Cinnamon oil, the most efficacious plant product in vitro, was further tested in the greenhouse for the control of the disease on two rice cultivars inoculated with R. oryzae-sativae. One milliliter of each of four cinnamon oil concentrations (12.5, 37.5, 62.5, or 87.5%) diluted in vegetable oil was applied to the surface of the water in constantly flooded pots.

However, cinnamon oil at 87.5% was phytotoxic. Cinnamon oil has potential to control aggregate sheath spot but relatively high concentrations were required for disease suppression.

Four plant extracts, ginger, pepper, basil, and garlic and four plant essential oils, neem oil, garlic oil,
01-01-2020· Development of plant-based emulsion formulations to control bacterial leaf blight and sheath brown rot of rice. particle aggregation will probably not occur for charged particles. Further research is necessary to explore the efficacy of natural plant products against plant diseases in crop management systems.
PLANT ROOT EFFECTS ON SOIL ERODIBILITY, SPLASH DETACHMENT, SOIL STRENGTH, AND AGGREGATE STABILITY F.Ghidey, E. E. Alberts ABSTRACT. The influence of dead roots on soil erodibility,splash detachment, and aggregate stability was studied in the laboratory using a rainfall simulator on a Mexico silt loam (fine, montmorillnitic, mesic, Udollic
Efficacy of plant extracts on the toxicity, to the usage of natural products that include plant extracts, control pests with varying level of effectiveness [13]. Insect damage in stored grains and pulses may amount to 40% in countries where modern storage technologies have not been introduced.
Microbial inoculants can be considered as safe, low cost and comfortable additives that represent a nature-based option for plant growth promotion and disease control [20, 1].
Plant growth experiments often require the use of various growth media substrates to control for water retaining potential, nutrient availability, and anchoring of roots in the media. Murashige and Skoog (MS) agar-based media was developed for tobacco as a suitable substrate that allows rapid growth and shows minimal side effects on bioassays and chemical treatments in tissue culture [19] .
Natural Products with Phytotoxic and Plant Growth Regulatory Activity: showing excellent efficacy against the organophosphorus- and carbamate-resistant strains as well as the susceptible strains of green rice leafhoppers and planthoppers. This antibiotic is widely used for the control of sheath
4. Antimicrobial Assays. Assays that have been used to test the antimicrobial properties of medicinal plant extracts and natural products used to treat or prevent oral diseases involve assessing the capacity of the test material to inhibit the growth of typical oral pathogens, such as Streptococcus sp. (as an example of bacteria implicated in dental caries) and P. gingivalis (as an example of
In many situations, foliar fungicide applications may be economically justified for reducing losses from sheath blight if 1) disease pressure is sufficiently high; 2) susceptible rice varieties are grown; 3) the crop has a high yield potential in the absence of sheath blight; and 4) environmental conditions are favorable for the disease to spread to the upper parts of the rice plant.
Chitosan effectively inhibits radial mycelium growth, sporulation, spore germination and elongation of Fusarium spp., 32-34, Rhizopus spp., 35,36, Phytophthora spp., 37,38, Botrytis spp., 39,40 and Alternaria spp., 41 etc. Meng et al. 42 demonstrated the inhibition rate of mycelium growth of fungi depend on the concentration of chitosan and its derivatives, oligochitosan.

25-02-2019· 1. Introduction. Tea (Camellia sinensis) is the most consumed beverage in the world, aside from water, and is widely believed to have positive effects on human health [].The Chinese have known about the medicinal benefits of green tea since around 2,737 B.C. [].One important aspect of green tea is the fact that it is rich in polyphenols.
Sambucus nigra L. products - Sambucol - are based on a standardized black elderberry extract. They are natural remedies with antiviral properties, especially against different strains of influenza virus. Sambucol was shown to be effective in vitro against 10 strains of influenza virus. In a double-b
