Utilização de azoxistrobina no controle da antracnose da mangueira
[The use of azoxystrobin in the control of mango anthracnosis]
Fitopatologia Brasileira 29 (2), 193-196
Abstract: Anthracnosis is a serious disease that limits the production of healthy and marketable mangos (Mangifera indica). Due to the serious nature of this disease, a study was undertaken to test the efficacy of azoxystrobin as compared to different fungicides commonly utilized for the control of the disease in mangos. The fungicides were applied to mango plants of cv. Tommy Atkins through a ten-treatment experiment with four, three-plant replicates. The products tested were azoxystrobin WG (50; 75; 100 mg.l-1 a.i.) plus nonylphenol ethoxylate (0.05%); azoxystrobin (75 mg.l-1 a.i.) + paraffin mineral oil (0.2 and 0,5%), chlorothalonil WP (1240 mg.l-1 a.i.); benomyl WP (500 mg.l-1 a.i.); copper oxychloride WP (2350 mg.l-1 a.i.); chlorothalonil/azoxystrobin (1240/75 mg.l-1 a.i.), alternating these products at each application; and an unsprayed control. A total of six applications were performed at 15 days intervals, the first one performed at panicle plain flux. Fruits were evaluated 20 days after the last application, in 25 fruits/plant collections, totaling 1,000 fruits, which were conditioned in cardboard boxes and stored at ambient temperature during 15 days. The fruits were evaluated based on the incidence and severity of injury to them. The data were analyzed through the non-parametric Kruskal-Wallis test. There were no significant differences between the chemicals applied; except between these and the control. However, the treatment with azoxystrobin (75 mg.l-1 a.i.) + paraffin mineral oil in (0.5%) was the one that exhibited the least incidence of the disease.
