × P. fortunei Calabria (Southern Italy). Two Phytophthora consistently recovered from root...

This research aimed to determine the potentiality of P1 and P2 as parents produce superior strains hybrid cacao by estimating general combining ability (GCA) specific from crossed diallel among high yielding which are resistant P. palmivora . The study was conducted at Experimental Farm Sumber Asin, Malang, East Java, 2010 2018. arranged in Randomized Block Design (RBD) consisted 10 hybrids 5 s...
