Abstract
The aim of the experiment was to determine the effect of aqueous extracts of dried sage (Salvia officinalis L.) in concentrations of 2%, 5% and 10%, and the fresh parts of the plant in concentrations of 10%, 20% and 30% on the feeding of Sitona lineatus L. on the broad bean (Vicia faba L.) leaves. The olfactometry response of the pest (response to olfactory stimuli) was also determined in relation to the sage. Extracts of dry and fresh parts of sage reveal the inhibitory effect on feeding of both males and females of pea leaf weevil, the stronger, the higher their concentrations, however, no apparent differences were registered between the analysed sexes. Dry plant extracts in 10% concentrations and 30% extracts of fresh sage parts caused 2–3 time reduction of Sitona lineatus feeding after 4 days of the experiment. An apparent repellent response of aroma substances originating from sage towards weevil beetles (both males and females) was registered, which suggests potential applications of this plant as a neighbouring plant in mixed stands or, e.g., as a component of border belts.
Highlights
The use of natural plant protection products, for example plant extracts is one of the safest way to pest control or control of plant diseases and can be used in organic farming.The effective activity characterizes the extracts of herbal plants
The aim of the research was determining the effect of sage (Salvia officinalis L.) water extracts on feeding of pea leaf weevil (Sitona lineatus L.) males and females on broad bean (Vicia faba L.)
Observation of the rate of changes in broad bean leaf area losses due to female Sitona lineatus L. feeding from the beginning to the 60th hour of the experiment, for a majority of measurements demonstrated a significant effect of the individual sage extracts (Figure 1, Table 1)
Summary
The use of natural plant protection products, for example plant extracts is one of the safest way to pest control or control of plant diseases and can be used in organic farming.The effective activity characterizes the extracts (aqueous or alcoholic) of herbal plants. The extracts are different in the manner of preparing, a composition, concentration or kind of solvent Their applicability is very wide – from water extracts of dried or fresh parts of plant, applied as sprays or watering, to plant slurries. The main active component, in this case – sage oil reveals a strong antibacterial and fungicidal effect [Akhondzadeh et al 2003]. Active substances which it contains, such as: Journal of Ecological Engineering Vol 17(2), 2016 thujone, cineole, camphor, borneol, pinene and thiamine, a number of vitamins, including B1, C, PP, as well as resins, diterpene lactone, tannins, flavonoids or fumaric acid allow a wide-scale application of sage [Perry et al 1998]
