Study of the interaction mechanism between Heterodera schachtii and Rhizoctonia solani using a split-pot design on sugar beet

Abstract

Study of the interaction mechanism between Heterodera schachtii and Rhizoctonia solani using a split-pot design on sugar beet Estudio del mecanismo de interacción entre Heterodera schachtii y Rhizoctonia solani mediante el estudio de la disociación radical en remolacha azucarera ABSTRACTSugar beet plants were split into two pots to investigate in detail the interactions between Heterodera schachtii and Rhizoctonia solani and to determine if a relationship exists between the two pathogens. Additionally, hyperspectral leaf reflectance measurements were taken to detect symptoms caused by soil-borne pathogens. The results indicate a direct interaction between the nematode and the fungus. Treatments with both organisms together presented the most severe plant damage. By using leaf reflectance and calculation of the vegetation index, it was possible to establish differences between the treatments. This is a promising result for further studies, which will be useful for the detection and discrimination of symptoms caused by plant pathogens.
