understanding the function of trichoderma species in the control of phytophthora drechsleri in pistachio orchards is very important.  in this study, the effects of liquid extra-cellular secretions and volatile compounds secreted by 27 isolates of trichoderma harzianum, t. crassum, t. koningii, t.aureoviride, t. asperellum, t. brevicompactum, t.longibrachiatum and t. virens were investigated on ...

Mycotrophic species of Trichoderma are among the most common fungi isolated from free soil, dead wood and as parasites on sporocarps of other fungi (mycoparasites). In addition, they undergo various other biotrophic associations ranging from rhizosphere colonization and endophytism up to facultative pathogenesis on such animals as roundworms and humans. Together with occurrence on a variety of ...

Abstract Vascular-streak dieback (VSD) is the main disease of cacao plant caused by Ceratobasidium theobromae . The VSD can potentially reduce yields up to 45%. control using secondary metabolites Trichoderma spp. suppress incidence in field. research aimed study effectiveness controlling diseases field conditions. This performed fields owned a farmer Rahmat Village, Palolo Subdistrict, Sigi Re...

Abstract Models of speciation in African rain forests have stressed either the role of isolation or ecological gradients. Here we contrast patterns of morphological and genetic divergence in parapatric and allopatric populations of the Little Greenbul, Andropadus virens, within different and similar habitats. We sampled 263 individuals from 18 sites and four different habitat types in Upper and...

Transitions from sexual to asexual reproduction are often coupled with elevations in ploidy. As a consequence, the importance of ploidy per se for the maintenance and spread of asexual populations is unclear. To examine the effects of ploidy and asexual reproduction as independent determinants of the success of asexual lineages, we sampled diploid sexual, diploid asexual, and triploid asexual E...
