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.

Highlights

White mustard (Sinapis alba L.) is a cruciferous plant grown in many parts of the world.Its importance in agricultural cultivation is steadily increasing due to its multidirectional use for seeds, as a postharvest crop and as a melliferous plant
It was stated that natural plant extracts can be used as inhibitors of fungal and bacterial pathogens, but these properties were largely determined by the plant species from which the biopreparations were obtained
The analysis of variance shows that the plant species from which plant extracts were obtained significantly influenced the colonization of seeds of Sinapis alba L. by fungal pathogens

Summary

Introduction

White mustard (Sinapis alba L.) is a cruciferous plant grown in many parts of the world.Its importance in agricultural cultivation is steadily increasing due to its multidirectional use for seeds, as a postharvest crop and as a melliferous plant. White mustard (Sinapis alba L.) is a cruciferous plant grown in many parts of the world. Sinapis alba L. cultivated after cereals as a catch crop plays the role of a phytosanitary plant, as it reduces the possibility of occurrence of pests and diseases of cereal plants. The agronomic value of white mustard lies in the seeds, which are currently used in food, pharmaceutical, cosmetic, chemical, and energy industries [3,4]. These seeds have a relatively low starch content and 25%–30% fat and 27%–35% protein with a very good amino acid composition
