II — Celery Disease Control Demonstration. 

 Object : 



(A) To demonstrate the advantage of, 



(1) of seed bed rotation and sanitation in field and green- 



honse. 



(2) of seed treatment. 



(3) of spraying to control leaf diseases. 



(4) planting resistant varieties on soils infested with the 



celery stunt organism. 

 (e5) of exclusion of plants from diseased or suspected local- 

 ities. 



(B) To carr}^ on an educational campaign with growers to 

 familiarize them Avith the points of the above outline in order 

 to make permanent advance and lead to the completion of the 

 l)roject. 



(C) To improve marketing conditions in so far as they concern 

 celery diseases by, 



(1) imi^rovement and standardization of an open crate of 



uniform size and pack. 



(2) improvement of sliipping conditions in order that crates 



of celery will not be rotted on arrival at market. 



(3) assisting in the marketing of resistant varieties of good 



quality. 



This project is a natural outgrowth of the experimental 

 and demonstration work done on celery diseases the last two 

 years. The field work already done has largely been in the 

 hands of Mr. Ezra Levin and such advance as has been made 

 is to his credit. Last year was a year when celery blight 

 threatened to be serious. Mr. Levin who Avas working on a 

 summer appointment for this work Avas able to predict that 

 an epidemic Avas threatening and was able to induce the ma- 

 jority of groAvers seen to spray. In one month he secured the 

 sale of more than 150 sprayers. A visit to the groAvers to Avhom 

 this extension Avork has been carried shoAvs that permanent 

 results in the AA^ay of improving cultural j^ractices haA^e been 

 obtained. 



The "Easy Blanching," a green celery Avhich is largely im- 

 mune from the stunting disease, is being substituted for the 

 "Golden Self-Blanching" celery at Kalamazoo. The use of 

 this variety for "sick" soil is being widely advocated and as- 

 sistance in marketing will be given. 



Ill — Demonstrations and extension service in the elimination of 

 losses due to transportational diseases. 

 Object : 



1. To demonstrate the importance of careful grading, packing 

 and elimination of diseased fruits and vegetables in carload 

 shipments. 



2. To teach at the car door proper methods of handling i>erish- 

 ables as to pack, type of containers, sorting of stock, etc., in 

 order to avoid loss from disease in transit. 



3. To teach, basing the Avork on the needs as shown by car- 

 load inspection, proper methods of orchard and field control
