Evaluación de productos alternativos para la prevención de pudrición blanca (Sclerotium cepivorum) en la producción de ajo (Allium sativum L.) bajo cubierta en la granja Experimental Querochaca

Abstract

Garlic (Allium sativum L) in Ecuador is affected by phytosanitary problems and shortage of quality bulb seed, one of the main problems affecting the crop is the presence of white rot (Sclerotium cepivorum), it is for this reason and because of the high costs demanded for the control of this disease, the research was proposed with the objective of identifying the best alternative product for the prevention of this disease. This research was conducted at the Technical University of Ambato in the Faculty of Agricultural Sciences under cover in a soil free of this disease, within this research was used a completely randomized block design, all study variables were subject to analysis of variance and Tukey test at 5%, the variables studied were: plant height (cm), polar diameter (cm) equatorial diameter (cm), bulb weight (g), yield (T / ha), incidence and severity of the disease and days to harvest. Within all the variables studied, values ranging from 86.16 cm to 76.70 cm were observed in height at 30 days and at 60 days the values ranged from 94.04 to 82.24 cm, in terms of bulb weight, values between 50.86 and 33.33 g were obtained, in terms of yield we have values interpreted in T/ha ranging from 8.96 to 5.87 T/ha, taking into account these values, in most variables we have that P1F1 (oil ozonized every 8 days) was the best treatment in terms of yield, bulb weight and plant height. In relation to incidence and severity we can mention that the products evaluated acted effectively, since we have 0% in what refers to this variable. Key words: Allium sativum L, Sclerotium cepivorum, prevention, phytosanitary problems, product.
