Abstract
of the wheat grains contaminated with fungi Aspergillus flavus stored and their ability to germinate, was isolated from many fungi associated with grains of wheat, including fungi and A.flavus and A.niger and A.terreus and Penicillium spp and Rhizpusspp The fungus most frequently A.flavus reaching 98% compared to other fungi. And the results indicated that A.flavus showed sensitivity to all concentrations of biocidal tested and the rates varied among themselves morally, as the biocide user, and reached the highest inhibition at the concentration 1 g / l to 100% , 92% at the concentration 0.5 g / l , In addition, the results of statistical analysis to a significant difference in the numbers of bacteria after of seeds, having already overtaken the Treatment of biocide concentration of 10 g / kg seeds contaminated with A.flavus in the numbers of bacteria, amounting to 2.64 × 1012 colony / cloud of the A.flavus in when they arrived, their numbers 0.98 × 1012 configuration console colony / g of the seeds when treated with biocide concentration 5 g / kg seeds. In addition, the results show the efficiency of different concentrations of the biocide is vital in reducing the incidence of fungi A.flavus grain the transaction after the expiration of the storage period of three months, as the percentage of infection fungi 20 , 0% for concentrations of 5 and 10 g / kg, respectively. Differed significantly on the treatment of comparison the rate was 90% Furthermore, it indicated that results of the evaluation activity and the effectiveness of biocidal Thurine wp covered with grains of wheat in the soil after three months of storage on germination percentage after fast A.flavus in the vitality of seeds of wheat stored, which dropped to 39 % while it rose to 98 , 100% in grain treated with biocide concentration of 5 and 10 g / kg seed, respectively. While rates have decreased the proportion of the death of seedling to 2 , 0% in cereals treated with biocide concentration of 5 and 10 g / kg seed in comparison with control, the percentage of the death of seedling to 61%. The indicators of growth and production will assure a significant difference in the rate of increase in plant wheat treatment concentration 5 and 10 g / kg of biocidal. It was the highest height of the plant to concentrate 10 g / kg seed, as was 21.53 cm while the average plant height in the treatment of comparison 12.33 cm The concentration 5 g / kg seed rate of plant height
