Orchid rot disease: The disease occurs in humid summer, autumn and rainy seasons. Black rot and soft rot are common. Black rot: caused by Phytophthora fungi. Occurred in the leaves, roots and growing points, the diseased part of the initial emergence of translucent spots, followed by expansion of the spots, the organization black rot. Soft Rot Disease: Caused by Erwinia spp. and Pseudomonas sp. In the early stages of disease, tiny brownish water-soaked spots appear on the leaves, which then expand into gray, moist patches. The skin that touches the skin will burst and the pus with odor will flow out. Control methods: First, keep the plants aerated and reduce the humidity. In the initial stage of disease, spray 50% Kedistan 500 times liquid, 50% TYTB 1000 times liquid, garlic water (soak the garlic with water and take the filtrate) and spray the leaf surface. Apply lesions. Orchid rotten root: Although orchids are hi moist, but its fleshy roots are afraid of embarrassment, too wet or rain water easily rot, and easy to induce black spot. Therefore, raising the potted soil should not be too wet. Winter orchids are in a dormant or slow growing stage, basin soil should be dry; spring, early summer is an important period for orchid rooting and leaf extraction, basin soil should be biased; but long-term over-wet, but also easily lead to rot, causing leaves yellow and even death . In the rainy season or the rainy season, the potted orchids must be protected from rain. Due to prolonged rain and humidity, black spots are most likely to occur on new leaves, and the phenomenon of "rotten clothes" is often found in the flower buds. Affect flowering and ornamental. However, if the basin soil is too dry, the metabolism of pseudobulbs or other tissues may be affected due to water loss. This may also lead to delicate tissue, poor plant growth, and even death. However, the autumn should be properly damp, because the autumn drought will have adverse effects on the leaf shrubs and flowering in the coming year. Therefore, people who cultivate orchids should understand that "winter is not wet and autumn is not dry". The above shows that orchids have different requirements for moisture (including humidity) at different times, so the amount of orchid watering should be strictly controlled. Improper fertilization of orchids, such as excessive fertilization and over-concentration, can cause root rot by pouring liquid fertilizers into the leaf sheath or splashing on the leaves. Therefore, fertilization should be performed along the basin.
