Symptoms 1. Celosia leaf spot, also known as brown spot, affects the leaves, petioles, and stems. Initially, small round lesions appear on the leaves, which later expand into irregular spots with ring-like patterns. The color of the lesions changes from reddish-brown to dark brown, with a gray-brown center. On the stems and petioles, the lesions appear as long, brown streaks. 2. Fishtail leaf spot, commonly referred to as black spot, causes dark brown spots on the leaves that gradually grow into large, irregular patches. These patches have slightly raised edges, and small black spots are scattered across both sides of the leaves. 3. Clivia leaf spot, also called wilted spot disease, begins with elliptical or elongated reddish-brown lesions on the leaves, often surrounded by a green border. As the disease progresses, these lesions expand into irregular, larger patches with dark spots in the center. Disease Occurrence Patterns Sphaerotheca fuliginea spreads through wind and rain, infecting plants during the following growing season. Celosia brown spot is most severe in summer and autumn (August–September), while the spotted leaf disease of Kiriophora tends to occur in hot, humid conditions. Clivia leaf spot typically appears in spring and autumn, but can occur year-round in greenhouse environments. Factors such as continuous cropping, overcrowded planting, poor air circulation, and high humidity significantly contribute to disease development. Control Methods 1. Promptly remove and destroy infected plant parts to prevent further spread. 2. Implement crop rotation practices, especially when growing in greenhouses. 3. Avoid excessive watering and over-spraying, as this can increase humidity and promote fungal growth. 4. Begin fungicidal treatments at the first sign of infection to prevent the disease from spreading. Commonly used fungicides include 25% carbendazim WP diluted at 300–600 times, 50% carbendazim at 1000 times, 40% wettable powder at 600–800 times, 50% thiophanate-methyl at 1000 times, 70% SENOX at 500 times, 80% mancozeb at 400–600 times, and 50% kresoxim-methyl at 500 times. It's important to alternate between different fungicides to reduce the risk of pathogen resistance.
In the Arbas region of 105° east longitude and 40° north latitude where the temperature fluctuation between day and night can reach 50 degrees in winter, there is an essential native goat breed, the purebred Arbas Baby Cashmere Goat, which features thin and soft hair, a pair of horns and pink ears.

What is Cosmetic raw materials?
The famous Arbas Baby Cashmere Goat, as a rare breed living in the Ordos Plateau of Inner Mongolia, is concentrated in Otog Banner, Otog Front Banner and Hanggin Banner in the western part of the Plateau. Sumu, Arbas, Otog Banner is the primary production area of Arbas Baby Cashmere Goat for its favorable natural environment, with Arbas Mountain in the west, vast natural pasture in the center and desert steppe in the south. The semi-arid steppe climate provides excellent conditions for animal husbandry.
Due to its location in the desert steppe, the area is dry and windy with little rainfall and much sand. The temperature difference between day and night is extremely high, and the annual average temperature is 6.4 °C. In the long, cold and dry winter, the lowest temperature reaches -30°C to -40°C late at night, while in the short, hot and arid summer, the highest temperature is 36.4°C and the lowest -32°C, with annual precipitation between 200mm to 400mm. The adorable, lovely and lively Arbas Baby Cashmere Goat grows in such extremely harsh conditions, thus can produce rare and quality cashmere.
Arbas Baby Cashmere Goat`s two coats are pure white. The top layer or outer coat is bright and coarse guard hair to protect the undercoat that is softer and finer down. The quality of the cashmere fleece is determined by three indicators: the diameter, length, and density of cashmere fibers. Due to its unique genes, Arbas Baby Cashmere Goat has a superiority that can never be duplicated. Its secondary hair follicle is smaller than those of other goats, and its cashmere has an average diameter between 13μm to 15 μm. It can even produce cashmere with a perfect diameter of 14.5μm, with a pure cashmere content of over 55%, which is unique worldwide. The preciousness of cashmere results from the small amount of production of each goat. Therefore, Inner Mongolian Arbas Baby Cashmere Goat was officially named by the People`s Government of Autonomous Region in 1988 and was listed on the National Register for the Conservation of Animal Genetic Resources as Class-1 protected breed by the Ministry of Agriculture in 2001.
