تأثير بعض عوامل الأستحثاث الكيميائية في خفض أصابة نبات الذرة الصفراء بالفطر Fusarium verticillioides

Abstract EN

This study was aimed to determine the effect of some inducing factors (Algibberellin, Alsalicylic, zinc sulphate and the pesticide Chinosol ) in reducing infection maize plant disease seed rot and seedling blight caused by fungus Fusarium verticillioides.

Results of the study showed that the effect of different concentrations of some of the factors forcing (Alsalicylic, Algibberellin and zinc sulphate) in the inhibition of different isolates of Alaftralmamrd F.

verticillioides which showed that all concentrations have a significant impact on the growth of isolates fungus F.

verticillioides, where the treatment of zinc sulfate has achieved the highest rate to discourage isolates fungus F.

verticillioides reaching 80.74% compared with Bamaammelta Alsalicylic and Algibberellin reatments which reached a 71.48, 50.57% respectively.

The results also showed that the pesticide Chinosol damped spinning fungal growth for all isolates fungus F.

verticillioides in the center Zorai daunting entirely reached 100% at all concentrations tested.

Field experiment by measuring the growth indicators to plant maize has shown that marinating forcing factors (Alsalicylic, Algibberellin and zinc sulphate) has reduced the negative impact of the fungus pathogen F.

verticillioides through high percentage of seed germination as it outperformed the treatment of drenching where this ratio rose from 75.00% in contaminated soil fungus Fusarium verticillioides to 100.00, 91.67 and 91.67%, respectively.

When we added zinc sulfate, Alsalicylic and Algibberellin respectively.

It was found that the best treatment in terms of plant height, number of leaves and chlorophyll and the weight ratio of (100) Bean excelled treatment Algibberellin morally on all transactions.
