Mason City G I o b e 22 Globe-Gazette Photos BORERS GOT SOME—Corn borers don't actually eat corn but they make a difference in yield nevertheless. Here H D. Gaspers, Swaledale, is shown with sacks of corn gathered from 51 hills each, one plot sprayed with DD1 and the other unsprayed. ^ Caspers Picked Nearly 40% More Corn Where Sprayed Herman D. Caspers of Swale--* dale has found that it pays to spray with DDT to control corn borers. He received a higher yield from fewer stalks in the corn he sprayed and there were only half as many ears on the ground and very few stalks broken over before the storm. Caspers farms 400 acres and 150 acres was in corn this year. He was doubtful about the value of spraying to control corn borers but he wanted to see for himself so he sprayed 33 acres. From the 33 acres he sprayed, the yield was 73.2 pounds of corn for 51 hills and from the unsprayed field he picked only 53 pounds from 51 hills. Despite the windstorm, County Extension Director Marion E, Olson is holding a field day at the Caspers farm Thursday Farm Bureau fieldman. from 11 a. m. to 1:30 p. m. so that interested farmers can inspect the fields. The lodging comparison may not be as good since the storm, he said, but farmers will be able to see how much borers added to the wind damage. The Caspers farm is on the southeast edge of Swaledale. There was an egg mass count of 300 on the Caspers farm when he sprayed the first time on 1 June 21. Eight days later he had more than 50 egg masses per 100 plants so he sprayed a second time. Foth times he used about 2 pounds of actual DDDT per acre. He used the 25 per cent concentration, putting 22 gallons of the actual mixture on the 33 acres. When a borer count was made this past week on the sprayed field there was a very small per. cent of stalks broken off, while on the unsprayed field 20 per cent of the stalks were broken, according to Olson who did the statistical sampling. There was an average of one borer for every 2 stalks on the sprayed field and an average of 6' live borers per stalk on tne unsprayed. Other fields have been checked and there was a difference in every field that would have paid several hundred per cent on spraying. Corn on the treated field weighed 56 pounds per bushel and on the untreated it weighed 55 pounds. Corn on the unsprayed field could not have graded better than number 3 on account of damaged kernels, while that on the sprayed field could have graded no. 1 or 2. USED B. ALLIS CHALMERS NEW C.
