In recent days, with continuous rain and rain, some weeds in the cotton fields are growing so quickly that cotton farmers must take timely measures to rescue cotton seedlings. The specific method is as follows:
The first is to strengthen the dredging of the cotton field ditch, reduce the groundwater level, as soon as possible filter water cool soil; second, grab the eye in the cotton wide line using mechanical cultivator weeding, combined with top-dressing raising seedlings; third is to artificially grab the weeds between plants.
The second is cotton field that has not been applied with herbicide before cotton seedlings are transplanted.
For cotton fields dominated by grasses and weeds, we can control them with chlorfenapyr (rabbitrin) and high-efficiency herb (Perfluorochloropyrrolidone). When the soil moisture content is insufficient, it is necessary to appropriately increase the dosage per acre.
For the broad-leaved weeds-based cotton fields, 24% Kekuile ​​(milfloxacin) EC can be used, 30 kg per mu 30 to 40 ml water, sprayed in the vicious weeds at the 2 to 4 leaf stage. If broad-leaved weeds are mixed with grass weeds, 24% Kekuile ​​Emulsifiable Oil 30 ml and 10.8% high-efficient gaisengerg EC can be used per mu, and 30 kg of water can be sprayed.
If weeding with glyphosate, in order to prevent burns and cotton seedlings, we must pay particular attention to several points. One is to spray on cotton in wide rows, and the other is to spray on weeds. Third, we must add a protective cover on the spray head to prevent liquid splashing. To cotton seedlings.
