on the ground, although it is not easy to see the caterpillar 

 itself as it rests motionless on a stem, its colors blending with 

 the green of the foliage and the light stripes on its side suggesting 

 the veins on the underside of the leaves. In the small garden 

 or in larger fields where the caterpillars are not numerous, 

 hand-picking is the cheapest and most practical means of 

 control. When the worms appear in considerable abundance, 

 spraying with paris green or arsenate of lead will give good 

 results. Arsenate of lead is to be preferred on tomatoes because 

 it is not so likely to burn the foliage. It is usually used at the 

 rate of 2 or 3 pounds of the paste to 50 gallons of water. The 

 first application should be made while the caterpillars are still 

 small because they are then killed more quickly and by a smaller 

 quantity of the poison than later. There is no danger . in 

 spraying tomatoes until the fruit is half grown, and some 

 growers apply paris green till within ten days of picking. The 

 arsenate of lead may be applied in the form of a dust diluted 

 with some inert material.
