Correct Thinking on Using Pesticides for Rose Diseases and Pests
For many girls, the introduction of green plants and flowers with the correct approach to using pesticides for rose diseases and pests is followed by an introduction for everyone to understand together.
There is an insurmountable obstacle in raising roses, which is the problem of rose diseases and pests. Many people say that roses are like medicine jars, and the medication cannot stop. However, for many新手 gardening enthusiasts, how to use pesticides is a big problem.
Recently, I often encounter gardening enthusiasts who use carbendazim to control aphids and then say that it doesn't work after spraying, which is indeed a headache. Today, I will briefly talk about the issue of using pesticides for rose diseases and pests, which I believe will solve 90% of your questions about pesticide use.
One: Correct Thinking on Using Pesticides for Rose Diseases and Pests
We often say "diseases and pests," which makes many新手 gardening enthusiasts feel that diseases and pests are the same thing. They think carbendazim and chlorothalonil are universal remedies, and they just spray carbendazim no matter what the problem is.
In fact, diseases and pests are completely different. To give a simple example, if peaches have worms inside and are being eaten by worms, we capture or kill the worms, and then the pest problem is considered resolved.
But if peaches rot or grow mold, that is a disease. Diseases are divided into fungal diseases and bacterial diseases. In the book "How to Grow Roses from Scratch," there is a classification of diseases and detailed introduction of various diseases and pests. Interested friends can read and refer to it. Today we will only discuss the correct approach to using pesticides, as having the correct management approach can save a lot of detours.
Both fungal diseases and bacterial diseases are collectively referred to as diseases and are infectious. For rose diseases, we should practice regular prevention and promptly detect and manage them.
Therefore, in summary, the purpose of managing pest control is to kill pests, while the purpose of managing diseases is to kill bacteria.
Alright, remember this overall approach to managing rose diseases and pests; this is very important and is the first step in effectively treating rose diseases and pests.
After remembering this overall approach to managing rose diseases and pests, let's then talk about the issue of using pesticides.
Two: Methods for Managing Rose Pests
Rose pests come in many types. What kind of pesticide should be used to treat them? This is another troublesome issue. Here, I will give you a simple management plan.
Common rose pests can be simply summarized as common pests, such as aphids, caterpillars, and flying insects. These types of pests are relatively easy to manage, and the effect of pesticide spraying is very obvious.
As for choosing what pesticide to use, it's actually not necessary to worry too much. I personally suggest that for small insects like thrips and aphids, you can use pesticides like abamectin and acetamiprid. For larger insects like beetles and caterpillars, you can use pesticides like beta-cypermethrin and phoxim to kill them.
Many pesticides can kill multiple types of pests at the same time. For home gardening, there is no need to turn your home into a pesticide store. Having one or two pesticides that can solve the problem is enough. When in doubt, use a pesticide first to see if it works, and then consider changing it if necessary.
But here, note that the red spider mite is different from common pests. It is a mite that requires a specific miticide to be effective.
Three: Pesticide Use for Managing Rose Diseases
Rose diseases should be prevented more than treated. Carbendazim, which is considered a universal remedy by many gardening enthusiasts, is a fungicide used mainly for prevention. Therefore, in the daily management of roses, we generally use carbendazim and zineb for prevention, as these two fungicides have strong protective properties.
When roses actually develop diseases, using carbendazim and zineb again will not be very effective. It makes sense because carbendazim and zineb are preventive medications and serve as the first line of defense. If roses have developed diseases and pests, it means the first line of defense has been breached. At this point, we should use fungicides with better fungicidal effects to treat the diseases.
So, what fungicide should be chosen? And often it is not clear whether it is black spot disease or (T-J) disease or other diseases. What should we do?
Actually, you don't need to worry too much. Most of the common fungicides on the market can kill multiple types of pathogens at the same time. This means that one medicine can treat black spot disease, (T-J) disease, and powdery mildew, so what difference does it make which disease it is? As long as it's effective.
Just be careful when choosing pesticides and try not to choose those with names like "xxx霉素," which are usually targeted against bacterial diseases. The fungicides we commonly use, such as fluoroquinazol, pyraclostrobin, and myclobutanil, are mostly effective against both bacterial and fungal diseases. For home gardening, why use two pesticides when one can solve the problem?
The above sharing on the correct approach to using pesticides for rose diseases and pests, methods for managing rose pests, and the comprehensive introduction of pesticide use for managing rose diseases are hoped to bring some knowledge about green plants to green plant enthusiasts.
