Ecologically-Based Participatory IPM for Southeast Asia Philippine Site (PhilRice) HRapusas, GS Arida, SSantiago, BPunzal and J Ramos Slide 2 Title of Study: Management of the common cutworm, Spodoptera litura with Sex pheromone and NPV Objective of the Study To develop a management strategy for Spodoptera litura in onion with sex pheromones for effective timing of interventions using NPV. Slide 3 Materials and Method Two farmers fields in Sto. Domingo and Guimba, Nueva Ecija. In each field, two water-oil sex pheromone baited traps were installed 2 weeks after transplanting. Trap catches were recorded 3 times a week and traps were cleaned whenever necessary. The synthetic pheromones were replaced after 30 days. Number of larvae and percentage damage leaves were monitored every week on 20 randomly selected plants per plot. Yield was recorded in 1sq.m. per plot. Treatments: T1- Farmers practice T2- Spray NPV at 5 and 7 days after peak in trap catches T3- Spray NPV at 7 and 9 days after peak in trap catches T4- Spray NPV every week from 14 days after transplanting Each plot measures 4x5m, replicated four times in a randomized complete block design.

Slide 9 Title of study: Effect of rice straw mulch on the population of weeds and natural enemies of insect pests of onion Objective To determine the impact of rice straw mulch on weed and population of beneficial organisms in onion. Slide 10 Slide 11 Slide 12 Slide 13 Slide 14 Slide 15 Title of the Study: Effect of Pre- harvest Application of VAM and Trichodermasp. (CRSP isolate) on the Shelf Life of Onion Objective To evaluate the effect of using VAM and Trichoderma sp. (CRSP isolate) on the shelf life of bulb onion. Slide 16 Research Methods Site of the study: Guimba, NuevaEcija. Onion variety used was Red Pinoy. Treatments : T1-VAM + Trichodermasp. at transplanting T2-farmers practice ( No VAM, No Trichoderma sp) All treatments were treated with the same practices for insect pests and weed management. Disease incidence, disease severity and yield were collected. After harvesting leaves were trimmed at 2 inches above the bulb. Onion bulbs were allowed to cure for a month in a ventilated area. After curing, bulbs were placed in mesh bags with a capacity of 5kg/bag and were stored at room temperature (27 0 C). Weight loss and occurrence of bulb rot disease were observed and recorded bi-weekly for four months. Slide 17 Slide 18 Slide 19 Slide 20 Slide 21 Slide 22 Development of Alternative Storage Techniques to Prolong Storage Shelf Life of Onion Objective To develop storage techniques to reduce postharvest losses due to diseases and prolong bulb storage. Slide 23 Research Methods Site: Bunol, Guimba, Nueva Ecija. Red Pinoy onion variety was used in this study. Samples were harvested from the plots treated with VAM + Trichoderma sp. before transplanting (IPM plot) and from the farmers practice plots. After harvesting at 90 DAT, the leaves were trimmed to 2 inches above the bulbs and allowed to cure for 2 weeks in a ventilated area. After curing and treatment application, onion bulbs were placed in mesh bags with a capacity of 5kg/bag and were stored at room temperature (27 O C ). Treatments: T1 - Onion dusted with Trichoderma sp. + Carbaryl T2 - Onion dusted with Mancozeb + Carbaryl T3 - Onion dusted withCarbaryl alone Percentage of weight loss and bulb rots was taken and recorded bi-weekly for four months.
