The spores land on the soil and germinate. The hyphae then grow over the plant roots and up into the woody trunk. The fungus damages the palm trunk closest to the soil first, expands in diameter and moves up the center of the trunk causing a cone like shape of infected trunk.
A healthy tree naturally combats heart rot through a process called compartmentalization. The tree grows around the decayed wood tissue and prevents the fungus from spreading to a larger area of the trunk. Providing a tree with the necessary nutrients, water, and growing conditions will promote healthy growth and minimize rot.
Butt rot is a disease of plants, mostly trees, caused by fungi. The fungus attacks the moist, poorly protected undersurface of tree trunk's thickest part (the "butt" above the root, as opposed to "top"), where the end of the stem makes contact with the soil. It may affect the roots as well, causing a disease known as root rot. It then moves up ...
Unless the removal of these dead spear leaves occurs, this gives a chance for the vector to use these diseased spear leaves and transmit the disease to other nearby susceptible palm trees. [2] If the spear leaf has not yet been killed by TPPD, antibiotics are added to afflicted palm trees by injecting it into the trunk of the tree.
Slime flux, also known as bacterial slime or bacterial wetwood, is a bacterial disease of certain trees, primarily elm, cottonwood, poplar, boxelder, ash, aspen, fruitless mulberry and oak. A wound to the bark, caused by pruning, insects, poor branch angles or natural cracks and splits, causes sap to ooze from the wound. Bacteria may infect ...
The fungus has been isolated from a wide variety of palm tissue. The fungus is not host specific so the disease could be present in many more types of palm , but further research needs to be done. The fungus has also been known to infect pygmy date palm ( Phoenix roebelenii ) and has been a big problem in Florida during the winter months. [ 1 ]
Cadang-cadang is a disease caused by Coconut cadang-cadang viroid (CCCVd, Cocadviroid cadangi), a lethal viroid of several palms including coconut (Cocos nucifera), African oil palm (Elaeis guineensis), anahaw (Saribus rotundifolius), and buri (Corypha utan). The name cadang-cadang comes from the word gadang-gadang that means dying in Bicol. [1]
To manage this disease scouting is the most important aspect; early detection of infected trees may save plantations. If an infected tree is found it must be removed, treated with herbicide and cut down. Leaving the stump behind can lead to vector reproduction and spread the nematode.
