140 AROUND THE YEAR IN THE GARDEN 



many years been Bordeaux mixture. This may be made 

 at home, but for use on a small scale a good ready-prepared 

 sort is more satisfactory. It can be had in the pure form 

 or combined with arsenate of lead. This double mixture 

 is effective against both diseases and chewing insects. A 

 double-barrelled dry spray is to be had in powdered ar- 

 senate of lead and sulphur, which is convenient to apply 

 to the vine crops. 



A small amount each of arsenate of lead; Bordeaux mix- 

 ture (or the two combined); tobacco dust; some nicotine 

 spray, and kerosene emulsion will cost little but will furnish 

 protection from all the troubles likely to be encountered. 

 Most of these things will keep indefinitely. The important 

 point is to have them on hand to use at once. As some of 

 these things in their concentrated forms are deadly poisons, 

 they should be kept out of the way of children. In using 

 any of these things follow directions carefully. Different 

 makes vary considerably in analysis. 



Begin early in the season to use a combined Bordeaux- 

 and-arsenate-of-lead spray on such vegetables and flowers 

 as are likely to need it, and go over them at intervals of 

 ten days or so to keep all new growth covered. In addition 

 use tobacco dust freely wherever trouble from bugs or plant 

 lice is anticipated. 



Besides these precautions remember that everything you 

 can do to keep your vegetables and flowers in vigorous, 

 growing conditions will make them less likely to be attacked 

 or to be seriously injured by the attacks of either insects 

 or diseases.
