Efecto de tres hongos benéficos y Azufre sobre insectos nocivos en el cultivo del frijol común (Phaseolus vulgaris L)

The present work was carried out in the "La Berta" farm located in the municipality of Alquizar, Artemisa province, with the objective of evaluating the effectiveness of the fungi Lecanicillium lecanii (Zimm) Zare & Gams, Trichoderma harzianum Rifai and Metarhizium anisopliae sensu lato ( Metsch) Sorokin at a dose of 10 12  conidia ha- 1 and Sulfur at a dose of 3 kg ha -1 (ai), applied weekly in the leaf area of the plant, in the control of thrips ( Thrips palmi Karny), leaves jumps ( Empoasca kraemeri Ross & Moore) and whitefly ( Bemisia tabaci Gennadius), in the cultivation of common bean ( Phaseolus vulgaris L.), variety CC-25-9N. A randomized block design with five treatments and four replications was used. The population of the insects was evaluated weekly, after the start of the applications, and a total of six evaluations were made. In addition, performance and some of its components were evaluated. All three fungi reduced insect populations compared to control, although the greatest effect was achieved with Metarhizium and L ecanicillium . The applications with fungi and sulfur also caused a positive effect on crop yield and its components.
