Crop cultivation is inseparable from pesticides and fertilizers, because crop growth is prone to diseases and insect pests. If you do not master the skills, it will cause harm to Hefei, especially insecticides. The following small series will tell you about the pesticides and symptoms that are prone to phytotoxicity. I hope to be helpful.
1, dichlorvos
Stones (with kernels inside, fleshy outside, such as peach, plum, cherry) and kiwifruit are highly susceptible to phytotoxicity, causing a large number of fallen leaves and falling fruits. Do not use them.
Corn is extremely susceptible to phytotoxicity. Beans and melons are very sensitive at seedling stage, causing burning seedlings and should not be used.
The use of high temperature weather before rice heading causes the leaves to become yellow and white, and be used with caution.
Remarks: Dichlorvos has contact, stomach poison and fumigation. It has strong knockdown and rapid efficacy, but has a short-lasting effect, is odorous and volatile, and the higher the temperature, the faster the volatilization. It is difficult to prevent pests and cockroaches, cockroaches and horses mixed with dichlorvos 1000 times, the effect is very obvious. 800 times of root-rooting tigers and yellow-striped worms, the effect is better. The vegetable safety interval is 5 days and the tea is 6 days.
2, chlorpyrifos
Melon (special watermelon), lettuce use at the seedling stage, 100% phytotoxicity. After the melon is 1 meter long, it should be used with caution. When it hits the high temperature, it will burn leaves and medicine spots. The tobacco is very sensitive at any time. The Chinese herbal medicine Sanyeqing is sensitive at any time, causing all fallen leaves. Sensitive to grapes, use with caution.
3, triazophos
Sugar cane, corn, and white cockroaches are easy to produce phytotoxicity and should not be used.
4, malathion
Tomato seedlings, melons, beans, cherries, grapes, and pear trees are all sensitive, and the concentration is used with caution.
The herbicide 2 methyl 4 chloride and malathion use time is short (10 days) and is highly susceptible to phytotoxicity.
5, profenofos
When the concentration is high, it has phytotoxicity to melons and beans; the flowering period of cruciferous vegetables is easy to produce phytotoxicity. It is not suitable for application in the orchard, which is easy to cause aging of the leaves, a large number of falling flowers and fruit, inferior fruits and other hidden phytotoxicity.
6, trichlorfon
It is particularly sensitive to corn and beans, and is susceptible to phytotoxicity. Peach trees are banned. When the concentration is high, the application of high temperature weather also has yellowing phytotoxicity on the tip of rice.
7. Acetylene/Keite, the concentration is too high, it is easy to produce phytotoxicity to the young shoots of citrus, the concentration is best not to be less than 2000 times, especially in honey pomelo.
The Klitsch pear tree is very sensitive and banned. The excessive use of the fruit produces a yellow strip or irregular ring pattern on the citrus fruit, and the high temperature uses the fruit to easily plague the fruit drug spots, affecting the greening.
8, triazolyl, in the case of low temperature, easy to phytotoxicity of spring shoots, severely caused a large number of falling flowers, fallen leaves, fruit drop. When the temperature is below 20 °C, the citrus fruit is used in the young fruit stage, causing the leaves and young fruit to be deformed.
9. Organophosphorus main emulsion formula, such as (chlorpyrifos, marathon, oxidized fruit), etc., used in high temperature and dry season with temperature over 30 °C, wrinkles and deformed medicinal herbs on young leaves, streaky spots on fruits harm.
10, the oil in the summer high temperature, the high concentration of citrus and other fruit trees are highly susceptible to phytotoxicity.
Do not mix with sulfur-containing chemicals (chlorocyanil, captan), copper preparations (bordeaux), ketone, etc.
11. (thiazinone)
It is very sensitive to cabbage and radish, and it immediately appears on the leaves and brown spots and leaf whitening.
12, insecticidal double cabbage, cabbage, and other cruciferous vegetables seedlings and citrus are prone to phytotoxicity,
High temperature in summer on citrus will cause yellowing of leaves and fruits
13, fluridazine (Taibao) flurin
Sensitive to the seedling stage of Chinese cabbage, easy to cause burning of new leaves
Ling fluoro urea / diafenthiuron, high humidity, high temperature above 30 ℃ high concentrations (higher than recommended times), touch light irradiation, easy to produce phytotoxicity on crop seedling.
14. Imidacloprid is sensitive in the seedling stage of melons and beans. The use of melons in high temperature and high humidity greenhouse conditions has the risk of burning new leaves. Use with caution.
Everyone knows that if you want crops to grow well, then disease control is inevitable, but you should not use pesticides as much as you can, because excessive use can cause serious phytotoxicity. These are the most toxic drugs that can be plagued by small series. Let's take a quick look.
What's red light therapy? Red light therapy before and after
Red light therapy (RLT) is a treatment that may aid in the healing of skin, muscle tissue, and other body components. It exposes you to red or near-infrared light at modest intensities. Infrared light is a sort of energy that your eyes cannot see but which your body perceives as heat. Red light is comparable to infrared light, however it is visible.
Low-level laser treatment (LLLT), low-power laser therapy (LPLT), and photobiomodulation are all terms for red light therapy (PBM).
What Is Red Light Therapy and How Does It Work?
Red light treatment involves exposing your skin to a red-light bulb, gadget, or laser. Mitochondria, also known as the "power generators" of your cells, absorb it and use it to produce additional energy. This, according to some scientists, helps cells repair themselves and grow healthier. This promotes skin and muscular tissue repair.
The skin is not injured or burned by red light treatment since it employs very low amounts of heat. It is not the same sort of light used in tanning salons, and it does not expose your skin to UV rays that are harmful to your skin.
What Is It Used For?
Red light treatment has been studied for a long time. However, there aren't many research on it, and no one knows if it's better than other sorts of healing treatments. The use of red light therapy may be beneficial in the following situations:
Dementia. People with dementia who received near-infrared light treatment on their heads and via their nostrils on a daily basis for 12 weeks had improved memory, slept better, and were less irritable.
Pain in the teeth. People with temporomandibular dysfunction syndrome (TMD) experienced decreased discomfort, clicking, and jaw soreness after receiving red light treatment, according to another small study.
Hair loss is a common occurrence. In one research, men and women with androgenetic alopecia (a hereditary condition that causes hair loss) gained thicker hair after using an at-home RLT device for 24 weeks. The outcomes were not the same for those who utilized a bogus RLT gadget in the trial.
Osteoarthritis. According to one research, red and infrared light treatment reduced osteoarthritis-related pain by more than half.
Tendinitis. RLT appears to reduce inflammation and discomfort in persons with Achilles tendonitis, according to a small trial of seven participants.
Wrinkles and other symptoms of aging and damage to the skin. RLT has been shown in studies to aid with wrinkles and skin smoothing. RLT can also assist with acne scars, burns, and sun damage indications.
What Are the Consequences?
Even though experts aren't clear how or why red light treatment works, it's usually thought to be safe. There are also no hard and fast guidelines on how much light to use. Too much light can harm skin tissue, while too little can make it less effective.
What Is Red Light Therapy and Where Can You Get It?
At most cases, it's done in a doctor's office. Some salons and dentistry clinics, however, do it as well. You may also purchase a red light treatment gadget on your own. Side effects and injuries are more likely to occur with salon and at-home treatments. If you're considering red light treatment, see your doctor first.
