“…Washing does not necessarily remove them either, so prevention is essential. Microbial biofungicides can be introduced in nutrient solutions through the nutrient film technique or applied in irrigation to prevent Pythium root (McGehee et al, 2019). It appears both in field crops and in protected spaces, under high humidity and temperatures ranging between 10 and 21 °C.…”

Lettuce microgreens are one of the most popular vegetables due to them being perceived as a “healthy food”, with high concentrations of nutrients, beneficial vitamins, and minerals. With a short vegetation period, they can be cultivated with minimum investment, and they are increasingly accepted by consumers, as they are healthy and easy to prepare. Lettuce has high ecological plasticity, but, despite this, its phenotypic expression, morphology, physiology, and anatomy are significantly influenced by environmental conditions. Lettuce microgreens contain higher quantities of phytonutrients and minerals and lower quantities of nitrates at the early stage of development than at the completely developed stage. The environmental conditions that influence the development of lettuce microgreens (and their quality) in a hydroponic system are as follows (average ideal values): light (400 W), photoperiodicity (12 h), light intensity (400 µmol m−2 s−1), colour spectrum (440-460 nm), temperature (20 ± 2 °C), and humidity (80 ± 5 %). The nutritional solution in a hydroponic system must be carefully monitored, by checking certain essential parameters such as the following (average ideal values): pH (6.3 ± 0.4), electrical conductivity (1.8 ± 0.2 mS), dissolved oxygen (6 mg L−1), and temperature (18 ± 2 °C). The analysis of expert literature reveals that there is a need to establish certain protocols for cultivating microgreens in hydroponic systems, to minimize the factors that can negatively influence the plants, in order to obtain higher concentrations of active substances.

“…Maar ook hier zijn de effecten nogal eens beperkt. Ook worden soms plantengroei remmende effecten waargenomen (McGehee et al, 2019). In de vollegrond zijn de omstandigheden voor biologische bestrijders lastiger: in tegenstelling tot substraat is het bodemleven in grond veel diverser en is het voedselweb complexer, waardoor de toegediende antagonisten het moeilijker zullen hebben om aan te slaan.…”

“…Plant diseases can be bacterial, which are most often manifested by putrefactive diseases, and viral, the evidence of which is the mosaic contour, depending on the source of infection. In addition to the above, diseases of non‐parasitic nature should be noted (McGehee et al, 2019). Through the nutrient solution during irrigation, the keel, black leg, white rot, gall nematode, streak, late blight, and other diseases can be transmitted.…”

To prevent the development of plant diseases, irrigation water needs to be disinfected. The commonly applied cleaning methods do not allow the possibility of activation and enrichment of irrigation water with nutrients. The target of this study is to develop an environmentally friendly method for disinfecting and activating irrigation water by treatment with high‐voltage discharges in an electro‐hydraulic installation. The study used the following materials and equipment: a high‐voltage installation with an electro‐hydraulic spark gap, an EnSURE luminometer (Hygiena) to measure the level of hygiene of water and its solutions, AquaSnap Total (AQ100X) test tubes (Hygiena) to determine the total amount of adenosine triphosphate (ATP) in water, and an ITAN ionomer (Tomanalit) for measuring nitrogen compounds in water. Experimentally the following optimal parameters and technological conditions were determined and substantiated to reduce irrigation water pollution from 1210 RLU to 73 RLU and increase water content of nitrogen compounds from 1.2 mg L‐1 to 8.4 mg L‐1: an operating voltage of 19.9 kV, a capacity 0.145 μF, and a number of discharges of 2860 pcs. Water disinfected with high‐voltage discharges will be useful for agricultural irrigation since it can serve as a nitrogen fertilizer, which does not have any harmful effect on the environment.
