“…The Maja Cipanas shallot showed the highest plant height, but not really different from the Ambassador and Bima varieties. The difference in plant height on variety is the morphological adaptability [16]. Meanwhile, the aplication time of Trichoderma did not significant statistic to affect plant height, However, looking from the average numbers of observations, Trichoderma applied before planting plus applied again after two weeks shows the highest result in plant height (Table 1).…”

Soil-borne diseases in shallots are the main diseases that can cause weight loss, especially for seeds. One of the biological agents that can control the disease is Trichoderma sp. So far, the use of Trichoderma often does not seem effective because the application time is not right. Trichoderma already exists and grows outside and inside plant tissues. This is due to the nature and character of Trichoderma for its antagonistic fungus that competent to colonize the rhizosphere quickly and protect roots from pathogen attack. This study aims to determine the interaction between the application time of Trichoderma sp and varieties on growth and disease development for seed production. The research was carried out at the Margahayu Experimental Garden, Institute Vegetable Research Indonesian (1,250 m.asl), from September to December 2021. The experiment used was a factorial randomized block with two factors and three replications. The first factor is the time of application of Trichoderma (without Trichoderma, before planting, before planting + 2 weeks after planting, and before planting + 2, 4 weeks after planting). The second factor is several varieties of shallots (Violetta, Ambassador, Maja Cipanas, Bima and Trisula). The results showed that there was no interaction between application time and variety on growth, disease attack, and yield of shallot bulbs for seed. However, application time and varieties affected the intensity of the disease of Stemphylium vesicarium and Peronospora destructor. Maja Cipanas showed the highest plant growth (plant height, number of leaves and number of tillers) with dry weight, weight of one month of storage and weight of two months of storage per clump each of 60.19 g; 50.27 g and 39.49 g.

This study aimed to evaluate the effect of clove oil to control pathogens associated with tomato plants in screen houses. The study was carried out using a completely randomized design (CRD) with 5 treatments repeated 3 times and each treatment consisted of 3 plants for a total of 45 plants, the treatments given were P0 (without application), P1 (pathogenic fungus Sclerotium sp. without clove oil application). , P2 (pathogenic fungus Sclerotium sp. with clove oil application), P3 (pathogenic fungus Helminthosporium sp. without clove oil application), P4 (pathogenic fungus Helminthosporium sp. clove oil application). The variables observed were plant height, stem diameter, number of branches and disease severity of tomato plants. The results showed that clove oil was able to increase plant growth as indicated by the highest average height and diameter of 18.61cm and 0.31cm, respectively. Clove oil application also suppressed the development of the pathogen Sclerotium sp. As indicated by the average incubation period and disease severity 18.67 days and 6%, respectively.

Rahim et al (2012) melaporkan bahwa intensitas serangan penyakit HDB pada beberapa kultivar komersial di Sulawesi Tenggara berkisar antara 31-69% dan peningkatan laju infeksi pada fase generatif. Kehilangan hasil akibat penyakit ini dapat mencapai 70-80% di musim hujan (Kadir, 1999) bahkan dapat mengalami puso (Tasliah et al, 2013).…”

Rice (Oryza sativa L.) is a rice-producing food crop commodity that plays an important role in Indonesia's economic life. One of the superior varieties cultivated by farmers in Southeast Sulawesi is the Mekongga variety. Xanthomonas oryzae pv oryzae (Xoo) causes bacterial leaf blight (BLB) in lowland rice which is the main disease of lowland rice in Indonesia. This study aims to determine the symptoms of bacterial leaf blight, the characteristics of the Xoo bacteria, and the intensity of bacterial leaf blight attack on rice plants. The observed variables in the study were symptoms, characteristics, intensity of attack by bacterial leaf blight. Research data were analyzed by descriptive analysis. Symptoms of bacterial leaf blight in the field were found to show symptoms that appeared in the form of gray spots on the tips of the leaf edges. The characteristics of the isolates growing on the media had round, mucoid and yellow bacterial colonies. The severity of HDB disease in lowland rice of the Mekongga variety in Konda Konawe Selatan District reached 28.72% with an infection rate of 0.0050 units/day.
