Terms of Use
The acaricide's instructions specify application rates for each crop. To achieve the desired results, it's important to follow these recommendations. Application rates are presented in the table:
| Plant | Type of ticks | Dosage per 1 hectare | Number of treatments |
| Grape | Spider mites Felt pliers |
0.25-0.38 kilograms
0.38-0.5 kilograms |
No more than 2 times |
| Soybeans | Spider mites | 0.4-0.5 kilograms | 1 time per season |
| Apple trees | Red fruit and hawthorn mites | 0.38-0.5 kilograms | No more than 2 times during the growing season |
The first treatment with the product is recommended in the spring, when approximately 80% of the parasite larvae have emerged. In the summer, plants should be treated if they are infested by the summer pest population.
To maintain its effectiveness, prepare the working solution for crop treatment before spraying. First, fill the sprayer tank with clean water—halfway full. Then, add the acaricide.
Since the sachets dissolve in water, there's no need to empty the powder. To prepare the solution, turn on the stirrer and wait until the chemical is completely dissolved in the water. Then, add the remaining liquid and stir again until the solution is smooth. Immediately after completing the mixing process, begin spraying the area.
It is recommended to treat plantings at temperatures between 10 and 30 degrees Celsius. Morning or evening is best. Wind speed should be kept to a minimum. This will prevent acaricide droplets from spilling onto adjacent beds.
Precautionary measures
When using any chemical to treat crops, it's important to follow safety precautions. Protect your body and hands with overalls and rubber gloves. To prevent fumes from irritating your respiratory tract, wear a mask or respirator.
During the work, do not drink water or eat anything. Smoking is also prohibited. After completing the treatment, all clothing must be washed. A shower is also required. If any droplets of the working fluid accidentally come into contact with skin or mucous membranes, rinse the affected areas with running water and consult a doctor.
What is it compatible with?
Acaricide can be combined with other chemicals. However, a compatibility test must be performed first. Masai is approved for use with products such as Delan, Kumulus, and Acrobat MC.
