Every kind of fruit tree is different, even big trees and small trees are different. The control targets are different in different regions.
The main common pathogens of apple trees are: leaf fall disease (including: spotted leaves, brown spots, round spots, etc.), fruit hazards such as anthracnose, mildew, etc.
70%-80% of the time when the flowers fall is a critical period for the prevention and control of anthracnose, mildew and other diseases. The main medications are: Benmidiconazole, Mancozeb, Prosenzine, Carbendazim, Thiophanate-methyl, etc.;
The first time to prevent and control falling leaves was in June, when the weather gradually turned hot, and the germs and diseases began to harm fruit trees. Bordeaux mixture can be used to prevent this during this period. Every 20 days thereafter, mancozeb, tebuconazole, and carbendazim are used alternately. Also prevent Starscream!
The weather in each place, the planting structure is different, and the management plan is also different. We can discuss the specific situation together!
The garden is cleared in spring, usually half a month before budding, once the flower dew period is red, and 80% of the declining flowers start to spray, 3 times in a row, with an interval of about 7-10 days, and then start bagging. Emulsifiable concentrates are generally not used for medication before bagging, and powders are generally not used. They are all relatively high-grade fungicides. The management after bagging is more extensive, and varies greatly depending on the region.
Apples are generally administered 10-12 times a year. According to the situation, 11 times are normal. They are: dry branches (dormant period) in mid-to-late March, flower dew red period (mid-April) for three times of bagging. Early May-early June, about 20 days after declining flowers in mid-May, about 30 days after declining flowers, 2-3 days before bagging), usually 5-6 times after bagging, after unpacking*** ***Play the fungicide again.

The RT-PCR Test Reagent Kit is a real-time, RT-PCR test intended for the qualitative detection of nucleic acid from SARS-CoV-2 in oropharyngeal and nasopharyngeal swab specimens from individuals suspected of COVID-19 by their healthcare provider. This test is also for use with anterior nasal swab specimens that are collected using the COVID-19 Test Collection Kit when used consistent with its authorization.
Results are for the identification of SARS-CoV-2 RNA. The SARS-CoV-2 RNA is generally detectable in the upper respiratory specimens during the acute phase of infection.
Positive results are indicative of the presence of SARS-CoV-2 RNA; clinical correlation with patient history and other diagnostic information is necessary to determine patient infection status.
Positive results do not rule out bacterial infection or co-infection with other viruses. The agent detected may not be the definite cause of disease.
Negative results do not preclude SARS-CoV-2 infection and should not be used as the sole basis for patient management decisions. Negative results must be combined with clinical observations,patient history,and epidemiological information.
