This study was conducted to evaluate the effect of insecticides on control of Spodoptera exigua, growth characteristics, and dry root yield in the cultivation of Alisma plantago after early maturing rice cropping. All pesticides treated had no effect on growth and flowering rate of Alisma plantago. The major insecticides were teflubenzuron Wp, 5%, tebufenozide Wp, 8%, iufenuron Ec, 5%, and tebufenozide Wp, 5%. Dry root yield were increased largely with tebufenozide Wp, 5%(20 g/20 l), insecticide than the other insecticides and no control. All insecticides had no injury with standard dosage. On the other hand, all insecticides had slight injury in the double dosage level for the Alisma plantago.

This study was conducted to evaluate the control effect of fungicides on control of brown leaf blight, growth characteristics, and dry root yield in the cultivation of Alisma plantago after early maturing rice cropping. All fungicides treated had no effect on the growth and flowering rate of Alisma plantago. The major fungicides were mancozeb Wp, 75%, chlorothalonil Wp, 75%, dithianon Wp, 43%, difenoconazole Wp, 10%, benomyl Wp, 50%, and propineb Wp, 70%. Dry root of yield were increased largely with chlorothalonil Wp, 75%(33 g/20), fungicide than the other fungicides and control. All fungicides had no injury with standard dosage. On the other hand all fungicides had slight injury in the double dosage level for the Alisma plantago.

Korean folk medicine 'Jil-Kyung-Ee' has been used to cure female disease, acute gastritis, edema, abdominal pain and pleurisy. The botanical origin of the crude drug has not been confirmed pharmocognostically. To clarify the botanical origin of 'Jil-Kyung-Ee', the morphological and anatomical characteristics of the leaves and roots of Plantago species growing in Korea, i.e. P. asiatica L., P. camtschatica Cham., P. depressa Willd., P. lanceolata L., P. major L. var. japonica (Fr. et Sav.) Miyabe were compared. As a result, it was determined that 'Jil-Kyung-Ee' was the whole plant body of Plantago asiatica and Plantago camtschatica.

The purpose of this study was to evaluate the effect of pesticides on insect pest control of Rhophalosiphum nymphaeae, growth characteristies and dry root yield from the cultivated after early maturing rice cropping. All pesticides treated had no effect on the growh period, flowering rate of Alisma plantago. The major pesticides were methomyl-Lf, 24.1 %, imidacloprid-Wp, 10%, carbosulfan-Wp, 20%, and methomyl-Wp, 45%. Dry yield of root were increased largely with imidacloprid-Wp, 10% (10g/20$\ell$), pesticide than the other pesticides and control. All pesticides were had no injury with recommended concentration. On the other hand all pesticides were slightly harmful in the double dosage level for the Alisma plantago.

Objective: Adriamycin (ADR) is an important anti-cancer drug which can cause renal toxicity. Given the known anti-inflammatory and antioxidant effects of Plantago major (P. major), the aim of this study was to determine the effects of hydroalcoholic extract of P. major on ADR- induced nephropathy in rats. Methods: Fifty male Wistar albino rats were randomly divided into 5 groups including: control, ADR (5 mg/kg), ADR + P. major (600 and 1200 mg/kg) and P. major (1200 mg/kg). The animals were treated with P. major extract for 5 consecutive weeks and ADR was intravenously injected on the 7th day of the study. Urine and serum samples were collected on days 0, 14, 21, 28, and 35 for the measurement of serum cholesterol and albumin levels and urine protein excretion rate. At the end of the study, the left kidneys were removed for apoptosis assessment. Results: Administration of ADR significantly decreased serum albumin level and increased serum cholesterol and urine protein excretion rate as well as, apoptotic cell numbers compared to the control group (P < 0.001) while had no effect on glomerular filtration rate (P > 0.05). Treatment with P. major, in both 600 and 1200 mg/kg doses, increased serum albumin level and decreased serum cholesterol concentration, urine protein excretion rate and as well as the number of apoptotic cell compared to the ADR group (P < 0.001). Conclusion: Our results showed that the P. major extract effectively protects against ADR- induced nephropathy by reducing kidney apoptosis and improving renal functioning in rats.

This study was conducted to evaluate the effect of seed disinfectant, in control of brown leaf blight, growth characteristics, and dry root yield in the cultivation of Alisma plantago after early maturing rice cropping. Experimental plot was laid out in split plots design with three replications. The major seed disinfectants were benomyl Wp, 20%, Captan Wp, 50%, Triferine Ec, 17%, Etridia zole Ec, 25%, and Thioplant-mythyl Wp, 50%. Even though seed disinfectant treated had no effect on the growth and flowering date of Alisma plantago, dry root yield was increased largely with benomyl Wp, 20%, in seed disinfectant than in the other seed disinfectants and contorl. All seed disinfectants had no injury with standard dosage. But all seed disinfectants had slight injury in the double dosage level for the Alisma plantago. On the basis of yield, vegetative and disease paramerer, benomyl Wp (20%) ($100g/20{\ell}$) had shown superior performance, however, all the seed disinfectants are effective as compare to without treatment.

To evaluate the protective effects of Plantago Major extract (PME) in stimulated BV-2 microglial cells and its anti-oxidant properties, cell viability assessment was performed by 3-(4, 5-dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. Lipopolysaccharide (LPS) was used to activate BV-2 microglia. Nitric oxide (NO) levels were measured using Griess assay. Tumor necrosis factor-alpha (TNF-${\alpha}$) production was evaluated by enzyme-linked immunosorbent assay (ELISA). Antioxidant properties were evaluated by 1, 1-diphenyl-2-picryl-hydrazyl (DPPH) radical scavenging assay. LPS-activated excessive release of NO in BV-2 cells was significantly inhibited by PME (P < 0.001 at $100{\mu}g/mL$). PME also scavenged DPPH radicals in a dose-dependent manner (P < 0.05 at $10{\mu}g/mL$ and P < 0.001 at $20{\sim}200{\mu}g/mL$). These results indicate that PME attenuated neuroinflammatory responses in LPS-activated BV-2 microglia by inhibiting excessive production of pro-inflammatory mediators such as NO and TNF-${\alpha}$. The anti-neuroinflammatory potential of PME may be related to its strong antioxidant properties.

The effects of topping method on the yield and major agronomic traits of two varieties, Sunwol and Youngjun of Alisma plantago, were investigated in the Southern region. Plant height, yield of fresh root, yield of dry root and weights of total roots were the highest in the variety of Sunwol, and at the plots with topping of four times cutting in flowering in main culm (Treatment No.1). Considering from our results, optimum topping method is most likly be topping of four times cutting in flowering in main culm in the Sunwol variety.

While rehmannia (Rehmannia glutinosa Libosch) was identified as a host of at least five viruses, including Rehmannia mosaic virus (ReMV), Youcai mosaic virus (YoMV), Broad bean wilt virus 2 (BBWV2), Plantago asiatica mosaic virus (PlAMV), and Rehmannia virus 1 (ReV1), viral incidence surveys have not been performed yet in rehmannia fields in Korea. In this study, we performed field surveys during 2017-2018 to investigate the incidence of 5 major viruses in rehmannia. A total of 145 symptomatic samples were collected from the rehmannia fields in major cultivation areas of Korea. Molecular diagnosis assays showed that all the collected leaf samples were infected with more than two viruses. Particularly, two species of Tobamovirus, ReMV and YoMV, were detected in all the samples. In addition, our analysis showed that the root stocks of 4 rehmannia cultivars were infected with at least two viruses. Since rehmannia is propagated by vegetative propagation, it is highly important to produce virus-free root stocks of rehmannia to control virus diseases in rehmannia.
