Mulberry (Morus alba L.) is an important economical crop plant in sericulture and it grows under a wide range of ecological condition. It holds a special place as a major foreign exchange earner for many tropical and temperate countries. India secures the second position for the production of raw silk in the world, which is short about 30% to fulfill the home requirements. The reasons for this deficiency as well as low quality of raw silk are, however, generally attributed to build up of the diseases of mulberry and silkworms, inadequate employment of improved culture and rearing practices. Right from sprouting and throughout growing seasons, it is largely affected by a number of pathogens like plant parasitic nematodes, fungus, bacteria, virus and insects causing various diseases forming disease-complex and break the host resistance. These pathogens are the main obstacles causing considerable loss in yield and nutritive value of mulberry foliage. Feeding of the diseased leaves affect the health of the silkworms adversely and the cocoon yield in terms of quality and quantity. Root-knot disease, caused by Meloidogyne incognita (Kofoid and White) Chitwood, reduces 10-12% leaf yield in addition to affecting the leaf quality for silkworms feeding. Leaf spots disease caused by Cercosporam moricola (Cooke) fungus, losses 10- 35% leaf yield reducing moisture, proteins adversely and ultimately the quality and quantity of cocoons. Phyllactinia corylea (Pers.) Karst fungus, causing powdery mildew disease, is the most common and wide spread economically important disease reducing 10-30% leaf yield and reducing the crude protein content by as much as 33%. The mosaic disease caused by mosaic virus results in inward curling of leaves, particularly leaf margins and tip with chlorotic lesions on the leaf surface, stunted growth and suppressed leaf size. Tukra disease, caused by Maconellicoccus hirsutus (Green) (Pseudococcidae), tremendously reduces the leaves, depleting the nutritive value and plant growth, leaf yield and leaf protein content significantly.
