78 ARTICLE MAY 2019 were released on them. In the 6-month protective ef- fect tests, the drug was sprayed on the maize but the major insects were left on the product 1, 2, 3, 4, 5, and 6 months after spraying the drug on the product. After insects were released on medicated products, six days following the release of S. Oryzae and two days after P. İnterpunctella, the death rates were calculated with the help of 2 milimeter sieve. 3. RESULTS 3.1. Results from tests conducted with Sitophilus oryzae When the percentage impact value obtained in the count results which were carried out after 24 hours and 1 and 6 months following medicating maize against rice germ (S. Oryzae) to determine the biological effe- ctiveness of K-Obiol EC 25 preparation were reviewed, the application dose (F5,168 = 405.94, P<0.0001) and the duration of waiting of the medicated product (F6,168 = 153.75, P<0.0001) have important effe- ct on the percentage impact value of drug. While the percentage effectiveness of K-Obiol EC 25 preparation on 20 and 30 ml drug + 1 liter water / 1 ton product dosage at 24 hours and all months is found to be 100 percent, its percentage effectiveness on 15 ml drug + 1 liter water / 1 ton product at 24 hours and 1., 2., 3., 4., and 5. month is found to be 100 percent but decreased to 92 percent in the 6th month. Also, at the concentration of 10 ml drug + 1 liter water / 1 ton product, which is recommended concentration, the percentage impact is 100 percent at 24 hours and 1st month but it decreased to 99 percent in 2nd and 3rd month and decreased further to 97, 88, and 82 percent at 4th, 5th, and 6th respectively. In 5 ml drug + 1 liter water / 1 ton product concentration, no application has 100 percent impact. (Figure 2). 3.2. Results from tests conducted with Plodia interpunctella When the percentage impact value obtained in the count results which were carried out after 24 hours and 1 and 6 months following medicating maize aga- inst dried fruit moth (P. interpunctella) to determine the biological effectiveness of K-Obiol EC 25 preparation were reviewed, the application dose (F5,168 = 188.78, P<0.0001) and the duration of waiting of the medica- ted product (F6,168 = 131.34, P<0.0001) have im- portant effect on the percentage impact value of drug. While the percentage effectiveness of K-Obiol EC 25 preparation on 20 and 30 ml drug + 1 liter water / 1 ton product dosage at 24 hours and all months is found to be 100 percent, its percentage effectiveness on 15 ml drug + 1 liter water / 1 ton product at 24 hours and 1. and 2. month is found to be 100. At the concentrati- on of 10 ml drug + 1 liter water / 1 ton product, which is recommended concentration, the percentage impact is 100 percent at 24 hours and 1st month but it decrea- sed to 97, 93, 90, 84, and 80 percent in 2nd, 3rd, 4th, 5th, and 6th month respectively. In 5 ml drug + 1 liter water / 1 ton product concentration, tests after one day drying have 100 percent impact (Figure 3). 4. DISCUSSION The analysis of variance results applied on the per- centage impact value obtained in the count results which were carried out after 24 hours and 1 and 6 months following medicating maize against rice germ (S. oryzae) and dried fruit moth (P. interpunctella) to determine the biological effectiveness of K-Obiol EC 25 preparation showed that K-Obiol EC 25’s appli- cation dosage and the waiting period of medicated Figure 2.
