Aims: To evaluate the nematicidal potential of wild spinach powder in combination with fresh chopped leaves of different plants viz., Indian mallow, Mexican poppy, Ivy gourd, Trailing eclipta, Wild eggplant and Black pigweed against Meloidogyne incognita on plant growth characters of tomato cv. K-21. Place and Duration of Study: A glasshouse pot experiment was carried out in the Department of B...

medicinal plant powders have traditionally been used as grain protectants against stored-product insect pests. in this study, insecticidal activity of carum copticum l. and cuminum cyminum l. powders was assessed on adults of sitophilus granarius l. and tribolium confusum jacquelin du val. experiments were carried out on wheat at 27 ± 1 ºcand 55 ± 5% r. h. the mortality increased with increasin...

The antifungal effect of twenty powdered spice plants and their extracts at concentrations of 2, 4, 8 and 1, 3, 6%, respectively was evaluated in relation to the radial mycelial growth of various soilborne fungi causing damping-off disease. The spice powder or extract were added to the culture medium PDA to obtain the proposed concentrations. Concentration of 8% of powdered spices and 6% of the...

The effects of five nanomaterials (multiwalled carbon nanotubes [MWCNTs], Ag, Cu, ZnO, Si) and their corresponding bulk counterparts on seed germination, root elongation, and biomass of Cucurbita pepo (zucchini) were investigated. The plants were grown in hydroponic solutions amended with nanoparticles or bulk material suspensions at 1000 mg/L. Seed germination was unaffected by any of the trea...

Direct detection of saponins in medicinal plants using Fourier Transform Infrared (FTIR) spectroscopy is reported in this paper. Crude dry plant powders were mixed with potassium bromide (KBr) powder and compressed to a thin pellet for infrared examination. FTIR spectra of the test samples showed -OH, -C=O, C-H, and C=C absorptions characteristic of oleanane triterpenoid saponins. The C-O-C abs...

Some bacteria can produce extracellular bacterial cellulose (BC). This polysaccharide is chemically identical to cellulose produced by plants but has no associated lignin and hemicelluloses. The unique mechanical properties, chemical stability and purity allow BC to be exploited for a range of biomedical applications. However, medium costs limit commercial BC production. The suitability of usin...

In this study two commonly used steels in boiler plants, i.e. (SAE-213) T-22 and SA516 (Grade-70) were coated with different thermal spray processes namely HVOF and cold spray. The coating powder used was made up of NiCrTiCRe powder. The performance of the coated as well as uncoated material was investigated using a pin-on-disc machine [Model: Wear and Friction Monitor Tester TR-20], supplied b...

Studies were undertaken to determine the comparative efficacy of native biocontrol agents viz., Pseudomonas fluorescens isolate PS-4, Trichoderma harzianum isolate TH-H-3 and T. virens isolate TV-K-3 @ 5X10 cfu/g talc; organic amendments viz., neem seed powder @ 250 mg/kg soil and farmyard manure @ 8 1500 mg/kg soil; carbofuran @ 33.4 mg/kg soil, topsin-M @ 1.4 mg/kg soil and bavistin @ 2.0 mg/...

Objectives: The main objective of this study is to cultivate Trichoderma harizanum using agricultural waste as a substrate for the management of damping of disease and growth promotion in Chilli plants. Methods: T. harizanum was isolated from MCRC Main Agricultural Research Station, Chennai, and identified through microscopic observation by using standard keys. F. oxysporum, R. solani, and A.al...

This experiment was carried out to determine the effects of turmeric, cinnamon, ginger and garlic powder on mixed sex Cobb-500 broilers performance, serum antioxidant status, and serum thyroid hormones. Heat stresses were created by increasing ambient temperature to 32-34 ˚C from 12: a.m. to 16: p.m. during days 31-42 of the experiment. Blood serum samples were obtained from 6 broilers of each ...
