 causing it to ripen prematurely.

 Poultry. 



GREEN LEAF-HOPPER. See under CURRANT. 



Grape. GRAPE BERRY- WORM (Polychrosis viteana). Larva, about one- 

 fourth inch long, feeding in the berry, often securing three or four 

 together by a web ; two broods. 



Remedy. Spray with arsenate of lead before blossoms open. 

 Repeat after blooming and again in early July. Destroy wormy 

 berries in August. 



GRAPE-CURCULIO (Craponius incequalis). Larva, small, white, 

 with a brownish head. Infests the grape in June and July, 

 causing a little black hole in the skin and a discoloration of 

 the berry immediately around it. The adult is a grayish brown 

 snout-beetle, about one-tenth inch long. 



Treatment. Spray with arsenate of lead while the beetles 

 are feeding on the leaves. The beetle may be jarred down on 

 sheets, as with the plum-curculio. Bagging the clusters. 



GRAPE-SLUG or SAW-FLY (Selandria vitis) . Larva about one-half 

 inch long, yellowish green with black points, feeding upon the 

 leaves ; two broods.

GRAPE ROOT- WORM (Fidia viticida). The small white grubs 

 feed upon the roots, often killing the vines in a few years. The 

 adults are small grayish-brown beetles that eat peculiar chain-like 

 holes in the leaves during July and August. Cultivate thoroughly 

 in June, especially close around the vines to kill the pupae in the 

 soil. At the first appearance of the beetles spray the plants with 

 arsenate of lead at the rate of 8 or 10 pounds to 100 gallons of 

 water, to which should be added 1 gallon of molasses (Geneva 

 Experiment Station).
