Nuevas estrategias de control de mosca blanca, vector de enfermedades virales en chile serrano en el centro y norte de México

Abstract

The objective of this work is to identify new control strategies for whiteflies, vector of viral diseases in pepper. The cultivation was sprayed twice a week in September and October. The yield of serrano chilli in a first cut goes from highest to lowest in treatments with: a- Flupyradifurone 150 g of i.a/ha (0.75 L/ha) in September and October, b- Flupyradifurone 150 g of i.a/ha (0.75 L/ha) in September and Super Magro+Sulfocalcic Broth 10 L of each/ha in October. The treatment c was Super Magro+Sulfocalcic Broth 10 L of each/ha in September and October and treatment d- Imidacloprid 87.5 g of i.a/ha (0.25 L/ha) in September and October. Results shown that Flupyradifurone tratment is an effective option to achieve high yields and minimize whitefly related damage, and the life of this product can extend, avoiding insect resistance, if its use is alternated with organic products. The Flupyradifurone treatment followed by the use of Super magro + mineralized Sulfocalcic Broth mixture reduces insecticide applications by 50 % and reduces the presence of whitefly populations that are capable of severely infecting chilli plants. Despite having plants with whitefly damage, when organic products are applied, they are capable of achieving high yields per hectare. As a conclussion, Imidacloprid can be substituted by Flupyradifurone or by Super Magro + mineralized Sulfocalcic Broth mixture. The 15 applications carried out in the months of September (7applications) and October (8 aplications), with Imidacloprid, can be changed for 15 organic applications, which would allow detoxification of the productive environment on the producing regions of pepper.
