Prevention and control measures will be implemented immediately before and after September 10th, with prompt treatment of pests within one week. The late-maturing single-season rice in the Huaibei and Jianghuai regions is currently under control, as well as the double-season late rice and single late rice along the Yangtze River. The target for prevention and control is set at 100 or more young nymphs per square meter, with a threshold of over 1,000 nymphs per square meter. For prevention techniques, paddy field blocks should be established to limit pest spread. Early-stage nymphs should be controlled using a mixture of 25% ciprofloxacin at 80 grams per mu and 40% chlorpyrifos at 100 milliliters per mu (or 48% emulsifiable concentrate at 80 milliliters). For middle and older instar nymphs, apply 40% chlorpyrifos at 120 milliliters per mu (or 48% emulsifiable concentrate at 100 milliliters) combined with 15–20 grams of Silk Run. When applying pesticides, ensure sufficient water volume: at least 60 kg per mu for manual sprayers and 30 kg for motorized sprayers. For late-season rice, use no less than 40 kg of water per mu. Motorized sprayers should spray at least 15 kg of solution onto the lower parts of the rice plants, and maintain shallow water levels in the field for 3–5 days after application. In dry or anhydrous fields, apply 80% dichlorvos at 300 milliliters per mu, mixed with 15–20 kilograms of dry sand or soil. This should be done on sunny days between noon and 2:00 PM to maximize effectiveness. Always follow safety guidelines when handling pesticides and ensure proper coverage and timing for optimal results.

Red Light Therapy Panel Photodynamic Panel Red Light Panel Device Red Light Therapy Panel,pdt machine,infrared light therapy device,Red Light Therapy Bed,led light therapy panel Red light therapy, also known as photobiomodulation or low-level light therapy, is a non-invasive treatment that uses red or near-infrared light to stimulate cellular function in the body. The therapy involves exposing the skin to specific wavelengths of light, typically between 600 to 1000 nanometers, which can penetrate the skin to a depth of about 5 millimeters. Red light therapy works by stimulating the mitochondria in the body's cells, which are responsible for producing energy (ATP). The light energy absorbed by the mitochondria triggers a series of biochemical reactions that can enhance cellular metabolism and promote various therapeutic effects.
