Abstract: A study realized during two consecutive years at Mimetala and Nkometou, permitted to evaluate the antifungal potential of aqueous extract of neem seeds (AENS) on the Asian rust of soybean development. Varieties of soybean used, were a locale, TGX1835-10E and TGX1910-14E. A system of completely randomized blocks was used containing five treatments: T0 (control), T1, T2, T3 (consisting of 25, 50, 100 g/l of extract respectively) and T5 (treated with Plantineb 80wp). The growth and disease parameters, yield were evaluated under the influence of different treatments. During the two campaigns, growth parameters varied significantly and proportionately for different doses of extracts, T4 having the largest values followed by T3at Mimetala. Those parameters were high on locale and TGX1910-14E varieties during the two campaigns. In 2015 as in 2016, TGX1835-10E was the most attacked by the disease in the two sites. Its incidence in the controlwas 100% and 80% in 2015 and 97.5 and 75% in 2016 respectively at Mimetala and Nkometou. TGX 1910-14E was the least attacked with an incidence in the control of 47.5% and 45%, and 5% in T3 and T4respectively in 2015 and 2016. Disease was most severe at Nkometou on local (67%)and least at Mimetala on TGX 1910-14E (22.3%) in the control. The yielding was lightly high in 2016 than 2015 and high values were obtained at Mimetala in T4 and T3. Results suggest that AENSis a biocidal substance with an antifungal activity and should be applied at high doses.
