Drones used for first time in SL to fight rubber leaf fungus
For the first time in Sri Lanka, drone technology is being used to control the leaf fungus disease in rubber plantations, Company Estate Reforms, Tea Estate Related Crops, Tea Factory Modernization and Tea Export Promotion State Minister Kanaka Herath says.
Under the project, Minister Herath said it had been planned to spray fungal controlling chemicals using drones, which is designed especially for agricultural purposes.
The State Minister while observing a chemical spraying pilot project using drones recently said that the fungal disease that infects rubber plantations should be brought under control promptly otherwise it would be a huge threat to the entire rubber industry. He assumed that with using drone technology as well as modern pest control methods they would be able to control the fungal disease quickly and prevent it from spreading to other areas.
The pilot project of spraying chemicals with drones was carried out at the Panawatta Estate in Yatiyantota recently under the supervision of Rubber Research Institute (RRI) officials.
To control the fungal disease named Pestalotiopsis, chemicals are sprayed on the leaves of the rubber trees. Affected rubber leaves can be seen with yellow spots and gradually the green part of the leaf will fade away.
“Applying chemicals onto the leaves using drones is rather effective than applying chemicals from the ground as there are several practical issues. It is practically difficult to carry heavy chemical spaying machines throughout the plantation as most of the rubber plantations are on hilly areas” State Minister Herath said.
The fungal disease, which was harmful to rubber cultivation, was first reported in the Kalawana area in Ratnapura in 2019 and today it had spread to other districts such as Kegalle and Kalutara. Rubber Research Institute Deputy Director Dr. Priyani Seneviratne said.
There was a high probability of the disease spreading especially in areas with a high rainfall, she said.
“The disease was reported in 2017 in Indonesia and 2018 in Malaysia. On average, it is estimated that there will be a 30 per cent reduction in yields. “she pointed out.
Not only rubber plantations but also many plants including avocado and a few others were affected by the fungal disease. If more than 50 per cent of leaves fall off, rubber taping for rubber latex cannot be carried out. In such occasions it is reported a yield drop around 30 per cent.
The RRI Deputy Director said that the RRI would study the productivity of the pilot project and make extensive use of drone technology to prevent the disease.
Dr Seneviratne also noted that although many of the fungal diseases were usually prevalent in one rubber species and are resistant to other strains, it was observed that the particular fungal disease had spread to all species.

Malaysia declares emergency in Sarawak as haze from Indonesia worsens
Malaysia has declared a state of emergency in a district in Sarawak state after haze caused by wildfires in neighbouring Indonesia increased air pollution to “hazardous” levels.
King Sultan Ibrahim “has consented to the declaration of emergency throughout Serian Division, Sarawak, following haze conditions that have reached air pollution levels hazardous to public health and safety”, Prime Minister Anwar Ibrahim’s office said in a statement on Thursday.
The declaration followed a formal request from the Sarawak Disaster Management Committee after the region’s Air Pollutant Index reached levels warranting consideration of a local emergency.
Under the order, 647 schools in Serian will close from Monday until at least the end of next week, alongside government and private offices, plantations, construction sites and quarries, with only essential services continuing to operate.
The state’s disaster management authorities said a three-day cloud-seeding operation launched on Thursday would be extended to at least Monday, citing forecasts of “more conducive cloud formations” during that period.
Sarawak State Disaster Management Committee chairman Douglas Uggah Embas, speaking at a news conference in Kuching, stressed that the emergency applied only to Serian, not the entire state, but urged residents there to take the situation seriously.
“Please minimise outdoor activities and avoid strenuous activities outdoors,” he said.
Sarawak, in the northern part of Borneo island, has been heavily affected by haze for weeks, as have the neighbouring states of Sabah and Peninsular Malaysia.

Namal remanded until Sept. 18 over Airbus deal investigation
Sri Lanka Podujana Peramuna (SLPP) National Organiser and Parliamentarian Namal Rajapaksa was yesterday remanded until September 18 by the Colombo Chief Magistrate’s Court following his arrest by the Commission to Investigate Allegations of Bribery or Corruption (CIABOC) in connection with an investigation into the controversial SriLankan Airlines Airbus aircraft transaction.
Rajapaksa appeared before the CIABOC at around 9.15 am yesterday to record a statement after being summoned over the transaction. He was taken into custody following several hours of questioning and subsequently produced before the Colombo Chief Magistrate.
The investigation centres on allegations surrounding the acquisition of six Airbus A330 and eight A350 aircraft by SriLankan Airlines in 2013, in connection with an alleged USD 2 million bribe.
Former SriLankan Airlines Chief Executive Officer Kapila Chandrasena and his wife, Priyanka Niyomali Wijenayake, had previously been named in connection with the alleged bribery.
Chandrasena was arrested on March 12 as part of an investigation launched by the CIABOC under the Anti-Corruption Act and was subsequently released on bail. He was later found dead on May 8 while on bail, with police suspecting that his death was a suicide.
Open warrants have been issued for the arrest of Wijenayake, who is named as the second suspect, and Shamindra Rajapaksa, named as the third suspect, in the case pending before the Fort Magistrate’s Court in connection with the Airbus transaction.
The investigation has also received assistance from Airbus, with a delegation from the company’s parent group in France visiting Sri Lanka during the first week of August. The delegation provided statements and other assistance to the CIABOC as part of the ongoing inquiry.
Rajapaksa’s arrest and remand yesterday mark a further development in the widening investigation into the controversial aircraft deal.
