“…Currently, biological control agents for plant disease control have been widely reported, including Bacillus subtilis, B. cereus, Trichoderma spp., and Gliocladium sp. [12][13][14][15]. Considering that the ability of each endophytic microbe is very diverse, the search and identification of the ability of isolates to suppress the development of pathogens are still being carried out.…”

The use of synthetic pesticides to increase maize production sustainably contributes to increasing the development of pathogens and tends to be less effective in environmental conditions that support pathogens. In addition, the emergence of environmental pollution due to the use of chemicals causes the need for environmentally-friendly control technologies. Endophytic microbes are biological agents that can be used to plant disease control that is environmentally friendly and practical in their application. The study aimed to detect pathogenic bacteria that cause wilt and blight in maize and then examine the potential of several endophytic microbial isolates in controlling Stewart wilt pathogens in maize in vitro. The research was carried out from February to July 2021 at the Cereal Crop Research Institute Laboratory in Maros for morphological identification and microbial potential testing, while serological tests were carried out at the Makassar Plant Quarantine Laboratory, South Sulawesi. The study began with detecting pathogenic bacteria serologically using the Enzyme-Linked Immunosorbent Assay (ELISA) method. The results showed that blight symptoms on corn isolated from the experimental garden of IP2TP Bajeng Gowa Regency PS-4 and PS-5 were detected as bacteria Pantoea stewartii subsp. stewartii. The antagonistic test of endophytic bacterial isolates I.A1, II.D1, III.A2, IV.B2, and endophytic fungi isolates AC-1, AC-3, and DC-5 was able to suppress the growth of pathogenic bacteria isolates PS-4 and PS-5 The growth suppression of pathogenic bacteria was observed by forming inhibitory zones of antibiosis compounds. Pathogenic bacteria Pantoea stewartii subsp. stewartii can be controlled using endophytic microbes.

Mealybugs, Planococcus sp. (Hemiptera: Pseudococcidae), are the secondary pest on the cacao plant. However, this pest often infested cacao shoots in the nursery and causes the death of the seedling. Pest control efforts use existing materials plants in Indonesia and are relatively easy to make and adopt by stakeholders. The purpose of this research was to screen the efficacy of some plants extracts against mealybugs on cacao. We researched in the laboratory of pests and diseases, IIBCRI. Mealybugs were collected from cacao plantations and reared in the laboratory. The materials plants used for extraction were Cassia spectabilis leaves, Gliricidia sepium leaves, Cinnamomum burmannii leaves, Allium sativum bulbs, Reutealis trisperma fruits, and Cymbopogon nardus leaves. The methods were spraying the plant extracts on mealybugs directly (KS) and cacao pod (BS). The results showed that all types of oils at a concentration of 5% in the KS and BS methods could kill mealybugs equivalent to deltamethrin. The smallest value of LC50 3 DAT is at the MSW (KS), while at 7 DAT, LC50 7 DAT is at MDG (BS). The fastest LT50 value is at MSW (KS) 5%, while in the BS method, the fastest LT50 value is on the MBKS 5%.
