Southeast Asia Site in the Philippines

IPM activities in the Philippines site were concentrated in four program areas. Research focused on on-farm pest management experiments; multidisciplinary laboratory, greenhouse, and microplot experiments; IPM […]

Integrated Weed Management Strategies in Rice-Onion Systems

This project examined how tillage, in the form of stale-seedbedtechniques before planting onion, can reduce tuber and shoot populations and reduce the need for postplantweeding, which […]

Parasitoid Abundance, Incidence of Larval Parasitism, and Effect of Trap Color on Attraction to the Onion Leafminer, Liriomyza trifolii(Burgess)

Onion farmers in the Philippines apply a large amount of insecticides against leafminers hoping to effectively manage this pest below damaging levels. Researchers believed that the […]

Influence of Host Resistance and Grafting on the Incidence of Bacterial Wilt of Eggplant

One of the problems in the management of the bacterial wilt disease of eggplant is the lack of basic information on the diverse nature of the […]

Combined Resistance of Eggplant (Solanum melongena L.) to Leafhopper (Amrasca biguttula Ishida) and the Eggplant Borer (Leucinodes orbonalis Guenee)

This project sought to address IPM constraints including lack of available sources of resistance to the cotton leafhopper and few eggplant germplasm sources resistant to the […]

Management of the Eggplant Fruit and Shoot Borer, Leucinodes orbonalis (Guenee): Evaluation of Farmers’ Indigenous Practices

Eggplant farmers in the Philippines spray insecticides up to 58 times during the crop period. Insecticide spray is mostly directed to the fruit and shoot borer. […]

Management of Anthracnose (Colletotrichum gloeosporioides) (Penzig) Penzig and Sacc., a Disease of Increasing Importance in Onion

Researchers conducted a field study at PhilRice Central Experiment Station in Maligaya, Science City of Munoz, Nueva Ecija to develop integrated management strategies against anthracnose of […]

Management of Spodoptera litura (F.) and S. exigua (Hubner) in Onion Mass Trapping and Timing of Interventions in Farmers’ Fields

This project focused on evaluating the effect of mass trapping of male S. Litura and S.exigua moths with sex pheromone trap catches and the effects on […]

Effect of Defoliation at Different Crop Ages on Yield of Onion

Researchers conducted a study to determine the effect of totally cutting off different numbers of leaves at different crop ages on bulb size and weight of […]

Biological Control of Soil-Borne Pathogens Using Trichoderma spp.in Rice-Vegetable Systems

This research focused on evaluating the effectiveness of biological control agents against soil -borne pathogens of onion.
