How to properly process crops and plants?
It is necessary to prepare a working solution before processing crops. The drug must be diluted in a container that is not intended for cooking. After use, wash the container thoroughly. Experts recommend using disposable containers to dilute the drug and choosing suitable weather for spraying.
Treatment is not carried out on rainy days or at high air humidity. The optimal air temperature level is from 25 to 34 degrees Celsius. It is best to spray plants using a spray bottle. During operation, it is necessary to control the uniform distribution of the product. This treatment can be carried out on abundantly vegetating plants.
The leaves of indoor plants should be thoroughly wiped with the prepared solution on each side. If the product is not completely used up, the remains can be poured onto the soil in the pot.

The orchid must be treated against thrips, nematodes, mites, mealybugs , and scale insects. To obtain the finished solution, take 2 ml of the product and 50 ml of water.
There are situations when pests settle in the root part, so to destroy them, the flower and pot are immersed in water at room temperature for 30 minutes. Adults float to the surface quickly, so they must be collected and destroyed. Next, the plant is dried, pulled out of the pot and treated with the drug.
If pests live on the leaves and stems of the orchid, then they need to be washed every day for a week with the prepared solution. In case of repeated pest infestation, the treatment is repeated.
How to dilute correctly and consumption rates

It is important to note that each ampoule comes with detailed instructions for diluting and using the drug. Recommended dosages for dilution were obtained experimentally, so these recommendations should be strictly adhered to.
