often enough to take care of new growth as soon as it is 

 made. 



The more common and most injurious of orchard and 

 fruit-garden troubles may be identified as follows: 



APPLE SCAB. Dark-green, round, furry spots on the 

 young fruit; worse in cold, rainy seasons. Use Bordeaux 

 mixture or summer lime-sulphur, in spring or summer. 



BLISTER MITE. A spider-like insect causing on the leaves 

 light-green blisters that turn to red or brown; leaves finally 

 drop. Use strong lime-sulphur, miscible oil or kerosene 

 emulsion in early spring. 



BUD MOTH. A light-brown caterpillar about quarter of 

 an inch long, with dark head and legs. Use arsenate of 

 lead or Paris green as buds open. 



TENT CATERPILLAR. Hatches in early spring and grows 

 rapidly, forming tents or nests in the crotches of trees. 

 Wipe out or burn nests. Use arsenate of lead or Paris green 

 in early sprays. 



CANKERWORM. An " inch- worm" that attacks apple 

 trees. Appears in May and June. Use arsenate of lead or 

 Paris green and put bands round the trunks of the trees in 

 April or May. 



CODLING MOTH. A small, dull-brown, night-flying moth; 

 the parent of common apple worms. Except in the north- 

 ern sections there are two broods. Use arsenate of lead in 

 three applications and apply tree bands in July. 



CURCULIO. A small, gray-mottled, shelled beetle with 

 four distinct humps on its back. Attacks practically all 

 orchard trees, drilling holes in newly formed fruits in which 

 the eggs are laid. Arsenate of lead spraying is partly suc- 

 cessful; or the beetles may be shaken down in the morning. 

 A weaker spray must be used on peaches or plums. Lime- 

 sulphur acts as a repellent. 



CURRANT WORM. A small, green, greedy worm that at- 

 tacks gooseberries and currants. Usually appears first on 

 lower leaves. Arsenate of lead or Paris green will kill 

 early broods; use hellebore for later ones. 



ELM-LEAF BEETLE. A dull-yellow beetle about three-
