Efficacy of selected Trichoderma isolate and organic matter to control foot rot of black pepper in the field.Â The objective of this experiment was to determine the efficacy of selected Trichoderma isolatand organic matter to control the disease. Dual culture method was used to select a Trichoderma isolate. The experiment to evaluate the efficacy of selected isolate consisted of control (no application of T. harzianum or organic matter), T. harzianum and rice straw, and T. harzianum and coffee husk. As starter, T. harzianum was grown in broken rice. Two liters of organic matter was infested with suspension of 10 g starter in 100 ml steril water and incubated for 2 weeks. The mixture was applied around the base of black pepper stem. The results showed that all plants treated with T. harzianum and organic matter did not show disease symptom. Ten percent of the control plants showed symptoms. However, statistical analysis showed that the occurrence of the disease was not significantly different between treatments. Applications ofT. harzianum and rice straw increased the density of Trichoderma for 1 and 2 months after application. T. harzianum and coffee husk increased the density of the fungus 1 month after application.

Epidemic Components of Sugarcane Root and Basal Stem Rot In South Sumatra Root and basal stem rot disease is one of new disease that currently was became a emerging problem on sugarcane plantations in Lampung and South Sumatra. The research was aimed to study the model of disease progression, AUDPC, infection rate (r), and the influence of weather and soil condition (physical and chemical properties of soil) on the development of sugarcane root and basal stem rot disease. The research was conducted on sugar cane plantation in South Sumatra. The disease incidence in three varieties was observed weekly in the field which had infected plant in previous year.. The data were analyzed to develop model of the disease progression, AUDPC, and the rate of root and basal stem rot disease. Weekly weather data was acquired from weather station of Sultan Mahmud Badaruddin Airport, Palembang. Soil sample was taken from three disease category i.e moderate (disease incidence 25,1% - 50%), severe (disease incidence 50,1% - 75%), and healthy (no disease). The results showed that the disease develops following monomolecular and logistic models. The AUPDC and infection rate (r) in the monomolecular model were lower than in the logistic model. The direct effect coefficient of rainfall and relative humidity (RH) on the disease were positive (1.27 and 0.46 respectively), contrary the temperature and duration of irradiation which had a negative coefficient (-0.33 and -0.45 respectively). Meanwhile, K availability and permeability give a positive effect on the disease, while the total N and Fe availability give a negative effect on the disease.

Ganoderma root disease in the community forest of sengon is one of the limiting factor to increase the productivity of sengon wood. This disease has been reported in West Java, East Java, South Sumatra and South Kalimantan. The survey was conducted to determine the existence of Ganoderma root disease in three sengon fields in Sleman, Yogyakarta. The existence of Ganoderma root disease was recognized based on the symptoms of diseased plants and the present of Ganoderma basidiocarp on the diseased sengon stem. The survey results on three sengon fields was succeed in finding diseased plants and also the basidiocarp of Ganoderma on the basal of the diseased plant stem. Symptoms that have been found was either dead or dying trees (few leaves left). The basidiocarp of Ganoderma on the diseased plants varies in characteristic while its young and mature. The basidiospores is ellipsoid, truncate, rough (coarsely echinulated), and double-walled. The Ganoderma colony was white and turned to yellow orange from the center. Based on this study the Ganoderma root disease in sengon plants has developed in Sleman, Yogyakarta. The presence of dead or dying trees with few leaves left between healthy sengon trees and the presence of Ganoderma basidiocarp in diseased trees are indicator of the presence of root disease in the sengon field caused by Ganoderma.

Foot rot of black pepper (Piper nigrum L.) caused by Phytophthora capsici Leionian is commonly considered as one of the most important problems in black pepper production. The objectives of this research was to determine the influence of organic matter and Trichoderma spp. on the severity of foot rot of black pepper. On the first experiment, five Trichoderma mycelial plugs were applied on planting medium consisting of soil, organic matter, and sand (2:2:1, v/v), then incubated for 7 days. Black pepper plants were transferred to the planting medium and after 14 days were inoculated on the stems. The variable observed was disease severity on the stem. On the second test, Trichoderma that was grown on broken rice (menir) as starter was applied into the planting medium which consists of soil and sand (2:1, v/v). Two weeks later, black pepper plants were inoculated on the leaves and stems. The variables observed were the diameter of necrotic on the leaves and disease severity on the stem. On the first experiment when 15 isolates of Trichoderma spp. were tested, five isolates (T. harzianum isolates 6, 8, 9, 10, and 15) significantly reduced disease severity. However, on the second test when four out of the five effective isolates were retested, none was found to significantly reduce disease severity on leaves or stems.

The objective of this research was to determine the influence of the kinds of organic matter on the efficacy of Trichoderma harzianum Rifai to control foot rot of black pepper caused by Phytophthora capsici Leonian. Trichoderma spp. were isolated from suppressive and non-suppressive soils taken from black pepper fields with high disease incidence. Screening of Trichoderma spp. isolates was conducted through antagonistic test with dual culture technique. Treatments were arranged in a completely randomized design with six replications. Treatments were rice husk, rice straw, wood dust, Arachis pintoi, mixture of the four organic matters, the mixture without T. harzianum, and without organic matter. The test was conducted in greenhouse with media consisted of soil, organic matter, and sand (2 : 2 : 1, v/v). After being otoclaved, the medium was infested with T. harzianum and P. capsici each with five mycelium plugs of 1-cm diameter. Black pepper seedlings were planted 5 days after fungal infestation. After planting the seedlings, five leaf cuts were partly inserted into the soil on each pot. The variables observed were disease incidence on the leaf cuts inserted into the soil and disease severity on the stems and roots. The results show that all 16 Trichoderma isolates inhibited P. capsici colonies and some isolates showed stronger inhibition than the others. T. harzianum reduced disease severity, but there was no effect of the kinds of organic matter on the ability of T. harzianum to control foot rot.
