Attention must be paid to the following points during use: 1 glyphosate is a herbicide herbicide. When the dosage per hectare exceeds 11250 ml, it will cause phytotoxicity to the tea tree. When applying, the dosage should be controlled, and the nozzle should be lowered or A safety cover is added to the nozzle to prevent the liquid from drifting onto the tea tree to avoid causing phytotoxicity. 2 Choose sunny or cloudy application, such as 6-8 hours after spraying, it must be sprayed with rain. Do not loosen the soil within 60 days to fully exert its internal absorption. 3 Add 0.2% washing powder or additives when dispensing, which can improve the weeding effect. 4 After spraying, the sprayer should be cleaned to avoid the use of the same instrument to spray insecticides, fungicides, etc. to cause phytotoxicity.
