Last Safe Time for Herbicide Spray in Wheat Crop || Crop Reformer

Описание: nowing the right time to spray herbicide in wheat crop is extremely important for getting maximum weed control and avoiding yield loss. Many farmers ask, “How late can we spray herbicide on wheat?” The simple answer is: herbicide should be sprayed at the early weed stage and early wheat stage, but if delayed, results become weak and losses increase. In this video, we will explain the safest and latest stage for herbicide spray in wheat under Pakistan’s conditions.

Ideally, herbicide spray should be done between 25 to 40 days after sowing, when weeds are small and wheat is at the 2 to 4 leaf stage or early tillering stage. This is the most effective window because weeds are actively growing and easily controlled. If we delay beyond this stage, weeds become strong, and herbicide cannot kill them completely, even with higher doses.

Many farmers spray very late, around 50–60 days after sowing, which is risky. At this stage, wheat is in full tillering and stem elongation, and weeds are already competing heavily for nutrients, water, and sunlight. Late spraying not only reduces herbicide effectiveness but can also cause crop stress, yellowing, burning, and yield reduction, especially in foggy and cold winter conditions.

Another important factor is weed size and weather. Even if wheat age is suitable, large weeds (more than 3–4 leaves) and foggy, cold, or cloudy weather reduce herbicide performance. Temperature should be above 10–12°C, with no fog or rain for at least 24 hours after spray. So, instead of only looking at days after sowing, always judge the growth stage of weeds and wheat.

In short, the last safe time to spray herbicide in wheat is the early tillering stage, before the first node appears. After this, chemical control becomes less profitable and more risky. If you are already late, it is better to focus on nutrition, irrigation, and crop management rather than wasting money on a weak spray.
