Iron Arsenate as Insecticide 



Experiments with iron arsenate as an in- 

 secticide have been conducted for several 

 years in France by Messrs. V. Vermorel 

 and E. Dantony. A report of their work 

 is given in the "Experiment Station Rec- 

 ord" of the United States Department of 

 Agriculture, Washington, D. C, as fol- 

 lows : 



"On the basis of several years' experi- 

 ments the authors conclude that the ac- 

 ton of iron arsenate, as an insecticide, is 

 equal and sometimes superior to that of 

 lead arsenate. It is easily prepared for use 

 and its adhesive power is greater than that 

 of similar products. 



"Among the advantages that this insecti- 

 cide has over lead arsenate are its charac- 

 teristic color which prevents a mistaken 

 use and the presence of iron in place of 

 lead, the former having a beneficial effect 

 upon the foliage. The most important ad- 

 vantage, however, is the cheapness of the 

 product due to the cheapness of sulphate of 

 iron as compared with acetate of lead."

At the Woburn (England) Experimental 

 Fruit Farm, investigations have shown that 

 the clear lime water made by slaking three 

 pounds of quicklime in about one hundred 

 gallons of water, and then adding eighty- 

 six gallons of this clear solution to fourteen 

 gallons of water in which six pounds, six and 

 one-half "Ounces of copper sulphate have been 

 dissolved, will yield one hundred gallons 

 of Bordeaux mixture superior to and cheap- 

 er than that made according to the com- 

 monly accepted formula. As our ordinary 

 commercial forms of quicklime vary exceed- 

 ingly in its essential constituent, viz., cal- 

 cium oxide, the potassium ferro-cyanide test 

 becomes essential if anyone is disposed to 

 give this formula a trial. — Exchange. 



Niagara Growers Meet 



Harmony prevailed as usual at the an- 

 nual gathering of the Niagara Peninsula 

 Fruit Growers' Association held at St. 

 Catharines, Ont., on Jan. 13. President 

 Bunting was in the chair, with Secretary 

 Carl Fisher presenting the reports of the 

 year. Officers were elected for the various 

 districts and a series of meetings were ar- 

 ranged for the coming spring. 



It was moved by Major Roberts and W. 

 H. Hough that in the opinion of the asso- 

 ciation it is necessary that an adequate 

 census of the amount of acreages of fruit 

 under growth and the ages of trees be tak- 

 en, and that both Provincial and Domin- 

 ion departments be requested to assist. 



Mr. P. W. Hodgetts of the provincial 

 department stated that a census taker had 

 been placed in the district to get informa- 

 tion and that a report would be issued 

 early. Major Roberts thought that the 

 number of young, non-bearing trees should 

 also be taken into consideration. It was 

 very essential in the mind of the president 

 that such a census as Major Roberts had 

 outlined should be taken. Unless this was 

 done, the growers would not be able to get 

 proper information relative to the setting 

 out of the different varieties of trees. 



A resolution was adopted setting forth 

 that "in view of the rapidly increasing out- 

 put of tender fruits from the Niagara 

 peninsula, and from the fact that under 

 the present methods and conditions, the 

 distribution of these fruits is not satisfac- 

 torily nor systematically conducted, a situ- 

 ation which results in dissatisfaction to the 

 consumer and often in loss and disaster to 

 the shipper, we would urge that a commit- 

 tee of prominent growers, selected from the 

 members of this association, located at dif- 

 ferent shipping points in the district, be 



appointed to take the matter under con- 

 sideration, to secure data, and, if possible, 

 to formulate a plan whereby the present 

 unsatisfactory conditions may be if not 

 wholly eliminated, at least to a large de- 

 gree remedied." 



Another resolution was passed as fol- 

 lows : "In view of the amalgamation and 

 merging of the various canning factories of 

 the country into one or more large holding 

 companies, it is in the interests of the fruit 

 and vegetable growers that a committee of 

 growers be appointed by this association, 

 who shall have authority and whose duty 

 shall be to treat with these companies with 

 the object of arriving at fair and equitable 

 uniform prices for the various fruits and 

 vegetables produced in this district, and 

 used by the canning factories in their busi- 

 ness." 



The special spraying committee reported 

 that after experimenting they had found 

 that curl leaf on peach trees can be pre- 

 vented if sprayed with lime and sulphur 

 previous to the lime the buds begin to 

 grow. If the leaves start and curl while 

 the leaf season is on the pest cannot well 

 be checked. The committee experimented 

 in one orchard by spraying all but five trees 

 in the manner advised. In every case, save 

 those of the five trees, ^the crop averaged 

 ten baskets. The other five lost all their 

 foliage and fruit. — J. A. S

The New Insecticide Discovery Which Kills 

 Plant Lice of Every Species 



"There are insecticides and insecticides and 

 then again some more. The terrible ravages of 

 insect pests in these latter days has furnished the 

 incentive for the making and exploiting of num- 

 berless compounds for special or general purposes 

 in the never-ending warfare upon insect pests. 

 We know of none, however, which has more 

 quickly demonstrated its efficiency than the re- 

 cently introduced 'Aphine,' which, in the course 

 of a comparatively few weeks has become a 'alis- 

 man among horticulturists of unimpeachable ver- 

 acity and unquestioned skill." — "Horticulture."
