Tobacco dust is not reliable, because it soon loses its strength and does not completely cover the plant. In the previous article on the midge I gave a formula for using nicotine, with advice to use it strong enough to burn the foliage. It is difficult to state what proportion this requires. In the winter, when ventilators are down tight and there is little circulation of air, considerably less nicotine is needed than in the summer, when the venti- lators are open day and night. I have also found a great deal of difference in the chemical action of water. Alkali or lime rock water, or water from wells, demands almost twice as much nicotine as water from lakes, rivers or ponds. One grower situated just across the road from another, but having a differ- ent source of water supply, has to use just twice as much nicotine as his neigh- bor. The latter uses pond water, while the former uses well water. For this reason I can only say, use your nicotine spray strong enough to burn the foliage. By nicotine spray I mean your favorite brand, whatever it may be. Successful Formula. Here I will repeat what I regard as the most successful midge destroyer. If you have a better one that is absolutely dependable, kindly send it in for publi- cation. My formula is nicotine in liquid spray form strong enough to burn the foliage (add enough y
