Why to rose hit medicine, did not see better instead more serious?

We often talk about pest prevention, so many novice flower friends regard pests and diseases as the same, in fact, we say pests and diseases, should include two completely different conditions.

Diseases and pests are divided into diseases and pests, the two have essential differences, and the drugs are naturally different.

There are often flower friends consulting blue demon rose disease and insect problems, blue demon also often encounter such problems:

When a flower friend asked me about rose problems, I told him it was rose black spot disease, and then he would ask me: "I played a hundred insects, but no effect ah?"

There are flower friends, when the blue demon told him rose is got red spider, he will tell me that he has been hit medicine, but is not better, but more serious, ask him what medicine to hit know that it is sprayed with carbendazim.

As readers say, diseases and pests are not distinguished, indiscriminate use of drugs is really not a case. Blue Demon also felt that it was time to popularize the difference between diseases and pests.

What is the difference between disease and pest?

What is disease?

It refers to a series of morphological, physiological and biochemical pathological changes of plants under the influence of biological or abiotic factors, which hinder normal growth and development, and even present abnormal pathological phenomena in external morphology, such as wilt, rot, spots, mildew, mosaic, etc., collectively referred to as diseases.

What is pest?

Simply put, it is harmful to plant growth or production of animals, mainly insects, in addition to mites, snails, rodents and so on.

To give a simple example: disease is like we have a fever, the source of infection is invisible bacteria, germs, and pests are like mosquitoes, wasps, etc. that bite us, exotic small animals.

Knowing this difference, we should know that when treating diseases and pests, the drugs used for diseases and pests are completely different.

Disease medication:

Disease is caused by bacterial infection, in the drug on the multi-use of bactericidal agents, such as the name of the drug with bacteria, chlorothalonil, carbendazim, and so on.

Of course, there are many names of fungicides that do not contain bacteria. We can read the instructions and write broad-spectrum antibacterial drugs, which can be used to treat diseases.

This is the main principle of disease use, of course, different diseases will be a little different, but the general direction is good, generally there will be some effects, the effect of sexual drugs can be better.

Pest application:

Insect pests should be used pesticides, such as 100 insects Ling, soil insects Dan, these names with the word insect, are insecticidal drugs. Some of the names of acaricide drugs have more than one mite, such as: pyridaben, love card mites, acaricide and so on.

Some insects need targeted drugs, such as green insects that eat leaves, need to use drugs to kill insects, very small insects can generally be killed by pesticides, mites need drugs to kill mites.

Although the specific medication will be different, Blue Demon hopes that everyone can understand that there is an essential difference between diseases and pests. We should fully realize this before treatment, so that effective treatment can be possible.
