Disease and insect Management of Orchid

There are many diseases and insect pests that harm orchids. If they are not controlled in time, orchid plants will suffer serious losses. The common diseases are virus disease, white silk disease and leaf spot disease. Prevention should be carried out by improving cultivation conditions and strengthening daily maintenance.

At the initial stage of the disease, the virus disease was sprayed with 1000 times of aspirin, chloramphenicol injection was used for white silk disease, 1 dose of chloramphenicol with 1kg water, and gonorrhea plants were irrigated once a day for twice a day, and penicillin was used for leaf spot disease. Spraying with 2000 times of mycin solution, once every 2 days and spraying 3 Mel for 4 times in succession, can have a better effect. The main pests are shell insects, aphids and red spiders.

If there are few shell insects, remove them one by one with toothpicks or toothbrushes, and spray them with malathion 50-700 times solution in large quantities. The aphids were sprayed with 5OO, a 10% wettable powder produced by Jiangsu Kesheng Group, and the effect was very good.
