REPORT OF THE STATE ENTOMOLOGIST I9OO 979 



Mayjn.^ Tree 69. The leaves are partly out and there are a few- 

 blossom buds. The leaves of tree 70 are farther out and there are many 

 blossom buds. Tree 71 is dead. There are many blossoms on trees 86- 

 88, and the leaves are starting, but trees 86 and 87 are a little later 

 than 88. 



May 14. The leaves on tree 69 are half out and rather abundant. The 

 blossoms are few. The tree has been badly injured, probably by the ex- 

 cessive abundance of the San Jose scale. The leaves are half out on tree 

 70 and there are many blossoms. The numerous leaves are starting and 

 the bloom is abundant on trees 86-88. 



July 2. Living, young scales are very abundant on trees 69 and 70. 

 A few living scales are found on tree 86 and rather few on trees 87 

 and 88. 



July 16. These trees were sprayed with Good's whale oil soap solu- 

 tion as before, except that one pound was used for each five gallons. The 

 day was very warm, practically clear and with a breeze most of the time. 



July 30. On tree 69 there are apparently no living scales, and on 

 trees 70, 86-88 most of the young scale insects appear to be dead. 



Aug. 3. Living young are rather abundant on trees 69 and 70. 

 There are very few or no living young on tree 86. They are rather 

 abundant on tree 87, and but few on tree 88. 



Sep. 7. Living young are very abundant on all this lot of trees, 

 specially on 70. 



Leggetfs anchor brand, i\ pounds to the gallon. Six trees were 

 treated with this strength of the insecticide. The conditions and time 

 were the same as in the preceding experiments. Trees 33-35, globe 

 peach respectively 16, 14 and 13 feet high, were moderately infested with 

 the San Jose scale except the first, which was fortunate in having but 

 few of the pests. Tree in, a Kieffer pear 8 feet high, was infested with 

 but few scales. Tree 112, a beurre d'Anjou 7 feet high, was moderately 

 infested, and tree 113, a 10 foot pear of the same kind, was apparently 

 free from the scale. 



Ap. 19. Trees 33-35, in- 13, have a white, dry appearance, very 

 different from the moist condition of those treated with Good's soap - 



May 11. Leaves have started on tree in, are just starting on tree 

 112 and are out a little way on tree 113. The buds of all are uninjured, 

 and the trunk and limbs are considerably whitened by the soap. 



May 14. There are many blossoms on trees 33-35 and the leaves are 

 starting well. The leaves are out pretty well on trees in and 113, and 

 the blossoms are open and very abundant. The leaves are thin and but 

 half out on tree 112 and there are no blossoms.
