take due precaution in preventing the spread from the orchards to his 

 nursery stock. Owners of such orchards were given orders to clean them 

 up and in most cases steps were taken at once to destroy infested trees 

 and shrubs. 



Due to the fact that 23 nurseries and a large number of orchards were 

 found infested with San Jose scale an educational campaign, as provided 

 for in the Nursery Inspection Law, was inaugurated in the fall of 1913. 

 Where a nursery was found infested with scale the nurseryman was re- 

 quired to destroy all infested plants including trees and shrubs and to treat 

 all stock subject to infestation with hydrocyanic-acid gas. 



Also scale-infested orchards were selected at Sikeston, Boonville, Wil- 

 lard, Pierce City, Jackson, Hannibal and Alexandria and during the fall of 

 1913 and early spring of 1914 spraying demonstrations were held at these 

 places for the control of the scale. In this work no effort was made to 

 spray large orchards in each locality but only a portion of an orchard. 

 Just enough spraying was done to show the fruit growers who were not 

 familiar with scale control just how it should be done. At these spraying 

 demonstrations, meetings were held at which methods of controlling in- 

 sects and diseases were described. Also the best methods of planting, 

 pruning, cultivating, selecting the site and other practical subjects of or- 

 chard management were given consideration. The results obtained from 

 these demonstrations were quite satisfactory and led to the purchase by 

 many fruit growers of sprayers and spraying material and the production 

 of cleaner and better fruit. The results of this work are given in detail in 

 Missouri Experiment Station Bulletin 132, "The Control of San Jose Scale 

 in Missouri." 



The results of the first year's work of nursery and orchard inspection 

 showed clearlv that a number of the nurserymen and many fruit growers 

 faced the problem of eradicating that most serious of nursery and orchard 

 pests, the San Jose scale, and also that the Plant Inspection Service had a 

 big task before it in heloine^ in this work of keeping Missouri orchards 

 free from injurious pests and diseases in the future. 



PLANT INSPECTION 1914-1915 



During the year 1914-15 the inspection work was done by Dr. Leonard 

 Haseman, Chief Inspector and Mr. T. J. Talbert, Deputy Inspector. A 

 total of 135 nurseries were inspected of which 113 were certified. The 

 acreage of nursery stock in Missouri in 1914-15 was 2551 located in 44 dif- 

 ferent counties. Five hundred and forty-nine cases of foreign stock re- 

 ceived in 13 different counties were inspected. These 549 cases contained 

 nearly 600,000 plants. One hundred and thirteen certificates of nursery in- 

 spection were issued; sixty-four dealers certificates, ninety-four growers 

 permits and 249 agents permits. 



Eleven more nurseries were inspected in 1914 than in 1913. These 

 nurseries existed in 1913 but due to the fact that 1913 was the first time that 

 a systematic inspection was ever attempted it was almost impossible to 

 locate every nursery in the State. These nurseries which were located and 

 inspected for the first time in 1914 were small ones and not widely known.
