Agricultural management of Amaranth and Quinua with Metarhizium anisopliae for the control of insects

Abstract

The experiment was conducted at the Pontificia Universidad Católica del Ecuador - Sede Ibarra (PUCE-SI), in the experimental farm, three doses of entomopathogenic Metarhizium anisopliae was evaluated for the control of worms that affect the initial development of crop quinoa (Chenopodium quinoa Willd) and amaranth (Amaranthus spp.) Design of randomized complete block design with three treatments and four replications for each crop was used. Within the specific management of the experiment, each experimental unit consisted of a plot of 5 m long, 2 meters wide , in which 4 spaced at 0 furrows were laid , 5 m, of which the central rows were evaluated and the remaining two were taken as the edge effect.The variables in this research were evaluated. The efficacy in the control of soil insects, indirectly measured using Abbot’s formula for the number of affected seedlings after application and at 10, 20 and 30 days after borning. They were evaluated as variables: a) Effectiveness application to 15,25 and 35 days after borning and b ) performance achieved at harvest. It was concluded that there is no difference in crop yield when the entomopathogenic fungus Metarhizium anisopliae for the control of soil insects used.The highest yield was achieved with the use of 340 g x ha- 1 entomotatógeno with a volume of grain 1520 kg x ha-1. For amaranth grain harvested was 1506.25 kg x ha-1, with the same dose of the fungus.
