TWENTY-NINTH FRUIT-GROWERS' CONVENTION. 



The timing of the later sprayings can be determined by the band 

 method. This consists in placing bands of burlap about the trunks of 

 a number of trees in the orchard and keeping a careful record of the 

 codling worms found beneath them. For the purposes of this study 

 the bands should be removed at least once a week, and when the worms 

 beneath them have been counted and destroyed the bands should be 

 replaced. Spraying for the second brood should begin as soon as the 

 worms become common and comparatively numerous beneath the bands, 

 and as long as they continue to appear in numbers the spraying should 

 be repeated at intervals of about three weeks to effectively protect the fruit 

 against this second brood. This may require as much as three treatments 

 in the Pajaro Valley, possibly even four in the interior. These studies 

 will, if carefully prosecuted, indicate for each orchard and season whether 

 two or three sprayings or five or six are necessary to obtain control of 

 the codling worm. It may be possible in those localities Avhere the 

 seasonal variation is not great to determine a definite program for 

 times of spraying by continuing these studies through two or three 

 years. Indeed, the Avhole series of results obtained by us indicates the 

 necessity of a proper timing of the spraying, if the best returns are to 

 be expected, and this timing, as before stated, can only be determined by 

 a study of the development of the worms. 



In conclusion, we can say that our spraying experiments in the 

 Pajaro Valley this season have demonstrated the possibility of keeping 

 the loss from the codling worm down to about five per cent of the crop, 

 as against from twenty-five to forty per cent where no spraying is 

 done. The cost of this work will be from fifteen to thirty cents per 

 tree for the year's work, reckoning on trees ten or twelve years old. 



Our positive recommendations as to the all-important question of 

 timing the sprays are : 



First — In every locality, until definitely proven that it can be 

 omitted, spray at such a time as to leave a dose of poison in the 

 blossom cup. 



Second — One or more sprays for the spring brood of moths, as deter- 

 mined by the breeding jar. 



Third — Spray against the summer and fall worms, as determined by 

 the examination of bands. 



RESOLUTIONS RELATIVE TO WORMY APPLES. 



MR. ROGERS, of Watsonville, presented the following resolutions, 

 in pursuance of instructions from the Pajaro Valley Orchard Associa- 

 tion : 



Whereas, It is an established fact that some of the leading markets of our State are 

 supplied with such large quantities of wormy and scaly apples that those markets are 

 constantly glutted with this inferior grade of fruit, to such an extent that there is slight
