Diversity of Micro Fungi on the Leaves of Hevea Brasiliensis

1 What is a pathogen? Carris, Little, and Stiles (2012) define pathogens as parasites causing disease and are classified according to their symptoms. It is known that 70% of plant diseases are caused by phytopathogenic fungi. Although phytopathogenic fungi are parasites, not all plant parasitic fungi are pathogens. Among the many types of fungi inhabiting plants, endogenous bacteria are closely related to plants and depend on them for nutrition. For biologically trophic fungal pathogens, they typically get nutrients from the living host tissue by specialized cells called vesicles formed in the host cells.

Introduction Natural rubber latex or generally abbreviated as NRL is a milky white liquid that was originally separated from the South American rubber tree (Hevea brasiliensis). It has a rubber content of 33% and is suspended in 65% water and contains 2% protein. NRL is chemically known as 1,4-cis-polyisoprene. To produce mainly gloves, NRL production is growing rapidly. Introduction Cassia auriculata L. (CA) is widely used in nutrition, astringency, anti-diabetes, conjunctivitis and ophthalmology in Ayurveda medicine (Subhadradevi et al., 2011). This is one of the major ingredients of Avaarai panchaga chooranam, Ayurveda's prescription for treatment of diabetes and management of blood glucose levels (Berman et al., 2001).

Latex is a viscose protective secretion that protects plants from herbivores. Many trees produce it when they are hurt, but the main source of latex used to make natural rubber is Hevea brasiliensis. Natural rubber was originally used for manufacturing resilient balls and waterproof sheets, but now it is mainly used for tires with low durability of synthetic materials. The latex which oozes out from the Balata tree (Manilkara bidentata) is used to make golf balls similar to rubber made from latex of paraquium of "getah perca" tree. It is also used as an insulator especially for submarine cables, dentistry, canes and buttocks. At present it is basically replaced by synthetic material
