Although this disease can be reproduced by inoculations of the lower trunk, the bud and entire stem is eventually rotted on some plants. Magnesium (Mg) Deficiency: Magnesium deficiency is never fatal and is primarily a cosmetic problem in landscape palms. 3. Since ornamental palms have a high aesthetic value, leaf spots that are of minor consequence in a plantation are a major problem for the ornamental nursery industry and in the landscape.

Some disease causing organisms are very specific, infecting a specific palm with a particular disease. The leaves of Raphia regalis can reach 82 feet long (18), and the famous double coconut seed of Lodoicea maldivica can weigh 50 pounds (13). For landscapes we are concerned primarily with diseases that harm the palm in such a way as to cause undesirable (not aesthetic) symptoms or predispose the palm to failure. 5. Moisture control is extremely important for diseases caused by Phytophthora spp. These nuts are borne on infected rachilla (inflorescence stalks), and stem ends attached to the diseased rachilla are infected.

Most palms generally require low levels of N, especially in comparison to turfgrass. In some cases, iron deficiency symptoms can be temporarily alleviated by regular foliar applications of chelated iron or iron sulfate, but long term corrections will only occur when the poor soil aeration or proper planting depth is corrected. Palms are beautiful plants that flower and produce gorgeous shades of yellow to green fronds. The flowers of the palm arise from under the crownshaft. Boron (B) Deficiency: Boron deficiency in palms can cause leaves to appear small and crumpled. For example, the primary reason for death of large royal palms (Roystonea regia) in southern Florida is potassium deficiency. Serial cross-sections of infected palm stem tissue show a disease progression pattern that is cone-shaped, with the greatest portion of diseased trunk at the soil line and the disease progressing upwards in the center of the trunk (Figs. Phytophthora drechsleri and P. nicotianae produce non-deciduous sporangia and infect the lower sections of stems (trunks). Internal rot of leaf base of Cocos nucifera caused by Phytophthora katsurae. Wet foliage will encourage zoospore formation, and these zoospores are believed to swim to stomatal openings (tiny pores on the surface of leaves and stems for gas exchange) and penetrate healthy leaves. ), Fig. They love well drained soils like those most similar to a beach environment. Growth of mycelium on infected trunk sections after incubation in moist chamber. Oospore of Phytophthora katsurae formed in host tissue and lacking protuberances. 2RTS + Ready to Spray (A hose-end spray bottle). As the iron deficiency becomes more severe, new leaves will show extensive tip necrosis, and there will be a reduction in leaf size. The top surface of G. zonatum has distinct zones of growth, hence the species name (Fig. The disease begins as small brownish flecks that expand to angular, irregularly shaped leaf spots and finally into large blighted areas.
