| Sumario: | Papaya is a crop of great importance worldwide, Mexico and Colombia are world leaders in its production; one of the main limitations for this crop is the diseases that include the anthracnose that affects pre and post harvest, which is why research in the search for efficient, sustainable and harmless alternatives in crop health are essential to reduce losses in production and thereby improve the income and quality of life of the producer and those involved in the production chain to the consumer with quality products and without contaminants that affect their health. The objective of this study was to evaluate plant extracts under two forms of extraction in the in vitro control of Colletotrichum gloesporioides. Therefore, the antifungal effect of plant extracts of oregano leaves (Oreganum vulgare), pepper fruits (Pimienta dioica), neem leaves (Azadirachta indica) and dried marathon leaves (Gliricidia sepium) obtained from methods was evaluated: distillation and microwave, on C. gloesporioides isolated from Carica papaya. The technique of poisoned medium in Petri dishes with PDA medium was used, in a first phase the concentration of 60 % was tested for all extracts. Subsequently, the minimum inhibitory concentration was determined for those who in the first phase inhibited 100 %. The antifungal effect was determined by mycelial growth, number of total and germinated conidia. The results indicated that the extract of pepper fruit obtained by microwave in a concentration of 40% and M2 UNACH patent of 20 % inhibited C. gloesporioides t. the extracts obtained by the microwave had better antifungal effect than those obtained by distillation. |
