"With more exact correlation of

 growth and farm operations, and 

 the more efficient or economical 

 adaption of crops to soil and clim- 

 atic conditions. 



The Office of Dry Land Agricul- 

 ture of Bureau of Plant Industry 

 is studying influence of climate in 

 Crop Production at 14 Stations in 

 7 States froni Texas to North Da- 

 kota. This should extend to Mani- 

 toba, Saskatchewan and Alberta.

In the case of Wheat Rust some 



co-operative work has been done 

 already between Messrs. Stakman 

 at St. Paul and Eraser at Saskat- 

 oon. 



There remains, however, much to 

 be done, since this is a disease that 

 must be controlled in these count- 

 ries if we are to continue to grow 

 wheat. We need a study of the 

 Epidemiology of this disease. That 

 means co-operation from Texas to 

 Northern Saskatchewan. 

 It would be very advantageous for 

 farmers in the North to be early 

 advised of the probability of a 

 serious rust epidemic any given 

 season, as based on conditions in 

 the South where the rust starts 

 very early in the year, provided of 

 course, that conditions in the North 

 should prove to be favorable to rust 

 development. 



The same Biologic Specialization is 

 necessary to develop disease or rust 

 resistant strains. 



Further, Cultural Condition tests 

 are needed over wide areas to 

 study the influence of cultural 

 methods on rust. 



Then there is the question of Oat 

 Rust in the East. 

 The question of the possibility of 

 the destruction of the intermediate 

 host plants of the wheat rust, bar- 

 berry in the west, and of the oat 

 rust, buckthorn in the east, is sure- 

 ly worthy of careful consideration 

 in an international way. 

 In short, there is room and need 

 in the study of this great prob- 

 lem for the co-operation of all the 

 capable plant pathologists, plant 

 breeders, plant physiologists, bio- 

 chemists and agronomists in both 

 countries.
