The Crop Pest Management Division is the agency's arm tasked to administer crop pest management services anchored on optimization of crop harvests for greater food and economic sustainability. It traces its roots way back in 1932, upon the promulgation of Act No. 4007, known as the Reorganization Law of 1932, creating the Plant Sanitation Division.

The Division underwent several reorganizations. On April 1952, during the Third Republic, it was named as the Plant Pest and Disease Control Division.The Division took the name Pest and Disease Control Division by virtue of Reorganization Plan No. 30-A, as implemented by Executive Order No. 216, implemented on January 16, 1957. It became the Crop Protection Division under the Integrated Reorganization Plan of 1972, until it assumed its present name as mandated by the government's most recent reorganization plan.

• Technical Assistance – to clientele, peers, and the general public in the identification and management of crop pests, serve as resource speakers on different crop pest management topics, hands-on training on mass production of biological control agents
• Pest Clinic – inquiries regarding insect pests, diseases, rodents and weeds, these are identified, preserved and management recommendations are given to the clienteles

TECHNOLOGY

• Trichogramma – egg parasitoid utilized as biocon agent to control asian corn borer (t. evanescens), rice stemborer (t.japonicum) and vegetable lepidopterous pest (t. Chilonis)
• Metarhizium – green muscardine fungus used as bioagent versus rice black bug, rhinoceros beetle of coconut, coconut leaf beetle, etc.
• Chilocorus nigrita – primarily feeds on the family Diaspididae namely; Aspidiotus destructor (armoured scale) on coconut andLepidosaphes ulmi (mussel scale) on lanzones but also has been reported to feed on whiteflies, aphids and psyllids.
• Trichoderma – most common fungal antagonist and used as compost fungus activator
• Lacewing – preys on aphids, thrips, mealybugs, whiteflies, armyworm, budworms, bollworms, borers, corn earworms, scale insects, psyllids, etc.
• Telsimia nitida - feeds on Aspidiotus destructor (armoured scale) and Lepidosaphes ulmi (mussel scale)
• Earwig – (Chelisoches morio) feeds on coconut leaf beetle Brontispa longissima; (Euborella annulata) feeds on corn borer and insect pests of vegetables
