Evaluation of the Effectiveness of the Use of Biopreparations as Seed Dressings

Abstract

In laboratory tests, the effectiveness of water plant extracts obtained from 20 species of herbal plants on the degree of contamination of white mustard seeds (Sinapis alba L.) by fungal and bacterial pathogens was evaluated. The analysis showed that the contamination of the tested seed material was statistically significantly influenced by the plant species from which the biopreparations were obtained. However, there were no significant differences in the method of preparation of extracts for the examined traits. The tested natural preparations had a different effect on limiting the superficial growth of bacteria and fungi on seeds. However, infusion and macerate obtained from the bark of Salix alba L. were the most effective in limiting the contamination with both bacterial and fungal pathogens. The number of seeds infected with fungi after the application of these preparations was 24.25% on average, whereas in the case of bacterial colonization of the tested material, the value of this indicator was 1.00% on average.

Evaluation of the Effects of Allelopathic Aqueous Plant Extracts, as Potential Preparations for Seed Dressing, on the Modulation of Cauliflower Seed Germination

“…The secondary metabolites exhibiting allelopathic potential, referred to as allelochemicals, have been a focus of interest for many researchers over recent years [8][9][10][11]. Equally great attention has been paid to the phenomenon of allelopathy, since evidence has been found for its significant role in regulating the growth of plants and the development of agricultural systems, including the quality and size of the crop yield produced [1,2,[12][13][14].…”

Identification of a Biostimulating Potential of an Organic Biomaterial Based on the Botanical Extract from Arctium lappa L. Roots

“…Nevertheless, some reports have demonstrated plant stimulation by other plants, as corroborated in previous research conducted by our research group. Extracts from allelopathic plants have been shown to improve the germination and development of seedlings of many crops [ 6 , 7 , 8 , 9 , 10 ]. In addition, when used via foliar or soil application, plant extracts have also affected the seeds yield of soybeans and biometric traits (plant height, location height of the first pod, 1000 seeds weight, and number of pods) [ 10 , 11 ].…”

Uncovering the Multi-level Response of Glycine Max L. To the Application of Allelopathic Biostimulant From Levisticum Officinale Koch

“…In addition, initiatives should be undertaken to obtain such forms of preparations and methods of their application that would promote plant growth and crop yield, taking into account mechanisms of their action and their biochemical composition. This may be the right direction in the long run, and following this direction will allow achieving sustainable development of agriculture, environmental and food safety, as well as the important economic stability for farmers [11][12][13][14][15][16].…”
