Texas Physiology of Rust Resistance in "Wheat and Oats , (l) 



Make systematic study of organic compounds in wheat and oat 

 plants that may affect response of such plants to rust path- 

 ogens. Study (2) effects of fungicides, growth hormones and 

 related compounds that may modify host response to rust 

 organism; (3) physiology of pathogen to establish better 

 methods of distinguishing races or biotypes of organisms; 

 (U) interaction of environmental factors as light and temper- 

 ature on rust reactions and attempt to discover what compounds 

 are being produced or changed as a result of changes in en- 

 vironmental factors.

Utah Fluorosis in Plants and Animals . To learn (l) extent and 



distribution of fluorosis in plants and animals in selected 

 areas of Utah; (2) if increased levels of grain, Ca, and P, 

 and aluminum salts will help to alleviate symptoms of fluorosis 

 in dairy cattle; (3) if dairy cattle can be raised in areas 

 where fluorides are in atmosphere; (U) by survey on animals if 

 fluorosis in animals in increasing or decreasing; (5) toxic 

 level of fluorides for young dairy cattle; (6) by autopsies 

 and histopathological studies on animals with varying degrees 

 of fluorosis; (7) By survey if fluoride residue is decreasing 

 on plants in- Utah County.

Utah Insect Activity in Relation to Fluoride Content of Plants . 



(1) Survey areas of fluoride injury to plants for purpose of: 

 learning role of insects in injury of plants, studying insect 

 populations and species on plants injured by fluorine. (2) 

 By - greenhouse experiments learn if fluoride level of plant has 

 any direct effect on activity of insects associated with plant 

 under study.
