has a very killing effect on the immature 

 stages, especially the larval stages, but 

 does not have so great a killing effect on 

 the adults. For this general field con- 

 dition we have found the 2\'/( to 3*^ free 

 nicotine, or which is usually classed as 

 6% or l''r Black Leaf 40, formula, entire- 

 ly satisfactory. However, this merely 

 controls the rapid multiplication of the 

 pest, and does not entirely eliminate it 

 as the stronger formula does on the seed 

 beds, or original infestation center.". 



"4. We have used both powder guns 

 of the Niagara Sprayer Company, as well 

 as the California Companies, and the Leg- 

 gett Power guns, as well as the high 

 power machines which are used in dusting 

 cotton. By any method it seems that at 

 least 15 lbs. per acre must be used of the 

 dust, and it is easy to figure what the 

 cost will be when the nico dust products 

 range in prices anywhere from 20('- to 40<' 

 per lb. depending upon the strength used. 



"•3. It is very important to consider 

 climatic conditions as the time of dusting. 

 Days calm, when the dust will hold close 

 to the earth and gradually settle as 

 a cloud around the plants, together 

 with clear bright sun, constitute an 

 ideal condition for efficiency. Under 

 those circumstances the killing effect of 

 the weaker formulas is oftentimes as 

 great as secured by the stronger formu- 

 las. However, if the weather .should be 

 cloudy, or damp, or considerable wind 

 blowing- to immediately catch the cloud 

 of nico dust and dissipate it through the 

 air, or keep it moving over the surface of 

 the ground, you cannot get the greatest 

 efficiency. In fact it is not advisable to 

 apply it, under those conditions unless an 

 emergency exists. The more wind, the 

 more moisture in the atmo.sphere, and the 

 less sunshine, the stronger the formula 

 will need to be in order to secure as high 

 a killing effect, as VA weaker formula 

 give, with dry arid conditions and hot sun 

 and an almost perfect calm. 



"6. It is very important that the 

 grower should study the life history so 

 that he is able to recognize the larval 

 stage, the pupal stage, and the adult 

 stage. Of course after the first or 

 -second generation, the generations are in- 

 terlocking. For that reason it is im- 

 portant that the dusting should be done 

 when the bulk of the brood is in the 

 larval, or certainly the pupal stage. The 

 period from the egg to the adult should 

 be understood in the locality where the 

 woik is done, and as a matter of fact the 

 second dusting may as well take place 

 the third or fourth day after, because 

 those which are killed are killed with- 

 in a very few minutes after the applica- 

 tion. However, if the infestation is not 

 serious enough to materially effect the 

 growth of the crop, it might be as well to 

 wait a week or so between applications.
