Drones being used to fight blight disease in rubber plantations
Plantations State Minister Kanaka Herath stated that rubber growers should pay proper attention to the spread of a fungal disease associated with rubber cultivation which reduced the production of rubber latex by about 30 per cent.
Deputy Director of the Rubber Research Institute Dr. Priyani Seneviratne said that rubber growers should be vigilant to prevent the spread of leaf blight fungal diseases due to the prevailing rainy weather.
This fungal disease was found in rubber plantations in the island in both 2019 and 2020. This year too, the disease is associated with rubber growing districts such as Kegalle, Kalutara and Ratnapura has been identified.
This fungal disease, also known as Pestalotiopsis, is also known as leaf blight due to the shedding of leaves in rubber plantations. Although the average annual leaf fall in rubber plantations occurs from February to April, the leaves fall even after the normal leaf fall period in rubber plantations where the fungal disease has spread, she said.
According to Dr Seneviratne if any rubber plantation sheds leaves in or after May, it may be due to this new leaf fall disease. However, due to the current outbreak of Covid-19 pandemic and severe travel restrictions in the country to arrest its spread, it is practically difficult to inspect these crops or to control the disease in any way.
“It has been noticed that the disease is spreading rapidly due to the prevailing monsoon rainy weather. It is essential to know the extent of the affected areas to treat the disease and to prevent further spread of the disease.
Therefore, Dr. Seneviratne urged all rubber collectors to be vigilant about leaf fall during or after May. If a leaf fall has occurred on your rubber plantation during the month of May, please notify the Rubber Development Officer of the area where the rubber land is situated or call the following telephone number,” she Stated.
Accordingly, the Rubber Research Institute kindly requests the Rubber Growers to send details such as a picture of a fallen leaf, the address of the land, your telephone number, the clone belonging to the plantation and the extent of the land to this WhatsApp number 0772419482 .
The Minister pointed out that for the first time in Sri Lanka, a pilot project for spraying chemicals using drone technology was launched to control this disease. The pilot project carried out at Panawatta Estate, Yatiyantota, the chemical was sprayed on the leaves of the rubber leaves under the guidance of Rubber Research Institute officials.
Fungicide spraying has long been practiced from the root of the tree. Applying the chemical in this way is practically impossible. As a solution to this situation, drones are used to apply chemicals directly on rubber leaves. The pilot project has proven that the application of the substance is more efficient and effective. Therefore, this fungal disease was successfully controlled using drones.
State Minister Herath said that in addition to drone technology, modern pest control methods will be used to control the spread of this fungal disease in rubber plantations and prevent its further spread.
The fungal disease, which affects rubber plantations, was first reported in the Kalawana area in Ratnapura in 2019 and has now spread to districts such as Kegalle and Kalutara. Dr. Seneviratne said that there is a high probability of the spread of this fungal disease in areas with high rainfall.
The disease was reported from Indonesia in 2017 and Malaysia in 2018. It is estimated that production could be reduced by as much as 30 per cent. This fungal disease causes damage not only for rubber cultivation but also for many plants including avocado.
If the leaf shedding is more than 50 per cent, the rubber taping should not be carried out. This could reduce rubber production by as much as 30 per cent.
It can be observed that if one fungus infects one rubber variant, it is often resistant to the other variants. However, it is observed that the disease spreads to all species, she declared.

West Asian conflict benefits China-managed H’tota Port
The ongoing West Asia war, triggered by joint Israel-US attack on Iran on 28 Februar, has benefited the China-run Hambantota International Port (HIP).With Iran imposing restrictions on the Strait of Hormuz shipping, in retaliation for unprovoked attack, thereby choking vital shipping routes, particularly for crude oil and refined oil products, HIP situated, along the East-West shipping corridor, has received the anticipated attention.
Soon after the sinking of an unarmed Iranian frigate, just outside Sri Lanka’s territorial waters, in India’s backyard, Indian External Affairs Minister Subrahmanyam Jaishankar categorised HIP as a foreign military base, along with Diego Garcia, Bahrain and Djibouti, where both the US and China maintained major bases.
HIP, in a press release issued on Sunday (05), declared that the Port has significantly expanded its operational capacity, in response to a sharp surge in global shipping volumes, resulting from the West Asia conflict.
The company asserted that the developing situation reinforced its position as a key alternative hub along the East–West shipping corridor.
The port has doubled its Roll-on/Roll-off (RoRo) yard capacity and increased its container yard capacity by 30%, as shipping lines divert operations away from disrupted routes in search of stable and efficient alternatives.
HIP is situated just 10 nautical miles from the main East–West shipping route, allowing vessels to divert with minimal deviation while maintaining schedule integrity.
The Chinese government-owned China Merchant Port Holdings (CMPort) under controversial circumstances acquired controlling interests of the Hambantota port in 2017 during the Yahapalanaya administration. Although the Sri Lankan government repeatedly said that Sri Lanka was paid USD 1.12 bn according to the HIP website CMPort invested $974 mn in the HIP and held 85 percent of the shares.
The 2017 agreement granted CMPort a 99-year lease to develop, manage and operate the Port area. The Supreme Court dismissed a fundamental rights petition filed by lawmaker Vasudeva Nanayakkara pointing out that the original agreements pertaining to the Hambantota port had been signed in 2012 and 2013 during Mahinda Rajapaksa’s tenure as the president when he was a member of the Rajapaksa Cabinet.
The HIP press release quoted CEO of HIP Wilson Qu as having said: “What we are witnessing today is a structural shift in global shipping patterns. At HIP, we have focused on building the capacity and operational agility to respond to such changes. Our ability to scale quickly, combined with our location, allows us to support global shipping lines when reliability becomes critical. Looking ahead, we will continue to invest in infrastructure and capabilities to strengthen Hambantota’s role as a key logistics and transshipment hub in the region.”
The rise in both vehicle transshipment and container volumes has driven yard utilization levels to the highest in HIP’s history, highlighting the scale of ongoing supply chain disruptions and the port’s growing strategic importance in global trade.
To accommodate increased throughput, HIP has rapidly expanded yard space across both cargo segments, enabling it to handle higher volumes while maintaining operational efficiency and minimizing congestion. Expanding capacity within a short time frame in a live port environment presents considerable operational and technical challenges and requires significant investment. However, through close coordination across management, engineering and operational teams, HIP was able to deliver these enhancements in step with rising demand.
The HIP statement added: “The expansion reflects Hambantota International Port’s continued development as a resilient logistics platform in the Indian Ocean, as geopolitical developments reshape established maritime routes and increase demand for alternative hubs. As infrastructure scales in tandem with demand, HIP is increasingly positioned to capture a larger share of regional transshipment volumes while supporting the continuity of global supply chains.”
Amidst the continuing uncertainty caused by war and growing threat to international shipping the Hambantota International Port Group (HIPG) the owning group of HIP recently finalised an agreement to invest USD 108 mn to procure new container handling equipment- six quay cranes, 16 rubber-tyred gantry cranes (RTGs) and 40 trailers, under the initial phase of the port’s Phase II container terminal development.
