Problems needing attention in using herbicide Hummer in wheat field

1, Hummer is not suitable for oats, corn, barley, sorghum and other crops, so as to avoid phytotoxicity and unnecessary damage, and it is safe for the next crop.

2. After thoroughly cleaning the used packaging bottles or bags, pour the cleaning solution into the spray box.

It is best to do it at 8- 17 in the sun. The air humidity is high and the temperature is high, which is beneficial to the drug effect. Shake it well when taking medicine, and don't spray it in the wind. You need to spray when the wind is light. When the wind speed is higher than 4m/ s, it is necessary to stop the application and adjust the dosage according to different conditions. Generally, manual spraying is about 50l per mu.

4. Hummer herbicide is toxic, and unused chemicals must be kept in the original packaging. Be sure to stay away from food, feed, drinks and places that children can reach.
