PECAN 
TREES 
There are many insects and diseases attacking 
pecan trees. Below are listed the most common for 
this area, accompanied by methods of treatment 
suggested by the U. S. Department of Agriculture 
Farmer’s Bulletin No. 1829. 
NUT CASE BORER: Attack the young shoots in 
in the spring by boring into them. After about 
<wo weeks they pupate and later transform to 
brownish moths about 5/8’s inch across the wings. 
This moth appears about the time the nuts begin 
to form and proceed to lay their eggs about the 
ends of tiny nuts. Spray when nuts are small, 
shortly after first generation of eggs begin to 
hatch, is most effective method of control. 13 ounces 
of nicotine sulphate and 3 quarts of summer oil 
emulsion of 100 gallons of water is the recom- 
mended spray. 
BORERS: Run-down, undernourisned trees are 
perfect victims for borers. The two most common 
ones are the shot-hole borer and flat-head apple 
borer. There is no satisfactory control for the 
shot-hole borer and the same applies to the flat- 
head apple borer. However, the grub should be 
killed in the gallery under the bark with a sharp 
knife and the wood painted with a pruning com- 
pound or tree paint. The trunks on small trees 
should be wrapped with paper from the ground to 
the branches. Keep trees well fertilized and healthy. 
TWIG GIRDLER: A serious pest in this area. 
The only method of control is to gather up the 
broken branches and burn them. The girdler lays 
its eggs in the end of the broken branch, and 
timely destruction of these eggs prevents later in- 
festation. Burn girdled branches hanging in the 
trees. 
LEAF CASEBEARER: The moth appears gener- 
ally in May, and lays eggs underneath the leaves.

leaves, causing a serious loss of vitality nn the tree. 
Spray with 2 pounds calcium arsenate and 8 pounds 
bordeaux mixture to 100 gallons of water. Spray 
early in July. 
ROSETTE: Usually attacks pecan trees growing 
on calcareous soils, sandy loams, loamy sand and 
deep, sandy soils deficient in organic matter. The 
Stuart, Van Deman, Frotcher and Delmas are per- 
haps the most susceptible. The disease is first 
indicated by slight yellow mottling of the leaves, 
particularly in the tops of the trees. Later the 
leaves become narrowed and crinkled, with reddish 
brown areas or perforations between the leaves. 
New growth is checked, the internodes shortened and 
the leaves are bunched together. Control with zinc 
sulphate. Two to four pounds of zine sulphate ta 
100 gallons of water applied as a spray to the 
foliage as the trees begin to leaf out in the spring. 
Wet all leaves thoroughly. Apply zinc sulphate 
by broadcasting evenly from the trunk to beyond 
the limb areas. On light soils use % pound for 
n of diameter of tree trunk. On heavy alkaline 
ls use 1 to 2 pounds as above.
