Grass production field weed control

There are a large number of weeds in the field that produce turf, and there is a large amount of occurrence, and particularly weeds and turfgrass grow together during the regeneration process behind the turf shovel. Manual weeding consumes labor and labor, and the grass control time is short and difficult.

Unfinished turf fields can be weeded in spring, summer and autumn. Preventing weeds must start from the prevention of weeds and the eradication of weeds. First, it is necessary to strengthen field management, promote the rapid development of turfgrass, and use grass to control the grass. Second, we must promptly remove weeds, use safe and effective pesticides, implement chemical weed control, and take the chemical control as the focus of comprehensive management.
Monocotyledonous weeds in monocotyledonous turfgrass can be sprayed with 10.8% S. capsularis to 50 to 60 mL or 6.9% humerus 50 to 60 mL per mu, and the herbicidal effect can reach 83% to 95%. The control of broad-leaved weeds in monocotyledonous turf is achieved by mixing the normal amounts of paraquat and 2A and 4 chlorine, or mixing it with conventional amounts of 2A and 4C. To control the Cyperaceae weeds in monocotyledonous turf, spray 15 to 20 grams per mu with 10% herbicide to achieve a herbicidal effect of 73.1% to 96%. Appropriate early application of pesticides and increased water use, significantly improved the weeding effect. Broad-leaf turfgrass field with 10.8% of high-efficient straw can be 50 to 60 ml or 6.9% of Hummer 50 to 60 ml, watered spray, anti-Dendrobium officinalis field monocotyledonous weeds good effect, and the safety of horseshoe gold it is good. There are many kinds of weeds in the turfgrass fields, and they have a long period of weeding and a large amount of weeds. Weeding with herbs can greatly save costs.
