Red Spider and Cyclamen Mites and other 
Mites 
“Rotenone appears at present to be the 
most promising spray material to try against 
the pallid (Cyclamen) mite and is effective 
also against aphids, thrips, and red spider 
mite. Since finely ground sulfur is also ef¬ 
fective against exposed mites, better results 
may be secured by either combining a wet- 
table sulfur with the rotenone spray or fol¬ 
lowing each spray treatment with a light 
dusting of dusting sulfur.”—Delphinium So¬ 
ciety Year Book, 1939.

Pyrote—An excellent general pur¬ 
pose spray. Pyrote combines the 
killing power of both pyrethrum

the plants are young, the ef¬ 
fective control of the most 
common insects may be ex¬ 
pected. Pyrote is non-poison¬

will not injure the tenderest 
foliage, does not discolor, con¬ 
tains its own spreader, mixes 
easily, and is economical. It is 
equally effective in the green¬ 
house, in the flower and vege¬ 
table gardens, on shrubs, and 
for fruit and shade trees. It is an excellent sub¬
