Symptoms: Stiffness and rigidity of the stems and leaves, obstruction of growth of the parietal leaves, outward curling of the leaves, malformation; yellowing of the lower leaves first; broccoli lacking boron, carrified plaques or cracking of stems and leaves; cauliflower deficient in boron, new leaves dry, flowers Browning of bulbs; broccoli lacking boron stem emptiness; late growth cauliflower lack of boron performance, obvious macular spots around the flower head; broccoli severely deficient in boron, inflorescence death, damaged stems, short and thick roots. Control methods: 1. The application of boron fertilizer crops due to different types of plants, the need for boron and endurance of the boron are greater differences, the most attention to the amount of problems, less does not work, more likely to incur poison. (1) Borax is generally used for land application, and the amount of 666.7 square meters is mostly between 0.5 and 2.0 kg. Boron applied in soil should be applied evenly, otherwise it may easily lead to excessive boron damage. The application of organic fertilizer can increase the effect of boron application. (2) Foliar spraying is generally sprayed with 0.1% to 0.2% borax or boric acid solution. Borax is hot water soluble, and it is advisable to dissolve it with hot water first. 2. Increase organic fertilizers to prevent excessive nitrogen application. The organic fertilizer contains boron, and the total boron content is between 20 and 30 mg/kg. After being applied to the soil, it can be released with the decomposition of organic fertilizers to increase the level of boron in the soil; Improve the effectiveness of soil boron. At the same time, to control the amount of nitrogen fertilizer, especially excessive ammonium, not only affects the imbalance of nitrogen and boron in vegetables, but also inhibits the absorption of boron. 3. Water Management In case of long-term drought, when the soil is too dry, it must be timely flooded and drought-resistant, kept moist, and increase the absorption of boron. For excessive boron treatment, lime can be used to inhibit the absorption of boron, but should be the main prevention. Monkeypox is a viral zoonosis (a virus transmitted tothose seen in the past in smallpox patients, typically-presents clinically with fever, rash and swollen lymphnodes and may lead to a range of medical complications.It is caused by the monkeypox virus which belongs totheorthopoxvirus genus of the Poxviridae family.Thereare two clades of monkeypox virus:the West Africanclade and the Congo Basin (Central African) clade.Theoname monkeypoxoriginates from the initial discovery ofthe virus in monkeys in a Danish laboratory in 1958.Thefirst human case was identified in a child in the Demo-cratic Republic of the Congo in 1970.
