Organic blood oranges from Agrofair in Italy

There is room for growth on the organic citrus market

The organic citrus market is in full swing. Besides the superpower in this market, Spain, importers are now finding their way only too well to countries such as Greece, Italy, and South Africa.

“We specifically chose Italy for the import of our organic citrus,” says Martin Pietersma from Agrofair. This company, based in Barendrecht, the Netherlands, imports, among other products, organic blood oranges from Sicily. “There are, naturally, other countries besides Italy where this product is available, such as Greece and, of course, Spain.”

Cover Crops

Can cover crops save Florida’s citrus?

Citrus greening has devastated the Sunshine State’s orange industry. Researchers and pioneering farmers see cover crops as a road to recovery.

For the last couple of decades, a tiny insect called the Asian citrus psyllid has fed on the stems and leaves of the orange trees in Florida, infecting them with bacteria that cause a lethal disease called citrus greening. The bacterial disease, huanglongbing (HLB), originated in China and has destroyed 90 percent of the state’s groves, devastating its $9 billion citrus industry.

HLB now in Kenya: Preparations to mitigate its impact on the Southern African citrus industry.

The presence of Diaphorina citri (Asian citrus psyllid, or ACP), the primary vector of the dreaded Huanglongbing disease (HLB, or Asian Citrus Greening), was first reported in east Africa in Tanzania (2015) and Kenya (2016). Surveys that CRI conducted in collaboration with local scientists, confirmed the presence of ACP in the eastern regions of Tanzania. Recently HLB, previously known to occur in some parts of Ethiopia, was detected on the east coast of Kenya (Fig. 1). The recent detection of HLB in Kenya brings it considerably closer to citrus production in Southern Africa. CRI has engaged in a process with Department of Agriculture, Land Reform and Rural Development (DALRRD) to encourage Kenyan partners to scope the possibility of containing and eradicating the disease in the region.

Citrus Export Covid-19

Strong demand for SA citrus at start of 2020 export season

A strong increase in global demand for citrus has so far been evident in the 2020 export season, according to Justin Chadwick, CEO of the Citrus Growers’ Association of Southern Africa.

In a statement, Chadwick said increased global demand for lemons had resulted in 4,5 million 15kg-equivalent cartons being shipped to date. This was double the 1,8 million cartons exported during the same period in 2019.

Spain: Koppert studies efficacy of beneficial fungus for the biological control of HLB

Beneficial microorganisms are becoming increasingly important in the biological control of citrus pests, as a complement to the release of auxiliary insects. Proof of this is the research carried out by Koppert Spain, which aims to confirm the efficacy of an entomopathogenic fungus that could help control Trioza erytreae, one of the insects that transmits huanglongbing (HLB), or citrus greening. “Koppert’s objective is to develop a biological solution that may be available to producers if the insect that transmits the HLB arrived in Spain,” said Javier Calvo, researching entomologist at Koppert, in the framework of a Citrus Technical Conference held in El Rompido (province of Huelva) and Palma del Río (province of Cordoba).

Trained dogs - Citrus Greening

Trained dogs are the most efficient way to hunt citrus industry’s biggest threat

Dogs specially trained by Agriculture Research Service (ARS) scientists have proven to be the most efficient way to detect huanglongbing—also known as citrus greening—according to a paper just published in the Proceedings of the National Academy of Sciences.

Currently, the only solid hope of curtailing the spread of citrus greening is to eliminate trees with the disease as quickly as possible to prevent further spread. Early detection of the citrus greening pathogen is crucial because trees can be infected and act as a source to spread the disease months or years before showing symptoms that are detectable by the naked eye.

The Pursuit Grows to Build Organic Matter in Citrus

Florida citrus growers have always understood the importance of soil health and the positive influence of microbial activity and diversity in production. As citrus greening (also known as HLB) has spread, reducing production by more than 70%, interest in how these tiny organisms can improve root health is increasing. Research showing the disease, which is spread by the Asian citrus psyllid, can reduce citrus fibrous-root density by 30% to 50% before symptoms become visible above ground only intensifies the interest to learn more.

Endulini Fruit introduces biological pest control in citrus

Consumers, and consequently supermarkets, demand products free of pesticide residues and with much of the citrus produced by Endulini Fruit being exported to Europe, the European Union Directive 2009/128/EC, which aims to reduce the risks and impact of pesticides on human health and the environment, has led to the popular citrus producer using softer pesticides and introducing biological pest control.
