The key period of control of black grape pox in red grape

Blackpox, also known as black rot, is a significant disease affecting red grape crops. From the author's understanding, in some fruit-growing regions in recent years, many new farmers have underestimated the severity of this disease due to a lack of awareness about its harmful effects. As a result, there has been insufficient attention given to its symptoms, occurrence patterns, and critical periods for prevention and control. The damage caused by this disease can be quite severe, with general losses ranging from 15% to over 30% in more serious cases. The symptoms of black rot typically affect young leaves, shoots, flower clusters, and developing fruits. The most notable signs include: early appearance of small, red-brown spots on young leaves, often surrounded by a yellow halo; as the lesions grow, they become round or irregular in shape, with a slight depression in the center that turns gray, while the edges take on a dark brown color and appear in lines along the leaf veins. This can cause the leaves to twist, shrink, and eventually dry out, forming dark brown, elliptical or strip-like lesions. On young fruits, the disease starts as a small brown dot, which expands to 2-5 mm in diameter, with a grayish center and a dark brown outer ring, creating a "bird’s eye" appearance. Infected fruits remain small, dark green, hard, and often deformed, with cracked surfaces, making them unsuitable for market. In terms of disease incidence, in Shaanxi Province and northern Guizhou, the pattern follows a seasonal cycle. The disease begins to appear in mid-April, with an increase in May. From early June to July, when temperatures rise and rainfall increases, the disease becomes more prevalent. By mid-July to mid-August, as the weather dries up, the infection rate gradually declines. However, from late August through October, especially during rainy periods, the disease tends to re-emerge significantly. For effective prevention and control, several key periods should be considered: 1. During the spring growth phase, before the leaves fully emerge, it's important to prune and remove diseased stems, scrape off old bark, and burn the infected material. Before bud break, applying a 3-5 degree Bordeaux mixture or spraying 50% carbendazim wettable powder at 800 times dilution can help reduce the initial disease load. 2. During shoot growth and flowering, it's crucial to prevent secondary infections. Spraying 70% mancozeb wettable powder at 600 times or 78% chlorothalonil wettable powder at 1000 times, every 10–15 days for 2–3 applications, can protect the foliage and flowers, promoting healthy development. 3. During the young fruit expansion period, from mid-June to mid-July, the fruits are most vulnerable. Applying 43% pyraclostrobin suspension at 3000–4000 times dilution or using a 1:0.7:240 Bordeaux mixture 1–2 times can improve both yield and quality. 4. In late summer to early fall, from late August to September, when rains are frequent, it's advisable to spray 50% thiophanate-methyl wettable powder at 800 times or DuPont Fuxing at 8000–10000 times. Additionally, proper pruning before winter should be done to remove any diseased leaves, shoots, and fruits, reducing the risk of future outbreaks.

Pet Quantum Analyzer

What is the pet scanner?

[Pet Scanner] involves high-tech innovation projects of medicine, bio-informatics, electrical engineering and other sciences. Using the quantum medicine as the theoretical basis, it applies the advanced electronic equipment to collect the weak magnetic field of animal cells for scientific analysis, thereby analyzing and determining the tested animal's health status and main problems and

putting forward standard prevention recommendations. [Pet scanner] is individualized guide of health care consultation for full animal body and forward health science, and has the advantages of completeness, non-invasiveness, practicality, simplicity, fastness, economy, easy popularization, etc. With the depth and development of scientific research, it will make a greater contribution for the cause of animal health, having a broad development and application prospect.

Principle of quantum analyzer:

The animal body is the aggregates of a large number of cells which are in continuous growth, development, differentiation, regeneration and apoptosis, and the cells constantly self-renew through its own division. In the process of cell division and growth, those charged bodies of atomic nucleuses constituting atoms as the basic unit of cell and the electrons outside the nucleus are in constant high-speed movement and changing, thereby constantly emitting electromagnetic waves.

The electromagnetic wave signals emitted by the animal body represent the specific state of the animal body, and the emitted electromagnetic wave signals are different under the different conditions of the human body, such as health, sub-health, disease, etc. If we can determine these specific electromagnetic wave signals, we can determine the status of the body's life.

Quantum medicine considers that the most fundamental reason of falling sick is that the spin of electrons outside the atomic nucleus and the orbit change, thereby causing the change of atoms constituting a material, the change of small biomolecules, the change of big biomolecules, the change of all the cells and finally the change of organs. Because the electron is a charged body,

when the spin of electrons outside the atomic nucleus and the orbit change, the electromagnetic wave emitted by the atoms will change. The energy o f the electromagnetic wave changes caused by the changes of the animal body's diseases and physical changes in the nutritional status is extremely weak and usually is only nano gauss to microgauss. The frequency and energy of the

weak magnetic field of hair determined directly or by holding a sensor compare with the resonance spectra of standard quantum of diseases and nutrition indicators set in the instrument after the frequency and energy are amplified by the instrument and processed by the computer, and then the corresponding quantum value being from negative to positive is output. The size of the

quantum value indicates the nature and extent of the disease and the nutrition levels. Finally, the test results are resolved by clinicians. It's similar to the principle of listening to broadcasting from the radio. There are many radio waves in the air. If you want to listen to some designated broadcasting, you can transfer the radio to the corresponding frequency, at this moment, resonance occurs, so that you can listen to this broadcasting. Quantum resonance uses this principle for testing.
