Effectiveness of the application of organic matter and Trichoderma viride from suppresive soil to control fusarium wilt on banana plant. Fusarium wilt disease caused by Fusarium oxysporum f.sp. cubense is one of the problems in banana production. This research was aimed to evaluate the effect of  Trichoderma viride isolated from suppresive soil and organic matter on controlling fusarium wilt on banana plant. The efficcacy trial consisted of 12 treatments and four replications within each treatment. Each experimental unit consisted of 10 plants. Organic matters used were rice straw, cassava peel, and compost. Treatments were arranged in a randomized complete block design. Data obtained were analyzed by analysis of variance followed by orthogonal analysis (P≤0.05). Application of T. viride suppressed disease incident up to 65%. The highest disease incident occurred in plants treated without T. viride and organic matter and in plants treated with organic matter only (78.33%). Disease incidence in plants treated with T.viride was lower than those treated with the combination of T. viride and organic matter. Different application times (in nursery or soil medium) did not significantly affect fusarium wilt incidence. The type of organic matter did not significantly affect the incidence and severity of fusarium wilt.

The aims of the research were to determine the best organic matter as carrier for growth and increasing the density of Trichoderma viride strain TV-T1sk (TV-T1sk) and its influence on Fusarium wilt disease development on banana seedling.  This research consisted of two experiments, i.e. (1). Growth  testing of TV-T1sk  in various organic matter, (2). Various organic matter testing for increasing the density of TV-T1sk in banana rhizosphere and its influence on  Fusarium wilt desease development.  The treatments were various organic matter, namely rice straw, sugar cane pulp, rice bran+banana plant waste,  hull of rice+sugar cane pulp and rice. The variables observed were  density and viability of conidia on various organic matter. Propagule density after introduction to banana rhizosphere was determined by observing TV-T1sk propagul from the rizosphere of banana seedling. The influence of density on Fusarium wilt disease development was determined by incubation period, the percentage of symptomized leaves and the intensity of corm damage. The results showed that both sugar cane pulp and rice were the best organic matter  for increasing  the growth and the density  of TV-T1sk  after introduction to banana rhizosphere. The density of TV-T1sk propagule on banana rhizophere influenced  the development of Fusarium wilt disease.

Clubroot Disease

Club root is one of the most important diseases in the eastern hills of Nepal affecting the rural income as well as quantity and quality of Cauliflower production. A field experiment was conducted in Randomized Complete Block Design (RCBD) with 5 treatments and 4 replications during February to May, 2019. The experiment was conducted in the Farmer’s field in the disease prone area of Thaha municipality-4, Palung of Makwanpur district to assess the efficacy of five different treatments; Nebijin, Hatake, Trichoderma viride, Lime and control for the management or suppressing the club root disease. The effectiveness of the treatments against club root disease was evaluated along with their influence on growth parameters and yield parameters of white top variety of cauliflower. Different parameters such as disease incidence, percent disease index (PDI) or disease severity index (DSI) and percent disease control (PDI) were recorded using disease scoring scale. The treatments showed significant effect on the yield and disease parameters, but not on the vegetative parameters of cauliflower. The lowest disease incidence (50.2%) and severity index (26.8%) and the highest percent disease control (57.6%) was recorded in Nebijin. Moreover, the Marketable yield (Mtha-1) per plot was observed highest from Nebijin (48.27Mtha-1) and Trichoderma viride (47.39 Mtha-1) treatment. From the study it may concluded that the application of Nebijin was more effective for the management of clubroot disease of Cauliflower and the use of Hatake and Trichoderma virideas bio-fungicides were also giving the potential assuring measure for the controlling disease of Cauliflower.

This study evaluated the forage mass, plant height, chemical composition and chlorophyll index of signal grass (Brachiaria decumbens cv. Basilisk), as well as the content of organic matter (OM) in soil under increasing levels of nitrogen. The experiment was conducted in the Rio Manso Farm, experimental unit of the Federal University of the Jequitinhonha and Mucuri Valleys - UFVJM in the municipality of Couto de Magalhães de Minas, state of Minas Gerais. For plant evaluation, we use a split plot randomized block design with four replications. Nitrogen levels (0, 25, 50, 75, 100 kg ha-1 N) were assigned to plots and the cuts made in plants, to subplots. For the assessment of soil organic matter, we used a split-split-plot, with nitrogen levels (0, 25, 50, 75 and 100 kg ha-1 by cut) in the plots, collection depth (0-10 and 10-20 cm) in the subplots and three sampling times (before the onset of the experiment, at the end of the 1st crop year and at the end of the 2nd crop year) in sub-subplots in a randomized block design with four replications. It can be concluded that nitrogen fertilization linearly increases forage mass, plant height and crude protein content of signal grass, which are positively correlated with chlorophyll index. At the end of two agricultural years, the content of organic matter in the soil decreases, which can be attributed to management of cutting and removal of the cut material.

Downy Mildew Disease

Downy mildew (Pseudoperonospora cubensis) is one of the most important disease of cucumber under open field conditions. Hence, the experiment was conducted to study the efficacy of fungicides in management of downy mildew disease of cucumber (Cucumis sativus L.) under open field in Chauradi-7 Dhading during spring season, 2019. Bhaktapur local variety of cucumber was used for the study. The experiment was laid out in single factor randomized complete block design with four replications. Three different bio-fungicides; Trichoderma viride + Trichoderma harzianum, Bacillus subtilis, Verticillium lecanii and one chemical fungicide; Krilaxyl (metalaxyl 8% + mancozeb 64%) were used as treatments. Normal water spray served as control. It was observed that bio-fungicides had insignificant effect in controlling the downy mildew. Pathological observation such as disease incidence percentage, severity percentage and AUDPC in bio-fungicides treated plots were not significantly different from water-sprayed control plots. Similarly, biometric attributes such as number of fruit, length and diameter of fruit, weight of fruit were also non-significant. Krilaxyl resulted significant effect in controlling downy mildew, providing maximum disease reduction (37.48%-50.72%) with lowest disease incidence (1.25-61.25%) and lowest value of AUDPC (138.7). Krilaxyl treated plots had higher number of fruit (6), longer length of fruit (17.15-18.95), higher diameter of fruit (4.16- 4.45 cm) and higher weight of fruit (677 - 759 g). Hence, chemical fungicide Krilaxyl was found better for the management of downy mildew disease in open field cucumber cultivation. Further, researches on bio-fungicides, especially of native strains are required for best result.

ABSTRACTA study to determine the effect of auxin talcum on rooting of air layered malay apple (Syzygium malaccense (L.) Merr. & Perry) was conducted from March to May 2016. The experiment was arranged in a randomized complete block design with three replications, five branches per experimental unit. Auxin talcum treatment consisting of 7 level of auxin concentrations, i.e., (in ppm) 0 (control), 2000 IBA, 4000 IBA, 2000 NAA, 4000 NAA, 1000 NAA + IBA 1000 and 2000 IBA + 2000 NAA in the form of talcum-paste were applied in the upper region of the girdled branches prior to being covered with soil medium. The results showed that after two months, all treatments containing NAA, either singly or in combination with IBA produced 100% rooting, whereas the control treatment was only 22%. The IBA treatments singly at 2000 and 4000 ppm produced 44.4% and 55.6% rooting, respectively. The superiority of NAA upon IBA treatments was also shown by the higher number and length of primary roots as well as earlier root formation. The best treatment for Malay apple rooting was 4000 ppm NAA which produced 33.3 roots, and formed roots three weeks earlier than the control treatment.Key words: air layering, auxin, IBA, NAA, rootingABSTRAKPenelitian ini bertujuan mempelajari pengaruh formulasi pasta auksin yang mengandung IBA, NAA atau kombinasi keduanya terhadap pengakaran cangkok jambu bol (Syzygium malaccense L.)

A field experiment was conducted at Prime Minister Agriculture Modernization Project (Zone office), Bijuwar, Pyuthan from 18th April, 2017 to 12nd September, 2017 to evaluate the efficacy of Trichoderma viride in the management of leaf blast diseases of rainy season rice under field conditions. The experiment was laid out in two factors factorial Randomized Complete Block Design with five replications. The treatment consisted of two varieties of rice of which one is improved and resistant to blast disease (Sabitri) and another is local (Radha 7) and two rates of Trichoderma viride (5 ml/lit. and 0 ml/lit.). The leaf blast disease was scored three times using the disease rating scale 0-9 given by IRRI, 2002 from 75 DAT to 85 DAT at 5 days interval. The disease incidence, severity and AUDPC value were calculated and analyzed by using RSTAT. The variety factor and Trichoderma viride factor varied significantly for leaf blast incidence, severity and AUDPC, however, the interaction of variety and Trichoderma viride factor varied significantly only in AUDPC value. Disease incidence, severity and AUDPC were found least in Sabitri in comparison to Radha 7. T. viride had significant role in reducing the disease incidence, severity and AUDPC value. The interaction of Sabitri and Trichoderma viride treatment was found best with the mean AUDPC value being the least 3.228. So, the application of Trichoderma viride was found efficient for leaf blast management and it is more effective when applied along with an improved and resistant variety.

Chitosan is a biodegradable natural compound that has a great potentiality in agriculture for controlling plant diseases. An attempt was made to control Fusarium wilt caused by Fusarium oxysporum f. sp. melongenae under inoculated field condition and increase the growth and yield of brinjal by chitosan. Before setting the experiments in the field, preliminary laboratory experiments were carried out to select virulent isolate and effective dose of chitosan against the mycelial growth of the selected pathogen. F. oxysporum f. sp. melongenae isolate F-1 was found to be the most virulent on brinjal in pathogenicity test. Chitosan @ 1.0% concentration was appeared to be the highest inhibitory to the test pathogen at in vitro condition. Additionally, seed treatment with 1.0% chitosan for 12 hrs resulted in the highest increased in germination and seedling growth of brinjal. The field experiment was conducted following Randomized Complete Block Design (RCBD) with four treatments. No treatment was given in T1, the pathogen was inoculated in T2 and seed treatment and soil amendment with 1.0% chitosan was done in T3 and T4, respectively, in test pathogen inoculated condition. Application of 1.0% chitosan as a seed treatment (T3) or soil amendment (T4) significantly reduced pre- and post-emergence seedling mortality, incidence and severity of Fusarium wilt as well as enhanced germination percentage, plant growth and yield of brinjal. On the contrary, pre-emergence and post-emergence seedling mortality, disease incidence and severity of Fusarium wilt were highest in treatment T2 where the soil was inoculated with pathogen without chitosan. Therefore, chitosan could be used against this vascular disease as an alternative to inorganic fungicides and augment yield.
