Prevention and control of diseases and insect pests of edible fungi and orchids in summer

Orchids are managed more carefully in summer, when they peak. How to manage is a topic we have been talking about, the beginning of summer is from the beginning of plum blossom, then orchid disease will follow. Because the plum rain season air humidity is high, orchid growth is the most vigorous period of time, but also the highest incidence of a period of time. At this time, the temperature between 20℃-25℃, this is the golden period of disease, more than 30℃ bacteria reduced. In order to avoid the disease in the golden section, we should control the moisture, be sure to keep the orchid room clean, timely sterilization.

Speaking of sterilization, what should we use? Because there are too many fungicides on the market now, people are dazzled and unable to start. In fact, a lot of fungicides we haven't done clinical trials on orchids at all, just heard they're good to use. Unlike Taiwan, Japan is ripe for clinical trials. Are we killing fungal diseases, bacterial diseases, viral diseases and insect diseases? At this point, we must have a clear goal when we carry out sterilization.

1. Fungal disease control

This disease mainly consists of anthracnose, silk blight, leaf blight and other diseases. We should do a good job of prevention and control, orchid room ventilation light, keep clean, often give orchid bath. Usually available Dasheng 45, agricultural streptomycin, chlorothalonil, billion force, Dak Ling Jing, green enjoy 8 and other pesticides to prevent clean.

II. Bacterial disease control

These diseases are mainly composed of rot, black rot, brown rust and so on. If these diseases are discovered and treated early, there is still hope for survival. The main thing is to strengthen ventilation, control moisture, and immediately cut and burn the diseased leaves. at ordinary times, it uses pesticides such as yili, chlorothalonil, pujue, commander-in-chief, and dak ling to control it.

III. Virus disease control

In fact, there is no way to prevent this disease, in case of disease on the self-proclaimed bad luck, had to improve the orchid artists to identify the ability of bacteria, strengthen self-protection awareness. Do not introduce bluegrass with Byrus disease. this orchid was very popular in taiwan before, but after it was introduced to the mainland, it developed pathological changes. orchid plants can grow up without dying, and there are flower spots on their leaves. even mountain grass has this disease.

IV. Prevention and control of insect diseases

We see scale insects, whiteflies, ants, thrips, etc., which grow on the foliage and we can see most of them with the naked eye, which can be controlled. Hate to hate in the basin soil activities of the bugs, they are our orchid basin spread bacteria, leading to the incidence of bluegrass the biggest enemy, then we have to carry out insecticidal treatment of them, available pesticides have good winter, Le Si Ben and so on.

The above four virus pests can be simultaneously treated and controlled.
