First, control adult worms. During the initial stage of adult emergence, apply 50% dichlorvos EC diluted at 1000 times, or 80% dichlorvos EC at 1500 times, or 90% trichlorfon diluted at 1000 times. Spray 30-40 kg per mu to effectively manage the adult population. This step is crucial in preventing them from laying eggs and causing further infestations.
Second, control larvae. It's recommended to irrigate with a root solution. Use 80% dichlorvos emulsifiable concentrate or 90% trichlorfon diluted between 800 to 1000 times, mixing 150-200 milliliters into each batch of irrigation water. Ensure the liquid flows from the cabbage leaves down to the rhizosphere. This not only helps prevent earthworms but also controls pests like locusts, cabbage caterpillars, and diamondback moths. Additionally, you can mix fine sand or fine furnace ash with 2.5% trichlorfon at a rate of 0.5 kg per 15-20 kg of mixture. Apply this around the roots of radish and cabbage before drosophila spawn to prevent infestation effectively.
Third, implement fall annihilation. After harvesting radishes and cabbages, plow the fields deeply to destroy overwintering pupae. This practice significantly reduces the insect population for the next season, minimizing damage and improving crop health. By taking these steps throughout the growing cycle, farmers can maintain a healthier environment and ensure better yields.
Wound Protector/Retractors
Custom size medical incision protectors are medical devices specially designed to protect surgical incisions from external contaminants and mechanical damage. They are designed to fit snugly over the incision area and provide a barrier against bacteria, fluids, and other harmful substances that could lead to infection.
To create custom-sized medical incision protectors, medical professionals use advanced 3D scanning and printing technology to create an exact mold of the patient's incision area. This mold is then used to create a custom incision protector that perfectly fits the patient's unique anatomy.
These devices are usually made of medical-grade silicone or other biocompatible materials that are safe for use in the human body. They are easy to apply and remove, and can be reused many times.
Custom sized medical incision protectors are commonly used in a variety of surgical procedures, including orthopedic, cardiac, and plastic surgery. They are an important tool in preventing postoperative infection and ensuring optimal healing outcomes for patients.
