The main variety of avocado grown in Peru destined for the international market is 'Hass', which has grown in area and production. One of the main factors that affect the crop is the presence of pathogens such as Lasiodiplodia sp, present in the coastal region of the country where almost all of it is produced. Many estates do not know exactly the moment in which there is a greater pressure of inoculum in the plant and the influencing factors, causing their prevention work not to occur at the right time and generating little effect on the disease, with this investigation intends to monitor the presence of conidia of Lasiodiplodia sp. in the ‘Hass’ avocado crop in different producing areas of the Peruvian coast. The trial was carried out in four commercial orchards located in Trujillo, Ica, Barranca and Cañete where traps made with slides and vaseline were placed in cankers of the lower third of the tree canopy in lots with a high incidence of infection. The conidia traps were installed during 2019, evaluating and replacing them every two weeks until the end of 2020, the conidia count data were compared with temperature and relative humidity, as well as pruning and phytosanitary applications, being collected through surveys carried out on the estates. At the end of the evaluations, the results showed different peaks of releases of conidia, presenting in all areas a tendency to increase from the month of December that extends until March during the growth of the fruit and close to the harvest, to later be significantly reduced after pruning during vegetative growth and flowering. Temperature influenced releases, but was not a determining factor. On the other hand, applications of cupric fungicides mitigated releases.
