DESENVOLVIMENTO VEGETATIVO PROVOCADO POR DIFERENTES TIPOS DE FUNGICIDAS E INSETICIDAS APLICADOS VIA SOLO NO CAFEEIRO (Coffea arabica)

Abstract

Coffee production involves the formation of seedlings that need productive, adapted, healthy cultivars, in which the quality of plants is directly influenced from the development of roots to the aerial part. The use of biostimulants in coffee crops aims to provide synthetic, natural or vegetable hormones, which act especially on the plant's physiology. Thus, the objective of the present work is to evaluate the effect of different types of insecticides and fungicides applied via soil on coffee growth. The experiment was set up in a randomized block design (DBC), with 4 treatments and 5 blocks, being: T1 Thiametoxan + Chlorantraniliprole; T2 Flupiradifurone; T3 Triadimenol + Imidacloprid; T4Witness. Thus, in the present work, it was verified that the treatments Thiametoxan + Chlorantraniliprole, Flupiradifuronae Triadimenol + Imidacloprido and their respective doses had a significant influence at 210 DAA, presenting greater development of height and length of branches in the coffee crop, when compared to the control where it is not. used any product. The mining bug infestation was verified, in the present work it is verified that the treatments Thiametoxan + Clorantraniliprole, Flupiradifuronae Triadimenol + Imidacloprid and their respective doses had a significant influence at 210 DAA, for the characteristics of mined leaves and mined leaves with live larvae, presenting greater control of the miner bug in the coffee culture, when compared to the control where it is not. used any product. Thus, the present work concludes that the treatments with Flupiradifurone and Thiametoxan + Chlorantraniliprole and Triadimenol + Imidacloprid were superior to Witness in terms of the physiological effect on the development of coffee culture. It is also concluded that, all treatments obtained an effective control of animal from Minas Gerais, except the Witness where nothing was applied.
