In July, the occurrence of walnut diseases and pests caused a major threat to the healthy development of the walnut industry. The major pests and diseases of walnuts in summer were introduced as follows.
What are the main pests and diseases
During the period of walnut fruit expansion and even mature, from late May to early July is the physiological fruit drop period, young fruit period should avoid the use of various types of copper preparations; this time is the risk of leaf-eating pests, the period of this pest cycle Sexual outbreaks, if not prevented, will directly affect the yield and fruit quality, while weakening the tree vigor; Walnut fruit pests and diseases are generally very light, but in recent years, damage and affect the fruit of the coffee tree moth, red spider, red-bellied squirrel And walnuts such as extremities moths and other hazards aggravated; walnut Tianniu in some areas, especially the original fruit forest, serious, prevention and control of adult beetle should become another focus; July to August all kinds of walnut leaf spot and other leaf diseases and stem rot The epidemic of diseases and root rots has a great impact on young and middle-aged trees and nursery land; after the beginning of August, the risk of walnut canker disease has a second peak, spreading quickly, and relapses of old lesions that are not completely prevented. Key prevention and control objects: Walnut leaf-feeding pests (mainly including: White-billed Mosquito, Moslaterii, Lepidoptera, Lepidoptera, Spotted Moth, Locust, Leaf A, etc.), Tianniu (mainly include: Sang Tianniu, Xing Tian Niu, Yun Tian Long Tian Niu, Wrinkled Mandarin Orange, etc.), Walnut Blight, Walnut Ulcer, and Red-bellied Squirrel.
Comprehensive prevention and control measures
Ecological control: artificial control. During the period from June to July, the trunk of the forest was observed and freshly carved troughs were found. The wounds and their surroundings were hammered with wood to kill the eggs and newly hatched larvae. From July to August, the hickory leaf pests were manually removed; Young trees pay attention to shade and prevent stem rot. Green manure. From the end of August to the end of September, according to local conditions, the forest will grow green rapeseed, radish, milk vetch, day lily and other local green manure. Disable chemical herbicides: Disable various types of chemical herbicides, use mechanical or manual cutting.
Physical prevention and control: If conditions permit, a frequency-vibration insecticidal lamp can be set up every 15 to 30 mu to trap and kill some parthenophagus, coffee wood moth and most leaf-feeding pests, as well as adult leafhoppers.
Chemical and biological control: Various leaf diseases such as walnut brown spot and erythema disease. In the initial stage of disease, various kinds of copper preparations including 0.3% tetracycline are alternately used to control 2 to 3 times. Hickory leaf-feeding pests, using 0.5% azadirachtin, nitrocarbamide suspoemulsion, nicotinic acid biopesticides during the young instar larvae period, chemical pesticides alibaba, 25% phoxim microcapsules when the insect population is high Agents, 5% A-dimensional saline dispersant spray control; Hickory tapeworm: the use of aphids designed to kill 3% hypertonic phenoxyvir 1000 times liquid control. Hickory red spider: After entering the end of June, it can use 73% of acetylene and 20% of triazoni.

850nm and 660nm waves. These have been proven to: stimulate acupuncture points, increase blood circulation and help with antioxidant enzyme release. Phototherapy in this spectrum also promotes muscle relaxation and generally facilitates pain reduction, stimulates fibroblast and collagen production, increases lymphatic drainage, and reduces swelling, inflammation and bruising- bringing relief to athletes, sufferers of arthritis, and those with chronic pain.
The energy can flow through the body and interact with damaged cells in many parts of the body operating more like a vitamin that goes where it needs to go. This wavelength is also best for treating the lymph system and acupuncture points. Whereas studies show near-infrared wavelengths in the 850 nm penetrate deeper through skin and bone for relief of chronic pain.
As with red light therapy, near infrared light therapy does not mask the symptoms of pain, it encourages the healing of the actual cause of the pain. Once absorbed, the light energy kicks off a whole series of metabolic events, stimulating the body`s natural processes on a cellular level. There is an increase in blood flow, allowing the parts of the body to receive the oxygen and nutrients they need in order to function more effectively. Regeneration is stimulated. Inflammation and pain are reduced.
In many cases, after a course of treatment with red infrared light, the pain is gone.
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.
Some potential benefits of red light therapy include:
1. Skin health: It can improve the production of collagen and elastin, leading to improved skin tone, reduced wrinkles, and acne treatment.
2. Pain relief: It may help reduce inflammation and alleviate pain in conditions such as arthritis, muscle strains, and joint pain.
3. Wound healing: Red light therapy can promote tissue repair and accelerate wound healing by stimulating cell growth and circulation.
4. Hair growth: It has shown potential in stimulating hair growth and treating conditions like androgenetic alopecia (pattern baldness).
5. Mood enhancement: Red light therapy may have positive effects on mood and mental well-being by improving serotonin levels and reducing symptoms of depression and anxiety.
