"If You Have Choleba Upon Youb Fabm" 

 "DO" 



Notify your neighbors ttiat ttiey may protect themselves. 



Post notices of infection upon your gate posts to protect others. 



Notify the State Veterinarian that he may help you control the disease. 



Burn all dead carcasses and stop the spread of the disease. 



Disinfect, remove, and immunize all your well hogs. 



"DONT" 



Allow sick dogs to run at large; it is against the State laws. 



Don't allow strangers to go into your hog lots. 



Don't neglect to clean up your farm after an outbreak of cholera. 



Don't allow buzzards to hover over or alight upon your farm. 



Don't add new hogs to your herd without quarantining them for 30 days. 



Don't allow your hogs access to streams and overflows. 



And if we can have the help of every one to this extent, the losses from 

 hog cholera can be greatly cut down, and a final eradication of the disease 

 can be hoped for. 



Controlling of Crop Diseases. 



Hakry C. Young. 



It has always been exceedingly difficult to present the subject of plant dis- 

 eases to farmers. It is a proposition that must come to them from scientists, 

 must be handled by scientists through the cooperation with the crop growers. 

 A farmer is almost helpless before a serious attack of any plant disease and 

 as these diseases work on the plants in a similar manner that diseases work 

 on animals, it seems that his first duty is to consult or depend upon a 

 specialist to solve his problems. The state has in its employment men for 

 this work and all the crop growers need to do is to let their wants be 

 known. How many farmers through lack of knowledge of what plant dis- 

 eases are and how they work, lose a part or all of their crop which might 

 have been saved had the disease been recognized. The sooner farmers 

 realize that plant diseases exist and are increasing in number, the better 

 plant diseases will be controlled. In the majority of cases the son follows 

 out the ideas of his father. When we talk plant diseases to him he says: 

 "My father could raise good crops and fruit and never heard of plant dis- 

 eases, why should I spend time and money trying to eradicate something 

 that I scarcely believe exists." He forgets he is living in a different age 

 than that of his father. Diseases have become much more general in recent 

 years, especially since our modern methods of rapid transportation. Our 

 desire for new and imported varieties of seed helps to increase the spread of 

 plant disease. We can notice though that most of the farmers who are 

 making money today use every available means for crop protection. But the 

 sad fact is, the majority of the farmers of North Carolina are not making 

 enough money, the cause of which is largely due to the lack of dependence 

 in experts that are hired to help them, but instead clinging to the ideas of 

 their fathers. To give you some idea of how much the farmers depend upon 

 the specialists secured to help them I wish to cite the following example: In 

 many sections of the state the growers of leguminous crops have been notic- 

 ing a sort of damping off or wilt in some of their clover fields. This is 

 caused by a fungous disease that is brought into every community along 

 with the clover seed. The fungus forms its spores in small groups surrounded 

 by a heavy wall so that the small body of spores resembles very closely a 

 clover seed. These bodies are sown in the field along with the clover seed 

 and the result is you have introduced a disease that is likely to stay with 

 you as long as you try to grow clover. These little bodies known as sclerotia 

 can only be recognized by specialists. In order to check the present outbreak 

 the State Plant Pathologist sent out a request for every farmer to send in a
