A spray of 1 pt. paraffin emulsion, 10 gal. water, and 2 fl. oz 
nicotine is an effective means of controlling the onion thrips (T hrips 
t abaci Lind. ) when it is exposed on the foliage of cucumber. Infestati 
of roses by the rose thrips (T. f uscipennis Hal.) might probably be cor 
.trolled by a. spray cf 2.1b. potash soft soap, 10 gal. soft water and 2 
fl. oz . nicotine. A mixture of 5 oz. nicotine to 1 gal. sulphonated oi 
proved very effective in controlling aphids when used at a dilution of 
1 to 300;

A combination of lime-sulphur (1:40), 1/2 percent penetrol 
and nicotine sulphate (1:3,000) gave 99 percent mortality against 
aphids ( Aphis spiraecola Patch) on Citrus . A 2 percent. dust of 50- 
percent free nicotine with lime as a carrier gave good commercial 
control of melon aphids (Aphis gossypii Glov.) on watermelons in the 
experimental field. "" ~" ~~

In the experimental orchards, combinations of oil and pyre thrum 
or oil and nicotine gave good control of the red spider (Tet ranychus 
tela rius L.) . The last named spray is also effective against the 
codling moth .

One application of lime— sulphur combined with nicotine sulphate 
and emulsified oil caused scorching and defoliation of peaches, but 
did not injure Citrus or apple. A combination of nicotine sulphate 
and miscible white oil commonly recommended for the control of this 
thrips did not prove satisfactory in laboratory tests.
