time there is a considerable overproduction of mint oil resulting in a 

 market decrease in price. Until further work has been done on the 

 storage of celery for winter and spring market, any large increase in 

 celery acreage would likewise result in rendering celery growing unprofit- 

 able. Because of these facts, the tendency in the extension work with 

 muck soils during the past season has been to direct the prospective 

 muck farmer toward a system of diversified farming, with a selection 

 of crops which are in general demand, adapted to muck soils and which, 

 at the same time, are able to withstand without injury, a considerable 

 amount of frost. Special emphasis has been placed on proper fertiliza- 

 tion, the rate of application per acre also being considered in the ar- 

 rangement of the plots for 1922. 



REPORT OF EXTENSION WORK IN INSECT CONTROL 



BY. J. H. HARMAN 



On May 10th, 1922 the writer took up his duties as Extension Specialist 

 in Entomology. 



Since that time the aim has been to give the farmer and grower all 

 possible assistance in his fight against his insect enemies. This has 

 been accomplished by means of demonstrations and advice setting forth 

 the use and application of sprays and dusts, and adopting other remedial 

 measures. 



Demonstrations have been carried on concerning the peach-tree borer, 

 flat-headed apple tree borer, grape-berry moth, pea-louse, codling-moth and 

 chinch-bug. 



The county agents contributed toward the success of all demonstra- 

 tions, through publicity, lining up the farmers likely to be benefited, 

 and lending personal assistance. 



The great majority of all demonstrations were purely emergency work. 

 The outstanding illustration is that of the fight against the chinch-bug 

 in the southern part of the State. 



About the seventeenth of July, 1922, we were called upon by the 

 county agent of Monroe county, to assist him in the fight against the 

 chinch-bug. The writer with two assistants went over the situation 

 taking into consideration the type of soil, general location, and intensity 

 of infestation. The local newspapers co-operated to the extent of pub- 

 lishing directions for measures of control, also announcing the time and 

 place of demonstrations. 



The first demonstration was launched near Monroe to which were 

 invited farmers of the immediate vicinity. Actual operations were car- 

 ried on and the tar and dust barriers were laid down halting the advance 

 of the insect. After the demonstration, the three of us scattered over 

 the county, selecting sites suitably located so that the entire county 

 was covered in six demonstrations. These created considerable enthusi-
