in Ohio in 1941 was 112,275,000
board feet while the cut during the same year was slightly over 3
million board feet.

~Pests~--The most serious pest is the walnut datana whose larvae eat the
leaves. Other leaf-eating insects include the fall web worm and the
hickory-horned devil. Several leaf spot diseases have attacked the
leaves, also causing early defoliation. Leaf eating insects and leaf
spot disease can be controlled by the application of one spray in June.
This is composed of three pounds of arsenate of lead, ten pounds of
powered Bordeaux mixture, and a good sticker in one hundred gallons of
water.

~Selected Varieties~--Walnut trees vary greatly in the type of nut they
produce. The most popular strains have been selected for propagation.
The varieties which have been propagated by nurserymen are the Thomas,
Ohio, Stabler, Ten Eyck, and Elmer Myers. Since the cost of grafted nut
trees is rather high, many people are interested in planting the nuts of
the better varieties for large scale planting. Seedling trees may be
raised easily by anyone, whereas much skill and practice are required to
produce grafted and budded trees. The degree to which the desirable
characteristics of selected varieties are transmitted through seed is
now being studied by the Ohio Agricultural Experiment Station.

A list of commercial nut nurseries may be obtained by writing to Miss
Mildred Jones, Secretary, Northern Nut Growers Association, Lancaster,
Pennsylvania.
