Powdery Mildew 
Erysiphe cichoracearum DC. 
Frequent in hothouses, but not trouble- 
some elsewhere. Selby recommends a 
dilute copper sulphate solution.

Cladosporium cucumerium Ell & Arth. 
Yields to same treatment as downy mil- 
dew. 
Wilt, Bacterial Wilt 
Bacillus tracheiphillus 
Scattered plants wilt gradually with- 
out evidence of injury. The sap tubes 
are filled with a milky, stringy mass of 
bacteria instead of watery sap. Insects 
are instrumental in spreading the disease. 
Spray with Bordeaux as an insect repel- 
lent. Cut out and destroy all affected 
plants. Practice rotation.

Banded Leaf-Footed Plant Bug 
Leptoglossus phyllopus, Say 
This conspicuous plant bug is a suck- 
ing insect belonging to the same family as 
the squash bug, and is capable of inflict- 
ing similar injury to cucurbits. 
This species is distributed over all the 
Gulf states and many of the neighboring 
states. In North Carolina it is quite 
abundant in some sections. 
Remedies 
In case these bugs should become abund- 
ant, they might be controlled by hand 
picking during the early morning hours 
or about sundown, for at such times they 
are less active than during the heat of the 
day. It has been suggested that the young 
nymphs may be killed with kerosene emul- 
sion. 
The yellow thistle (Carduus spinossissi- 
mus) is their normal food plant, which 
suggests the advisability of keeping these 
plants cut down around gardens or fields 
where cucurbits are grown, or leaving 
only a few plants to serve as traps on 
which the bugs may be killed by spray- 
ing or hand picking. 
Cucumber Flea Beetle 
Epitrix cucumeris, Harr. 
A small, black, oval-shaped, jumping 
beetle, about one-twelfth inch in lengtr, 
sometimes causes quite severe injury by 
eating holes in the foliage of young cu- 
cumbers and other cucurbits. The larva 
of this species is a leaf miner, attacking 
the same plants, but seldom causing much 
damage. 
Remedies 
Wire screens or other mechanical cov- 
ers, poison and repellent sprays, dry 
poison applications, clean culture are 
equuily effective against flea beetles. 
Cutworms 
Various Species 
These may be destroyed by the use of 
poison bait made by mixing bran (40 
parts) with Paris green (one part) moist- 
ened to make a soft mash and then 
sweetened with molasses. 
Distribute around the hills about sun- 
down. | 
Keep the chickens out when this method 
is employed.
