| Leaf spot disease is one of the most common fungal diseases that cause immense and sometimes irreparable damage to poplar trees. Therefore, in order to prevent the development of this fungal disease and to reduce its losses, identification and elimination of its pathogen (Septoria fungi) is very important. In this regard, conventional methods for detection of fungal contamination are time-consuming, costly and difficult. Therefore in this study, in order to distinguish healthy leaves from infected ones, as well as determining the rate of infection progress, a modified image processing algorithm by using the Laplacian threshold was used. Based on the results obtained in this study, the effect of illumination wavelength on the percentage of disease... |

| The Lambda Cyhalothrin is an insecticide of broad spectrum used in agriculture, to reduce the loss in crops, due to the attack of some pests. This compound has the presence of the radicals chlorine, fluorine and cyano, which can cause serious effects on human health when are ingested. Because of this, exist the need of develop non - destructive methods, capable of determining the concentration of the pesticide in farming, for eradicate the presence of this substance on the fruit used as food. To achieve this, commercial Lambda Cyhalothrin and distilled water were used, to obtain the recommended dilutions for the treatment of various pests in agriculture. The samples were analyzed through colorimetry, obtaining the characteristic color spaces for the... |
