How to weed winter wheat fields? 5 Ways to Increase Productivity!

Wheat belongs to the genus Gramineae and is one of the earliest cultivated crops in the world. after long-term development, wheat has become one of the food crops with the widest distribution, the largest area, the highest total yield, the largest trade volume and the highest nutritional value in the world. So how to weed the wheat field in winter? These five methods can safely survive the winter and increase the yield.

I. correct selection of pharmaceuticals

Wheat fields dominated by broad-leaved weeds can choose 40% carbendazim dry suspension or benzenesulfuron series product wettable powder; wheat fields dominated by malignant Gramineae weeds such as Triticum aestivum and Italian ryegrass, it is appropriate to choose 6.9% oxazolidin water emulsion or 3% Shima oil suspension.

Second, to achieve "three looks"

Take a look at the germination and emergence of seedlings. Wheat seedlings showed a certain resistance to herbicides at 3-4 leaf stage, and the safety of wheat seedlings could be ensured only when the herbicide was applied. Wheat has less tillers and less cover in the field, which is beneficial for weed seedlings to fully absorb the solution and avoid low temperature application as far as possible. "second look" soil moisture. If the soil moisture is poor, the water consumption must be increased when applying pesticide. In the "three look" weather, there must be 3-5 days when the temperature is 8-10 degrees, there is no wind or breeze.

Third, avoid single drug use

Sulfonylureas such as benzenesulfuron and trimethoprim should be used alternately with azolidone in order to delay the emergence of drug resistance and ensure stable control effect.

4. Secondary dilution must be adopted.

The second dilution technique must be used for herbicides in wheat fields. First, dilute evenly with a small amount of warm water in a small container, then add enough water into the medicine and shake it well to spray, otherwise it will appear the phenomenon of stripes.

5. Ensure the quality and progress of work

Check and maintain the medicine equipment before spraying, ensure its normal operation, resolutely put an end to dripping, leakage, blocking and other phenomena, operators should move forward at a uniform speed to prevent leakage or re-spraying.
