Understand Orchid Medicine (first, opening words)

Most of the diseases and insect pests that can be parasitized on plants can be parasitized on bluegrass, but the frequency of visiting bluegrass is different. At present, there is no true sense of orchid medicine, the so-called orchid medicine is basically the use of agricultural drugs.

With the continuous change of the ecological environment, the microflora and insects are constantly changing their viability in the process of adaptation. As the object of our conservation, plants become weaker and weaker under the action of all kinds of drugs, and become more and more dependent on the role of drugs. At the same time, as the object of our killing, diseases and insect pests are becoming more and more powerful, and the effect of drugs is becoming more and more powerless.

So people continue to develop new drugs and use new pharmacology to restrict the antibodies produced by diseases and insect pests. Parasitic fungi on plants can be divided into fungi or bacteria, while insect pests can be divided into juice-sucking and leaf-eating (root) types.

Pesticide components are made of organic and inorganic separately or mixed, and their conduction can be divided into internal absorption and non-internal absorption, and their effects are contact, blocking, interference, blocking, slowing down, affecting bacteria cells and so on. Pesticides can be divided into two categories: fungus control and bacteria control.

When we use drugs on diseased orchids or protection, we should make a correct discrimination of diseases and insect pests, have a general understanding of the pharmacology of the drugs used, and only by using the selected drugs without losing time can we carry out effective prevention and control and minimize the losses caused by diseases and insect pests.

As people pay more and more attention to environmental protection, agricultural drugs are gradually developing in the direction of low toxicity and safety, and new green environmental protection and pollution-free biological fungicides are also applied. In the process of orchid control, we have used some different kinds of pesticides with different pharmacology, and have had some personal practice, gains and losses. I hope to discuss with orchid friends to improve our level in orchid pest control.

The transmission of diseases and insect pests is nothing more than primordial and invasive. Unclean plant materials and unclean environment are hotbeds for breeding diseases and insect pests, bluegrass is the key to resist diseases and insect pests, and air temperature, humidity, management gains and losses are the factors of the frequency of diseases and insect pests.

We have to use drugs when germs occur or are prevented. The drugs we use should pay attention to the effective source point and expiration date of the drugs. Far away thinks that it is best to purchase drugs from local pesticide stations or reputable websites, and the varieties used should be introduced by the local Laolan family or obtained through other means. After obtaining the drug, we should be familiar with the information which may affect the effect of use, such as pharmacology, medicine, proportion, interval, matters needing attention and so on.

Pesticide stations have small packages of pesticides, most of which are about five grams, and some range from 50 grams to 100 grams. It is not recommended to buy them in the flower and tree market, where the medicine is often out of date or counterfeit. Bag charge is often not much to use at one time, and needs to be used in batches, so it is difficult to grasp the accuracy of each dose. There is a small door far away: if it is packed in a small bag of about five grams, you can pour all the medicine into a disposable plastic syringe (the lower part needs to be closed). The scale in the syringe will tell you the volume of the medicine, and the accuracy is very high. Another way is to use the small measuring tools brought in the Huabao box, but the volume of each drug is different, so it is best to measure all the dosage before use so that you have a good idea.
