unusual drop of bud scales and the small leaves have a 

 characteristic spoon-shaped deformity. Sticky honeydew 

 is abundant on the infested trees. Here again, are condi- 

 tions where late treatment with a lime-sulfur wash, to which 

 a tobacco extract such as black leaf 40 has been added in the 

 proportion of 1 to 800, is justified. This will destroy many 

 of the early appearing thrips, and if the insect is numerous, 

 another spraying may be advisable just as soon as the young 

 pears have separated sufficiently so the insects at the base of 

 the stems are exposed. It may even be necessary to give 

 another spraying after the blossoms fall. This insect works 

 so rapidly and seeks shelter so persistently, that promptness 

 in treatment is a prime essential to successful work. 



The false tarnished plant bug is capable of producing on 

 pears, a condition similar to that caused by the red bug on 

 apples, namely an irregular, gnarly development, the de- 

 pressions being marked by pithy cores which may extend 

 some distance into the fruit. The young begin to appear 

 when the trees are coming into blossom, and the pest can be 

 most successfully controlled by spraying with a tobacco 

 preparation such as black leaf 40, using % of a pint to 100 

 gals, of water to which is added 3 lbs. of soap. Some grow- 

 ers have been satisfied to delay the regular lime-sulfur spray- 

 ing for San Jose scale, adding thereto the requisite amount 

 of the tobacco extract. 



Specific directions might be given for the control ot 

 other insects and this paper continued to an almost indefinite 

 length. The main thing is to appreciate the fact that, as s* 

 rule, most insects can be controlled if one understands the 

 method of attack. Complaints of unsuccessful work invari- 

 ably lead us to ascertain the cause. We should remember 

 that a chain is not stronger than its weakest link and any 

 defect in our method of spraying, be it lack of thoroughness, 

 untimeliness, a poor or unsuitable material, is bound to have 

 disastrous results. We would urge upon all progressive fruit 

 growers, the desirability of adopting a system of spraying 

 which may be profitably followed year after year, becaust; 

 in this manner alone, can the best results be obtained, 

 especially in controlling such a pest as the codling moth.
