2. Objectives
To found a process for manufacturing copper (I) oxide/copper nanomaterials using nano-sized green chemistry method to kill fungal bacteria on orange trees in Ham Yen - Tuyen Quang
3. Creativity and innovation
The project uses an environmentally friendly green chemistry method to produce copper (I) oxide/copper nanomaterials with high antibacterial and antifungal properties for emergency antifungal applications on orange trees in particular and other agricultural crops. Generally speaking. The project uses a green electrochemical method with a simple, easy-to-implement production process with high applicability and lower price than some similar products and good quality. The research results of the project have opened up an application direction for mass production of metal nano products to replace toxic chemical pesticides in Vietnam.
4. Research results
The research has shown some of the following main research results:
- Successfully fabricated copper(I) oxide/copper nanomaterials by green electrochemical method with a combination of anodic dissolution and controlled redox reaction between NaOH and glucose in solution. These materials exhibited distinct morphologies by varying the glucose concentration with a fixed amount of NaOH (i.e., 0.15 M). At low glucose concentrations (i.e., 0.05 and 0.1 M), the material appeared as particle clusters with Cu and CuO phases. When the glucose concentration increased to 0.15 and 0.2 M, cubic material was obtained. When further increasing the amount of glucose to 0.25 M, a flower-like structure was formed. Accordingly, synthesized materials with different sizes and shapes all have different antibacterial properties.
- Results of testing copper(I) oxide/copper nanomaterials with fungal strains in the laboratory showed that copper nanomaterials produced at low glucose concentrations (0.05 and 0.1 M) were effective. The best antifungal fruit.
- Results of testing the concentration of nano copper (I) oxide/copper on a small field scale show that supplementing nano copper (I) oxide/copper to orange trees by foliar spraying shows that supplementing nano copper (I) ) oxide/copper by foliar spray for obvious effect. Copper (I) oxide/copper nano spraying has a positive impact on the growth and development of orange trees, thereby increasing productivity, quality and resistance to some important pests and diseases on orange trees. zone. In the ecological conditions of Ham Yen, Tuyen Quang, on an 8-year- old Sanh orange tree, spraying nano copper (I) oxide/copper at a concentration of 30 ppm is considered the most suitable, the tree has the highest yield (97.28 kg). /tree/crop) and the best fruit quality. Research results also show that nano copper (I) oxide/copper is as effective as the Super Copper Silver product in both preventing harmful bacterial and fungal diseases of orange trees as well as increasing the yield of orange trees. Orange trees in the ecological conditions of Ham Yen district - Tuyen Quang.
