The pest infestation not only reduces the production of mulberry leaf, but also affects quality of leaf and in turn that of cocoons. In order to minimize the chemical inputs and save environmental hazards, a number of eco-friendly control strategies have been evolved. However, for the adoption of any technology, it is foremost important that awareness and knowledge about the same is essential. Hence, a study was taken up in Shapur cluster (Kolar district) comprising of 15 villages so as to know the knowledge and perception of insect pests and their management practices. The results revealed that all most all the farmers were aware of uzi fly and pink mealybug and the damage caused by the same. Majority of the farmers had the knowledge of leaf roller, Bihar hairy caterpillar and grass hopper. With regard to knowledge of IPM, all the farmers were aware of IPM ofwz/fly, but IPM of mulberry pests was known to very few of them. With respect to using bio-control agent against uzi fly, majority of them expressed non-availability as the major constraint and expected them to supply the same to their door steps at free of cost whenever needed.

Mulberry is an economic tree being cultivated in China, India and several other Asian countries to feed the silkworm, Bombyx mori, as mulberry leaf is the only food material available for this insect. The recent burst in the industrialization and urbanization has considerably reduced the availability of land for agriculture purposes in these Asian countries. This, in turn, has added much pressure on many agro-based industries, including sericulture, to utilize the hitherto unutilized or marginally utilized areas for crop production. Sericulture, a rural agro-based industry, is attempting to expand mulberry cultivation to drought- and salinity-affected lands. Mulberry is only moderately tolerant to salinity and drought stresses, thus utilization of natural variations in stress tolerance does not hold much promise. Therefore, efforts are being taken to develop stress-tolerant varieties using modern biotechnological methods, including transgenesis. This paper provides an overview of the progress made to achieve this latter goal, highlighting the problems and prospects. Different methodologies used to achieve transgenic mulberry, their merits and demerits are also discussed. © 2011 Elsevier B.V.

Twelve short-listed bivoltine silkworm germplasm accessions of Central Sericultural Germplasm Resources Centre (CSGRC) Hosur, Tamil Nadu were evaluated for 16 post-cocoon parameters of qualitative and quantitative importance to identify the superiority of the silkworm germplasm accessions over ruling races viz., CSR-2 and CSR-4. The study revealed significant differences among the accessions for most of the parameters considered. Overall evaluation of germplasm accessions based on analysis of variance and Mano's trait evaluation index inferred that the accession BBE-187 was superior to CSR2 andCSR4 for fine denier and low evenness variation-I. The accession BBE-262 was found superior to CSR2 for fine denier, high neatness, low boil-off loss, low evenness variation-I, high tenacity and high elongation % and to CSR4 for fine denier, cleanness and low evenneis variation-I. The overall analysis of the data revealed that the germplasm accessions, BBE-187 and BBE-262 could be used as potential donor parents in breeding programmes for improving post-cocoon traits or to gain heterosis in cross breed development.

Fluorescent Pseudomonas and Bacillus arc considered to be the most promising group of Plant Growth Promoting Rhizobacteria (PGPR), which arc also involved in biocontrol of many plant diseases. In view of exploring potential of these microorganism! as mulberry growth promoters and disease control agents, effect of biopriming with nine strains ol fluorescent Pseudomonas (Pf-1 to Pf-9) and Bacillus subtilis (Bs) on the seed germination and seedling growth of mulberry was studied. Significantly (P<0.05] higher germination (99.02%) was found when the seeds were bioprimed with B. subtilis followed by Pseudomonas fluorescence (97.50%) strain Pf-9 and Pf-2. However, the vigour index was found higher (368.6) due to biopriming with Pf-4. Compared with control, the mean total length of the seedling was found higher (11.48%) when the seeds were bioprimed with strain Pf-2 in the in vitro germination study. Similarly, study using strile soil showed higher shoot length due to biopriming with Pf-2 and Bs. These strains showed increase in mean total length 12.58% and 3.89% respectively over the control. Antagonistic effect ol various plant growth promoting rhizobacteria to Rhizoctonia bataticola a root rot causing fungus showed significantly (P<0.05) less radial growth towards all the bacteria compared with the control (39.88 mm). The radial growth of R. bataticola was least in presence of Bs, Pf-2, Pf-4 and Pf-6 ( 11 -13 mm). The study suggests exploration of effective native antagonistic PGPR for mulberry growth as well as for root rot disease control.

In order to suppress soil borne pathogens from contaminated soils to raise disease free mulberry plantation, studies were conducted in plots infested with pathogens causing nursery |Stem-canker (Botryodiplodiu theobromae), cutting rot (Fusarium solani), collar rot (Phoma sp.) and die-back (B. theobromae)\, root rot (Fusarium solani, F. oxysporum, B.theobromae, Macrophomina phaseolina) and root knot (Meloidogyne Incognita) diseases. Different treatments such as deep digging, soil solarization, application of neem oil cake and growing of Dhaincha (Sesbania aculeata) crop alone and their combinations were imposed. Population of pathogens was assessed at 10 days interval up to 80 days after imposing treatments. Complete suppression of population of all the pathogens was observed after 80 days in the combined treatment where deep digging (30 cm), application of neem oil cake (@ 800 kg/ha after 45 days) and raising & mulching of Dhaincha (@ 20 kg seeds/ ha 6 days after neem oil cake application) crop was done. When the new plantation was raised after 80 days of imposing the treatment, all the plants were survived and found free from soilborne diseases besides increasing plant height (32%) and leaf yield (35.0%) over untreated control.

CSRTI, Mysore, India, focused on the technologies, such as plantation techniques, inter-cultural operations, irrigation, techniques, inter-cultural operations, and irrigation besides developing promising mulberry varieties. These efforts supplemented nutritive elements in the soil through fertilizers, manures and organic inputs, and came out with integrated farming system. The technology introduced by the institute included variety, spacing, irrigation, pruning and training, intercultural operations, and manure and fertilizer applications. Land use and cultivation practices which are recommended in relation to climate had played a major role in improving mulberry leaf production per unit area. A good drainage system was also important to drain the excess water from mulberry plantations to produce better quality varieties for different applications.
