Popis: lt;bgt;Background and Objective:lt;/bgt; Cashew Nut Shell Liquid (CNSL) is a biopesticide that is environment-friendly in controlling antslt;igt;Iridomyrmex cordatuslt;/igt; is a vector pot rot disease caused bylt;igt;Phytophthora palmivoralt;/igt;. The research aimed to obtain the best concentration of cashew nut shell liquid formulated as smart food bait to tackle the ant population oflt;igt;Iridomyrmex cordatuslt;/igt; due mainly to a vector oflt;igt;Phytophthoralt;/igt;pod rot.lt;bgt;Materials and Methods:lt;/bgt; The research was carried out in cocoa areas in South Sulawesi with a randomized block design consisting of six treatments. Feeding trials consisted of food bait formulation that was added with cashew husk, respectively 1, 10, 20% and 17.5 g carbaryl (recommended dose) and control (without cashew husk or carbaryl). Each trial was replicated five times and set near to petiole and ant tunnel nest. The research focused on the number of ant colonies established in the trees until food bait was given.lt;bgt;Results:lt;/bgt; The trial with CNSL concentration had a positive effect on the ant population the higher concentration given, the lower the ant population was obtained. Meanwhile, the population oflt;igt;I. cordatuslt;/igt; had a positive contribution to the increase of disease incidence oflt;igt;Phytophthoralt;/igt; pod rot diseaselt;igt;.lt;/igt; Feeding trials with 1 and 5% CNSL concentrations were less effective to limit ant population and disease incidence according to the efficacy test. In contrast, the trials of 10 and 20% were able to control population density and disease incidence due to over 51.39% efficacy test.lt;bgt;Conclusion:lt;/bgt; There was a positive trend of CNSL concentration to reduce the ant population oflt;igt;I. cordatuslt;/igt;. There was the greatest association between the increase of ant population density and the increase in disease incidence oflt;igt;Phytophthoralt;/igt;pod rot.
