Detailed explanation-1: -The blight injures plants by forming blockages in xylem and phloem, inhibiting resource distribution and resulting in plant die-back and smaller fruit yields. As of 2020 there is no cure for the blight, and neither the causal agent nor spreading mechanism is known.
Detailed explanation-2: -Citrus Phytophthora Root Rot (also known as Brown Rot or Collar Rot) is a citrus tree disease caused by the soil-inhabiting fungus, Phytophthora. Root Rot symptoms include dark brown or black patches of hardened bark on the tree trunk, mainly at the base. It is also common for ooze to seep from the affected area.
Detailed explanation-3: -Excessive intercropping, faulty, excess or no manuring, improper use of irrigation water, are some of the common causes leading to citrus decline.
