Do you understand these? First, pay attention to the concentration of the medication. Here are some related experiences in flower planting for your reference.
Recently, the weather has been getting hotter and many pests and diseases of roses have started to outbreak, such as spider mites, thrips, black spot disease, and so on. In the face of these rose pests and diseases, we still need to spray medication promptly for treatment and prevention. What I want to talk about today is some precautions when applying pesticides.
The above is a question asked by a reader group of gardening friends. From the pictures, it can be seen that many young buds have started to turn black.
There are also spots of withered leaves on the leaves, and the leaf tips have turned yellow. These symptoms all appeared after applying pesticides, which indicates they are caused by excessive concentration of the medication.
So, how should you apply pesticides to avoid damage?
First, pay attention to the concentration of the medication.
Controlling the concentration is the key to avoiding damage.
Usually, the packaging of the medication has instructions for the mixing ratio, but most of them are calculated in mu (Chinese unit of area).
First, pay attention to the concentration of the medication.
Because pesticides were previously used for large-scale crops, the calculation unit is also in mu, which is too large for our home gardening.
If you have good arithmetic skills, you can certainly convert and calculate, but if you're like Green Plant Enthusiast Network and not good at math, you can only guess.
What if you don't know how to calculate the concentration?
If you're like Green Plant Enthusiast Network and can't calculate the concentration, the safe approach is to try first. Generally, the concentration of fertilizer is above 2000 times, and the same concentration can be referred to when mixing pesticides.
First, mix a concentration of about 2000 times and spray it on a single plant, then observe the effect. If the symptoms are reduced, you can continue to spray the medication at this concentration after a few days. If there is no improvement, you need to increase the concentration and try again.
Precautions when spraying pesticides:
When spraying pesticides, personal safety protection should be the first priority. It is best to wear gloves, a mask, long-sleeved shirts, and long pants. When spraying pesticides outdoors, make sure to stand upwind. It is not suitable to spray pesticides on windy days.
Not only personal safety protection should be considered, but the amount of pesticide used should also be controlled to ensure even spraying. Both the front and back of the leaves should be sprayed.
The speed of movement when spraying should be as uniform as possible to avoid staying too long in the same position, which can easily lead to excessive medication residue and damage.
Usually, when the concentration is appropriately mixed, just spray until the leaves are dripping.
Green Plant Enthusiast Network suggests that when applying pesticides, not only the rose plants should be sprayed, but the surface of the potting soil should also be sprayed to kill the bacteria and pests staying on the surface.
