Pomelo (Grapefruit) 



The pomelo, though a thrifty grower and free bearer, not more 

 liable to frost injury than the orange, is particularly liable to attacks 

 of Black Scale and Mealy Bug, Yearly fumigation is almost a 

 necessity. It is fairly profitable when grown under right condi- 

 tions. (See also under Lemons.) 



Peach 



Very easily grown and a prolific bearer all over the County, no 

 yellows or rosette known, mildly subject to attacks of Greedy and 

 San Jose Scale, also Green Aphis and the Black Peach Aphis (Aphis 

 persicae niger) which latter is somewhat menacing where it has 

 been introduced. Peach root borer and peach twig borer also do 

 some injury; a fungus disease known as curl leaf has to be corn- 

 batted. Some varieties are quite free from it, however, and spray- 

 ing with Bordeaux Mixture soon after the leaves fall, and perhaps 

 in spring controls it well. 



Pears 



The pear tree grows thriftily anywhere in the County and if 

 kept free from insects and with sufficient moisture, bears well. It 

 has been much neglected, owing to the pear blight, in latter years 

 south of the mountains, but produces excellent profits to quite a 

 number of growers on the north slopes, and in the Antelope Val- 

 ley region. It is quite subject to the deciduous Red Spider, the 

 Greedy Scale and the San Jose Scale, and in some localities has 

 been greatly injured by the Pear Blight, which, however, is well 

 controlled by Bordeaux Mixture and Lime-Sulphur spray. 



Plum 



This is perhaps the most productive and healthy fruit tree grown 

 in our County and the freest from insect troubles. It fruits well 

 everywhere, though some varieties are better in this respect than 

 others, and a little Greedy, Black and San Jose Scale, usually 

 unimportant, are about all the insects found on it. 



Prune 



This tree, planted to a considerable extent here in former years, 

 has more lately been much neglected, as in this locality we can not 

 seem to produce fruit equal to counties further north, and' the low 

 markets do not warrant growing of inferior fruit. 



Insect pests attacking it are about the same as for the plum.
