In view of the less serious injury from burning, lime-sulpliur lead arsenate 

 was more satisfactory than other sulphur lead arsenate sprays and Bordeaux 

 lead arsenate sprays. The kind of nozzle was not a factor in causing foliage 

 injury, provided an equal amount of spray was applied. A heavy application 

 of lime-sulphur lead arsenate is liable to cause foliage injury, whereas the 

 regular application will cause very slight, if any, injury. 



In order to avoid the injury from the drench spray of the combined nicotin 

 sulphate and lime-sulphur lead arsenate used for the green apple worm, it seems 

 necessary to reduce considerably the strength of the lime-sulphur solution. 

 Lime-sulphur weaker than the standard 1.008 or 1 : 37 is not so effective for 

 scab control.
