Viticulture is one of the oldest agricultural activities, and its exploitation has
traditionally been limited to temperate climate zones, where the european grapevine
(Vitis vinifera) and wine originate. Given the effects of climate change, more areas
lose the capacity to grow this crop, and the tropics are presented as potential regions
for this market. In Costa Rica, viticultural activity has been reported since the mid-
20th century, however, technical information on the crop is scarce. Downy mildew,
caused by the oomycete Plasmopara viticola, represents one of the diseases
with the greatest economic impact for viticulture worldwide, as well as the most
limiting phytosanitary problem in Costa Rica. Under high humidity conditions,
the development of the pathogen is accelerated, and the host remains susceptible
throughout the crop cycle, which makes proper management of epidemics difficult.
Chemical control is the most common management strategy around the world,
however, the appearance of P. viticola populations with resistance to fungicides
has been observed in most grape vine-growing areas, hence the search for more
ecological alternatives is a necessity. Currently, Costa Rica does not have integrated
management strategies that allow sustainable production, and there is only one
registered product for protection against this pathogen. This situation justifies
paying more attention to the investigation of this pathosystem.
