Control of Rust Diseases by Resistant Varieties

Puccinia spp.

Recognize the problem

Losses are often severe (50 to 70%) over a large area and individual fields can be totally destroyed by susceptible varieties to rust diseases.

Background

Wheat is a strategic crop in Afghanistan and important to country farmers. Serious damage to wheat has been recorded due to infection by rust diseases (leaf rust Puccinia recondita, Yellow rust Puccinia striiformis and stem rust Puccinia graminis). Use of resistance varieties can result in maximum yields whilst avoiding rust diseases.

Management

Yellow Rust: The appearance of yellow streak (pre-pustules), followed by small, bright, yellow elongated uredial pustules arranged in conspicuous rows on the leaves, leaf sheaths and glumes.

Leaf Rust: Circular or oval, orange pustules on the upper surface of infected leaves. Pustules are more scattered and larger in size compared to stripe rust.

Stem Rust: Uredinia are orange to dark red in colour and form on both surfaces of leaves. They are elliptical to elongate and are larger than those of leaf and stripe rusts. As wheat ripens, the uredinial stage turns into a new stage known as the telial stage
