Second, recent advancements and prevention strategies have been developed to address plant diseases. One of the key approaches involves the use of newly developed control agents in conjunction with base fertilization. During the budding stage of fruit trees, when buds are still not fully expanded, the first application of second-generation viral DNA is sprayed at a dilution of 750 times, with one pound of fresh milk added to the solution. The second application of second-generation viral DNA is administered seven days before flowering (again at 750 times dilution with one pound of fresh milk). For apple trees, the third application is done before bagging, also using 750 times dilution and adding fresh milk. This method effectively prevents and controls blossom blight. Trees affected by Hualian disease can be treated continuously for three years, after which no tree will show symptoms of flower face disease. Once applied, this treatment helps prevent future damage from Hualian disease.
The second-generation viral DNA is a neutral acid-specific viral inhibitor that can be combined with antifreeze, organosilicic compounds, acidic pesticides, foliar fertilizers, sugars, vitamins, amino acids, and vinegar. This compatibility enhances its effectiveness and broadens its application range.
Other preventive measures include managing environmental factors that impact fruit trees. During the germination period, sudden temperature changes due to climate fluctuations can harm the trees and increase susceptibility to viral infections.
To protect against low temperatures below 6°C, it is recommended to mix 500 times diluted antifreeze with 0.3% brown sugar (after slight hydration) and spray the apple trees to prevent cold damage or frost injury to flower buds. When temperatures exceed 23°C during flowering, a mixture of 500 times diluted organic silicon silicate and 0.3% vinegar should be sprayed over the entire tree to prevent heat stress and ensure normal pollen pollination. On days with light rain or fog, spraying 500 times diluted rotten spirit along with Keling-based agents can help prevent apple rot, mold heart disease, and malformed fruits.
During the growth phase, regular applications of foliar fertilizers like organosilicic compounds and seaweed extract, along with trace elements such as silicon and iodine, are beneficial. After the summer solstice, which marks the critical period for next year’s flower bud development, it is essential to apply boron to support flower bud formation. This should be done by spraying the trees twice between June 22 and August 22. Use high-purity boric acid or borax (note: borax is insoluble in cold water below 40°C), prune new shoots sparsely, and allow proper air circulation and sunlight penetration to promote the formation of numerous effective flower buds, laying a solid foundation for a high yield the following year.
When there are many flowers, top-dressing with iodine-containing fertilizers, such as foliar sprays or seaweed-based products, should be done seven days after flowering. Choose stable and effective products to ensure optimal results.
