Jedan od većih problema u poljoprivrednoj proizvodnji je kontrola različitih štetnika i bolesti koje mogu pričiniti značajne štete, i time smanjiti ili potpuno uništiti očekivani prinos poljoprivrednih kultura. Da bi se uspješno nosili sa ovim problemima poljoprivrednici koriste različite vrste pesticida. Zbog sve veće brige za zaštitu ljudi i okoliša, reducira se broj aktivnih tvari i ukidaju preparati, odnosno formuliraju se nove aktivne tvari koje su manje štetne za okoliš i korisnike. Stoga poljoprivrednici traže dodatne mogućnosti i rješenja u borbi protiv štetnika i bolesti. Odnedavno, na tržištu EU pojavili su se preparati koji su označeni kao osnovne tvari, koje se mogu koristiti kao dodatna rješenja u borbi protiv štetnika i bolesti. Zakonskom regulativom, kroz EZ Uredbom 1107/2009 na razini EU postavljen je kvalitetan okvir za sigurnu i učinkovitu primjenu osnovnih tvari u poljoprivrednoj proizvodnji. Dodatna prednost primjene većine navedenih osnovnih tvari je njihova sukladnost za primjenu u ekološkoj poljoprivrednoj proizvodnji. Iako postoji više od 20-tak različitih osnovnih tvari koje se koriste, u upotrebi su najčešće tekući ekstrakti koprive (Urtica spp. L.) i poljske preslice (Equisetum arvense L.), te hitozan hidroklorid, lecitn soje i natrij hidrogen karbonat.

Basic Substances

In the work presented herein, we analyze the efficacy of three basic substances that comply with European Regulation (EC) No 1107/2009, namely chitosan, horsetail (Equisetum arvense L.) and nettle (Urtica dioica L.), for the control of grapevine trunk diseases (GTDs) in organic farming. The E. arvense and U. dioica aqueous extracts, prepared according to SANCO/12386/2013 and SANTE/11809/2016, have been studied by gas chromatography–mass spectrometry (GC-MS), identifying their main active constituents. The three basic substances, either alone or in combination (forming conjugate complexes), have been tested in vitro against eight Botryosphaeriaceae species, and in vivo, in grafted plants artificially inoculated with Neofusicoccum parvum and Diplodia seriata. A clear synergistic behavior between chitosan and the two plant extracts has been observed in the mycelial growth inhibition tests (resulting in EC90 values as low as 208 μg·mL−1 for some of the isolates), and statistically significant differences have been found in terms of vascular necroses lengths between treated and non-treated plants, providing further evidence of aforementioned synergism in the case of D. seriata. The reported data supports the possibility of extending the applications of these three basic substances in Viticulture beyond the treatment of mildew.

Root Exposure

The absorption, translocation and exudation of 14C-labelled dichlobenil (2,6-dichlorobenzonitrile) and vernolate (S-propyl-dipropylthiocarbamate) in field horsetail (Equisetum arvense L.) were examined in glasshouse and laboratory experiments. When applied as a vapor, more dichlobenil was absorbed than vernolate, irrespective of whether the roots or shoots were exposed to the herbicide vapors. Neither herbicide was translocated to the shoots after root exposure to the 14C-vapor, but a small amount was translocated to the roots after shoot exposure. When applied in aqueous solution to the roots and rhizomes, more 14C was recovered from the rhizomes of plants treated with vernolate. Both herbicides were concentrated at the rhizome nodes. Small amounts of 14C (less than 0.5% of the applied activity) were found in the guttation fluid and in root exudates.

Abstract Equisetum arvense tea (TEA) contains high concentrations of silicon and has been used in folk medicine for the treatment of inflammatory ailments. We examined the resorption of silicon after TEA consumption. Safety and immunological effects were secondary outcomes. A monocentric, randomized, three-armed pilot study was conducted with 12 voluntary, healthy, male subjects. The study is registered in the German register for clinical trials (DRKS-ID: DRKS00016628). After a low silicon diet for 36 hours, 1000 mL TEA1 with approximately 200 000 µg silicon/L, TEA2 with approximately 750 000 µg silicon/L, or Si-low-Water (approximately 10 – 10 000 µg silicon/L as a control) were ingested on three consecutive days. Blood and urine samples were collected at baseline, day 1 examining silicon kinetics, day 3 examining silicon accumulation, and day 8 (safety, immunological parameters). Si-low-Water intake did not change silicon serum (Cmax 294 µg/L) or urine (19 000 µg/24 h) concentrations compared to baseline. Cmax was 2855 µg/L for TEA1 and 2498 µg/L for TEA2; tmax was 60 and 120 min, respectively. Silicon accumulation did not occur. Urine silica within 24 h (E24 h) was higher after TEA2 compared to TEA1 ingestion (142 000 vs. 109 000 µg/24 h). Serum silicon levels at t = 120 min differed significantly after intake of TEA2 or intake of Si-low-Water (p = 0.029). The immunological parameters did not show any significant changes indicating immunosuppressive effects in volunteers. TEA1 was well tolerated, while TEA2 caused diarrhoea in 4 subjects. Our investigations show that intake of TEA1 leads to significant rise in serum silicon concentration.
