Biorational strategies for the management of Meloidogyne enterolobii and Rotylenchulus reniformis in tomato, chili pepper, and cucumber production systems in Sinaloa, Mexico.

Abstract

In this document, we will address the current impact of root-knot and/or lesion nematode populations on tomato, bell pepper, and cucumber crops in the vegetable-producing areas of Sinaloa. We will address the magnitude of the direct and indirect damage they cause to the roots of the plants mentioned. We will also share our experiences in managing these plant parasites to eradicate or minimize populations in the soil through the use of biorational tools with a much more environmentally friendly approach, aimed at establishing healthier soil, promoting or improving the beneficial soil food web, and introducing biological control agents such as botanical extracts based on various secondary metabolites from products as cinnamon, mustard, epazote, neem, cassava, papalo, among others. Current limitations in the use of conventional nematicides, such as chemical fumigants and non-fumigants, favor the adoption of non-chemical strategies, such as biological control, with greater emphasis on reducing nematode populations and maintaining and increasing beneficial microbial diversity in the soil, in addition to the incorporation of composts, tea and compost leachate, thus im-proving soil and plant health. These approaches will be described and discussed, with special emphasis on integrated management.
