The I'esults from these treatments should be satisfactorj 

 as far as scab, codling moth, cureulio and fungus diseases 

 are concerned. 



But we also hav€ the aphis to contend with, and many 

 of the growers in the state of New Jersey find it very 

 difficult to control. I believe it does more damage to our 

 a,pple crop than any one other insect. These insects de- 

 posit their eggs on the tender wood of our apple trees in 

 the fall, and they hatch in the following spring when the 

 "weather conditions are favorable. The only time they can 

 he controlled is shortly after they hatch and before the 

 leaves advance enough to give them protection. Conse- 

 quently, the time for -effectively controlling green and rosy 

 aphis is very limited indeed, and we must be on the alert af 

 we expect to control them. 



Very few growers would notici their presence on the 

 trees until the curled condition of the leaves attracted 

 their attention, when it would be too late to control them 

 that year. It seems very unfortunate something cannot be 

 found to destroj^ the aphis while in the egg state. Lime 

 Sulj)hur winter strength and Sc^lecide will reduce the hatch, 

 "but not sufficient to control. It is claimed by some profes- 

 sors that aphis can be controlled by combining Black Leaf 

 40 with the dormant spray, which may be correct in some 

 •cases. But some experiments carried on in my orchard by 

 Dr. Headle«, our State Entomologist, proved conclusively 

 the aphis are not always hatched at that time. Consequent- 

 ly, if Black Leaf 40 were u»eA when the lice were not pres- 

 ent the material would be wasted and the crop of fruit 

 v^^ould in all probability be badly damaged unless later 

 treatments were applied. 



After considerable experience, some of which has been 

 very costly, I have decided on the following plan of control 

 ing aphis, and it has proven entirely satisfactory the last 

 two seasons. First watch tlie buds very closely, for there 

 IS where the lice will first appear. If the aphis are hatch- 

 ing when you are applying the dormant Lime Sulphur add
