In this group there was about 90 to 95% defoliation of orange 
trees except in a few protected places. The grapefruit trees 
were completely defoliated.

The defoliation in this group was not sufficient to influence the 
number of white flies or other pests to a degree to be of economic 
importance. 
- CONDITION OF THE CITRUS TREES AT THE TIME OF THE FREEZE 
Owing to the prolonged period of warm weather, citrus trees 
were in a growing condition. So far as can be determined, the 
condition of growth was in the same state of advancement in 
every part of the state. Grapefruit trees, especially, were in the 
full flush of growth. Orange trees were also growing, and many 
were in full bloom. Tangerine trees had not reached the ad- 
vanced state of growth of either the grapefruit or orange trees, 
but some growth was taking place. Young trees, especially, were 
growing vigorously. It is due to this condition of growth that 
the trees were injured so severely. Tangerine trees, being quite 
dormant, were not damaged very seriously and if other citrus 
trees had been equally dormant, little damage would have re- 
sulted from the cold. 
The cold wave not only seriously damaged the citrus and other 
semi-tropical trees and shrubs, but also it was of the greatest im- 
portance in reducing the numbers of injurious pests which infest- 
ed the trees. Some of these were frozen outright, while others 
were affected when the plant was defoliated or killed.
