damages caused by rice blight disease and prevention methods
What is rice blight disease? The rice bacteria blight disease is a type of disease that attacks rice as a crop. it is a fungus type of attack
the attack or disease known as rice Bacteria blight is caused by a fungus called piricularia oryzae
“The genus Xanthomonas, which mostly comprises phytopathogenic bacteria, is a member of the family Xanthomonadaceae. Among xanthomonads, Xanthomonas oryzae pv. oryzae causes bacterial blight (BB) of rice which is one of the most important diseases of rice in most of the rice growing countries”
The transmission method or transmitting method of rice blight disease
rice blight disease is an airborne type of disease deposited on leaves.
What this means when we say airborne disease is a type of disease transmitted through the air.
In areas of wet season where rice is planted in the swampy regions of the world
the spread of bacterial Blight of rice can also take place when water washes down the disease from the leaf of an infected plant to the root whereby the nearest plant can also absorb it and infection spreads on
So the bacterial blight disease is also a waterborne
So what are the symptoms of the rice bacteria blight disease rice crop
We can recognise the presence of the bacteria rice blight disease through the following means
the first method of recognition is that there will be a small longitudinal red spots which eventually will turn grey or brown
So if you are a rice farmer and you are keen on making profit from your crops, better be on the lookout for red spots that are small but longitudinal on leaves of rice on their stands
One of the major effect or damages caused by the rice blight is that it reduces crop yield
This disease will eventually reduce the capacity of the rice to carry out photosynthesis therefore weakening the crop
Rice Bacterial blight disease first shows up as water-soaked streaks which spread from the leaf tips and collums, becoming bigger and eventually releasing a milky liquid that dries into yellow droplets.
Characteristic of bacteria blight of rice, is the grayish white which spread on the leaves, signaling the late stages of infection, when leaves dry out and die.
Ways farmers can use to prevent and control the spread of rice blight disease
Various ways of controlling rice bacterial blight are limited in effectiveness that is to say they are not very effective in curbing the spread of the bacteria disease.
The use of Chemical control methods has been grossly ineffective in reducing the effects of bacterial blight due to safety issues, and bacterial resistance capacity.
Biological control methods, rely on the use of bacterial killer of pathogens -disease-causing organisms, which can reduce bacterial blight of rice.,
most-common method of defending against rice bacterial blight is the cultivation of rice varieties. Which is the use of bacteria blight resistant varieties of rice
The use of clean seeds during planting of rice is very key
