MANAGEMENT OF CORN CICADA WITH BIOINSUMOS A BASE OF FUNGUS (BEAUVERIA BASSIANA)

Resumen

Bioinsumos are governed by Federal Decree no. 10. 375 of May 26, 2020, which uses in its attributions, bioinsumption is considered the product, process or technology of plant, animal or microbial origin, intended for use in the production, storage and processing of agricultural products, in aquatic production systems or planted forests, which positively interfere in the growth, development and response mechanism of animals, plants, microorganisms and derived substances and that interact with products and physicochemical and biological processes. The bioinputs compatibility test was performed using the fungus Beauveria bassiana (Bals.) Vuill., strain PL63 (minimum of 1 x 108 viable conidia/ge and Isaria fumosorosea CEPA ESALQ-1296 (min. of 2.5 x 109 viable conidia/mL) at a dose of (500 gr/ha) associated with the insecticide based on Bifenthrin + Carbosulfan (600 mL/ha). In the field, the experiment was conducted in Sitio Santa Maria in the Municipality of Bandeirantes-PR located between the coordinates 50º37'63" WO and 23º15'79" S. Data collection was performed over a period of 4 months, with 1 crop in the management of corn culture. Soil analysis was performed (0 to 20 cm depth).  The work for the evaluation of the fungus and insecticide, being carried out in the field, when the plants presented in the phase V2, V4, V6.  The evaluations took place at 3, 7, 10, 14 days, after each application, total area considered (m2). The experimental design used was randomized blocks with 4 repetitions, with 15.75 m² plots (2.25 x 7) and spacing of 45 centimeters between rows, constituting 6 treatments, totaling 24 plots.
