single volume. In 1933 the first volume of the sixth edition of the greatly ex- 

 panded work appeared. Hartig (1882) published his text on tree diseases. 

 Kirchner (1890), von Tubeuf (1895), and Frank (1896) wrote general texts. 

 Since 1900 many texts have been published, among the first being Duggar's 

 Fungous Diseases of Plants (1909). Some of the texts cover the general field, 

 while others are limited, dealing either with diseases of fruit trees, vegetables, 

 cereals, ornamental plants, or trees. 



One of the most important developments in the advancement of plant path- 

 ology and the control of plant diseases was the passage of legislation. Great 

 Britain (1877) passed its Destructive Insects and Pests Act against the Colo- 

 rado potato beetle and, in 1907, against all insect pests, the first ruling being 

 applied against American gooseberry mildew and the wart disease of potato. 

 The United States Department of Agriculture (1912) established a Federal 

 Horticultural Board and issued the Quarantine Act. The first orders were 

 against white pine blister rust and the wart disease of potato.
