Item Evaluación del efecto de dos productos orgánicos, para el control de trips (Franklinella occidentalis) en el cultivo de fresa (Fragaria ananassa) variedad Albión(2022-03) Sulqui Jordán, Ronald Esteban; Zurita Vásquez, José HernánThe 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).Item Evaluación de tres patrones con resistencia a nematodos en tomate riñón (Solanum lycopersicum) Var. Eterei(2022-03) Andrade Llambo, Bryan Daniel; Curay Quispe, Segundo EuclidesThe present research work was carried out with the objective of evaluating three patterns: Olimpo, Monarca and Briomino to resistance to nematodes for the kidney tomato crop (Solanum lycopersicum L.), the same that was carried out in the Chiquicha parish, Pelileo canton, Tungurahua province, Located at an altitude of 2400 meters above sea level, with geographic coordinates of 1 ° 16 '0 "S South Latitude and 78 ° 31' 60" W West Longitude. The present research work was arranged in a randomized block design (DBA), with a factorial arrangement of 3 + 1 with four repetitions. The data were subjected to an analysis of variance (ANOVA) and then the data were examined using the 5% Tukey significance tests. In order to acquire the information, the Analysis of Variance (ANOVA) was used, with comparison tests of Tukey's mean at 5%, and using the statistical program Infostat. For the number of nematodes, the treatment P3 (Briomino Pattern) is located in the first place with an average of 48 nematodes in 20 ml of sample, located in the range A. The same treatment stands out for plant height in centimeters, being located in the First place with an average of 191 centimeters in height, ranking in rank A. The same pattern stands out in stem diameter in centimeters, ranking first with an average of 2.72 centimeters in diameter, occupying rank A. On the other hand On the other hand, for the number of fruits, P1 (Olimpo Pattern) is located in the first place with an average of 4.03 fruits, occupying the rank A, it also occurs in fruit weight with an average of 654.23 grams of fruit weight. Finally, for the root volume variable, P3 (Briomino Pattern) stands out again, placing it in range A with a mean of 90.13 ml. In conclusion, the best pattern for nematode control is P3 (Briomino Pattern), but the use of P1 (Olympus Pattern) is recommended, since nematode control is also outstanding, but mainly because the productivity values of tomato are better than the other patterns discussed
