Effect of Cabrio® Top and Macuco Bean (Pachyrhizus spp.) Extracts on Soil Mesofauna
Descrição
Abstract— Macuco bean (Pachyrhizus spp.) Is an atypical horticulture that has toxicity in its seeds and has
potential for disease control, but its effect on soil stability is unknown? Among the bioindicators to evaluate soil
quality is the analysis of fauna diversity, considered to be the most sensitive for presenting rapid response to
changes. Therefore, the objective of this study was to determine the effect that macuco bean extracts and
Cabrio® Top fungicide have on the soil mesofauna, with a completely randomized block design with three
treatments and six replications. The treatments were: bean extract (1: 1000), a solution of Cabrio® Top (1: 250)
and the water control. Pipes 100 mm in diameter were inserted into the soil 10 cm deep, one pipe being the
experimental unit. For the extraction of mesofauna the Berlese-Tullgren method was used. After eight days in the
extractor the samples with the mesofauna were removed for proper counting on the stereoscope. Moisture, group
richness and abundance of individuals were evaluated. The results showed that soil moisture favored the
richness of the edaphic mesofauna. Extract and Cabrio® Top compared to water increased the richness of
faunal groups, but water presented higher abundance of specimens. However, all evaluated variables did not
show significant variability between treatments. Therefore, Macuco bean extract and Cabrio® Top maintained
soil quality without imbalancing the edaphic mesofauna.
Keywords— Collemboli, Mites; Group wealth; Abundance of specimens.
