Evaluación in vitro de aceites vegetales ozonizados en el control sigatoka negra mycosphaerella fijiensis (morelet).

Abstract

This study investigated mycelial growth in response to different treatments over a six-day period. Five control alternatives were evaluated, namely, Neem, Mancozeb, Girasol, Gobernadora and Palma. The variable of interest was mycelium growth, measured through percentage values. The results revealed significant variability in mycelial growth under the different treatments and over time. During the first day of measurement, notable differences between treatments were observed. Mancozeb and Sunflower showed a growth of 100%, while Neem and Palma presented lower values, with an average of 11,192 and 14,524, respectively. Governor was located at an intermediate point, with an average growth of 59,742%. However, as the days progressed, fluctuations in growth were observed. Mancozeb maintained a high growth rate on the second day, although it decreased slightly from the first day. Sunflower experienced a noticeable increase on the second day, but also decreased in the following days. Neem, Gobernadora and Palma showed a decrease in their growth as the study progressed. Importantly, the effects highlight the dominance of temporality in the dynamics of mycelial development. Growth values varied across days, indicating a dynamic response to treatments and possibly changing environmental conditions. Important information is provided on the variability in mycelial growth in response to different treatments and highlights the importance of consider temporality in research of this type. These findings may have implications for decision making related to the control of mycelial growth in agricultural or microbiological contexts.
