When is the best time to shoot wild wheat in spring?
Wild wheat can be threshed with fenoxaprop-ethyl, propargyl acid and other drugs. Generally, in the 3-5 leaf stage of wheat, it should be sprayed evenly on sunny days with an average temperature above 8℃, otherwise there will be wild wheat residue. It's best to take the medicine now, otherwise it will affect the efficacy and fail to achieve the prevention and control effect.
Suitable temperature for beating wild wheat:
Herbicide will be marked as 2℃ or 5℃, so 2℃ and 5℃ here refer to the lowest temperature, that is, the lowest temperature can only be used above 2℃, and it cannot be lower than this temperature two days before and after application.
Try to apply the pesticide when the weather is clear, the temperature should be above 4℃, the pesticide must be diluted twice, and re-spraying or missed spraying is not allowed. Water consumption should be sufficient during this period. Generally, plots with accumulated water and dew are typical weak seedlings, so this pesticide is not allowed to be used at this time.
