HORTICULTURAL ENTOMOLOGY. 



At the annual meeting of the Illinois State Agricultural Society at 

 Quincy, December 1875, I presented the outline of, and arguments 

 in favor of a plan of co-operation among horticulturists in contending 

 against their insect enemies. 



After presenting the plan somewhat in detail I offered the following 

 suggestions : 



"Before closing I will present you with a synopsis or tabulated ar- 

 rangement of the various divisions and sub-divisions mentioned, and 

 the remedies under each, in order to illustrate the plan of a paper 

 which I suggest be prepared under the supervision of your Society 

 and placed before the horticulturists and others of our State interested 

 in these operations. Of course it is far from complete, but will serve 

 to illustrate the plan suggested, which is all that is intended at 

 present. 



HORTICULTURE. 



1. Culture of the Nursery. 



2. Culture of the Orchard. 

 :'.. Culture of the Vineyard. 

 4. Culture of the Garden. 



We will take for the purpose of illustration, the "Culture of the 

 Orchard." 



I. CLEAN AND THOROUGH CULTURE. 



/ a. — In Plantmg, 



1. Select sound, healthy trees, free from insects or indications of 

 them, and from home nurseries. 



'1. Cultivate the ground at least one year previous to planting in 

 some crop requiring plowing; or plow and expose to winter previous. 



3. Do not plant in sod or grass ; and in the timbered sections, first 

 clear nut the stumps and logs, and clean generally. 



I. hip the roots in soap-suds before setting. 



■ fl- — OuMvatmg tin: Soil (including mulching, etc.) 



1. Cultivate the Boil in some crop requiring repeated plowings, 

 and that is harvested annually. Not in grass or winter wheat. Rotate.
