J. J Davis DaTts entomologist of ot the Purdue Pur- Pur duo due experiment station From th the tho results of ot past experiments It was found that lime sulphur lime sulphur failed to kill killa a large per cent of the scale ecale Something Something Some Some- thing more effective has bas to be used I The recommendation made at this conference was Willi that oil sprays be used when the tre trees ll were In the dormant state The sprays found effective were the miscible oils and boiled lubricating lu lu- oil all emulsion Various mis- mis oils are advertised In the horticultural horti cultural publications These must be used at lit the strength recommended by bythe bythe the manufacturers I The boiled lubricating oil emulsion Is made from the formula as recommended recommended mended by the Unit United ell States Department Depart ment went of ot Agriculture and li is as follows I Diamond oil 1 gallon liquid potash fish flak oil soap 1 pound water H gallon This constitutes the stock solution A A. spray solution containing from tram 2 to 8 per cent of at oil was recommended depending upon the seriousness of tho Infection A 2 per cent solution Is II made by br adding 1 gallons of ot the stock solution to a gallon 50 barrel of t lip spray ray and a 8 3 per cent solution Is made by br adding 2 gallons of at the stock emulsion I Those Interested In the details of ot making this stock emulsion should write the Purdue experiment station Lafayette Ind Those using only a a arnall amount of the emulsion during the season eason say three or four tour barrels will probably find It to their a advantage tage tape to purchase the material ready prepared due to the fact tact that It takes some special equipment to make It It Is necessary to pump this ma ma- material with n 1 force torce pump while It Is II very verr hot which Is exceedingly hard hardon hardon on on the pump unless It ft Is I. equipped with metal valves and special packing pack pack- Ing Leather packing and valves burn burnout burnout burnout out In a very short time Manufacturers Manufacturers Manufacturers who make the material In large lots iota can buy the raw material at a n decided de tte 1 advantage j 1011 Oil emulsion Is recommended only as as an Insecticide anI and Is not a fungi clde tide It will w not control peach leaf leat curl and the usual fungicide has hns to tobe tobe tobe be applied for tor curl sulphur Lime Is II generally used for this and should bo bit applied In advance of ot the oil all spray as asIt asIt I It will wUl penetrate the crevices better than If It applied after the oil olt This oil all emulsion has several advantages over lime It has tae been proven more mor effective It Ismore Is II more pleasant to use as It does not Injure the eyes or skin of ot the operator operator opera opera- tor It does not corrode the pump but bet makes It work perfectly the cost coat Is II less than thon one half that of sul lime The stock solution will wUl last a all season If not allowed to freeze Fruit growers generally are very enthusiastic en en- over this new spray Experiments Experiments Ex Ex- Ex tho the past season Indicate that this material can be used as a summer ummer spray to kill aphis and hatch hatchIng hatchIng Ing scale |
