sending his product all over the country, and is not basing 

 the strength which he recommends on the different insects. 

 Where the gypsy molh is prevalent it will be found that the 

 poison -must be used much stronger than where only the 

 codling moth or canker worm are considered. My rule for 

 spraying for the gypsy moth is one pound of arsenate of lead 

 to ten gallons of water, for the codling moth, canker worm 

 and small brown-tail moth, one pound. to fifteen gallons of 

 water. As the season advances in spraying for any insect I 

 increase the strength of the poison. Arsenate of lead should 

 not be used on the foliage of peach trees. For spraying ap- 

 ple, pear and cherry trees, apply the poison thoroughly to 

 all of the foliage and blossoms, first, as soon as the petals have 

 fallen. Follow with another application ten days or two 

 weeks later. Many of our best growers consider it wise to 

 give three, four or five applications during the season, but 

 I do not think this is ahvays necessary. 



For fungous growth we have not yet reached our ideal 

 remedy, and it would now look as though some form of sul- 

 fur might take the place of bordeaux mixture. During the 

 past season in many places home-made bordeaux rusted the 

 fruit badly, but the summer sprays of lime-sulfur not 

 only controlled diseases, but did not injure the fruit. It was 

 also found that the commercially made bordeaux mixed with 

 arsenate of lead caused very little rusting. The only reason 

 which can be given for the injury in one case and not in the 

 other, is that the bordeaux was better prepared in the com- 

 mercial mixture. Where a fungicide is to be used I would 

 recommend mixing it with the arsenate of lead and applying 

 at the same time. 



Whatever material is used, do your work as thoroughly as 

 possible. If you buy the best material that you can obtain 

 you need -not fear any injury. Spray all kinds of fruit trees 

 for the scale in the winter. Spray all kinds of fruit trees 

 with the exception of the peach for the foliage and fruit in- 

 sects, but never spray peach trees with arsenate of lead or 

 bordeaux mixture. Do not spray your peach trees with sol- 

 uble oil when the temperature is much below 40 degrees 

 Fahrenheit. If the peach trees are sprayed during a warm 

 day, no injury will result from cold weather afterward, and 

 it is possible that the injury may come from the cold water 

 rather than from the oil. The other fruit trees can be
