VEGETABLE, GROWING IN NEW SOUTH WALES. 131 



About 1,000 cabbage plants can be dusted in an hour, and one kerosene 

 tinful of the mixture will do 400 plants. 



For slugs and snails some growers prefer to use slaked lime by itself and to 

 sprinkle it around the plants. Others mix tobacco dust with five times its 

 quantity of ashes and dust the plants with the mixture. (See also page 124). 



Sulphur Powder. Flowers of sulphur are used to control mildews. Tt 

 should be applied by means of bellows in the early spring, and at any time 

 later in the season when the disease is observed. The early morning is 

 generally the best time for the application. 



Poisoned bait, consisting of 1 Ib. Paris green or commercial arsenic to 24 Ib. 

 bran, 3 oz. salt, and 3 quarts of water can be recommended for most cut- 

 worms. This bait when mixed makes a crumbly mash which is scattered 

 lightly throughout the crop or along the rows of seedlings at the rate of 50 

 to 75 Ib. per acre. Another bait is green corn, lucerne or potato tops cut in 

 the chaff-cutter, and dipped in Paris green water. Such treated areas, of 

 course, should not be open to stock. A straight-walled deep furrow ploughed 

 in front of advancing cutworms arrests thousands, which fall into the trench 

 where they accumulate and can be sprayed with oil sprays or crushed with a 

 heavy log drawn along the furrow. 



Fumigation is used as a means of destroying the moths, grubs, and larvte 

 of the potato moth in stored potatoes, and for cleansing the seed of such 

 crops as peas, beans, &c., which are attacked by weevil. 



The seed to be treated should be placed in a barrel or bin, or better 

 still in an iron water tank, and the lid adjusted so that it can be weighted 

 down and made airtight. A ring of rubber gas tubing can be often success- 

 fully used for the purpose, or if this is not possible, cloth of close texture 

 should be substituted. 



Better results are obtained if the operation is carried out in the spring or 

 summer, than in the winter ; the temperature should be about 70 deg. Fah. 



The liquid carbon bisulphide, which is used fpr this purpose, is placed in a 

 saucer or dish on top of the seed in the barrel, and the top securely fastened 

 down. This liquid readily becomes a gas which is heavier than air, and the 

 fumes sink down through the seed ; hence the reason for placing it on top of 

 the seed. 



For a well-sealed tank or cask, at a temperature of 70 deg. Fah., use 

 1 fluid oz. of carbon bisulphide to every 16 cubic feet of space, and if the 

 temperature is below 65 deg. Fah. or, where the vessel is not perfectly 

 airtight use 1J fluid oz. 



One teaspoonful is more than sufficient for a kerosene tin of seed. 



The seed should be left in the gas for from 20 to 24 hours, never more 

 than 30 hours, and at the end of that' time the fumes should be dislodged by 

 srirring the grain.
