diseased leaves as soon as they appear. In bad cases remove affected 



plants and destroy them by burning. Some blights are carried from plant 



to plant h}' insects. Keeping insect pests in clieck, therefore, means less 



blight. Careful pruning, staking and cultivation help; rotation of crops 



also. No. 9 is an excellent fungicide for many blight diseases on tomatoes. 



Potato "Bugs," Blight: Use No. 1 for the first time 



Potatoes. wlicn plants have about six to eight leaves, and continue 



for several sprayings at intervals of ten days or two 



weeks. Later sprayings may be given at any time if "bugs" are active.

 mands on cabbage. Cauliflower should not be sprayed 

 after heads begin to form. Use dry hellebore, which is harmless to man, if 

 cauliflower heads are being eaten by insects. Cabbages can be sprayed 

 with any arsenical up to within a few weeks of gathering. They are not 

 easily injured 1)}' Paris green, and some growers use it as strong as three 

 pounds in fifty gallons of water. A quart of soft soap, or eight quarts of 

 ver}' strong soap-suds should be used in every fifty gallons, to insure the 

 liquid's spreading over the leaf. Root Maggot: Steep two ounces of white 

 hellebore in one quart of water for an hour, dilute with water to make one 

 gallon of the decoction. Apply with sprinkling can a few days after plants 

 are set out; five days later apply again, and a third application five days 

 after the second. Apply seven or eight times more at weekly intervals. 



Lice: Watch bushes carefully and use No. 4 whenever 

 Rose. the pests are seen. Spray forcildj-. Rose Beetles. Rose 



Chafers: jarring on to cloth beneath bush early in morn- 

 ing, then collect and destroy. White hellebore dry when leaves are moist. 

 Leaf-cutting Bee: Dissolve one-half pound of whale oil soap in four gal- 

 lons of water, and sprinkle leaves when plants are not in bloom; while 

 foliage is still wet with this solution dust with powdered sulphur. Mildew: 

 Use No. 6 or No. 9 at the verj' first appearance, and repeat whenever 

 necessary. No. 6 stains white paint. Dusting powdered sulphur on leaves 

 when they arc damp is "-nod. Black Spot: Use No. 9 every week. 



Controlling the Codling Moth with One, or at Most, Two 

 Sprayings: Prof. Ball of Utah, and other workers on the Pacific 

 Coa.st have revolutionized sprayiug for the Codling Moth where this 

 insect alone i.s to be combated. They find that by one. or. at most, two 

 sjMTtyings, jndiciotisly timed and pr ijierly a])]died, almost the entire 

 crop of fruit can be saved. 



Pall's method is based ])riniarily on two important facts. He 

 claiius that wherever u])on the apple the eggs of the first brood are 

 laid, a great majority of the young worms (over | ) coming there- 

 from crawl to the calyx and enter there. Secondly, and a condition 

 which has not heen taken into consideration hitherto by entomologists, 

 is the fact that in a young apple, immediatel\- after the petals fall, there 

 are two cavities at the calyx end, the stamen "bars" (Ball) roofing the
