a ruthless weeding out of the sickly, 

 should prove a good practice. 



After the crop has started, the first 

 step in its protection from insects is to 

 keep it healthily growing, for a vigor- 

 ous plant resists attack more success- 

 fully than one the nutrition of which 

 is abnormal. The second step is to 

 keep the sharpest possible lookout for 

 trouble and treat it as soon as it ap- 

 pears. 



It is in the treatment of the plant 

 after the insect has appeared that 

 florists' practice appears to have 

 reached its most bewildering diversity. 

 Measures advocated by one grower as 

 a specific for a given species are com- 

 pletely discounted by another and an 

 opposite type of remedy substituted 

 for them. This difference of opinio.'i is 

 partly due to the fact that florists are 

 able to and do produce their wares 

 under so widely different conditions, 

 that in some instances what works for 

 one will fail for another, and partly 

 due to a failure to comprehend the 

 general principles which underlie 

 proper practice. The first is. of course. 

 an entire legitimate cause for differ- 

 ence but the latter is inexcusable. 



The treatment which shall be ad- 

 ministered to plants infested with par- 

 asites depends upon whether the in- 

 jury has reached a stage where treat- 

 ment other than prompt destruction is 

 worth while, what the plant itself will 

 stand without damage to grow a and 

 appearance, and the nature of the par- 

 asite. Injury beyond a point where the 

 plant may readily recover or of such 

 a character (s-ay borers in the main 

 stem of herbaceous plants) that 

 treatment is impracticable must be 

 followed by prompt destruction of the 

 plant and the parasite infesting it. 



If the injury is one from which the 

 plant may readily recover, the ques- 

 tion of treatment then becomes one of 

 nature, time and methods of applying. 

 The nature depends on the parasite 

 and upon the plant. 



If the parasite is an animal, the 

 question whether it consumes foliage 

 or sap must first be determined. If 

 the former, arsenicals should be used 

 if the plant will stand the necessary 

 dosage without injury to its structures 

 or to its appearance. If the latter, 

 nicotine or oil should be employed If 

 the plant will stand the necessary 

 treatment without serious injury to 

 structure or to appearance. In the 

 former case it is quite sufficient to 

 coat the foliage which is being con- 

 sumed while in the latter the insect it- 

 self must be thoroughly drenched. 

 This procedure will answer for the 

 bulk of the florists' insect pests. 



There are, however, certain species 

 to which these general rules will not 

 apply and each of them may be con- 

 sidered on its merits. For instance 

 many scale insects do not yield to con- 

 tact sprays of strength which will

leave the plants uninjured and hand 

 removal becomes necessary. Many of 

 the scales infesting palms are illus- 

 trations of this sort. Some chewing 

 insects attack plants of such a nature 

 that arsenical staining is inadmissable 

 and contact insecticides must be used, 

 as is the case with the Florida fern 

 caterpillar. 



There are crops, such as tomatoes 

 under glass, the insect pests of which 

 yield most easily to fumigation which 

 will destroy a chewing insect as read- 

 ily as a sucking one. 



For the purpose of bringing these 

 methods together and giving them 

 some sort of organization the writer 

 has induced Mr. Harr>- B. Weiss, of this 

 department to prepare a bulletin on 

 greenhouse insects. Especial atten- 

 tion has been given to this phase of 

 the florists business because it has 

 seemed to us that knowledge of that 

 part of the field has been in more 

 chaotic condition than any other. It 

 is purposed to distribute this bulletin 

 to the members of this association 

 who express a desire to consult it. 



No entomologist has made the in- 

 sect pests of the florist's crop a sub- 

 ject of sufficiently extended study and 

 research, and no really comprehensive 

 and helpful scheme of procedure can 

 be suggested until something of the 

 sort has been done. 



A live research committee of this 

 organization might set such a piece of 

 work going by cooperating with per- 

 sons already in experimental work 

 who are interested along this line, and 

 thus initiate a movement that would 

 prove a large factor in promoting 

 American floriculture.
