Evaluación del efecto de dos productos orgánicos, para el control de trips (Franklinella occidentalis) en el cultivo de fresa (Fragaria ananassa) variedad Albión

Abstract

The research was carried out to evaluate the effects of two organic products, for the control of thrips (Franklinella occidentalis) in the cultivation of strawberry (Fragaria ananassa) variety Albión, which was carried out on the property of Mr. Manuel Pérez, located in the Tungurahua province, Tisaleo canton, whose geographic coordinates are: 1 ° 21 ′ 0 ″ South latitude and 78 ° 40 ′ 0 ″ West longitude, with an altitude of 3 156 masl (GPS global positioning system). For the evaluation, a completely randomized block experiment (DBCA) was applied in which 3 repetitions of ten plants will be carried out each treatment (10 treatments and 1 control). The doses were D1 (1cc / L), D2 (2cc / L), D3 (4cc / L), D4 (8cc / L) and D5 (16cc / L). The extracts were E1 (garlic-chili) and E2 (garlic-chili + rotenone). The treatment with the best results was E2D4 (Garlic-chili extract + rotenone - 8 cc / L). Applying the 5% Tukey Test for number of trips per plant, it was located in range A with an average of 1.23 trips per plant; In reduction of the affected leaf area, it is located in the A range with 14.33% affectation. For the percentage of affected fruits, it is also located in rank A with 8.40% affectation. In fruit weight, this treatment also stood out, placing it in the A range with an average of 1.81 kg / plant. Finally, for crop yield it is located in rank A with an average of 12,439 kg / ha. In conclusion, it is recommended to apply the garlic-chili extract plus rotenone in a dose of 8cc / L of water to control the population of thrips (Franklinella occidentalis) in the strawberry crop (Fragaria ananassa).
