Malaysian Oil Palm Industry
• The oil palm is an important commodity in Southeast Asia (SEA).
• The oil palm industry is the fourth-largest contributor to Malaysia's national revenue, accounting for more than 5% of annual exports.
• The total area of oil palm in Malaysia is 5.8 million hectares, with a total export revenue of palm oil and palm-based products valued of more than RM 77 billion in 2017

South East Asia is still free from these diseases:
i. Bud rot ii. Vascular wilt iii. Red ring iv. Sudden wilt v. Lethal wilt These diseases are very devastating and posed
the highest risk to the Malaysian oil palm industry

Ganoderma
Lethal wilt
Vascular wilt
Severity of Bud Rot disease in Latin America
• Seriously affecting Latin America for more than 40 years, in Colombia, Brazil,
Ecuador, Panama and Surinam (Turner and Gillbanks, 2003).
• Causing serious impact with >30,000 ha out of 35,000 ha (85%) oil palm areas
destroyed between 2006 and 2009 (Martinez et al., PIPOC 2011).

(Martinez et al., PIPOC 2011)
Causal Pathogen: Phytophthora palmivora
mating type A2 (fungus-like) (Toress et al., 2010; Plant Disease – Cenipalma, Colombia; Uni. of Florida & Uni. of California, USA)
Fungi and bacteria to be associated
with the disease (pathogenicity has not been conclusively proven):
- F. solani
- T. paradoxa
- Pythium spp.
Oil Palm Biosecurity Plan
Movement of planting materials and germplasm in
response to growing demand
Many pests and diseases of oil palm are not yet
recorded in SE Asia.
• represent threats to the oil palm industry here and in the
region
• Prevent new pests, diseases and weeds from
entering the country and becoming established
• Manage incursions to eradicate the pests where
feasible or lessen their impact
• Ensure preparedness and response that is
internationally recognized
Biosecurity plan for Oil Palm in Malaysia
• Biosecurity is a process –aimed at stopping unwanted pests and diseases from arriving in e.g. Malaysia, detecting and rapidly eradicating them if they do arrive, or (if they become established) trying to minimize their impact by using long-term management strategies.
• Through out the years - Malaysia’s national quarantine system has helped to prevent the introduction of harmful exotic pests and diseases into the country.
• In Malaysia, Sanitary and phytosanitary (SPS) measures are quarantine and biosecurity measures which applied to protect human, animal or plant life or health from risks arising from the introduction, establishment and spread of pests and diseases – by Department of Agriculture Malaysia (DOA).

Oil palm industry in Malaysia
- Biosecurity issues and challenges
● Over 40 oil palm growing countries with over 600 pests and diseases
recorded
● Movement of planting materials and germplasm in response to growing
demand
● Many pests and diseases of oil palm are not yet recorded in SE Asia.
● They represent threats to the oil palm industry here and in the region
Biosecurity Plan is required to:
Prevent new pests, diseases and weeds from entering the country and
becoming established
Manage incursions to eradicate the pests where feasible or lessen their
impact
Ensure an appropriate preparedness and response capacity that is
internationally recognized and meets our trading obligations and international
treaties

Oil Palm Industry Biosecurity Plan Protection from risks posed by pests through exclusion, eradication and control
Pre-border • Identifying exotic pest threats • Import conditions and
phytosanitary measures • Managing quarantine risks
offshore (pre-clearance inspection)
• Treatment at point of export where appropriate
Border • Implementing effective
quarantine for people, plants, machinery and goods
• Efficient border controls • Establishing trapping &
surveillance networks for pests that may bypass checkpoints
Post-border • Minimizing risk of regional or
property entry & establishment • Preparing for timely detection,
minimised spread and rapid response to emergency pests
• Continuous surveillance and monitoring
• Farm biosecurity
Achieved through effective partnerships between industry, government and the community
Biosecurity Plan: Risk Mitigation
Biosecurity Plan: Contingency plans
and response management
Detection of a suspected exotic plant pest
By planters, growers, consultants, research personnel, university staff,
agribusiness, staff of MPOB and DOA, general public, etc
Inform State Director of Agriculture and MPOB Technical Officer
Planning for state-wide survey to determine the spread
Inform Director of Plant Biosecurity Division, DOA in Kuala Lumpur for gazetting
as a new quarantine pest
- Planning for execution of contingency plan
- Initiate operation room to monitor developments
- Initiate nationwide survey to determine the status of spread
Key Agencies involved in the development
of the biosecurity plan
Malaysian Palm Oil Board (MPOB)
Plant Biosecurity Division, Dept. of Agriculture
Malaysian Quarantine and Inspection Services (MAQIS)
National Oil Palm Biosecurity Committee
Malaysian Palm Oil Association (MPOA)
Biosecurity Plan outcomes:
• Biosecurity threats identified and entry prevented
• Biosecurity threats eradicated or contained before they become established
• Biosecurity problems effectively managed to minimize their impacts
• Roles of government, industry and the community clearly defined and co-operation to manage biosecurity threats and problems ensured
• Industry capacity in risk assessment enhanced
Is the Oil Palm Industry Safe ?
Steps are currently undertakes to eradicate the pest and prevent its spread to other palm trees besides coconut.

Red Palm Weevil
( Rhynchophorus ferrugineus Olivier )
The red palm weevil (RPW) is a serious pest which attacks
a broad range of palmae, especially date palms, coconut,
sago and the potential to attack oil palm
FARIDAH AINI, M (2016) Biosecurity Workshop, MPOB
• Consists of two species: Rhynchophorus ferrugineus & R. vulneratus (Hallett et al., 2004)
• These two species are morphologically distinct:
• In term of aggressiveness, R. ferrugineus is more invasive:
- Responsible for the current infestation on coconuts in Kelantan and Terengganu
- Due to abundance during trapping activity & palm inspection
Black spots on reddish-orange head
R. vulneratus R. ferrugineus
Vertical red-stripe on black head
Red palm weevil (RPW)
• Severe infestation on coconuts in east coast of Malaysia (Terengganu)
(Wahizatul et al., 2013)
• Also attack others in Palmae family (nibong, nipah, sago, date palms)
• Quick adaptability to new hosts
• Depletion of the host has triggered fear among the oil palm planters
Different stages of RPW attack
CONCLUSION
• The development of the Biosecurity Plan for oil palm
is crucial to ensure exotic pests and diseases could
possibly enter this country
• Various organisations in the country must be aware
and work towards a common goal to ensure Malaysia
remains free from these devastating pests and
diseases.
• For endemic pests and diseases, prevention and
curative treatments are being adopted and
implemented by oil palm industry and smallholders.
