Grape virus disease easily resolved

Grapes are not only of high nutritional value, but also have very good medicinal value. Therefore, planting is particularly common, but grape plants are always falling, fruit drop and very serious. It seriously affects the harvest and it is a headache. In fact, in the final analysis, these are grape viruses. Illness.

Grape virus disease mainly spreads in the soil by the nematode larvae. Both larvae and adults can spread and have fast speed and strong persistence. Sometimes the grafting technology is not well mastered and its juice can also promote the occurrence of grape virus disease, mainly manifested as veins. Distortion, abnormal branching, short or varying internodes, and falling fruit and fruit, etc., require us to have a good understanding of the knowledge of grapevine virus disease, so that we can take timely preventive measures when the virus occurs.

The use of non-toxic or anti-viral propagation materials to remove and limit the source of infection and to prevent and control the transmission of the virus are the most effective methods for easily solving grape virus disease. During the grape growing process, timely detection and removal of diseased plants, disinfection of the soil with a disinfectant such as methyl bromide or carbon disulfide to achieve the purpose of nematode eradication; before planting, the seedlings of the grapes to be propagated are placed at 35°C. In 20 days, the original leaf-leaf virus can be removed. The mid-week treatment method is called heat-treatment detoxification, and can also be detoxified by using shoot-tip culture. In addition, the establishment of a virus-free grape seedling nursery is an effective measure against grape virus disease. .

Greenhouse Ventilation Fan

Ventilation is one of the most important components in a successful greenhouse.
If there is no proper ventilation, greenhouses and their growing plants can become prone to problems. The main purposes of ventilation are to regulate the temperature and humidity to the optimal level, and to ensure movement of air and thus prevent build-up of plant pathogens (such as Botrytis cinerea) that prefer still air conditions. Ventilation also ensures a supply of fresh air for photosynthesis and plant respiration, and may enable important pollinators to access the greenhouse crop.
