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.

Management of Soil-borne Diseases of Onion with Selected Biological Control Agents and Soil Amendments

This study examined the effects of vesicular arbuscular mycorrhizae (VAM) alone, in combination with organic manures, and in comparison with other growth-promoting materials on root-knot and […]
