 place — for instance, on the potting shed

WHEN YOU WANT TO KNOW. 



If there's anything you want to know 

 about trade matters and don^t, there is 

 one inexhaustible mine for reference at 

 your disposal. Keview readers are al- 

 ways willing to help their fellows. It 

 seems there is always someone who ' 

 knows whatever a reader asks. More 

 than that, whoever knows, freely tells. 



For instance: An editorial para- 

 graph in The Review of March 16 stated . 

 a subscriber's query as to the name and 

 address of the manufacturer of 

 ' ' Gnarr 's Insecticide. ' ' Within a week 

 The Review had received replies from 

 four different readers, who stated that 

 the subscriber evidently meant th6 firm 

 of J. Schnarr & Co., Orlando, Fla. This 

 firm manufactures a spray formula 

 which is largely used for the control of 

 white fly on citrus trees in Florida. The 

 firm manufactures a number of sprays 

 and sprayers and has factories and 

 warehouses in several cities of the state. 

 This information was given briefly by 

 three readers. The fourth wrote at 

 greater length as follows: 



"The insecticide inquired about is 

 one of the most common of the insecti- 

 cides used in Florida in the control of 

 white fly on citrus trees. Of course, it 

 is only effective in the larvae 'stage, but 

 with systematic use it should be possi- 

 ble to eliminate white fly in greeir- 

 houses. 



"We use a lime-sulphur spray ma- 

 terial here for combating red spider, 

 and I have often wondered why it has 

 not been brought into use in green- 

 houses, as my experience in its use, 

 both on Asparagus plumosus and citrus 

 trees, has proved it more effective than 

 any methods I have seen tried in green- 

 houses. It can be diluted to such an 

 extent that it will not injure tender 

 foliage. It is^quite inexpensive. We 

 pay 40 cents a gallon for it in small 

 ((uantities and one gallon will sufiice for 

 two complete sprayings of one acre of 

 ground and clean out a heavy infesta- 

 tion of spider. The ba?is of the ef- 

 fectiveness of lime-sulphur solution is 

 not as a direct poison, but the solution, 

 in drying, leaves a residue that readily 

 oxidizes and produces sulphurous acid 

 fumes that destroy the spider even 

 when secluded in protected places. ' ' 



BORDEAUX MIXTURE. 



Bordeaux mixture . is a bluish-green 

 compound that settles out when freshly 

 slaked lime and a solution of copper 

 sulphate are mixed. Many formulas 

 have been recommended and used. The 

 r)-5-50 formula may be regarded as 

 standard. In such a formula the first 

 figure refers to the number of pounds 

 of copper sulphate, the second to the 

 pounds of the stone or hydrated lime, 

 and the third to the number of gallons 

 of water. Bordeaux must often be used 

 as weak as 2-2-50, on account of injury 

 to some plants. 



To make fifty gallons of Bordeaux 

 mixture, proceed as follows: 



Pulverize five pounds of copper 

 sulphate (blue vitriol), place in a glass, 

 wooden or brass vessel, and add two 

 or three gallons of hot water. In an- 

 other vessel slake five pounds of quick- 



J. C. WALLEY. 



FROM flour to flowers has boon the oecupational evolution of J. C Walley, 

 newly elected president of the Pittsburgh florists' and Gardeners' Associa- 

 tion. Working with his father, Mr. Walley grew up in the flour business at Butler, 

 Pa., his birthplace. Then, when the introduction of the roller process of grinding 

 flour began to make times hard for the old school of flour men, the young Mr. Walley 

 fared forth into the retail hardware business, which he left in 1913 to enter the 

 flower business. He entered in the company of H. L. Blind and C. E. Glenn, of 

 Evans City, Pa., and Smith Bros., of the Ovcrbrook Nursery, Pittsburgh. By these 

 men five greenhouses were erected, Mr. Walley acting as secretary of the company 

 they organized. In 1915 this firm consolidated with the MeCallum Co., of Pitts- 

 burgh, of which Mr. Walley is iiow a director. Since the consolidation a number 

 of houses h;n'e been built and planted with roses under Mr. Wiillev's management. 



lime in a small amount of water. When 

 the copper sulphate is all dissolved, 

 j)0ur into a barrel and add water to 

 make forty or forty five gallons. Xow 

 strain the lime into this, using a sieve 

 fifty meshes to the inch or a piece of 

 cheesecloth supported by ordinary 

 screening. Stir thoroughly, and add wa- 

 ter to the 50-gallon mark. The floccu- 

 lent substance which settles is the ef- 

 fective fungicide. Always stir vigor- 

 ously before filling the sprayer. Never 

 add the strong lime to strong vitriol. 

 Always add a large amount of water to 

 one or the other first. If used alone, 

 blue vitriol would not only wash off 

 quickly in a rain, but would cause a 

 severe burning of foliage. Lime is 

 added to neutralize this burning effect 

 of the copper. If the lime were abso- 

 lutely pure, only slightly more than one 

 pound would be required to neutralize 

 this burning effect. For many purposes 



an excess of lime is not objectionable 

 ilnd may be desirable. On ornamentals 

 Jill excess of lime augments spotting. In 

 such cases the least amount of lime pos- 

 sible should be used. Determine this by 

 .'ijiplying the cyanide test, as follows: 

 Secure from the druggist 10 cents' 

 worth of potassium ferrocyanide (yel- 

 low prussiate of potash) and dissolve it 

 in water in an 8-ounce bottle. Cut a 

 V-shaped slit in one side of the cork, 

 so that a few drops of the liquid can 

 bo obtained. When you add the lime to 

 the mixture, with constant stirring, 

 test with an occasional drop of the fer- 

 rocyanide. Enough lime has been added 

 when the ferrocyanide fails to give a 

 reddish-brown color.
