What is leaf streak disease?

Bacterial leaf streak is an important disease of wheat that can reduce yield up to 40% although losses are generally 10% or less. The disease is caused by Xanthomonas translucens pv. undulosa and is widespread in areas where small grains are grown, especially in warm and humid climates or under sprinkler irrigation.

What does leaf streak look like?

Symptoms appear as small, reddish-brown flecks and brown spots that develop on infected tissue. You may then see a central yellow streak along the midvein that begins at the leaf tip.

Chlorothalonil is a protectant fungicide and is more effective for managing daylily rust than propiconazole when applied as a foliar spray every 14 days (Dong et al. 2013). In addition, inhibition of urediniospore germination by chlorothalonil was similar to that of azoxystrobin and trifloxystrobin (Mueller et al.

Are yellow leaves a sign of overwatering?

Overwatering

Watering issues are generally the most common cause of yellowing leaves. When your plants are overwatered, the performance and vigor decrease. Oxygen is being pushed out of the soil, and the roots are simply “under aired” and suffocating. With little air, the roots will begin to drown and rot.

Allow fallow fields to dry in order to suppress disease agents in the soil and plant residues.

What is daylily rust?

Daylily rust is caused by the fungus Puccinia hemerocallidis and affects the leaves and scapes. ... In very mild winter climates the familiar yellow-orange powdery "summer spores" (urediospores) produced from the spots (pustules) on daylily leaves may cause repeated infection cycles year round.
