GARDEN GUIDE 



White Grub 



GRASS 



White Grubs: These 

 are the larvae of June 

 beetles and when nearly 

 mature and abundant in 

 the soil cause much dam- 

 age, especially in dry 

 seasons, by eating off the 

 roots of grass, corn, pota- 

 toes, strawberries, etc. 

 Plow in Fall to expose in- 

 sects. Harrow very thor- 

 oughly before planting. 



Army- worm: Occasional- 

 ly, brown, striped caterpillars 

 are so abundant as to strip 

 the leaves and heads from 

 grass and grain during July; 

 they move like armies from 

 one field to another, some- 

 times doing great damage. 

 Use poisoned bran mash. 

 Plow deep furrows across the 

 line of march, with steep side 

 barring their progress. 

 Sprinkle worms with kerosene. 

 Spray strips of grass or grain 

 with lead arsenate to protect 

 the fields beyond. 



Fall Army-worm: 



Attacks lawns and millet in 

 September, like preceding, but 

 does not migrate in such large 

 numbers. Same remedies 

 Army Worm apply. Plow in late Fall. 



HICKORY 



Walnut Caterpillar: See Walnut. 



Fall Web-worm : See Pear. 



Hickory Borer: Larvae tunnel in solid 

 wood of trunk. The burrows may be 

 found by the sawdust ejected. Inject car- 

 bon disulphide into the burrow and close 

 the entrance. 



Hickory Tussock Moth: White and 

 black hairy caterpillars feed upon the leaves 

 in late Summer. Spray with lead arsenate. 



Hickory Bark Beetle: Small black 

 beetles breed under the bark, and the 

 galleries soon girdle the tree. T?he adults 

 emerge through small round "shot-holes" 

 in the bark. Beetles also feed at base of 

 leaves, causing them to break off and fall in 

 Midsummer- Badly infested trees should 

 be removed before May, and either burned 

 or else the bark removed. Spray healthy 

 trees about June ist with strong lead 

 arsenate with nicotine solution added. 



Nut Weevils: Larvae infest the fruit or 

 nuts. See Chestnut. ^ 



Hickory Gall Aphid : Curious galls on 

 the leaf stems often cause the leaves to fall 

 in Midsummer. Galls contain large num- 

 bers of aphids. Spray with nicotine solu- 

 tion just as new growth starts in Spring. 



HOP 



Hop Aphid : Green aphids sucking sap 

 from the under leaf-surface. Spray with 

 kerosene emulsion. 



HORSE CHESTNUT 



White- 

 marked Tussock 

 Moth: Black and 

 yellow.red-headed 

 hairy caterpillars, 

 each bearing four 

 upright tufts of 

 white hairs, de- 

 vour the leaves. 

 Spray with lead 

 arsenate. 



White-marked Tussock 

 Moth 



IRIS 



Iris Root Borer : A larva tunnels in the 

 root stocks, injuring many plants. Destroy 

 infested root stocks. Burn over Iris beds 

 in Winter to destroy the eggs. 



JUNIPER 



Juniper Web- worm: Small brown 

 caterpillars feed upon the leaves which 

 they web together. Spray with lead 

 arsenate. 



LARCH 



Larch Sawfly: Larvae defoliate trees in 

 Midsummer. Spray with lead arsenate. 



Woolly Aphid : White cottony tufts on 

 bark and at the leaf whorls. Spray with 

 kerosene emulsion. 



LETTUCE 

 Aphid or Green Fly: Sucks sap from 

 the leaves. Spray with soap and water or 

 fumigate beds with tobacco. 



LILAC 



Lilac Borer: A white larva tunnels in 

 the twigs. Cut and burn infested twigs. 

 Oyster-shell Scale : See Apple- 

 San Jose Scale: See Peach. 



LILY 



Stalk Borer: See Dahlia. 



Aphid: Yellow aphids with red mark- 

 ings suck the sap from under side of leaves. 

 Spray with nicotine solution.
