One of the most damaging diseases in cultivation of avocado (Persea americana Mill.) is root rot associated with Phytophthora cinnamomi Rands. This disease causes progressive wilt and even death of the tree. The objective of this study was to identify the presence of P. cinnamomi in two productive areas of avocado in Ecuador using the molecular technique PCR-RFLP. Tree root samples were obtained with root rot symptoms ...
Whitefly (Paraleyrodes sp.) preference for avocado cultivars (Persea americana Mill.) in Fresno, TolimaPreferencia de mosca blanca (Paraleyrodes sp.) por cultivares de aguacate (Persea americana Mill.) en Fresno, Tolima

The whitefly is a major pest that affects avocado and there is not enough information about the biology and management of this insect in Colombia. In this paper the incidence of the whitefly Paraleyrodes sp. pos. bondari on four avocado cultivars was studied (Choquette, Hass, Lorena, Santana). The crop management carried out by farmers was characterized and its effect on the white fly presence on three cultivars was ...
Research advances on the productive behavior of avocado trees (Persea americana Mill.) under subtropical conditionsAvances en investigación sobre el comportamiento productivo del aguacate (Persea americana Mill.) bajo condiciones subtropicales.
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2011)
Advances in the research on avocado cultivation are generally associated with major global producers (Chile, Mexico, and the United States). The issues that have been the subject of research are focused on the study of productive performance of the species under subtropical conditions. Research topics include studies on hormonal and nutritional factors associated with the growth and development of the avocado crop in ...
Relationship between the presence and damage of Monalonion velezangeli Carvalho & Costa and some climatic factors in avocado cv. Hass cropsRelación entre la presencia y el daño de Monalonion velezangeli Carvalho & Costa y algunos factores climáticos en cultivos de aguacate cv. Hass
(Corporación Colombiana de Investigación Agropecuaria (Agrosavia), 2015)
The effect of environmental factors on populations of Monalonion velezangeli Carvalho & Costa was studied in avocado cv. Hass planted in the Colombian Andes. Climate data for the 2010-2011 period were obtained from six automatic weather stations. Insect activity was monitored by recording the presence of M. velezangeli individuals and fresh damage signals on 12 tagged branches per tree, oriented towards the four ...
