The drop of the potato or late blight is one of the most aggressive diseases that attack the potato crops and in a short time destroys them, causing great economic losses, it is produced by the phytopathogen Phytophthora infestans, oomyceto that has taken great importance due to its devastating effects and difficulties in achieving its eradication. Fungicides of a chemical nature represent a problem due to the affected use, which makes  it very difficult to eliminate the disease due to the appearance of new resistant species. There are new alternatives for its control, based on the use of substances of the plant nature, and the application of new specific tools to perform gene editing, reprogram or eliminate DNA / RNA sequences, thus favoring the obtaining of cultures free of toxic substances . In this review, specific biocontrol methods are presented, such as essential oils, microbial metabolites, molecular tools and the use of biodegradable substances that favor the management and prevention of pests, which help mitigate the environmental problems generated by the use of fungicides from chemical nature.
