Abstract
El trabajo de investigación se desarrolló en el distrito de Ccasancca - Caja - Acobamba - Huancavelica, el objetivo de investigación fue evaluar la influencia de las tres dosis de 100g/cil., 120g/cil., 140g/cil. del hongo (Metarhizium anisopliae) para control de Cogollero (Spodoptera frugiperda) en cultivo de maíz amiláceo (Zea maíz L). Metodología utilizada fue experimental en diseño de bloques completamente al azar desarrollado con cuatro tratamientos cuatro repeticiones, se evaluó el control de gusano cogollero del maíz (Spodoptera frugiperda), los resultados obtenidos fueron el porcentaje de incidencia del cogollero (Spodoptera frugiperda), presentando baja infestación en estas etapa fenológica de crecimiento en T1 = 60%, seguido etapa de crecimiento rápido T2=30% la etapa de floración demostrando una baja infestación con un 5 %, las dosis de T3= 140 g/Cilindro, se Observa esta dosis controla la incidencia de plaga en las etapas de crecimiento y floración llegando a alcanzar un 95 % de control eficaz del rendimiento del cultivo, seguido del T2 = 120 g/cilindro, se observa esta dosis controla la incidencia de plaga en etapas de crecimiento lento rápido llegando a alcanzar un 70 % de control, el T1 de 100g/cil, esta dosis controla la incidencia de plaga en etapa de crecimiento lento rápido llegando a alcanzar un 20%, seguido 15 % en etapa de floración indica que el tratamiento no controla a la plaga spodoptera frugiperda. Conclusiones, se debe utilizar el hongo (Metarhizium anisopliaea) en una dosis de 140 g/ Cilindro para controlar la infestación del cogollero en el cultivo de maíz.
The research work developed at Ccasancca - Huancavelica, the objective of investigation was to evaluate the influence of three dose of 100g linear integrated circuit - Acobamba Caja's district., 120g linear integrated circuit., 140g linear integrated circuit of the mushroom (Metarhizium anisopliae) for control of Cogollero (Spodoptera frugiperda) in cultivation of starchy corn (Zea corn L). Utilized methodology was experimental in design of blocks completely at random unrolled with four treatments four repetitions, himself I evaluate worm's control cogollero of corn ( Spodoptera frugiperda ), the obtained results were the cogollero's percentage of incidence ( Spodoptera frugiperda ), presenting low infestation in the stage fenológica of growth in T1 60 %, followed fast growth stage T2=30 % the stage of flowering demonstrating a low infestation with a 5 %, them T3's dose I Roll Flat 140 g, this dose is observed control the incidence of plague in the growth stages and flowering arriving to be enough one 95% of efficacious control of the performance of cultivation, followed I roll flat 120 g of the T2, this dose is observed control the incidence of plague in slow fast growth stages getting to linear integrated circuit to catch up with 70 % of control, the T1 of 100g, this dose controls the incidence of plague in slow fast growth stage arriving to catch up with a 20 %, followed 15 % in stage of Indian flowering that the treatment does not control to the plague spodoptera frugiperda conclusion, Cilindro to control the cogollero's infestation must utilize the mushroom ( Metarhizium anisopliaea ) in 140 g's dose himself inThe cultivation of corn.
