Several years' experience in controlling the bug ( Lygus communis 
Knight) on apples with nicotine sulphate has led the author to conclude 
that sprays do not give such good results as 5 percent dusts (2 percent 
actual nicotine) under Nova Scotia conditions. The potato aphid ( Macro - 
siphum gei Koch) as well as other sucking insects on low-growing crops 
can "be completely controlled "by means of a dust of 4 percent nicotine 
sulphate used in conjunction with a canvas trailer.

The application of a dust containing nicotine gave satisfactory 
results, and the affected plants subsequently made good growth.

A 4 percent nicotine dust killed 85 percent of the tarnished 
plant bugs ( Lygus pratensis L.) and 90 percent of the stink bugs 
( Euschistus servus Say.) treated. A 5 percent dust killed 100 percent 
of the former bugs. A nicotine sulphate spray (1:200) plus fish-oil 
soap (2 lb. in 50 gal.) killed 92 percent of the tarnished plant bugs 
(p. 273) . No complete control of these insects is at present available, 
and the insecticide treatments are unsatisfactory (p. 2 75).

Nicotine dust consisting of 2 percent nicotine sulphate dust 
with dolomite as a carrier, as well as 2 percent nicotine sulphate 
dust with hydrated lime as a carrier, proved as satisfactory as 
nicotine sprays in the control of redbugs in the petal spray.

Pyrethrum dust, with or without an equal quantity of 2.5 percent 
nicotine dust, gave the most promising results, killing 8 out of 16 and 
4 out of 10 respectively.
