What This Bill Does

This document provides an overview of two primary sugarcane diseases in Florida: Sugarcane Rust and Sugarcane Mosaic Virus. It outlines identification symptoms, historical impact, and recommended management strategies for local growers.

Why it matters

Local sugarcane growers face potential yield losses of 20% to 40% from rust and must manage the spread of mosaic virus to protect crop viability.

Who It Affects

Groups the bill's text affects, as described in the record. Being affected is not a position for or against it.

Directly affected

Sugarcane growers

Growers must manage disease risks to prevent potential yield losses and select appropriate crop varieties.

Key Facts

  • Sugarcane rust is caused by the fungus Puccinia melanocephela and has been a threat in Florida since 1978.
  • Estimated yield losses from sugarcane rust range from 20% to 40% during severe infestations.
  • Rust lesions typically measure 2-10 mm in length, occasionally reaching 30 mm.
  • Sulfur is the only registered chemical for rust control, but studies show it is ineffective or not economically viable.
Show all 10 facts
  • Growers are advised to avoid planting susceptible varieties in low pH soil or areas with high phosphorus and potassium levels.
  • Fields recently treated with mill mud are highly prone to rust infection.
  • Sugarcane Mosaic Virus (SCMV) was first observed in Florida in 1996 on the CP 72-2086 cultivar.
  • Mosaic virus is primarily spread by aphid vectors and infected seed cane.
  • The most effective control for both diseases is the use of resistant plant varieties.
  • Varietal diversification is recommended to reduce selection pressure for specific rust variants.

Frequently Asked Questions

What is the best way to control sugarcane rust?
The most effective method is growing resistant varieties and diversifying the types of sugarcane planted to prevent the buildup of specific disease variants.
Can I use chemicals to treat sugarcane rust?
While sulfur is registered for use, research indicates it is either ineffective or does not provide a sufficient economic return to justify its use.
How is the Sugarcane Mosaic Virus spread?
It is primarily spread through and the use of infected seed cane.

Disease Emergence

The document highlights a clear shift in 1996 when the Mosaic Virus, previously not a problem in Florida, was identified in commercial crops.
