    The trial was carried out on the property of Mrs. María Sacón located in Quillan Loma in the parish of Izamba, with the objective of controlling powdery mildew in the Zucchini crop through the application of plant extracts. In this trial, a Completely Randomized Block Experimental Design (DBCA) was used with a factorial arrangement of 2 extracts and 3 doses plus 1 control (2 x 3 + 1), with three repetitions at 30, 40 and 50 days, at Significant responses were applied with the Tukey test at 5%. The variables studied were incidence, severity and incubation period. The plant extracts used were chamomile and thyme each at 3 different concentrations that were 30%, 40% and 50%. The extracts with the highest concentration were those with the greatest control. In this trial, the two treatments that led in the lowest incidence 30 days from their first application were E2D3 (71.72%) and E1D3 (73.03%), in severity E2D3 (22.36%) and E1D3 (23.13%) denote a very notable difference with respect to the control, ending with 98.03% incidence and 50.50% severity. In addition, we also have that the incubation period occurred between days 6, 7 and 8 after the transplant, reflecting that it occurred very soon, this was because favorable conditions existed for the development of this disease.
