The disc nozzles, which make a fine mist, should be used for all other spraying if conditions permit. A great many experi- ment station men and horticulturists advise against the use of Bordeaux nozzles on the ground that more mixture is used and that as even a distribution of the mixture over the surface is not obtained; but under Missouri conditions, leaving the matter of filling the calyx cavaties of the young fruits entirely out of the question, there are many days during the spring that reasonably good work may be done with Bordeaux nozzles when it is practically impossible to work at all with nozzles which make a fine mist spray. The greater range and penetration of Bordeaux nozzles also make it possible for men working from a tower to more effectually spray the inner portion of large trees which can not be conveniently reached by nozzles making a fine spray, except under conditions of still atmosphere. For spraying trees that are too tall for the tops to be conveniently sprayed from the ground, the outfit, whether power machine or hand pump, should be provided with a tower suf- ficiently high to enable the nozzleman to direct the spray downward into the blossoms or over the trees. The work on large trees will not only be more thorough but also will be much more easily done. t^- , • . , ^ . Pink just showing. BLOSSOMS SHOWING TIME TO SPRAY. The most opportune time to make the first spraying for apple scab is just as the pink is beginning to show in the bloom. The orchardist who has several days spraying to do, however, can not wait until that time and should begin as soon as the cluster buds are separating in order to finish before the blossoms open. The second spraying for apple scab is made with the first spraying for codling moth and should be made just after the petals have Please note
