Impact of endophytic Trichoderma and Effective Microorganisms (EM) on damage to Kcona Kcona (EURYSACCA SP.) in quinoa (CHENOPODIUM QUINOA WILLD.) production.

The objective of the research is to determine the influence of strains of Trichoderma sp. endophyte and Effective Microorganisms (EM-1), in the incidence of “kcona kcona” (Eurysacca sp.), to establish the level of yield of the quinoa crop (Chenopodium quinoa Willd.) and profitability. Foliar applications of four strains were made at a concentration of (1x107cfu.ml-1), and a commercial product of Effective Microorganisms (EM-1), at a concentration of 5%, 10% and 15% respectively, in addition to a product chemical (Karate); during the phenological phases of: flowering, milky grain, pasty grain and physiological maturity. The lowest incidence was recorded in treatment T10 (Relative control: Chemical treatment - Karate) followed by treatment T6 (EM-1 10%), and the highest incidence of Eurysaca sp larvae. “Kcona Kcona”, was recorded in treatment T9 (Absolute control: no treatment), followed by treatment T3 (Trichoderma sp. Strain 3: UNA-TE-R-2); and the highest yield was obtained in treatment T6 (EM-1 10%) with an average of 3,871.70 kg/ha, followed by treatment T4 (Trichoderma sp. Strain 4: SG-TE-126) with a yield of 3,697.00 kg /ha; while the lowest yield was obtained in Treatment T9 (Absolute Control: No treatment) with 2,261 kg/ha, followed by Treatment T3 (Trichoderma sp. Strain 3: UNATE-R-2) with 2,262.87 kg/ha, respectively. In addition; The highest profitability was obtained in treatment T6 (EM–1 10%) with 535.22% profitability, followed by Treatment T4 (Trichoderma sp Strain 4: SG-TE-126) with 522.67%. The treatments with the lowest % profitability were Treatment T10 (Relative control: Chemical treatment - Karate) with 358.70%, treatments T9 (Absolute control: No treatment) and T3 (Trichoderma sp strains 3: UNA-TE-R-2) with 426.56% and 473.66%.
