NIHORT provides Control Measures against New Virus Disease Attacking Okra Plants in Nigeria

The National Horticultural Research Institute (NIHORT) has confirmed the emergence of a new virus disease affecting Okra plants in various regions of Nigeria.

This alarming development has led to a rapid disease outbreak, causing more than 70 percent loss of Okra plants in certain areas and posing a significant threat to Okra production nationwide.

The institute’s multidisciplinary team, during ad hoc visits to Okra farms, observed unusual symptoms consisting of leaf curl associated with enations or outgrowths. These symptoms are distinct from the typical leaf curl and vein yellowing observed in virus-infected Okra plants.

Additionally, high populations of aphids and leafhoppers, known as vectors, have been observed on the leaves of affected Okra plants.

To address this outbreak, NIHORT urges farmers to be vigilant for the symptoms of the new virus disease and take immediate action. They advise farmers to look out for the presence of high populations of aphids and leafhoppers and the initial expression of small pin-head concentrations or outgrowths on the under surface of Okra leaves.

As the disease progresses, affected Okra plants show a twisting of the necrotic leaves, which become thick and leathery, resulting in severe stunting of the plants and deformed fruits that are unsuitable for marketing.

In response to the devastating impact on Okra farmers, NIHORT is on high alert to curtail the outbreak and minimize negative economic consequences. The institute emphasizes the need for stakeholders across the country to be aware of this potential threat and join efforts to mitigate its effects on Okra production.

As an interim control measure, NIHORT suggests spraying Okra farms with synthetic insecticide at a rate of 20ml/15lt of water weekly under severe infestations to contain the vectors responsible for transmitting the virus.

However, the institute is also intensifying research efforts to develop a sustainable Integrated Pest Management (IPM) package specifically designed to arrest the new virus epidemic attacking Okra production.

The outbreak of the new virus disease affecting Okra plants in Nigeria demands urgent attention and action from all stakeholders.

By implementing effective control measures, such as spraying with synthetic insecticides and supporting ongoing research into Integrated Pest Management (IPM), the nation can combat the disease, safeguard Okra production, and protect the livelihoods of farmers dependent on this vital crop.
