Gesarol AK-20 spray in repeated applications caused no perceptible 
injury to apple foliage or fruit.— Conklin (116 ) ♦ 
Aside from some browning of the foliage late in the fall, there 
wa6 no apparent injury from any of the WT sprays or dusts tested.- 
Anon. (17) • 
Citrus. In none of the field experiments made with DDT, either 
dissolved in oil or used in other ways, was the slightest indication 
found of injury to the trees* Pour navel orange and four lemon trees 
were sprayed seven times from March to December 1944 with each of the 
following treatments! (l) 1 3/4 percent of light medium oil, (2) 1 3/4 
percent of light medium oil with 4 percent of DDT in the oil, (3) 3 per- 
cent of kerosene, (4) 3 percent of kerosene with 4 percent of DDT in 
the kerosene, and (5) Gesarol AK-20 at 10 pounds to 100 gallons of 
water* The repeated light medium oil sprays caused serious defoliation 
and dead wood on the 14-year old orange trees but little damage to the 
5-year old lemon trees* In neither case, however, was the damage 
greater on the oil-DDT- sprayed trees than on the oil-sprayed trees* 
Neither the kerosene nor the kerosene-DDT caused any discernible in- 
jury to either the orange or the lemon trees* Likewise, no injury to 
the bark below the soil line was observed when the soil was removed 
and the trunks were scraped on February 8, 1945» The repeated treat- 
ments with Gesarol AK-20 also caused no deleterious effects*— Ebeling 
(142)* 
Corn . A 3-percent DDT dust interfered with growth of the corn.— 
N. J. Agr. Expt. Sta. (275 ). 
Grape . DDT-pyrophyllite (20-80) was used at the rate of 1 pound 
of DDT in 100 gallons of water plus J- pound of soybean flour. The 
spray was applied at the rate of 200 gallons per acre on July 15 and 
27* The entire vineyard was treated with the DDT spray on August 9* 
Most of the spray was directed toward the upper surface of the leaves 
to avoid spraying the fruit. There was no injury from DDT sprays to 
foliage.— N* J* Agr. Expt. Sta. (275). 
Peach . Three applications of 2 pounds of Gesarol A-20 per 100 
gallons caused no damage to peach foliage.— Underhi 11 (349 ) » 
Pear. Dormant misoible oil containing IDT, applied as a dormant 
spray to give 5.12 ounces of DDT per 100 gallons, caused no adverse 
effect on buds, bloom, foliage, yield, or fruit size.— Cleveland (114). 
Potato . No harmful effects on foliage were noted. In one test 
DDT-treated potato plants appeared more vigorous, larger, and darker 
green than those treated with other materials. Early blight lesions 
were not significantly reduced with DDT. — Tate et al. (342).
