‘Lava Glow’—A New Red Fancy-Leaved Caladium Cultivar

Zhanao Deng, Natalia A. Peres, and Johan Desaeger

‘Lava Glow’ is a new and novel caladium cultivar that produces bright red to red-purple heart-shaped leaves with strong sunburn tolerance and is resistant to leaf spot diseases. This new 7-page publication of the UF/IFAS Environmental Horticulture Department is prepared for growers who are interested in growing caladium as a horticultural crop and for greenhouse or nursery growers who are interested in producing potted caladium plants. Written by Zhanao Deng, Natalia A. Peres, and Johan Desaeger.

Common Arthropod Pests in Blackberries and Pomegranates in Florida

Chastity Perry, Hugh A. Smith, Zhanao Deng, and Sriyanka Lahiri

Blackberry and pomegranate are growing in importance as alternative crops in Florida. In the past decade, blackberry production in Florida increased from 64 acres in 2007 to 173 acres in 2017.  The many health benefits acquired from these fruits make them good alternative options for growers in Florida to diversify their operations by planting some new and less traditional crops, providing them a niche in the Florida agriculture market. The intended audience of this publication includes blackberry and pomegranate growers in Florida as well as Extension agents providing expert recommendations to both these industries. The purpose of this publication is to share information derived from a one-year field survey on commonly encountered pests.

New Caladium Cultivars ‘Dots Delight’ and ‘Wonderland’

Zhanao Deng and Natalia A. Peres

Caladiums are ornamental aroids valued for their vibrant and morphologically diverse foliage. Grower surveys indicated that they planted more acres of lance-leaved cultivars in recent decades to accommodate rising consumer demand. The caladium breeding program at the UF/IFAS Gulf Coast Research and Education Center has been developing new lance-leaved cultivars that can produce attractive, robust plants with many bright, colorful leaves and improved tuber yield potential. The program has recently released two new lance-leaved cultivars. ‘Dots Delight’ is well suited for use in sunny landscapes, having excellent tolerance to sunburn and strong resistance to the leaf spot disease. Though they may need one to two additional weeks to produce potted plants, tuber yield potential is intermediate to high. ‘Wonderland’ is well suited for potted plant production in sunny or shady landscapes or gardens and has showed good leaf color display, sunburn tolerance, and leaf health.

A Step-by-Step Fertigation Guide for Blackberry Growers in Florida

Nurjahan Sriti, Elena Máximo-Salgado, Zhanao Deng, Jeffrey Williamson, and Guodong Liu

Blackberry cultivation offers significant opportunities for fruit producers in subtropical regions. Effective fertilizer management is essential for maximizing production. However, determining the optimal fertilizer application can be challenging as a result of variations in soil types and climate. To achieve the best results, it is important to follow the 5Rs of nutrient stewardship. (There are usually 4 Rs outside the unique environmental conditions of Florida.) These principles focus on applying the right fertilizer source at the right rate, at the right time, in the right place, and with the right irrigation. This guide provides Florida blackberry growers with practical recommendations for efficient fertigation practices to boost blackberry yields and improve nutrient use efficiency. It is intended for commercial growers, agricultural consultants, farm managers, Extension agents, Extension specialists, and others interested in blackberry production and sustainable farming.

Evaluating Pomegranate Cultivars for Resistance to Anthracnose Fruit Rot, a Severe Fungal Disease in Florida and Southeast United States

Alexander Schaller, Zhanao Deng, Gary E. Vallad, and John M. Chater

Pomegranate (Punica granatum L.) has primarily been cultivated at home in Florida and other southeastern states. Over the past 15 years, growers, nurseries, researchers, and Extension agents have explored the potential of pomegranate as an alternative fruit crop. Early field trials revealed that pomegranates are highly susceptible to Colletotrichum gloeosporioides, causing severe anthracnose fruit rot and premature fruit drop. The development and use of disease-resistant cultivars are considered some of the best methods to manage this disease. This publication presents our findings from evaluating 35 pomegranate cultivars under natural disease pressure in central Florida and by artificial inoculation. The susceptibility of such pomegranate cultivars varied widely, with six exhibiting resistance to anthracnose fruit rot. More comprehensive research is warranted to further develop anthracnose-resistant cultivars and to enhance our understanding of disease resistance in this crop.
