The severity of plant disease is closely related to the development of the disease itself, including rusts caused by pathogenic fungi. This research aimed to determine the difference of rusts disease severity and to determine the correlation between rusts disease severity with the productivity of different varieties of soybean. The material used was inoculum of rusts pathogenic fungi, Phakopsora pachyrhizi Syd., and four varieties of soybean, i.e., Slamet, Lokon, Bromo, and Ringgit. This research was a split-plot design experimental with subplot was four different varieties of soybean, and the main plot was the control without the treatment of inoculation (In0). The spores suspension density of inoculum of P. pachyrhizi Syd applied was 104 spores/ml (In1). The main parameters observed in this study were the height of plants, the number of pods per plant, the number of seeds per plant, the wet and dry weight of the plant, and the total weight of 100 grains seed. The supporting parameters were the disease severity, the soil acidity, the humidity, and the air temperature. The results showed the plant with lowest rusts disease severity was Slamet variety (18,38%), and the highest was Ringgit variety (35,92%). The correlation test showed the increment of rusts disease severity reduced the number of pods and dry weight of the plant in Lokon variety.

EFEKTIVITAS PELET BIOFUNGISIDA Trichoderma harzianum MENGENDALIKAN Fusarium sp. PENYEBAB PENYAKIT REBAH SEMAI PADA BIBIT TANAMAN CAISIM (Brassica rapa var. parachinensis L) Rubiati Fadhilah; Juni Safitri Muljowati; Endang Sri Purwati

This research aimed to determine the effect of the interaction of the dosage with the application model of Trichoderma harzianum bio-fungicide pellet to the effectiveness of damping-off disease control caused by Fusarium sp. on the green mustard, and also to determine the most effective dosage and application model to control that disease. This research was experimental with the factorial completely randomized design. The factors were: the dosage of T. harzianum bio-fungicide pellet, i.e., 0 g (D0), 12,5 g (D1), 25 g (D2), 37,5 g (D3), 50 g (D4), 62,5 g (D5), and 75 g (D6); and the application model of pellet, i.e., T1, T2, T3 dan T4. This research analyzed the data using the test of variety difference with 5% and 1% degree of errors, followed by least significance difference test. The results showed the interaction between dosage and application model did not affect the effectiveness of the damping-off disease control on the green mustard seedling. The dosage of T. harzianum pellets and the application model of T. harzianum pellets independently gave a significant effect on the effectiveness of biological control agent of T. harzianum toward Fusarium sp. on the green mustard seedling. The dosage of 37,5 g per 50 green mustard individuals was the most efficient amount to control the damping-off disease. The 7-day continuous application and incubation of pellet to the seeding medium before pathogen inoculation and planting were better than any other application models.

KORELASI KARAKTER ANATOMI DAUN UBI JALAR (Ipomoea batatas L.) KULTIVAR TAHAN DAN TIDAK TAHAN TERHADAP INTENSITAS PENYAKIT KUDIS DAUN Ade Winda Pradana; Siti Samiyarsih; Juni Safitri Muljowati

Sweet potato (Ipomoea batatas L.) is one of alternative food sources beside than rice. Sweet potatoes are contains minerals, nutrients, sources of energy, protein, vitamins A and C. Sweet potatoes have lower productivity than rice and cassava. The low productivity of sweet potatoes due to several factors, which one of them is a leaf scab disease caused by pathogens Sphaceloma batatas Saw. The purpose of this study is to determine the character of the anatomy of sweet potato leaf cultivars that resistant and unresistant to the intensity of leaf scab disease, as well as the correlations between the anatomy character of sweet potato leaves with leaf scab disease intensity. The method used in this study is an experimental method with factorial completely randomized design. The first factor is the character of the anatomy of four cultivars sweet potato leaves, Cangkuang and Sukuh cultivars (cultivars resistant), cultivars Cilembu and Beta (unresistant cultivars). The second factor is the inoculation treatment S. batatas Saw. The parameters were observed thickness of cuticle, epidermis, mesophyll, the size (length and width) stomata, density of stomata and trikomata as well as the intensity of the disease were analyzed using analysis of variance (ANOVA). To determine the correlation between the anatomy character leaves with disease intensity using regression correlation analysis. The results showed that Cangkuang cultivar has cuticle, epidermis and mesophyll thickest. Beta cultivars have stomata size of the longest and widest. Cilembu cultivar has the highest density of stomata. Sukuh cultivars has the highest density. The anatomy characters include of a thick cuticle, epidermis, stomata size (length and width), as well as the density of stomata and trikomata correlated with intensity of leaf scab disease.
