ARICOCHEA MUNOZ, Pablo et al. Adequate dose of the fungus (metarhizium anisopliae) to control farwood (spodoptera frugiperda) in corn production. Rev. Inv. Cs. Agro. y Vet. [online]. 2024, vol.8, n.23, pp.376-382.  Epub 02-Maio-2024. ISSN 2664-0902.  https://doi.org/10.33996/revistaalfa.v8i23.270.

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.
