Show ABOUT SPRAYING. Provide for a Good Fruit Year by Fighting Peits. Tho Indications nro that this year will bo what orchardlsts call "a good fruit year." To instiro tho best ylold sprnylng should begin early. Spraying for codling moth Is begun when tho petnls nro fnllon, and should bo given as soon ns posstblo nfter that stage Tho calyx leaves aro woll open nnd nro uppermost, and it Is essential that poison ho deposited thero ns tho grent-or grent-or number of tho early brood ontor tho small npplo nt tho calyx. Tho small applo grows rapidly and tho second spraying should follow tho first In nt lenst ten days. Tho larvao that escapo tho first spraying will bo mature Insects within n short tlmo nfter tho first npplo has dropped, nnd a spray should bo given to protect tho fruit from tho second brood. At intervals in-tervals of about two or three wcoks, spraying for later broods haB proved profitable For' bitter rot or scab, bordeaux mixture applied beforo tho buds open destroy spores upon tho bark und twigs. It should bo combined with tho second nnd fourth sprays for codling moth, and if tho dlscaso has been very sorlous, ono or two moro later sprayings spray-ings will bo profitable Other Insects nnd diseases havo not boon noted ns serious whoro spraying for codling moth and bitter rot hnvo been nppllcd. In somo lnstnnccs a slnglo spraying has socurcd a vory groat lncrcaso In tho quantity of sound fruit, but In most cases n single spray has not been successful suc-cessful In proportion to repeated sprayings. Tho proportion of sound fruit on sprayed trees as compared with unsprnyed trees has varied In different dif-ferent seasons, but an nverago for tho past six years in nearly 50 per cent, number ono fruit from sprnyed trees, .v less than ten per cont from unsprnyed un-sprnyed trees. Tho per cent of mar-kctablo mar-kctablo fruit, Including tho second grado, has .shown slightly greater differences dif-ferences In favor of sprayed trees. Tho cumulntlvo effect of spraying has boon noted in tho greater freedom free-dom from Insects nnd diseases of tho experiment station orchards and vineyards vine-yards compared with neighboring plantations which havo not been sprayed. Tho orchards havo suffored no injury from cankor worm, leaf-crumplor leaf-crumplor or tent caterpillar, which havo boen very numerous In neighboring neighbor-ing orchards during several seasons. Tho protection from fungus has been fully ns valuable During tho seasons 1905-190G practically no loss was occasioned occa-sioned by bittor rot, scab or ruBt, whilo unsprnyed orchards in this locality lo-cality hnvo Buffered seriously. In sprnylng peach trees to provent brown rot nnd lent curl tho first spray should bo applied beforo tho leaf buds open. Tho follngo of tho peach Is much more easily injured than la that of tho applo, nnd nfter tho trees aro In leaf tho bordeaux mlxturo should bo reduced re-duced to half strength. As tho fruit reaches mnturlty tho uso of bordeaux Is llablo to discolor tho fruit Tho colorless ammonlncal solution of coppor carbonato has boon used during ripening, but has been loss offcctlvo than bordeaux. Tho plum varieties differ consider-nbly consider-nbly in their liability to spray burn, but as a rule tho bordeaux should bo diluted half strength for plums. Tho sprnylng of tho vlnoyard to provent pro-vent mlldow has been uniformly successful. suc-cessful. Tho crops from unsprayed vines havo in sovoral seasons bcon almost al-most total failures whon tho sprayed vinos havo given fair crops. It. E. Eastman. |
