Bioherbicida a partir de extracto fenólico obtenido de residuos de almazaras
The use of synthetic herbicides has been shown to have harmful effects on the environment and human health. An alternative to the use of these synthetic compounds is the development of pesticides derived from active principles, found in plants or secondary metabolites from microorganisms, which ha...

description |
The use of synthetic herbicides has been shown to have harmful effects on the environment and human
health. An alternative to the use of these synthetic compounds is the development of pesticides derived
from active principles, found in plants or secondary metabolites from microorganisms, which have
phytotoxic properties, but of little or no toxicity in mammals and that can be used in organic
agriculture. In this context, the present work analyzed the bioherbicidal capacity of a phenolic extract
obtained from olive mill wastewater, which is a liquid residue produced in the olive oil production. The
phytotoxic effect was evaluated through germination tests of wheat seeds (Triticum aestivum). The
effectiveness of the phenolic extract was compared with a commercial herbicide whose active
principle is Simazine. The results show that at concentrations of 100 ppm (gallic acid equivalents)
approximately 10% of the seeds germinate. Tests at concentrations of 480 and 1050 ppm inhibit all
stages of germination. Unlike the tests with the phenolic extract, the commercial herbicide does not
stop the radicular emergence in the seeds. However, they appear with deformations and fail to develop
normally. |
