| Spanish abstract | La enfermedad más peligrosa que afecta al cultivo de agave en Oaxaca, México, es la pudrición blanda del cogollo, conocida como mancha bacterial, causada por la bacteria Pectobacterium carotovorum subsp. carotovorum (Jones, 1901). Se determinó un método de control de la bacteria mediante agroquímicos, así como de su hospedante y los vectores de la misma. Se evaluó el efecto de la bacteria sobre hongos y nematodos entomopatógenos, los cuales son empleados en el control de larvas y adultos del picudo de agave. El Agrimicín y el azufre controlaron e inhibieron colonias de la bacteria con más del 90 % en ambos casos. Se encontró que el suelo no es un agente causal que trasmite, o sea un hospedante de la bacteria; los insectos son vectores y las hojas de agave son hospedantes de Pectobacterium carotovorum. La bacteria no afectó a las poblaciones de hongos y nematodos entomopatógenos |
| English abstract | The most dangerous sickness that affects the agave in Oaxaca, Mexico is the putrefaction of the bacterial spot which is caused by the Pectobacterium carotovorum subsp. carotovorum (Jones, 1901). It has been determined a controlling method for the bacteria a based on some agrochemicals as well as the vector and shelterers. It was evaluated the effect of the bacteria on fungi and nematodes entomopathogenic, which were employed for controlling the larvae and the mature of agave weevil. The Agrimicin and sulfurcoul control and stop the colonies of the bacteria in a 90 % in both cases. It was also found that; the soil is not a factual agent that transmits or shelters the bacteria, that the insects are vector and that the agave leaves are shelters of the bacteria, did not affect the colonies of fungi and entomophathogenic nematodes |
