The Emergence of Fusarium oxysporum f. sp. apii Race 4 Causing Fusarium Wilt on Celery in South Florida

Larissa Carvalho Ferreira, Anna Mészáros, and Katia Viana Xavier

Celery (Apium graveolens L.) production in south Florida spans approximately 1,500 acres yearly. Fusarium wilt, caused by Fusarium oxysporum f. sp. apii (Foa) race 4, emerged as a significant threat to celery production in the Everglades Agricultural Area (EAA) in Florida in 2022. Since it was first reported in the United States in Michigan in 1914, Foa has evolved into four different pathogenic races. In 2013, race 4 was first reported in California, ?and since then, it has been causing substantial losses to celery growers. The first occurrence in south Florida is critically alarming because (1) race 4 is the most virulent among the four races, (2) there is a lack of effective chemical and varietal control options for EAA Florida growers, and (3) this pathogen can survive in the soil for many years. This publication provides novel information to growers, Extension agents, and crop consultants of the celery industry in Florida regarding disease identification and management.

Escarole and Endive: Nutritious Leafy Vegetables with High Potential for Floridians

Germán Sandoya, Makou Lin, Jeongim Kim, and Steven Sargent

Escaroles and endives are two leafy vegetables of the Compositae family rich in nutrients and minerals. Both crops are uncommon in the United States, but both are planted in wintertime in Florida and in other states such as California and New Jersey. This publication aims the public and inform of their use in the leafy vegetable industry in Florida. As other leafy vegetables, escaroles and endives are susceptible to pests and diseases and other physiological disorders such as pink rib at postharvest. Using the correct management practices and the correct cultivars adapted for Florida could help producers in fields and in the home garden to achieve a successful crop.

Tar Spot of Maize in Florida

Larissa Carvalho Ferreira, Vitor Augusto Silva de Moura, Marcio F. R. Resende, and Katia Viana Xavier

Tar spot, a fungal foliar disease, affects most maize types commonly grown in Florida, such as sweet corn, field corn, and criollo corn. This disease is characterized by brown-to-black, raised structures called stromata, which are embedded in leaf tissue. As a polycyclic disease, tar spot lesions can increase in number as the disease progresses throughout the growing season, leading to reduction of photosynthetic area on the leaves. Tar spot has recently emerged as a significant threat in Florida and in the United States, with reports of up to 100% incidence in maize fields in south Florida. Tar spot occurrence and development in Florida is influenced by several factors, such as environmental conditions, maize types, crop maintenance, and corn growth stages. The purpose of this publication is to promote awareness among Florida growers regarding this newly identified disease and its management practices.

Current and Emerging Protocols for Carbon Measurement in Agricultural Soils

Suraj Melkani, Noel Manirakiza, Shirley M. Baker, and Jehangir H. Bhadha

Soils have the capacity to function as a sink of atmospheric carbon dioxide and are crucial for climate regulation. Soil have the potential to store around 1.5 to 2.4 trillion metric tons of C in the soil globally. They contain large C pools that can store three times more C than the atmosphere and four times more than plants. These massive C sinks have the potential to reverse soil degradation, mitigate climate change, and enhance food security. It is therefore essential to monitor the C cycle by accurately measuring the amount of soil C in agricultural fields. This can help in developing sustainable management practices that can minimize C emissions and sequester C into the soil from the atmosphere. This publication describes the various current and emerging protocols that can be used to measure soil C.

Tar Spot of Maize in Florida

Larissa Carvalho Ferreira, Vitor Augusto Silva de Moura, Marcio F. R. Resende, and Katia Viana Xavier

Tar spot, a fungal foliar disease, affects most maize types commonly grown in Florida, such as sweet corn, field corn, and criollo corn. This disease is characterized by brown-to-black, raised structures called stromata, which are embedded in leaf tissue. As a polycyclic disease, tar spot lesions can increase in number as the disease progresses throughout the growing season, leading to reduction of photosynthetic area on the leaves. Tar spot has recently emerged as a significant threat in Florida and in the United States, with reports of up to 100% incidence in maize fields in south Florida. Tar spot occurrence and development in Florida is influenced by several factors, such as environmental conditions, maize types, crop maintenance, and corn growth stages. The purpose of this publication is to promote awareness among Florida growers regarding this newly identified disease and its management practices.

The Emergence of Fusarium oxysporum f. sp. apii Race 4 Causing Fusarium Wilt on Celery in South Florida

Larissa Carvalho Ferreira, Anna Mészáros, and Katia Viana Xavier

Celery (Apium graveolens L.) production in south Florida spans approximately 1,500 acres yearly. Fusarium wilt, caused by Fusarium oxysporum f. sp. apii (Foa) race 4, emerged as a significant threat to celery production in the Everglades Agricultural Area (EAA) in Florida in 2022. Since it was first reported in the United States in Michigan in 1914, Foa has evolved into four different pathogenic races. In 2013, race 4 was first reported in California, ?and since then, it has been causing substantial losses to celery growers. The first occurrence in south Florida is critically alarming because (1) race 4 is the most virulent among the four races, (2) there is a lack of effective chemical and varietal control options for EAA Florida growers, and (3) this pathogen can survive in the soil for many years. This publication provides novel information to growers, Extension agents, and crop consultants of the celery industry in Florida regarding disease identification and management.

Trends in Florida Rice Production and Varieties

Jehangir H. Bhadha, Luigi Trotta, Daniel Cavazos, and Matthew VanWeelden

This publication sheds light on the trends of rice acreage and yields from 2008 to 2021. Nearly 23,000 acres of flooded rice were planted in south Florida in 2021. Growing flooded rice is a good Best Management Practice for growers in the region because it has been shown to reduce pest pressure and improve soil quality. The publication also highlights some of the recent varieties of rice that are grown in the region.

Weed Management in Rice

Weeds in Florida Sugarcane as Rice Stink Bug Hosts

Calvin Odero, Michael Karounos, and Ron Cherry

Rice is a rotational crop in the sugarcane production system on organic soils in the Everglades Agricultural Area in southern Florida. Several insects and weeds can affect production and profitability of rice. Management of fall panicum in rice and in sugarcane fields surrounding rice fields is important to mitigate risks posed by weeds and the rice stink bug complex in Florida rice.
