One must see the advanced nature of biological pesticides. Biopesticides are one of the earlier scientific and technological achievements in the development and application of bioengineering technology. China's application started in the late 1950s and early 1960s. The content of biological pesticides is many and it includes microbial pesticides, biochemical pesticides, genetically modified organisms, natural enemies, biological pesticides and plant-derived pesticides. The use of biological pesticides, one can kill a variety of pests and diseases; two can produce pollution-free green food; three can reduce the pollution of the environment to ensure the safety of humans and animals; four can protect natural enemies; Fifth, pests and diseases are not easy to produce resistance. According to the statistics of the Ministry of Agriculture, there are 77 varieties of biological pesticides registered in China, accounting for 13.4% of the active ingredients; 691 products, accounting for 71% of registered pesticide products; production of nearly 100,000 tons of pharmaceutical preparations, using area 400 million mu times. Of course, biological pesticides are only one of the organizational components of pesticides, and they cannot substitute for chemical pesticides. Further development is needed to increase the application level.
The second is to understand the mechanism of biological pesticides. Biological pesticides have a gradual process of damage to pests and diseases, such as high-efficiency BT, paralysis of pests first, and then destruction of the internal organs to death, which takes 1 to 3 days. For example, an insect virus is a virus particle nucleic acid that enters the body of the insect and sucks nutrients, resulting in the disintegration of the cell tissue. It takes 3 to 5 days. For example, the effect of Jinggangmycin on the pathogenic bacteria is to hinder the binding of cell wall wall amino acids, so that The mycelial tips produce abnormal branches. Although the visual effects of biological pesticides are slower than those of chemical pesticides, the pests after application have been inhibited or exist in name only. Therefore, it must be rationally applied according to the characteristics of these pesticides.
Third, the correct application of biological pesticides. 1, according to the local plant protection department pest occurrence forecast, increase the number of days to apply biological pesticides; 2, must be strictly in accordance with the dose of medication, can not arbitrarily increase or decrease the concentration; 3, in order to improve control efficiency and safety performance, with some Mix low-toxic pesticides to minimize the harm of high-toxic pesticides, but high-efficiency BT is forbidden to be mixed with fungicides and acidic reconstitution fluids, and can not be applied in mulberry fields; 4. Can not expose the drugs to moisture or dampness; 5. Choose sunny afternoon medications, Or cloudy medication, after the drug encounters rain, must be sprayed again.
Therapeutic heating pads usually operate from household current and must have protection against overheating.
A moist Heating Pad is used dry on the user's skin. These pads register temperatures from 76 to 82 °C (169 to 180 °F) and are intended for deep tissue treatment and can be dangerous if left on unattended. Moist Heating Pads are used mainly by physical therapists but can be found for home use. A moist cloth can be added with a stupe cover to add more moisture to the treatment.
