How does natural biopesticide affect the production of onion?4 answersNatural biopesticides, derived from plants, microorganisms, and insects, have shown efficacy in controlling pests like fungi and bacteria in onion production. Studies have highlighted the effectiveness of bio-agents like Trichoderma harzianum, T. viride, Bacillus subtilis, and Pseudomonas fluorescens in managing onion basal rot caused by Fusarium oxysporum f. sp. cepae. These bio-agents have demonstrated significant growth inhibition of the fungal pathogen, with T. viride and T. harzianum inducing the highest inhibition rates. Additionally, biopesticides have been found to reduce disease incidence in onions under field conditions, with P. fluorescens and T. viride showing the highest disease reduction percentages, followed by B. subtilis and T. harzianum, as compared to chemical fungicides like Carbendazim. The use of natural biopesticides not only effectively manages onion diseases but also promotes soil fertility, offering a sustainable alternative to chemical pesticides in onion production.
Is garlic effective in preventing termites?4 answersGarlic has been found to be effective in preventing termites. Studies have shown that garlic extracts have a contact killing effect on termites, causing mortality rates of up to 100%. The effectiveness of garlic in termite control is attributed to its high concentration of active compounds, which have been found to be toxic to termites. Additionally, the use of garlic in combination with other plant extracts, such as cinnamon and fructus cnidii, has been shown to enhance its termite control properties. The use of garlic as a termite control method is considered safe for humans and livestock, and it is also environmentally friendly. Overall, garlic shows promise as an effective and sustainable alternative for termite prevention and control.
What is significance of the study of garlic as pesticide?4 answersThe study of garlic as a pesticide is significant due to its potential as an alternative to conventional pesticides for crop protection. Garlic contains biologically active defense compounds, such as allinase, which can prevent and treat diseases in plants and animals. These compounds have insecticidal, fungicidal, bactericidal, and nematicidal properties, making garlic products effective against a wide range of pests and pathogens. Using garlic as a pesticide can reduce non-target exposure to hazardous chemicals and help curb resistance development in pests, promoting sustainable organic crop protection. Additionally, the use of garlic extracts in pesticide formulations has shown promising results in controlling pests like grubs, mole crickets, cutworms, and wireworms, leading to increased crop yields and improved product quality. Overall, studying garlic as a pesticide offers a natural and environmentally friendly approach to pest management in agriculture.
Is garlic (Allium sativum) a good disinfectant spray for use against bacteria, viruses, and fungi?5 answersGarlic (Allium sativum) exhibits antimicrobial properties against bacteria, viruses, and fungi. It has been shown to inhibit the progression of Escherichia coli, Salmonella typhi, Staphylococcus aureus, Aspergillus parasiticus, and Aspergillus flavus. Garlic extracts have also been found to have antibacterial activity against Vibrio parahaemolyticus. The organosulfur compounds in garlic, such as allicin, ajoenes, and allyl sulfides, have been shown to have bactericidal and antibiofilm properties. These compounds form disulfide bonds with enzymes and compromise the integrity of bacterial membranes. While garlic shows promise as an immunostimulant in aquaculture and as an antimicrobial agent, further research is needed to determine optimal dosages, interactions with environmental factors, and its effects on immune responses. Additionally, the emerging role of new technologies in harnessing the potential of garlic as a novel antibacterial agent is being explored.
What are the potential uses of garlic based solutions?3 answersGarlic has potential uses in various health conditions, including cancer, cardiovascular and metabolic disorders, blood pressure, diabetes, Alzheimer's disease, and chronic kidney disease. It has been shown to have antioxidant, anti-inflammatory, and lipid-lowering properties, which contribute to its health-promoting effects. Garlic extracts, especially aged garlic extracts (AGEs), are rich in bioactive compounds that have anti-inflammatory, antioxidant, and neuroprotective activities, making them beneficial for improving learning and memory. The therapeutic potential of garlic is influenced by its preparation and extraction methods, with aged garlic extract (AGE) being particularly effective due to the conversion of odorous compounds into stable and safe compounds with enhanced therapeutic effects. Additionally, garlic has antimicrobial effects and can reduce the risk of cardiovascular disease and cancer. In the context of chronic kidney disease, garlic may have potential benefits in mitigating associated cardiovascular complications and gut dysbiosis.
How is yeast used as a biopesticide for pechay?5 answersYeast can be used as a biopesticide for controlling postharvest diseases in crops such as blackberry and citrus. The yeast strains Rhodotorula mucilaginosa Lv316 and rhodosporidium paludigenum Fell and Tallman have been found to be effective in controlling grey mould and other diseases in blackberry crops. These yeast strains have been formulated into biopesticides that can replace chemical fungicides for disease control. In the case of citrus postharvest diseases, a chemical bactericide containing bio-control yeast has been developed. This bactericide, which includes the yeast strain rhodosporidium paludigenum Fell and Tallman, has been shown to effectively control citrus postharvest diseases while reducing the amount of chemical bactericide needed. Overall, yeast-based biopesticides offer a potential green alternative to chemical pesticides for disease control in crops like blackberry and citrus.
