Instructions for use

On-site mixing barrels use:
Add 50g of HH-408 to every 200kg of spray. If it is necessary to promote absorption, further improve efficacy or reduce spray volume, the dosage can be appropriately increased. In general, the dosage of fungicides is 0.01~0.05%, herbicides is 0.025~0.1%, and the insecticides is 0.025~0.1%.

When using, first add 80% water to dissolve the pesticide, then add HH-408 and 20% water to mix evenly.

HH-408 has the best effect under the following conditions: ① The pH value is controlled in the range of 5-9, ② It is used within 24 hours after preparation

To prepare pesticide formulations use:
It is recommended to add 0.5~8% of the pesticide stock solution to the pesticide stock solution,and adjust the PH value of the pesticide formula to 6~8. The user should adjust the usage amount of HH-408 according to the pesticide variety and formula to achieve the best Effect. Compatibility test should be done before use.
