PLANT INSPECTION IN MISSOURI 9 



and unless it is thoroughly cleaned up will serve as a source of infesta- 

 tion for an entire community and in the long run may cause a loss of thou- 

 sands of dollars. In case an infested orchard was found near a nursery, 

 additional emphasis was placed upon the necessity of cleaning up the prem- 

 ises. It is gratifying to state that in practically every case the fruit grow- 

 ers were more than willing to cooperate with the Plant Inspection Service 

 in every way in order to get rid of dangerous pests and diseases. 

 That most dangerous of orchard pests, the San Jose scale, is 

 widely distributed over Missouri and the Plant Inspection Service has a 

 gigantic task before it in cleaning up and preventing a further spread 

 of this pest. A task which will require both a great deal of time and a 

 great deal of money, but which in the end will amount to very little as 

 compared to the returns which can be obtained from a clean and healthy 

 orchard. 



The results of the inspection work in 1915-16 showed very conclusively 

 that the Missouri Plant Inspection Service was rendering a great service 

 to the nurserymen and fruit growers of the State by locating and helping 

 clean up infestations of dangerous insect pests and diseases. 



PLANT INSPECTION 1916-17 



During the year of 1916-17 the nursery inspection work was carried on 

 by Dr. Leonard Haseman, chief inspector and C. V. Vinson and K. C. 

 Sullivan, deputies. The work was conducted in the same manner as the 

 year before, except very little orchard inspection work was done due to in- 

 sufficient funds necessary for carrying on such work. 



One hundred thirty nurseries were inspected located in forty-seven 

 different counties of which 107 were certified. The total acreage of nursery 

 stock growing in Missouri in 1916-17 was 2,860. Three hundred eighty- 

 nine cases of imported stock containing 570,766 plants were inspected in 

 eleven different counties. One hundred seven certificates of nursery in- 

 spection; sixty-seven dealers certificates; 101 growers permits and 182 

 agents permits were issued in 1916-17. Twenty-two nurseries were found 

 to be infested with San Jose scale, being two less than in 1915-16. 



The report for 1916-17 shows that the numbers of scale infested nurs- 

 eries was gradually being decreased. The clean up work in 1916-17 was 

 carried on as in 1915-16. 



PLANT INSPECTION 1917-18 



The work of the Plant Inspection Service was carried on in 1917-18 by 

 Dr. Leonard Haseman, chief inspector and A. H. Hollinger and K. C. 

 Sullivan, deputies. 



One hundred twenty-three nurseries were inspected and 103 were cer- 

 tified. The nurseries inspected were located in forty-five different coun- 

 ties and included a total of 2,035 acres. Forty-four cases of imported stock 

 containing 425,849 plants received in seven different counties were inspected. 

 Fifteen nurseries were found infested with San Jose scale as compared to 

 twenty-two in 1916-17. This noticeable decrease in scale-infested nurseries 

 was due largely to the untiring efforts of the Plant Inspection Service.
