Chemical weeding before and after sowing and growing period of Bupleurum
1. Chemical weeding on wasteland, second wasteland or leisure land with more persistent root weeds can be sprayed with 1000 ml of glyphosate water agent per mu in the first 15 days of soil preparation or during the period of exuberant weed growth. ("Nongda" and "Feida" are also similar products), which can kill most of the annual and perennial weeds. For ripe land with more young weeds, 250 ml of contact-killing herbicide "gram without trace" of 20% per mu can be sprayed two days before soil preparation, which can kill all green weeds on the surface and alleviate the shortage of grass at seedling stage.
2. Chemical weeding before seeding, after sowing and before emergence of Bupleurum, glyphosate or "gram without trace" can also be sprayed according to weed species to kill weeds unearthed before seedlings and reduce grass shortage at seedling stage.
3. Chemical weeding during the growing period, after the emergence of Bupleurum, the same kind of broad-leaved weeds can only be pulled out manually. But for Gramineae weeds, 12.5% "cover grass energy" EC 50 ml per mu, or 15% "Jingshengshi" EC 45 ml per mu, or 10% "refined grass gram" EC 50 ml, or 20% "Naazaojing" EC 100 ml, 30 kg of water, can be sprayed evenly on weed stems and leaves with manual sprayer to kill all kinds of grass weeds. The herb has strong drug resistance and still needs to be pulled out manually.
