Bacterial blight is a serious disease that affects pomegranate cultivation in India, which is caused by the bacterium Xanthomonas axonopodis pv. punicae. The disease can cause significant damage to pomegranate trees, leading to reduced yield (in some cases up to 90%) and poor fruit quality. This, in turn, can affect the marketing value of the fruits and lead to significant economic losses for farmers. Thus, effective disease management strategies are crucial for controlling bacterial blight in pomegranate and maintaining productivity.
Bacterial blight disease is more severe during fruiting stage. The bacterium can survive on infected plant debris, in soil, and in plant tissue, and can be transmitted through various means as given below.
(Note: Always prepare Bordeaux mixture fresh and use on the same day)
In order to effectively manage bacterial blight in pomegranate, it is recommended to implement an integrated approach that combines preventive measures with other methods, as relying solely on chemical control is ineffective.
The below mentioned chemicals can be used alone or in combinations.
