een worms sometimes called tomato worms or tobacco worms as they feed teed about equally well on on both plants They are the larvae or r young of ot large sphinx moths of two species which are very similar In habits and distribution These Insects produce two broods and nd when they begin to mature they cut all the leaves from tomato plants Growers should be on the lookout for tor the first as well as the second second brood They appear at vanus various van vari ous us times according to the locality Control Hand lland Hand picking can be i practiced but It takes an on experienced eye to detect these thes worms when they ore are at nt rest When feeding they are more easily seen and can be destroyed readily A single application of ot lead lead arsenate at the e usual rate will de del deI destroy I stroy them even though crudely ap plied Those which eat the poison polson first will be found dead the following day ay The remainder will be found on the second or third day Tomato Tho

fruit and destroying Its market value Control Lead Lead arsenate 2 pounds to to 23 2 gallons of ot water applied two or three times will keep the Insect under partial control As long as sweet corn Is
