Embrapa presents new control for black sigatoka
Brazilian researchers have presented a “promising cheap and effective” control against the banana disease, black sigatoka ( Mycosphaerella fijiensis). Rather than 52 annual fungicide applications, only three low-dose applications per cycle are required for the best results, the Brazilian agricultural research corporation, the Embrapa, says. It recommends 2 ml of flutriafol-based fungicides per plant for each application, and 1 ml of azoxystrobin, allowing marketing to be directed at small-scale farmers. The applications should be directed to specific areas near the top of the plant, below the leaves. The corporation advises using a syringe to direct applications. The syringe applications also avoid drift to other plants. The Embrapa studies leading to these results started in 2003.
