In winter, temperatures are low, and most of the activities and hazards of crop pests and diseases are hidden and stationary. In the prevention and control of crop diseases and insect pests, special attention should be paid to the following points: 1. In the winter, crop pests and diseases should be controlled, and pesticides less affected by temperature should be used. 2. Choose sunny day high temperature medication. Because in the winter when the temperature is high, the pest's range of activity and respiratory intensity increase, the amount of food intake increases, the liquid is sprayed on the body of the body, and more medicines are brought into the body, which is conducive to exerting a toxic effect. 3. Appropriately increase the dose. The lethal dose of pesticides from pests is not constant. The lower the temperature at room temperature, the lower the lethal dose of insect pests. Therefore, increasing the dose of pesticides in winter can prevent insecticides from eating and killing. However, it must not exceed the "high concentration of safety" (ie, the maximum allowable dose of phytotoxicity). When applying pesticides in winter, water should be added strictly according to the dilution factor. Do not arbitrarily increase or decrease the amount of water. 4. Improve the application method. In winter, greenhouse pests and diseases should be treated with smoke or dust as much as possible; if spray application is used, the number of control and spray volume should be appropriately reduced to prevent excessive humidity in the greenhouse. 5. Properly extend the safety interval. The degradation rate of pesticides in winter will be slower, and pesticides will remain in the crops for a relatively long period of time. When pests and diseases of vegetable crops are controlled, the number of days from the last application of crops to harvesting (ie, safety intervals) must be appropriately extended to ensure food safety.
Antiviral & Anti-cancer
Antiviral:
Antiviral drugs
are a class of medication used specifically for treating viral infections. Like
antibiotics and broad-spectrum antibiotics for bacteria, most antivirals are
used for specific viral infections, while a broad-spectrum antiviral is
effective against a wide range of viruses. Unlike most antibiotics, antiviral
drugs do not destroy their target pathogen; instead they inhibit their
development.
Antiviral drugs
are one class of antimicrobials, a larger group which also includes antibiotic
(also termed antibacterial), antifungal and antiparasitic drugs, or antiviral
drugs based on monoclonal antibodies. Most antivirals are considered relatively
harmless to the host, and therefore can be used to treat infections. They
should be distinguished from viricides, which are not medication but deactivate
or destroy virus particles, either inside or outside the body. Antivirals also
can be found in essential oils of some herbs, such as eucalyptus oil and its
constituents.Related Products:antiviral drugs,anti-cancer drugs.
Anti-cancer:
Anticancer, or
Antineoplastic, drugs are used to treat malignancies, or cancerous growths.
Drug therapy may be used alone, or in combination with other treatments such as
surgery or radiation therapy.
