Abstract
Two experiments were carried out in guava orchards cv. 'Paluma' at Monte Alto and Vista Alegre do Alto/SP. In Experiment 1 it was used copper fungicides applied alone and in combination with mancozeb to evaluate the effect of phytotoxicity on floral buds and guava fruits in three developmental stages. In Experiment 2 it was used the same fungicides used in Experiment 1, plus a treatment with tebucunazole in order to evaluate the rust control. In Experiment 1 none of the fungicides tested caused phytotoxicity symptoms and abortion of fruits less than 15 mm in diameter. The fungicides caused higher phytotoxicity in fruits between 25 and 35 mm but not in fruits larger than 40 mm diameter. Copper fungicides combined with mancozeb lead to a slight toxicity, but when applied the mancozeb alone did not lead to phytotoxicity sympton. In The Experiment 2, it was observed that copper fungicides applied alone were efficient to control rust as well as the combination of mancozeb and cuprous oxide or hydroxide and the fungicide tebuconazole.
Zwei Versuche wurden in Guavenplantagen der Sorte 'Paluma' in Monte Alto und Vista Alegre do Alto/SP durchgeführt. In Versuch 1 wurden Kupferfungizide allein sowie in Kombination mit Mancozeb eingesetzt, um die phytotoxische Wirkung auf Blütenknospen und Guavenfrüchte in drei Entwicklungsstadien zu untersuchen. In Versuch 2 wurden dieselben Fungizide wie in Versuch 1 verwendet, ergänzt um eine Behandlung mit Tebuconazol zur Bewertung der Rostbekämpfung. In Versuch 1 verursachte keines der getesteten Fungizide Phytotoxizitätssymptome oder den Abwurf von Früchten mit einem Durchmesser von weniger als 15 mm. Die Fungizide führten bei Früchten zwischen 25 und 35 mm zu einer höheren Phytotoxizität, nicht jedoch bei Früchten mit einem Durchmesser von mehr als 40 mm. Kupferfungizide in Kombination mit Mancozeb führten zu einer leichten Toxizität, während die alleinige Ausbringung von Mancozeb zu keinen Phytotoxizitätssymptomen führte. In Versuch 2 wurde beobachtet, dass allein ausgebrachte Kupferfungizide den Rost ebenso wirksam bekämpften wie die Kombination aus Mancozeb und Kupfer(I)-oxid oder Kupferhydroxid sowie das Fungizid Tebuconazol.
