High temperature weather, kiwifruit diseases and pests should be integrated prevention and treatment
In the summer, the weather is mainly high temperature and high humidity. In this environment, diseases such as root rot, root knot nematode disease, leaf mold, fruit spot and black spot disease, and yellowing disease are prone to occur in fields of kiwifruit. Insect pests such as shell beetles, beetles, large gray elephant weevil, and leafhoppers, farmers' friends must follow the principle of “mainly prevention, comprehensive prevention and control,†and actively implement the prevention and control of kiwifruit diseases and insect pests in summer. Strengthen management, reasonable fertilizer implementation of Orchard standard management practices, set production and fertilizer, reasonable load, ensure robust growth of trees, improve resistance. To avoid large water, excessive load, easy to cause root damage, weakening tree vigor, provide favorable conditions for pests and diseases. Rationally regulate tree growth, balance tree vigor, and improve stress tolerance. For yellowing trees and small old trees, it can be used to regulate and control bicuspids, alizarins, mesobiocins, etc. to promote growth and strong vigor. It can be used for vegetative overgrowth. Use PBO to control and prosper, improve the balance of physiological metabolism of the tree, regulate the tree potential through science, and increase the resistance to pests and diseases. Chemical control of brown spot disease, low pay A treatment in early July: in the event of damage can be used 60% Baitai water dispersible granules 1000 times +48% chlorpyrifos EC 1500 times; or Cui Miao 3000 times +10% cypermethrin microemulsion 2000 times; Or 10% difenoconazole wettable powder 1500 times + 4.5% beta-cypermethrin spray control 1500 times. Precautions Avoid the use of drugs during the high temperature period. Before 11:00 am and after 4:00 pm, avoid injury. Cautious use of foliar spray, the use of regular foliar spray fertilizer, regulators, the use of standard dosage, improper selection or use is prone to injury. It is forbidden to use the remaining medicaments that were opened every other year in order to prevent deterioration of the products and produce phytotoxicity to young leaves and young fruit. Before and after the use of drugs to clean up the spraying equipment, herbicides and equipment must be dedicated to the safety of the operator at the same time.

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.
