Murali Agri Rich Suresh Gollar Pranshu Raghuwanshi i have give urea and vermicompost today, I can understand it is nitrogen issue also but at same times leaves are falling down and branches is turning brown and getting dead, many branches after falling leaves turned brown and got dead, i am afraid of reverse death of plant. see the attached pictures

Vivek Gurkha sir it's Stem Rot if you watering too much then it's occurred or àccess water around root zone also a reason

Vivek Gurkha sir now at this stage it's hard to cover if ýou need þo try please apply trichoderma fungicide in your vermicompost and mix it well
