Mainly harm the leaves, but also harm the stem and head. The initial stage of the disease is white, and then the color gradually changes to light brown, and black ascus can be formed by self-breeding or hybridization. In general, the lower blade is more than the upper blade, and the back of the blade is more than the front. The mildew is dispersed separately in the early stage, and then combined into a large mildew, which can even cover the whole leaf, seriously affecting photosynthesis, interfering with normal metabolism, causing premature aging and loss of yield ! Sulfur powder is widely used in the fields of flowers, trees, fruit trees, soil formulation improvement, etc. (1) Sulfur powder is an acidic compound, used in flowers, trees, fruit trees, with sterilization and anti-corrosion, acid and alkali conditioning, promote wound healing, disease prevention and control effect, but also can supply plant nutrients, promote growth and development. (2) Avoid injury. The roots, branches and leaves of plants with simple wound flow, such as figs, grapes, banyan trees, cycads, etc., can be pruned and coated with sulfur powder on the wound, which can inhibit the occurrence of wound flow, avoid wound infection and decay, and promote healing (3) prevent root rot. Clivia and other potted flower techniques, due to waterlogging, disease root rot, yellow leaf scene, combined with pot change soil, cut off rotten roots, spray sulfur powder on the wounds and roots, can control rotten roots, promote new roots, rapid recovery and growth. When the tree has root rot and yellowing, dig the root soil, cut the root rot, and spread sulfur powder on the root to cover up the fresh sterile soil, which can avoid continuous root rot and recover normal growth. (4) Prevent cutting and flower arrangement from decay. When cutting camelia, rhododendron and other forest fruits and flowers, the cutting base is dipped in sulfur powder and then cut, which can avoid the decay of cutting and greatly improve the survival rate. Dipping sulfur powder on the base of flower arrangement can avoid cutting rot, reduce fading speed, and extend the appreciation period of flower arrangement. (5) Prevention of powdery mildew. For plants with simple powdery mildew, such as flowers, trees, melons and fruits, spraying sulfur powder when the leaves are wet or there is dew, spraying with rubber special sulfur powder suspension or lime sulfur mixture in dry weather has special effect on preventing powdery mildew. (6) Applied to prevent salt and alkali damage in soil. Applying a certain amount of sulfur powder in saline-alkali soil can regulate soil PH value, reduce salinity and promote the normal growth of forest fruit flowers.
