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 approximately 30-40 kg per mu. This method effectively targets adult pests and prevents them from laying eggs.
Next, manage larvae. It is recommended to use root irrigation with a solution containing 80% dichlorvos emulsifiable concentrate or 90% trichlorfon diluted between 800 to 1000 times. Add 150-200 ml of the solution per bucket of irrigation water. Ensure the liquid flows from the cabbage leaves down to the rhizosphere, which not only helps prevent earthworms but also controls other pests like locusts, cabbage caterpillars, and diamondback moths. Additionally, mix fine sand or fine furnace ash with 2.5% trichlorfon at a ratio of 15-20 kg of material per 0.5 kg of trichlorfon. Apply this mixture around the roots of radish and cabbage before the drosophila lay eggs, which can effectively prevent infestation.
Finally, implement fall eradication. After harvesting radishes and cabbages, plow the fields deeply to destroy overwintering pupae. This practice significantly reduces the pest population for the following year, minimizing damage and improving crop health. By following these steps, farmers can maintain better pest control throughout the growing season and ensure more productive harvests.
Radial Artery Compression Devices
Radial artery compression devices, also known as radial artery compression devices or wristbands, are used to achieve hemostasis after a transradial cardiac catheterization procedure. The device is applied to the wrist and inflated to compress the radial artery, which is the artery that supplies blood to the hand and fingers. This compression helps to prevent bleeding and hematoma formation at the site of the catheterization.
Radial artery compression devices are preferred over traditional compression methods such as manual compression because they are more effective, comfortable for the patient, and allow for earlier ambulation and discharge. They also reduce the risk of complications such as radial artery occlusion and nerve injury.
In addition to cardiac catheterization procedures, radial artery compression devices may also be used after other procedures that involve the radial artery, such as transradial access for arterial blood gas analysis or for the placement of intra-arterial lines.
