| Description: | 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. La gota de la papa o tizón tardío es una de las enfermedades más agresivas que atacan los cultivos de papa y en poco tiempo los destruye, ocasionando enormes pérdidas económicas, es producida por el fitopatógeno Phytophthora infestans, oomyceto que ha tomado gran importancia debido a sus efectos devastadores y las dificultades para lograr su erradicación. Los fungicidas de naturaleza química representan un problema debido al uso inadecuado, lo que hace muy difícil eliminar la enfermedad por la aparición de nuevas especies resistentes. Existen nuevas alternativas para su control, basadas en el uso de sustancias de naturaleza vegetal, y la aplicación de nuevas herramientas capaces de realizar edición de genes, reprogramar o eliminar secuencias de ADN/ARN, favoreciendo así, la obtención de cultivos libres de sustancias tóxicas. En esta revisión, se presentan los métodos existentes de biocontrol: como aceites esenciales, metabolitos microbianos, herramientas moleculares y el uso de sustancias biodegradables que favorecen el manejo y prevención de plagas, que ayudan a mitigar la problemática ambiental generada por eluso de fungicidas de naturaleza química. |
