Abstract

Spodoptera pectinicornis is a biological control agent that has a great potential to control water lettuce weeds. Its existence in nature however is still limited, so a mass propagation is needed by rearing S. pectinicornis imagoes to produce eggs and to hatch them into larvae of 4 days old. The 4-year larvae were then released by putting water lettuces that contained active larvae into the target area. Observation results on the percentage of damage in the watershed location for 5 times of observation consecutively was 25%, 50%, 50%, 75% and 90%. The magnitude of damage showed that S. pectinicornis was able to adapt well, so it could perform eating activities and cause damage to the water lettuces. Meanwhile, at the release site of rice field, the percentage of damage was 0%, 25%, 35%, 25% and 10%. The downward trend in the level of S. pectinicornis attacks was due to its inability to keep pace with the growth and development of water lettuces. High level of rainfall caused the water lettuces to increase its size and the number of its tillers so that they could colonize these waters. The fact that S. pectinicornis still has the ability to destroy the water lettuces gives great hope to the control efforts. However, thorough evaluation and assessment are required on all aspects, such as the biological control agents, weed targets, organisms associated with them, and the state of the environment so as to minimize the possibility of failure in the field. Keywords: augmentation, biological agents, Pistia stratiotes, Spodoptera pectinicornis

Abstract

Rigidoporus Sp. is a white root fungus which is the main diseases problems on rubber plants in the wet and dry lands of South Kalimantan. An economically and ecologically beneficial control solution for this problem soil contagion was by using antagonistic fungi. This research was aimed to study the potential of rhizosphere and endophytic fungi in swampland, to control white root fungus on rubber plants. The research used exploratory method. Rhizospheric fungi were explored from swamp rubber plant roots at Pulau Damar village Hulu Sungai Utara District; endophytic fungi were isolated from leaves and jelutung swamps (Dyera lowii) which is rubber-like plants. The isolates found then were screened based on the percentage of inhibition using the dual culture method between pathogens and test isolates, also observed the interaction mechanism and viability test. The research in the laboratory was arranged using a Completely Randomized Design with one factor i.e. the type of antagonistic fungi. Five isolates which had the highest inhibitory power were isolates I13K4R, I7K3R, I1K2R, I6K2R, and I1E with successive inhibitions 95.00%, 83.00%, 76.50%, 62.50% and 53.00%. Thus, isolates have included potential antagonistic agents because they had the ability in space competition more than 50% and proven to be able to paralyze Rigidoporus. The viability test results showed that the isolate that had germination capability of more than 60% were respectively I13K4R 88.05%, I7K3R 87.33%, I1K2R 86.93%, I6K2R 72.85%, and I1E 74.78%.
