“…Phytophthora palmivora isolates from durian were found to be moderately pathogenic to papaya [235]. In addition, isolates from cocoa could infect durian, rubber, oil palm, and coconut [236][237][238][239]. These studies indicate the possibility of field infection by Phytophthora palmivora in susceptible plants.…”

Minor tropical fruits are grown on a small scale and provide income to smallholder farmers. The cultivation of these fruit crops indirectly contributes to the economy of producing countries as well as to food and crop security. Dragon fruits, guava, passionfruit, lychee, longan, mangosteen, durian, and rambutan are common minor fruit crops. In recent years, the international trade of some of these minor tropical fruits, particularly dragon fruit, passionfruit, guava, and lychee, has increased due to their nutritional value, with various health benefits. Similar to other crops, minor fruit crops are susceptible to fungal and oomycete diseases. These diseases negatively affect the yield and quality of fruit crops, leading to substantial losses. In this context, the knowledge of disease types and causal pathogens is fundamental to develop suitable disease management practices in the field as well as appropriate post-harvest treatments.

“…Phytophthora pod rot disease caused by Phytophthora palmivora is one of the most dangerous global cocoa diseases and in Sulawesi, the disease is more rampant with a much greater impact than any kinds of biological cocoa pests and diseases [5][6][7][8] . The wet season is one of the main causes behind the disease prevalence since the range of ripening time and peak harvest is almost rainy season 9,10 .…”

“…A preliminary study was undertaken to show specific lesion occurrence once the body of I. cordatus was attached to a fresh pod 2,4 . The main reason behind of effectiveness of Phytophthora pod rot disease spread was due to tunnel nest of ant built from organic matters which is contaminated by spores, connecting niche and pathogen and providing inoculum sources of Phytophthora pod rot disease 8,11 . The pathogen infects all stages of cocoa pod development and if attacked immature pod leading to Cherelle wilt 11,14 .…”

Background and Objective: Cashew Nut Shell Liquid (CNSL) is a biopesticide that is environment-friendly in controlling ants Iridomyrmex cordatus is a vector pot rot disease caused by Phytophthora palmivora. The research aimed to obtain the best concentration of cashew nut shell liquid formulated as smart food bait to tackle the ant population of Iridomyrmex cordatus due mainly to a vector of Phytophthora pod rot. Materials and Methods: 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. Results: 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 of I. cordatus had a positive contribution to the increase of disease incidence of Phytophthora pod rot disease. 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. Conclusion: There was a positive trend of CNSL concentration to reduce the ant population of I. cordatus. There was the greatest association between the increase of ant population density and the increase in disease incidence of Phytophthora pod rot.
