Comparative Efficacy of Different Pesticide Residue Mitigation Modules in Mango | Biomedgrid

A study was conducted at different locations of Multan from March 2016 to April 2017 in which 4 IPM modules were devised for mango in comparison with the control, with the focus of pesticides residues mitigation and maximum yield. Pesticides residues mitigation module (PRMM) were based on the IPM tactics to suppress pest population with no or minimum use insecticides. Each module was applied in an area of 1 acre of mango orchard and pest population was monitored before and after the application of the modules. After the season of the mango was completed the yield was compared of all the modules and yield loss was also calculated in terms of fruit quantity and fruit quality. It was observed that the orchard which was grown under PRMM-2 showed maximum reduction in pest population calculated as much as 92.66% followed by PRMM-1 which was accounted for 86.13% reduction in pest population [1-5]. PRMM-3 reduced the pest population up-to 77.97% followed by PRMM-4 which reduced the pest population to level of 71.43% over control. So, the best results in terms of pest reduction were observed in PRMM-2 which included spray of pesticides along with the use of cultural, mechanical, and attract and kill methods for the mango pests. This module outperformed the chemical method by 21.23% better in terms of pest population reduction while only IPM module with no pesticides used, pest reduction was 14.7% over chemical control methods which are in common practice by most of the farmer community in the country. PRMM-2 produced 25.29% more marketable fruits in comparison of control module while PRMM-1 produced 21.17% more marketable fruits over control. In case of PRMM-3 and PRMM-4 the percentage of surplus marketable produce over control was calculated as 17.21% and 11.47% respectively.
