An insufficiently studied and exploited direction today is the use of plant active principles in the agricultural area, in the field of weed and pest management of crops and seed in warehouses. Although conventional synthesis pesticides (chemical compounds) are showing satisfactory results, their repeated use leads to pest-resistant phenomena, which demands higher concentrations and increasingly complex compositions. The result is the temporary reduction of pest attacks, but variable amounts of related chemical compounds are found on treated plants or seeds, in agricultural soil and other adjacent crops, untreated with these substances. This ultimately results in the deterioration of the quality of the vegetal raw materials and even the animals for the food industry, respectively the deterioration of the quality of the foodstuffs with the health condition of the population. In order to avoid this aspect, in the concept of promoting an ecological and sustainable agriculture, vegetal extracts / volatile oils obtained from different plants were studied to prevent and treat the effects of pest and crop pest attacks on warehouses. Various biologically active compounds from plant sources have been shown to exhibit high efficacy, multiple mechanism of action, low toxicity to mammals, which has increased the interest in using them as biopesticides in a stabilized and easy to handle form. The aim of the herein reported investigation was to obtain some vegetal extracts using plants from spontaneous flora in the geographical area of Moldavia and Bucovina (Romania) for the production of non-toxic vegetal extracts, which show vermifug, repellent and / or germicidal effect on the field pests using two classical methods: heat reflux extraction and maceration.The obtained extracts were preliminarily characterized by sensory analysis, determination of physical constants and chemical compounds together with physical-chemical analysis by drawing and exhaustive interpretation of the UV-VIS and FTIR spectra. |
