THE WORK THIS SEASON

THE WORK THIS SEASON
 W. H. Darrow the fruit specialist at the college recently sent to the New Lon don County Farm Bureau office some valuable information and suggestions as F to spraying particulars for this year. The following is what MT. Darraw has to 1 say in regard to spraying, spray equip | ment and spray materials. Anyone wish | | ing further information can secure 1t at ] the farm bureau office in the Shannon | | building In regard to spray materials a state | ment issued at tht farm bureau office | says: Have you purchased your spray materials yet? Don't get caught with no spray materials on hand. when spray ing time arrives. Prices are much lower than last year. Recent investigations in the west have shown that the powdered lead arsenates are physically superior to the paste forms and that they are general 1 ly the advisable forms to use. Particu- l larly is this true if one is not near the point of manufacture, so as to insure a
 freshly made paste which has had no
 opportunity to dry out or freeze.
 Spraying Equipment-All spraying
 equipment should be inspected. oiled and
 put in running order before the spraying
 season arrives. There is no time on
 spraying days to adjust carburetors.
 pack pumps, mend hose and scrape out nozzles Every minute should be used in applying the protective coating to fruit and foliage.
 Spraying Schedule for Apples-The
 number of spray applications that should } be made will vary with the insect and
 fungous pests present in the particular
 locality. If the trees are not affected
 with scale aphis blister mite or red !. spider the first application (delsyed dor ' l Al. L. . not troublesome, the ten-day spray can ' be left out. On the other hand where the curculio is especially abundant. an = extra application should be made about a week or ten days after the ten-day
 spray.
 In some sections of New England, the
 apply Tnaggot or railroad worm is a so.
 rious pest of the apple. Although thu |. thirty-day spray will help in the contro T of this insect, in most cases one or twS 4 special spray applications will have tt d be made using arsenate of lead only. I'm . first of these should he applied durinl - first week in July and the second abou . two weeks later Cultivation will als " help materially in the control of this pest : Delayed Dormant Spray-To be applie
 just as the buds are breaking open fl S the spring. Use commercial lime sulphur ,f gallon to to gallons of water, fo "a scale and blister mite. If aphis ar It present add nicotine sulphate at the rat ,e of one-half pint to 50 gallons of the ma - terial.
 Pink or Pre-blossom Spray (importar ,s scab spray)-To be applied just before tn n- blossoms begin to open. Use lime sulphur
 1 gallon to 40 gallons of the water fo tv scab. Add arsenate of lead, one an ht one-half pounds of the powder. to 5(
 gallon tank, if leaf eating insects ar f. present. (Canker worms, ten-caterpi ! ars bud-mlh or brown tsil Gnoth.) .ic Calyx Spray (very Tmportant)-To ,v applied within a week after the peta N' fall. Use the same materials as in u
 pink spray. Add nicotine sulphate at u
 rate of eHe-half pint to 50 gallons of u IT material, if red bugs are present. ty Ten Day Spray To " applied from ten days to two weeks aft he the oalyx application, using arsenate
 lead at the rate of one and oneIha 'e' pounds of powder to 50 gallon sof wate If frngous diseases are present aC ~ ie summer strength lime sulphur. (OH V' this application where the curculio is n c troublesome.)
 U,' Thirty-day Spray Qmportantl-To applied four or five weeks after t 'l calyx spray. Use arsenate of lead al
 lime sulphur of the same strength as in
 3 and 4. This application is for coolf - moth. scab, sooty blotch and sever
 ether less important pests.

In sor the sections of New England injury to t the foliage has resulted from the use of t icy lime sulphur and aFsenate of lead eol rm bination. In similar climates this h of been avoided by using the bordeaux m vas ture or self boiled lime sulphur as su
 gested above. Some writers advise 1 is addition of about lbs. of lime to 50 g nto Ions of the dilute lime-sulphur previ1 am to adding the arsenate of lead as D mo- ventative of burning. This would se in to be worthy of trial by oreharists W ar care to make an experiment In a
