Cost/ Benefit analysis of dusts seed dresing on three genotypes of corn (Zea mays L.) with difference resistance to common smut disease on corn
AbstractThe economic:cost/ benefit analysis of seeds dresing with two fungicides(vitavax and Divideend) with three genotypes of corn Zea mays L.possising difference resistance to common smut disease on corn caused by Ustilago maydis (Shahad highly.IPA5012, moderate and Neelum susceptable), Factorial Experimenta in RCBD design was used. The cost , benefin and the ratio between them was calculated for ech fungicide treatment. Results midcated economic benefic for all fungicides even with highly resistant caltivar (2100dha)whit vitavax (2400dha).Result were also indicated that the benefit of the first fungecids was(4513 D) compard to (2726 D)for the second. The ratio of susceptible to resistance genotype treated with fungicide was very switable 1:3.5 which indicate that the first fungecides was very switable for seed dressing for all genotype tested.
