“…respectively (Table 2). The isolates were identified morphometrically, the Colletotrichum conidia were straight, cylindrical, with an obtuse apex and a truncated base; the average size was 13.2 x 4.2 μm, which correspond to the values indicated by Sutton 26 for Colletrotrichum gloesporioides. In the case of Lasiodiplodia conidia, the average size was 22.82 x 11.06 μm, located in the range indicated by Punithalingam 27 for Lasiodiplodia theobromae.…”

Mango anthracnose in mango in the tropical and subtropical regions of Mexico is a disease that induces serious economic losses, caused by Colletotrichum gloesporioides. The objective of this research was to determine the efficiency of integrated management for anthracnose control and to identify the critical moment for disease management. The work was carried out on cv. 'Ataúlfo', in Guerrero, Mexico, in three production cycles. The identification of the pathogen was confirmed and during a period of 11 months the abundance of spores in the canopy of the trees was examined. Three treatments were evaluated: integrated management with severe pruning (MIM-Pruning), integrated management without severe pruning (MIM) and Control treatment. The climate was conducive to the development of the disease (>80% incidence). The greatest increase in spores, with 65.9 to 84.1 spores/week, was observed during summer vegetative growth, in the phase of flowering and fruit set on the rachis, with its subsequent decrease in fruit growth. The MIM-Pruning and MIM treatment showed consistent results of less area under the disease curve progress (AUDCP), in foliage and flowering, causing a greater definitive fruit set per inflorescence and marketable fruits per tree with respect to the Control (P ≤0.05). Field pathogen population management should begin with the spraying of fungicide products in the summer vegetative growth phase and before the full flowering stage. Pruning is a practice that should be included in anthracnose management.

“…Previous research showed that T. harzianum and T. viride exhibited strong inhibitory activities against S. fuliginea , with 44.07% and 39.72% control efficiency, respectively ( 41 ). T. harzianum suppressed strawberry powdery mildew damping-off effectively ( 42 ). T. harzianum T39 spray reduced the severity of powdery mildew by 97%; however, as the epidemic progressed, its effectiveness dropped to 18 to 55% ( 43 ).…”

Trichoderma asperellum is widely found in plant roots and soil and has been used for the biocontrol of various plant pathogens; however, the control efficiency of T. asperellum is usually unstable in field trials. To improve the control efficiency of T. asperellum , in the present study, T. asperellum microcapsules were prepared using sodium alginate as wall material to reduce the effects of temperature, UV irradiation, and other environmental factors on its activity, and to significantly improve its biocontrol efficiency on cucumber powdery mildew.

“…In the current context of global demands for the reduction of pesticides and agrochemicals (i.e. United States Environmental Protection Agency 2017), the identification of new biocontrol agents is essential for a sustainable agricultural practice (Berg 2009, Es-Soufi et al 2020. Native biodiversity can be a constant source of these new bioresources (i.e.…”

Phytopatogenic fungi cause severe economic losses worldwide. Rhizoctonia solani Kühn is a pathogenic fungi affecting several crops, controlled mainly by agrochemicals. Biological control has arisen as another option for managing this pathogen. In this study, we evaluated the biocontroller potential of five orchid mycorrhizal fungi (OMF) isolated from terrestrial Chilean orchids on R. solani. We compared the biocontroller effect of these OMFs with that of Trichoderma harzianum Rifai in an in vitro dual culture experiment. We found that R. solani can be controlled in vitro by OMF isolated from native orchids. The OMF isolated from Chloraea virescens and C. lamellata showed the best biocontroller results, which were similar, or even higher, than with T. harzianum. Thus, OMFs could become a relevant alternative for the integral control of R. solani, contributing to the reduction in the use of agrochemicals in crops.
