A preliminary survey on the incidence and intensity of root disease complex (association of Meloidogyne incognita and root rot pathogens) was carried out in the sericultural areas of Karnataka. A total of 280 mulberry gardens were surveyed in 14 districts of Karnataka belonging to different types of soil (red sandy, red loamy and black cotton), farming systems (irrigated and rainfed), varieties (V-1, K-2, Local and S-13) and age of the plants (0-5, 5-10 and 10-15 years). It was observed that the association of M. incognita with Botryodiplodia theobromae and Fusarium solani causes the root disease complex in mulberry. Of the 280 gardens visited, 94 were infested with the disease complex and incidence was recorded as 33.6%. The higher intensity of root disease complex was observed when the root system had more than 100 galls/plant with infection of mixed population of B. theobromae and F. solani in sandy soil under irrigated farming. The 5-10 years old mulberry plantation with V-I variety was found to be most susceptible to root disease complex. Districts like Mysore, Kolar, Mandya, Tumkur, Chitradurga and Bangalore were observed as sensitive areas. Further, the wounds caused by M. incognita in mulberry roots favour the easy entry of root rot pathogens, which increased the severity of the disease very fast.

Mulberry Leaf (Morus-alba) is effective on reducing blood sugar increase and cholesterol in the blood. The objective of this study is to elucidate the sensory and physicochemical attributes of Mulberry Leaf Boogag with different amounts of glutinous rice paste and ginger juice. Mulberry Leaf Boogag, steamed for 90 seconds, was made by puffing the glutinous rice paste and ginger juice. The ratio of glutinous rice paste is made of a double, quintuple, and octuple proportion of water to the weight of the glutinous rice paste. The ratio of ginger juice is at a rate of one, three and five percent. According to the sensory evaluation, hardness and crispiness increased as the glutinous rice paste did, and ginger flavor, bitterness and sourness increased as the ginger juice did. Optimal conditions(p<0.05) were set when the value of hardness was more than five, and the value of bitterness and bitingness, lower than five. The optimal condition of Mulberry Leaf Boogag was established when the ratio of water to glutinous rice paste was 5.5, and in addition, 3.75 percent of ginger juice must be in proportion.

The results for the investigation of the various aromatic plants applied diets on silkworm raising from spring to autumn crops are found as followings. 1. There was no difference between the chemical menthol solution (1.0%) enriched diet and the normal diet for silkworm physiology. Neither injury nor advantage was obtained from the investigation. 2. It was found that there was no danger to use the mulberry leaves as silkworm diet by planting Mentha arvensis L. in the vacansy of mulberry farm, and no worse effect was found by rubbing the leaves of Mentha arvensis L. to the surface of mulberry leaves before feeding to silkworm. 3. For the investigation due to Perilla Ocymoides var application in stead of menthol plant ascribed in Paragraph (2) was obtained the same result. 4. As a conclusion of the study, the plantation of the both aromatical plants with mulberry trees is harmless for silkworm growing even though farmers worry about these to plant together with mulberry tree on mulberry farm.

Mulberry fruits were semi-dried using hot air ($60-100^{\circ}C$) or cool air ($20-40^{\circ}C$), and the effects of the drying temperature and processing time on the quality of the final dried mulberry fruits were investigated. Response surface methodology was employed to establish a statistical model and predict the conditions resulting in minimal loss of the total phenolic content (TPC) and ascorbic acid. Thus, using overlapped contour plots, the optimal conditions for producing semi-dried mulberry fruits, which reduced the moisture residue to 45% and minimized the nutrient losses of TPC and ascorbic acid, were determined for the hot-air process ($60.7^{\circ}C$ for 5.4 h) and cool-air process ($34.8^{\circ}C$ for 23.3 h). Plus, a higher drying temperature was found to lead to a faster loss of moisture and ascorbic acid, while the TPC was significantly decreased in the cool-air dried mulberry fruits due to the higher activity of polyphenol oxidase between 30 and $40^{\circ}C$.

Nowadays, the concern on the environmental load of bleaching process gave rise to the process of ECF(elemental chlorine free) and TCF(total clorine free). These sequences are based on oxygen-derived compounds such as oxygen, ozone, and hydrogen peroxide which is used as a typical eco-friendly bleaching agent. In this study, paper mulberry pulp was bleached with hydrogen peroxide and some bleaching process were accompanied with ultrasonication in order to increase the bleaching efficiency. The best bleaching efficiency of paper mulberry pulp was obtained in the condition of hydrogen peroxide and ultrasonication(20 kHz) bleaching system at $45^{\circ}C$ for 30 min. The brightness and kappa number of paper mulberry pulp were gained to 5.09% and 3.52 respectively. and yield was slightly loosed to 2%. Therefore, the efficiency of hydrogen peroxide and ultrasonication bleaching system of paper mulberry pulp was superior to the conventional hydrogen peroxide bleaching system. Magnesium sulfate acted as a bleaching stabilizer for the increasement of yield. As a result, the yield and viscosity were increased to 2.2% and 12% respectively.

Periodontitis is a chronic inflammatory disease that is known to have the characteristics of destructed periodontal tissue. Anti-oxidant and anti-inflammatory effects of mulberry leaves in periodontal tissue is not well known until now. We investigated the effects of n-butanol extract of mulberry leaves on the lipopolysaccharide (LPS)-induced proinflammatory cytokines, such as $IL-1{\beta}$, IL-6, IL-8 and modulates osteogenic differentiation in periodontal ligament cells. The expression levels of Runx2, ALP and mRNA were increased by n-butanol extract of mulberry leaves at the concentration of $100{\mu}g/ml$ in periodontal ligament cells. n-Butanol extract of mulberry leaves extract reduced the range of pathophysiological processes, such as inflammation and increase in the level of osteogenic-related genes. These findings suggest that n-butanol extract of mulberry leaves has therapeutic effects on periodontitis and periodontal tissue regeneartion.

A methanol extract of mulberry cake prepared from mulberry fruits (Morus spp.) was shown to have strong scavenging activities against DPPH, superoxide and hydroxyl radicals. Eleven phenolic compounds were isolated from the mulberry cake by a combination of Diaion HP-20, silica gel (or polyamide), Sephadex LH-20 column chromatographies, preparative HPLC and TLC. Their chemical structures were characterized as procatechuic acid (PCA), caffeic acid (CA), cyanidin 3-O-$\beta$-D-glucopyranoside (CyG) and cyanidin $3-O-\beta­D-rutinoside$ (CyR), rutin (RT), isoquercitrin (IQT), astragalin (AG), quercetin (QT), morin (MR), di-hydroquercetin (DHQ), and 4-prenylmoracin (PM) by spectral analysis and the published data. Most of the phenolic constituents were effective scavengers of DPPH, superoxide and hydroxyl radicals, and especially caffeic acid and 4-prenylmoracin showed potent superoxide and hydroxyl radical scavenging activity, in which their activities were higher than that of the well-known antioxidant, BHT (p< 0.05). Dehydroquercetin and quercetin also exhibited strong superoxide and hydroxyl radical scavenging activities. These results suggest that mulberry cake containing antioxidant phenolic compounds may be useful as natural antioxidants in functional foods and cosmetics.
