poison should be made after the leaves come out, at about the time 

 the cluster buds are separating. This application comes at the 

 time for the first scab spraying, and can well be made in combina- 

 tion with it. 



PEACH BORER. 



The peach borer is without question the most common and the 

 most destructive insect affecting peach trees, and is a pest that 

 has generally given growers no little trouble and concern. 



A method of control has recently been recommended by the 

 California experiment station, which has proven very effective, 

 satisfactory and easily applied. The remedy consists of painting 

 the trunks and crown of the trees with hot asphalt. The dirt is 



removed from about the crown of the 

 tree. Hard asphalt of the grade C 

 and D is melted in a kettle. The oper- 

 ation of heating should be stopped at 

 a point where a small portion of the 

 asphalt remains unmelted and floats 

 on the top of the kettle. If the heating 

 is discontinued at this point it is then 

 possible to carry the kettle from tree 

 to tree with little or no inconvenience 

 from the hot asphalt. The prepara- 

 tion is then applied with a brush, giv- 

 ing one or two coats. This treatment 

 is reported as being very effective, not 

 only for preventing borers from getting 

 into the trees, but also for destroying 

 those already in. 



SAN JOSE SCALE. 



In some localities of the State 

 San Jose scale is a serious menace to 

 the orchardists and is a trouble not 

 likely to be eradicated when, it once 

 appears in a community, although it 

 may be held in check by timely spray- 

 ing. If the infestation has become serious before it is noticed, two 

 applications will likely be necessary the first season. The first one 

 should be made as soon after the trees become dormant in the fall 

 as possible; the second one as late iA the spring before growth
