Mechanisms of white mustard seed (Sinapis alba L.) volatile oils as transdermal penetration enhancers

Adult tarnished plant bugs (Lygus lineolaris) fed 5–10 times less frequently on seeds within pods of white mustard (Sinapis alba L.) than on seeds within pods of canola (Barssica napus L.) in no-choice feeding tests in the laboratory. The presence of long, sharp spines (trichomes) on pods of S. alba did not account for all of the difference in feeding on this mustard and on the smooth pods of canola because the feeding rate on shaved pods of S. alba was only twofold higher than on unshaved controls. Lygus lineolaris fed four times less frequently on seeds within pods of a commercial cultivar than on seeds of a near-isogenic low-glucosinolate line of S. alba, suggesting that it is the high concentration of the glucosinolate "sinalbin" in seeds that largely determines the low rate of feeding of L. lineolaris on this species.Plant breeders are currently developing low-glucosinolate lines of mustards such as S. alba for the oilseed market. Seed damage by L. lineolaris in an oilseed S. alba likely will be considerably higher than currently occurs in the mustard S. alba.

Weed Infestation

Dense white mustard (Sinapis alba L.) can suppress weeds, however excessive density negatively influences crop yields. The search for the optimal parameters for applying mineral fertilizers and the consumption of seed material will increase the crop yield and will improve its competitive ability. This work aimed to identify the seeding rate and doses of nitrogen fertilization at which white mustard plants can actively suppress weeds without reducing the productivity of the crop. In the course of this research, we established that S. alba sown at a rate of 2, 2.5 and 3 million seeds per ha suppressed the growth and development of weeds as much as possible. On average, in 2017-2019, the dry weight of weeds in the aforementioned variants was the least and reached 57.9; 42.3 and 38.4 g/m2, respectively. Weed species composition and quantitative parameters of weed infestation depended on the weather conditions of the year. The application of nitrogen fertilizer did not affect significantly the weediness of S. alba crops. The optimal density white mustard plant formed at a seeding rate of 2 million units/ha and, on average, for three years of research, the seed yield in this variant was the highest (0.6 t/ha).
