Role of Cultivars , Growth Regulators and Biocides on the Incidence of Mango Malformation in Egypt [ READ ]
Azza M. K. Azmy
Isolation trials from malformed mango inflorescences frequenty yielded Fusaraium mangiferae .Seven local mango cultivars, i.e. Ewasy, Fagri klan, Hendy , Hendy Sennara , Keitt, Kent, and Saddeka of 10 years old were evaluated fot their ability to the natural infected by malformation disease during 2012 growing season. Data revealed that Saddeka cv. followed by Ewasy cv. were the most susceptible ones to the disease incidence and Keitt was the lowest affected one. The effect of three commercial growth regulators, i.e. Agrotone (NAA), Berelex (GA3), Cultar (paclobutrazol) and four biocides, i.e. AQ10 (Ampelomyces quisqualis), Bio-ARC (Bacillus megaterium) , Bio-Zeid (Trichoderma album ) and Blight Stop (Trichoderma spp.), on the incidence of mango malformation was evaluated in the field under the natural infection by the disease during 2012 /2013 and 2013/ 2014 growing seasons. Results indicated that the two growth regulators ,i.e. Cultar and Agrotone and the biocide Bio-Zeid were the most effective treatments in reducing the disease and increasing the produced fruit yield than the other treatments when each of them was used alone. However, the combination treatment between the growth regulator Cultar and the biocide Bio-Zeid was the most efficient treatment in this regard.
