Chemical treatment of chickpea seeds and physiological and health impact

Abstract

The chickpea has been widely cultivated in agricultural fields in recent years, however, it is affected by a series of phytopathogens, which negatively affect the yield of cultivars. The objective of this study was to evaluate the physiological and health variables of seven chickpea cultivars and the efficiency of seed treatment for the control of phytopathogens. In the city of Urutaí, in the 2018 crop, cultivars BRS Aleppo, Flip 03, Flip 02, FLIP 155 C, 03 109, Cícero and Jamu 96 were cultivated and their seeds 120 days after planting were harvested and chemically treated (225 g L^-1) + Fipronil (250 g L^-1), with a volume equivalent to 200 mL of the pc per 100 kg of seeds) and plated using the Blotter Test Method (25 g L^-1) + methyl thiophanate. We used the completely randomized design, factorial scheme (seven cultivars x two presence of chemical seed treatment), with 10 replicates of 25 seeds per replicate. Fifty seeds of each cultivar (250 treated and 250 untreated) were analyzed, with primary root emission, shoot emission and incidence of microorganisms, incidence of microorganisms. A parametric, non-parametric and principal component analysis were used. The cultivars that presented the best performance were BRS Allepo, Flip 02 and Flip 03. Seed treatment favored the emission of aerial part and primary root emission. Seven fungi were identified in the seeds represented by Fusarium sp., Penicillium sp., Aspergillus sp., Rhizopus sp., Rhizoctonia sp., Mucor sp. and Cladosporium sp.
