Show GRASSHOPPER CONTROL By I. M. Hawley, Professor of Zoology Grasshoppers may be unusually abundant this coming summer. In most parts of the state the ground has not frozen deep enough to kill the over-wintering eggs of this pest. As a result we must expect that many small hoppers wi.ll hatch out in lo calities where grasshoppers were abundant last year. It would be wise to think now about using poison bait. Talk it over with your neighbor and with your county agent. Make sure that materials will be availaible. There may be quite a shortage of poison this summer because be-cause of the immense amount that is being used in the southern states for the control of the cotton boll weevil. In experiments carried on in Montana, Mon-tana, the addition of salt to the baits has increased their attractiveness, especially wrhen the grasshoppers are full grown. About five pounds of salt are used to 100 pounds of bran. It has not been tested thoroughly enough under Utah conditions to say definitely whether It should always be .used. Sodium arsenite (weed killer) has been substituted for white "arsenic as the killing agent In some places. In Colorado one pint of sodium arsenite was found to be equal to five pounds of white arsenic (98 per cent). It has the advantage of being easier to mix with the bran, aud when used at the above rate is considerably cheaper. When sawdust ii available the use of half bran and half sawdust has been found to give nerly a good results re-sults as bran alne. Experiments tend to show that sawdust alone is not nearly as good as the half and half mixture When sawdust is used three pounds of this material should replace four pound of bran. We suggest the following formula: A. Bran 20 pounds 15. (White Arsenic 1 pound or Sodium Arsenite (about 3 ounces) 15 pint C. Beet sirup 2 quarts D. Amyl Acetate ounce H. Salt (optional) 1 pound F.
