Mango is one of the commercially important fruit crops in the Philippines. Mango is prone to attacks of insect pests and diseases in all stages of development. One management practice which can help address these problems is fruit bagging because it is another way of preventing contact between the host and insects/diseases as well as minimize mechanical injuries thus improving quality. The project aimed to determine which of the bagging materials and forms gave the best quality of fruits, determine the effect of the bagging materials and forms on pest incidence, and find out which of the bagging materials and forms gave the highest yield and net income. The project was conducted at the Integrated Sustainable Agri Techno Demo Farm of the Pangasinan State University, Sta. Maria Campus, Sta. Maria, Pangasinan: Study 1 - Bagging materials (white plastic bag, black polyethylene bag, brown paper bag, glossy paper bag and newspaper bag); and Study 2 - Bag forms (Triangular/Marsman style, Flat form/Cebu technology, Modified square form, and conical form). There were 16 experimental trees split into four blocks, in each block there were four trees and in each tree all the treatments were present in each study. Fruits were bagged at 46 days from the last spraying of KNO3. Each treatment had 10 sample fruits bagged. Sampling was randomly done. Brown paper bag, white plastic bag and glossy paper bags and triangular/Marsman style, flat/Cebu technology and modified square as bag forms securely protected the mango fruits against pest incidence. Fruit bagging with brown paper bag and triangular bag/Marsman style exhibited the highest ROI. However, a verification study along this line for a more conclusive result is recommended.
