The trees were sprayed twice in one day with an extract of 
tobacco prepared "by boiling 1 lb. of Nicotiana rustica for 15 minutes 
in 3 gal. of water and diluting with 6 gal. of water. This spray 
destroyed Psylla mali , young caterpillars of Cheimatobia brumata , 
Tortricidae and similar pests.

A soil dressing of 10 parts sulphur and 1 part tobacco dust, 
will repel millipedes. Five parts of sulphur to 1 part of tobacco 
dust applied in the drill rows with the seed of radish and turnip 
gave good results against P horbia brassicae Bouche. Powdered tobacco 
placed about the plants at the time of planting and renewed every 
week has also proved useful. Black Leaf 40 (1:1600) plus 1 lb. whale- 
oil soap to 20 gal. has given excellent results agrdnst the cabbrge 
aphid ( Aphis brassicae L.). Black Leaf 40(1:1600) plus 4 lb. whale- 
oil soap per 100 gal. will control onion thrips ( Thrips tabaci Lind.).

Against the grain thrips ( Suthrips t ritici pro.jectus ) tobacco 
decoctions are very effective. Black Leaf 40 (1 to 1,000 or 1,800) 
and home-made tobacco extract (1 to 10) were also used. The fol- 
lowing mixture was used on tomatoes: 3.5 oz. Black Leaf 40, 2 l/3 
qt. lime- sulphur, and 50 gal. water, with the result that about 75 
percent of the thrips present were killed. Kerosene emulsion, 
soap, tobacco decoctions, and tobacco extracts are recommended 
against tomato aphids ( Megoura solani and Myzus persicae ) , while 
flea-beetles may be checked by dusting with ashes, air-slaked 
lime, or tobacco dust, or by spraying with kerosene emulsion or 
tobacco decoction.
