  • Incidence of Powdery Mildew Disease
    INTERNATIONAL JOURNAL OF BIO-RESOURCE, ENVIRONMENT AND AGRICULTURAL SCIENCES (IJBEAS) Vol. 2(2) :281-286, 2016 www.sbear.in // ISSN 2454-3551 A REVIEW ON POWDERY MILDEW OF MULBERRY AND ITS MANAGEMENT S. Monir and N. C. Mandal Department of Plant Protection, Palli-Siksha Bhavana (Institute of Agriculture), Visva-Bharati, Sriniketan 731 236, West Bengal, India Received: April 2016 Revised accepted: May 2016 ABSTRACT Mulberry is the sole host plant of the silkworm Bombyx mori Linn which produces silk. The disease caused by fungus, Phyllactinia corylia makes mulberry leaves unsuitable to feed the silkworm. The Disease severity is ranging from a few individual spots to numerous lesions nearly covering entire leaves as a result there decrease in the production of quality leaves by 50% which greatly effects silkworm rearing as well as sericulture industry. With a view of adopting control measures, the incidence of powdery mildew were studied for eight different mulberry varieties namely Tr-10, S-1, S-146, S- 13, S-1635, AR-12, AR-14, Br-2 in autumn season. Key words: Mulberry, management, Phyllactinia corylia, Powdery mildew INTRODUCTION Powdery mildew of mulberry caused by Phyllactinia corylea (Pers.) Karst. was first reported from Ootacamund (Tamil Nadu) by Salmon as early as in 1905. The disease was later reported from all major mulberry growing areas in India. However, its incidence and intensity vary between geographical locations and seasons (Abbas et al., 2010, Chakravorty et al., 2003, Angwar and Thanavelu, 1991, Dikshit et al., 2006). The disease deteriorates the mulberry leaf quality by reducing the protein contents and moisture, and altering the various other leaf constituents (Chanturiya, 1968; Ali et al.,1987).

The designations employed and the presentation of the material in this publication do not imply the expression of any opinion whatsoever on the part of the Secretariat of the United Nations concerning the legal status of any country, territory, city or area, or of its authorities, or concerning the delimitation of its frontiers or boundaries. ii PREFACE It is well known that the Asian and Pacific region has an age-old tradition of producing and using silk, besides being the supplier of the commodity to the whole world. Recently, the silk trade, both within and outside the region, has become complex and competitive. To cope with this situation, there is a need to increase production as well as to improve the quality of silk. How­ ever, one of the most serious problems faced by many countries of the region in such efforts is the incidence of pests and diseases of both mulberry and silkworms. Indeed, cocoon and raw silk production, and ultimately the quality of silk produced, depend heavily on the success of silkworm rearing, and pests and diseases are an important factor affecting the productivity of silkworms. Thus, an effective means of increasing the production of silk and improving its quality is the control of such pests and diseases.

  • Ecofriendly Technologies for Disease and Pest Management in Mulberry-A Review
    IOSR Journal of Agriculture and Veterinary Science (IOSR-JAVS) e-ISSN: 2319-2380, p-ISSN: 2319-2372.Volume 7, Issue 2 Ver. II (Mar-Apr. 2014), PP 01-06 www.iosrjournals.org Ecofriendly Technologies for Disease and Pest Management in Mulberry-A Review N. Vijaya Kumari Dept.of Sericulture, S.P.M. University, Tirupati. Abstract: Mulberry belonging to the Genus Morus is extensively grown in South India where most of the sericulture industry is concentrated .Mulberry the main food sourse of silkworm Bombyx mori.L is a perennial plant. Since mulberry leaf is available throughout the year, it makes the plant prone to various diseases and pests. Various pathogens like fungi, bacteria,viruses and nematode cause diseases in mulberry. Among the pests few sap suckers and defoliators are considered to be major as they cause extensive damage to the mulberry. These diseases and pests cause around 12-25% leaf yield loss either by depletion in nutritive value or defoliation. Feeding these inferior quality leaf adversely affect the silkworm growth and finally the silk industry. To manage or control these diseases and pests a number of management strategies are followed which include physical, chemical and biological methods. Among these synthetic chemicals are commonly used and which are more effective , but continuous usage of chemicals cause environmental pollution resulting in adverse effects on soil flora,fauna and also human health due to residual toxicity. But many times the situation forces the farmer to depend on these synthetic chemicals which are not only costly but also unsafe on environment. So, there is a great need to think of environmentally safe methods for managing pests and diseases .

    Indian Phytopath. 66 (2) : 144-149 (2013) RESEARCH ARTICLE Evaluation of resistance mechanisms of mulberry cultivars through component analysis of aecial infection cycle of mulberry red rust (Aecidium mori) ANGELINA T. GONZALES1* and OSCAR S. OPINA2 1DMMMSU-Sericulture Research and Development Institute, Banotan, La Union, Philippines 2Plant Pathology Department, University of the Philippines-Los Banos, Laguna, Philippines ABSTRACT: Component analysis of resistance showed that the resistant reaction conferred by resistant cultivars was attributed to its ability to limit or suppress sporulation capacity, prolong latent period and shorten the infectious period of the fungus. The cohort life statistics revealed that the survival rate, proportion of infection units of Aecidium mori Barclay at various infection states and infection efficiency of mulberry red rust (MRR) did not vary significantly among resistant (Alfonso), moderately resistant (S-13 and SRDC-2) and susceptible (M-local, S-54, S-61 and Batac) mulberry cultivars. Regardless of cultivar, high mortality of infection units was recorded during the early stages of infection process. Sporulation capacity, infectious period and latent period of A. mori significantly differed among resistant, moderately resistant and susceptible cultivars. The infectious period of A. mori on susceptible cultivars was longer (20-32 days) compared to moderately resistant (12-28 days) and resistant (10 days) cultivars. A. mori produced abundant aeciospores in susceptible cultivars, few to less abundant in moderately resistant cultivars and very few in resistant cultivar. The latent period is longer in resistant cultivar compared with susceptible cultivars. The observed resistant reaction cv. Alfonso can be attributed to its ability to limit or suppress sporulation capacity, prolong latent period and shortened infectious period of the fungus.

  • Tropical Forages
    Tropical Forages Morus spp. Scientific name Morus alba L. Morus nigra L. Coppice regrowth, Cuba Leaves with serrate margins; syncarp red when immature, blackish purple, Morus rubra L. purple, or greenish white when mature Note: Most of the cultivated varieties are white mulberry (Morus alba L.), black mulberry (M. nigra L.), Indian mulberry (Morus australis Poir. syn. M. indica L.) and in North America, the American or red mulberry (M. rubra L.). Hybrid forms exist between Morus alba and M. rubra and others. Synonyms Coppiced plants growing with trees of Erythrina sp. in Costa Rica Morus alba L.: Morus alba f. tatarica Ser.; Morus alba Growing with mixed groundcover var. constantinopolitana Loudon; Morus alba var. multicaulis (Perr.) Loudon; Morus atropurpurea Roxb.; Morus multicaulis Perr. Note: No synonyms listed for M. nigra L. or M. rubra L. in GRIN. Family/tribe Family: Moraceae tribe: Moreae. Readily maintained at suitable level for High palatability makes it suitable for cut Morphological description browse and carry The common mulberry is a handsome deciduous tree, 10‒25 m tall, of rugged, picturesque appearance, forming a dense, spreading head of branches usually wider than the height of the tree, springing from a short, rough trunk. The form of the tree can vary from pyramidal to drooping. The simple, alternate, stipulate, petiolate, light green leaves are cordate at their base but very variable in form, even on the same tree; some are un-lobed while others may be almost palmate; margin coarsely serrate to crenate, apex acute, acuminate, or obtuse. Flowers are unisexual, borne in the axils of leaves or on spurs on separate spikes, or catkins, which are small, more or less cylindrical and trees may be monoecious or dioecious.
