| Sumario: | This work aimed to evaluate different combinations of oils and mineral salts for controlling Podosphaera xanthii in squash (Cucurbita pepo) under field conditions. A squash crop of the Rocío variety was established. The treatments consisted of the combined application of salts (Potassium Bicarbonate-Boron) and oils (Orange, Orange-Soybean and Orange-Olive) at doses of 2 g L-1 for salts and 10 ml L-1 for oils, with five replications, evaluated under a randomized complete block design. The variables evaluated were severity, phytotoxicity, number of fruits and yield. The results showed that treatments based on orange-orange and soybean-orange oils presented the lowest severity percentages, with 8.57% and 9.14%, respectively. The phytotoxicity variable showed no differences between treatments, as none caused toxicity in plants. Regarding the number of fruits and total yield, the orange-orange treatment had the highest averages, followed by the fungicide treatment. It is concluded that oil-based treatments may represent a viable alternative for managing P. xanthii, with the orange-orange combination at 10 ml L-1 standing out as an effective option in the Tehuacán Valley, Puebla, Mexico. |
