The herbicide Glufosinate Ammonium SL is commonly used with a concentration of 200g/L. It is widely used in various crops such as pear orchards, tea gardens, lychee gardens, banana gardens, mango gardens, apple gardens, citrus gardens, grape vineyards, vegetable farms, mulberry orchards, papaya gardens, and peach orchards. For weeds in fruit orchards and tea gardens, 3000-4500ml /ha of stem and leaf directed spray is generally used, while for weeds in vegetable fields, 2250-3750ml/ha of directed spray is used.

Techniques for using Glufosinate Ammonium SL:

1). Fruit orchards and tea gardens: After the weeds have emerged, dilute with 450-750 L/ha of water and carry out stem and leaf directed spray treatment in between the trees or under the trees. 

2). Vegetable fields (between rows): During the growth period of vegetables, after the weeds have emerged, dilute with 450-750 L/ha of water, install a protective cover on the nozzle and carry out stem and leaf directed spray treatment between the rows of vegetable crops, avoiding spraying on the leaves of vegetables. 

3). Vegetable fields (field cleaning): After harvesting the previous crop and before planting the next, dilute with 450-750 L/ha of water, and spray stem and leaves of residual crops and weeds to clean the field.

4). Stem and leaf spray during periods of abundant weed growth, apply once.
