Avaliações de produtividade de variedades de cana-de-açúcar correlacionada quanto a incidência e severidade de doenças

Abstract

The evaluation of diseases in all cultures that generate a source of income in Brazil is a necessity to be carried out. Since the phytopathological evaluation, quantifying and qualifying these diseases, makes it possible to understand several factors related to crops, among these are the consequences generated in the yield of these crops, based on the evolution of these diseases in plants, in relation to sugarcane we have the indices productivity of tons of cane per hectare (TCH) and tons of sugar per hectare (TAH), considering the percentage of total reducible sugar (ATR). The main factor to assess a disease involves the presence of abiotic factors, such as climate variations and soil classification, and biotic factors, such as the interaction between different organisms in that particular environment. In this sense, the objective of this work was to evaluate related attributes between the sugarcane crop (Saccharum officinarum), in the state of Minas Gerais, more specifically in the Minas Gerais triangle, with possible diseases related to sugarcane. according to the favorable and unfavorable conditions for the development and appearance of diseases correlated through the Pearson's ratio coefficient to the productivity of tons of cane per hectare (TCH) and tons of sugar per hectare (TAH), taking into account the maturation of the percentage of total sugar recoverable (ATR), during the period from May 2019 to April 2020.
