Carnation, also known as carnation, is a major species of cut flowers. It is seriously damaged by Botrytis cinerea. After the buds, petals, stems and leaves are covered with gray mold, brown water stains appear, resulting in petal decay and flower bud loss. The stems and leaves withered, the susceptible buds could not be opened, the flowers of the diseased flowers were out of color, and the disease was severe when the temperature was high, the humidity was high, the spread was rapid, and the pests must be controlled to protect the stems, leaves, buds and petals to promote flowering and extension. Flowering period, increase ornamental value.
Specific prevention and control methods: Spray 1000 times potassium permanganate solution once a month, or 1,000 times the sodium bicarbonate (baking soda) solution, or 25-30 times the pure and clear ash leaching clear liquid, evenly spray all the leaves, Buds and petals are suitable for dropping drops of water from the beginning, which can effectively control the occurrence and damage of the gray mold of carnation and protect stems, leaves, buds and petals. If there is much rain, high temperature, high humidity, and gray molds appear on the stems, leaves, buds and petals, it is necessary to spray 2-3 times quick-drying clorox, 1500 times faster than Shennongsu chelating fertilizer and 300 times more phosphoric acid. Hydrogen and potassium fertilizer, 1000 times more than procymidone, 1,000 times stronger and stronger, 500 times more efficient mixture of biological phosphorus and potassium for prevention and control, spraying once every 7-10 days to kill the bacteria and make the disease quickly return to normal growth Promotes stems, leaves, buds and petals to promote flowering.
