Answer 2

Answer:

In paddy water soaked, translucent streaks are observed on leaves due to Xanthomonas oryzae pv. oryzicola diseases

Explanation:

Bacterial leaf streak is caused by Xanthomonas oryzae pv. oryzicola.

In locations with high temperatures and high humidity, bacterial leaf streak develops.

It spreads to the upcoming planting season by seeds and infected stubbles. It can happen in fields where the bacteria X. oryzae pv. oryzicola are found on the leaves, in the water, or in the waste materials left over during harvest.

Particularly prevalent in Australia, South America, Madagascar, Asia, and Africa's tropical and subtropical regions are the disease.

• From maximal tillering to panicle initiation, it might have an impact on the plant during its early phases. Rice plants that are mature can quickly recover from leaf streak and suffer only minor reductions in grain yield.
• Small, water-soaked, linear lesions between leaf veins are the first signs of the condition. Initially dark green, these streaks later turn light brown to yellowish grey.
• When held up to the light, the lesions are translucent.
• In really severe cases, entire leaves may turn dark and die.
• On the surface of leaves, yellow droplets of bacterial ooze that are packed with bacterial cells can be seen in humid conditions.
