Treatments correspondend to a single application on 01/10/89 of: A) check; B) juvenoid flucycloxuron, 40 cm³; C) bromopropilate 65 cm³; D) quinomethionate + sulphur 200 cm³; E) quinomethionate + sulphur 250 cm³; F) fonnetanate 22,5 g; G) formetanate 31,5 g. The quantities are of commercial formulations in 100 liters of water. Each tree received 10 liters of the mixtures. Avaliations were made before spraying and 6, 20, 36, 50 and 68 days after the application. The most effective results in the last three avaliations were obtained with treatments F, G and C.
