What is wrong with my Tipu tree (Tipuana tipu)?

Are there any reddish-brown streaks on the outer and inner bark off your Tipu tree, as well as gum or dark sap oozing from the infected area?

Are the leaves of your Tipu tree distorted, yellow, and stippled?

Are the roots of your Tipu tree dark brown and is the tree is wilting, yellowing, and dying?

Is there a white layer formed on the branches of your Tipu tree and nearby surfaces?

These symptoms in Tipu trees indicate a fungal disease known as Phytophthora Root or Crown Rot. Phytophthora pathogens thrive in wet conditions, and the risk of disease can be reduced with good water management. The disease tends to affect Tipu trees and other plants in poorly drained areas, where susceptible plants are surrounded by standing water or saturated soil for prolonged periods. Provide adequate drainage for your Tipu tree in order to minimize the risk of such diseases.

Tipu tree (Tipuana tipu) leaves stippled with yellow are caused by mites. These tiny, spider-like pests feed on the leaves of Tipu trees by sucking sap from the underside of the plants' leaves. You can control spider mites by spraying your Tipu tree thoroughly with water 2-3 times a day for several days. For severe infestations, spray the plant with insecticidal soap.

These symptoms in Tipu trees indicate a fungal disease known as Pythium Root Rot. Do not overwater your Tipu tree. Remove affected plants and their roots, and discard surrounding soil. Plant your Tipu tree only in the pasteurized soil. Hold back on fertilizing too. Keep hose ends off the ground. Apply a copper-based fungicide to protect your tipu tree.

Glassy-winged sharpshooters drain leaf fluids in Tipu trees. The fluid waste they excrete dries to form a white layer on the branches and nearby surfaces. These bugs transmit the deadly Xylella fastidiosa bacteria. Organic insecticidal soap controls these pests, but complete control on large trees requires patience.

Tipu psyllid (Platycorypha nigrivirga) is an invasive, exotic insect that attacks young foliage and branches of Tipu trees. Extensive feeding may cause distorted shoots, curled leaves, and premature leaf drop. Adults and nymphs produce copious amounts of honeydew, which fosters the growth of black sooty mold on leaves and branches. Provide the appropriate amount of irrigation and avoid applying excessive nitrogen fertilizer to suppress populations. Proper pruning can also help to lower psyllid numbers; make cuts just above branch crotches and nodes instead of shearing off terminals, which stimulates the new growth that psyllids prefer for feeding and egg-laying.
