Pretilachlor 37% EW is a selective pre-emergence herbicide that is commonly used in agriculture, particularly in rice cultivation. Here are some key details about it:

Product Features: It belongs to the Chloroacetamide group of herbicides. After application, it quickly spreads on the soil and disrupts cell division at the time of weed seed germination. This lack of cell division checks weed germination and growth, ultimately causing the plant to die.
Mode of Action: It’s a broad-spectrum selective pre-emergence to early post-emergence rice herbicide. It controls grass, broadleaf, and sedge weeds.
Usage: It is recommended for use between 0-5 days after transplanting of paddy. It exhibits highly efficient control of a variety of weeds like annual grasses, sedges, and broad-leaved weeds.
Safety: It is safe for the crop and environment. It has no adverse effect like stunting or yellowing of the crop, rather it gives a greening effect to the crop.

Please follow the manufacturer’s instructions for the best results and safety precautions. It’s always a good idea to wear protective clothing and equipment when handling and applying such chemicals. If you have any more questions or need further information, feel free to ask. 😊
