Control of Macrophomina pseudophaseolina Crous, Sarr & Ndiaye with Trichoderma spp. and botanical and chemical pesticides

Resumen

Objective: The objective of the research was to evaluate in in vitro, greenhouse and field conditions, the effectiveness of biological, botanical and chemical pesticides for the control of Macrophomina pseudophaseolina.

Design/methodology/approach: In vitro, greenhouse and field experiments were carried out to evaluate the control effect of different pesticides for the control of M. pseudophaseolina.

Results: It was determined that all the evaluated strains of Trichoderma spp. they had a fungistatic effect against M. pseudophaseolina, and T. reesei showed the greatest antagonism and antibiosis against M. pseudophaseolina. High, medium and low doses of NeemAcar^® and high and medium doses of Regalia^® Maxx inhibited 100% the growth of M. pseudophaseolina mycelium. In the greenhouse, the lowest percentage of severity was obtained in the treatment with Regalia^® Maxx + T. reesei. In the field, the lowest severity was determined with the application of NeemAcar^® CE + Headline^®.

Limitations on study/implications: Our results are essential for the management of this disease by producers.

Findings/conclusions: The implementation of the use of Trichoderma spp., botanical pesticides and chemical insecticides is recommended for the control of M. pseudophaseolina,
