V. Apply salt to single plants, to patches, or to whole fields 

 when badly infested. It should be applied dry, sown broadcast, 

 so as to reach all the leaves, at the rate of 18 pounds to the 

 square rod, a ton and a half to the acre. 



Remedy I is preventive and we regard it the best, not only for 

 this weed but as a settled policy for coping with all kinds of 

 weeds. When the plants are few they can be destroyed without 

 much loss of time, or expense. It is poor policy to wait until 

 fields are overrun and then be compelled to turn or salt them 

 at great expense. The safest way to fight a weed is not to 

 allow it to get a foothold. Our farmers should be on the alert 

 and when a strange plant appears in the fields it should claim 

 immediate attention, its name and habits should be determined, 

 and remedial measures at once adopted. 



In digging scattering plants of hawkweed it should be 

 remembered that they put out underground stems, and care 

 should be taken not to leave these in the ground to start new 

 plants. The fields should be examined later for any plants that 

 may have been overlooked, or start from stolons. 



The Orange Hawkweed in Maine grows along roadsides, in 

 orchards and in rocky pastures where it is undesirable, or 

 impossible to plow, and the only remedy available is to carefully 

 examine such places every year for scattering plants and thus 

 control the spread. If established, apply salt as suggested in 

 remedy V. 



Whether the King-Devil Weed will spread to pastures, we do 

 not know. In New York it grew along roadsides, and in 

 Maine the plant established itself in a mowing field that had not 

 been plowed for ten years. 



Method II recommends itself when there is no reason why 

 the field may not be turned and cultivated in a hoed crop. It 

 is a worthless method without clean culture and the exercise 

 of care that scattering plants on other parts of the farm are 

 destroyed and not allowed to mature and reseed the field. This 

 method was tried the past season on the University of Maine 

 farm for the Orange Hawkweed and was apparently successful. 



Professor L. R. Jones of the Vermont Experiment Station 

 has experimented largely with salt for the Orange Hawkweed 

 and claims that it will destroy it and prove beneficial to the
