Which is best fungicide for sugarcane?
Sugarcane smut, caused by Sporisorium scitamineum, is one of the most devastating diseases of sugarcane worldwide. Triazole fungicides such as propiconazole and triadimefon have been routinely used as dip treatments to protect seed-cane (stalk cuttings) from infection by sugarcane smut fungus.
Which pathogen caused diseased to red rot of sugarcane?
Sugarcane (Saccharum spp.) is a commercially important crop, vulnerable to fungal disease red rot caused by Colletotrichum falcatum Went. The pathogen attacks sucrose accumulating parenchyma cells of cane stalk leading to severe losses in cane yield and sugar recovery.

How do you control colletotrichum Gloeosporioides?
Chemical control of the disease requires biweekly or monthly application of fungicides, which could be damaging to the environment, and frequent use of chemical fungicides could lead to the development of fungicide-resistant strains (Onyeka et al. 2006).
How to control red rot of sugarcane?
Red rot of sugarcane is hard to control because the stalk from which seeds are prepared has been largely affected from the time of planting, and fungicides cannot reach the infected tissues inside a diseased seed sett. Therefore careful selection of red rot-free seed setts is recommended for planting.
What is red rot of sugarcane caused by Deuteromycetes?
In this article we will discuss about the red rot of sugarcane caused by deuteromycetes. Host: Saccharum officinarum L. It is a serious and destructive disease of sugarcane. It occurs in tropical and subtropical regions of the world where sugarcane is cultivated extensively.
