Some farmers' friends use pesticides and they often have headaches and headaches. Tomatoes had a late blight on Pulpico or metalaxyl, and when the early blight occurred, they sprayed mancozeb or antivirus, and a bacterial disease occurred. The result was a disease that was cured by a copper spray. In the case of a disease, the scoop on the gourd went up again. No cure was found. The reason is that the single medication is not conducive to the comprehensive control of various diseases. The use of scientific and rational mixtures of pesticides can expand the scope of use or treatment of several harmful organisms, and can even increase the efficacy and reduce the side effects of pesticides, pesticides, pesticides, etc., which is both efficient and time-saving. For example, copper can be mixed with many fungicides and insecticides. Mix and spray with 30% suspension 600 times liquid and 70% thiophanate-methyl 800 times to control bacterial leaf blight, anthracnose, and bacterial keratopathies in vegetables, and with kasugamycin Garryon was used as a mixture to control bacterial and fungal diseases in tomato.
The kit is used for in vitro qualitative detecting the ORF1ab/N genes of novel coronavirus 2019-nCoV and Delta Variant in respiratory specimens including oropharyngeal swabs, nasopharyngeal swab, sputum and bronchoalveolar lavage fluid, and performing D950N mutation detection of Delta variant of Novel Coronavirus 2019-nCoV.
As reported in GISAID database, more than 95% Delta variant of Novel Coronavirus 2019-nCoV carry D950N mutation.
