Can propargyl be used in corn fields?

Clodinafop-propargyl is mainly used in wheat, rye, triticale and other grain fields. After seedling, the stems and leaves are treated to control annual gramineous weeds, such as wild oats, black oats, green bristlegrass, gramineous and milkweed. At present, there is no report that it cannot be used in corn fields. Clodinafop-propargyl has strong adaptability, can be compounded with a variety of herbicides, expand the weed control spectrum, and even kill weeds and weeds at the same time. If it is to be used in corn fields, it can be used in conjunction with corn herbicides. The active ingredients compounded with it mainly include fenoxaprop-p-ethyl, fenoxaprop-p-ethyl, diflubenzuron, trifluoling, octanoyloxonitrile+fenoxaprop-p-ethyl 2- methyl -4- chloropropyonate, bensulfuron-methyl, 2- methyl -4- sodium chloride, bensulfuron-methyl+fluoroglycofen, fomesafen, bensulfuron-methyl and tribenuron-methyl.

Optimum spraying time of herbicide after maize seedling

Because it takes 2-6 hours for herbicides to be absorbed after spraying corn seedlings, whether the herbicides are effective (that is, whether the weeding effect is ideal) is closely related to the temperature and air humidity within these 2-6 hours.

Spraying in the morning, noon or afternoon with high temperature and dry weather, due to high temperature and strong light, the liquid medicine will volatilize quickly after spraying, which limits the amount of herbicide entering weeds and obviously reduces the absorption, thus affecting the weeding effect; At the same time, when spraying pesticides at high temperature and drought, corn seedlings are also prone to phytotoxicity.

The best spraying time is after 6 o'clock in the evening, because the temperature is lower and the humidity is higher after spraying at this time, and the liquid medicine stays on the weeds for a long time, so that the weeds can fully absorb the herbicide components and ensure the weeding effect. Applying pesticide at night can also significantly improve the safety of corn seedlings and prevent phytotoxicity.
