Manejo fitossanitário do tomateiro com o uso de adubação foliar com silício

Abstract

The objective of this study was to evaluate the benefits that silicon gives the tomato to attack by insect pests and pathogens in the northern region of the state of Rio Grande do Sul. We evaluated the visual state every 30 days, fruit set, leaf damage caused by insect pests and fungi, chlorophyll content and productivity. The driving of the plants was performed in Viçosa system 2015 that consists of the use of narrow ribbon and forming a structure "V" at an angle relative to the ground 70°. The design was a randomized block design. Comparisons between means were made by applying the Tukey test at 5% probability. It is concluded that the use of foliar fertilization with silicon has protective effect, significantly increasing the productivity of the tomato crop, justifying its use.
