Available in PDF, EPUB and Kindle. Book excerpt: The Subject Of Plant Viruses And Virus Diseases Are Receiving Increasing Attention At The Hands Of Research Scholars Such As Chemists, Crystallographers, Entomologists, Geneticists, Serologists, Physicists Etc. They Are Able To Bring Fresh Techniques To The Subject. The Book Is An Attempt To Describe And Correlate The Advances That Have Been Made So Far In The Study Of Plant Viruses, And Virus Diseases. During The Past Few Years, Many New Virus Diseases Have Been Described, Some Of Great Economic Importance And Some With Novel Kinds Of Symptoms; Much Has Been Done On The Factors That Affect Spread; And Insect Vectors Have Been Identified In Species Of Insects Previously Not Incriminated. More Viruses Have Been Purified And Their Chemical Constitution Has Been Further Elucidated, And The Advances In Electron Microscopy Have Provided Much Information On Their Morphology. All These Developments Have Been Incorporated In The Book. The Book Is A Treasure For Agriculture And Horticulture Departments And All Those Interested In These Subjects.
