Abstract— The Coffee Leaf Miner – CLM and coffee rust are the main pests and coffee diseases, respectively. One of the rust and CLM handling ways is the preventive use of active ingredients of joint action (fungicide + insecticide) via soil. These products are generally evaluated for their efficiency in the chemical control of pests and diseases; however some of these products may promote a tonic effect by improving plant vigor. Thus, the objective in this work was to verify the influence of the phytosanitary products application on the rust and leaf miner control, on the coffee trees development and production. The assay was installed in Random Block Design – RBD, with twelve treatments T1 – Premier Plus, T2 – Premier Plus and Actara, T3 – Verdadero, T4 – Verdadero and Actara, T5 – Actara, T6 – Actara (Nov/Feb), T7 – Altacor, T8 – Altacor and Actara, T9 – Impact, T10 – Opera, T11- Control and T12 – Practical and three replicates in a Catuaí IAC-144 crop. Number of nodes per branch, productivity, incidence of rust and CLM were evaluated. There was no difference in the coffee trees growth submitted to the application of different phytosanitary products for the control of rust and leaf miner. The application of Thiamethoxan + Cyproconazole in november with a complementary application of Thiamethoxan in february were more efficient for the coffee leaf miner control and provided greater vigor and productivity to the coffee tree.
Keywords— Hemileiavastatrix, Leucopteracoffeela, tonic effect.
