Apply one round of Gramoxone to control weeds before sowing or transplanting rapeseed
20% Gramoxone aqueous solution is a contact, non-selective herbicide. When rice, cotton and other crops are harvested and the stubble is cleared, spraying Gramoxone before no-till direct seeding or transplanting rapeseed can build soil fertility, improve soil structure, increase aeration, and preserve fertilizer and water. Compared with plow-tillage rapeseed cultivation, it saves labor and cost, especially in rural areas where labor has been greatly reduced...
20% Gramoxone aqueous solution is a contact, non-selective herbicide. When rice, cotton and other crops are harvested and the stubble is cleared, spraying Gramoxone before no-till direct seeding or transplanting rapeseed can build soil fertility, improve soil structure, increase aeration, and preserve fertilizer and water. Compared with plow-tillage rapeseed cultivation, it saves labor and cost, especially when rural labor has been greatly reduced and seasonal conflicts are prominent, since this method allows sowing and transplanting in time for the farming season. If a systemic non-selective herbicide such as glyphosate is applied before sowing or transplanting rapeseed, sowing or transplanting can generally be done only 5-7 days after application; otherwise it will seriously affect rapeseed greening, prolong the seedling recovery period, and make it difficult to achieve strong seedlings for overwintering. In contrast, rapeseed can be sown or transplanted 4-5 hours after applying Gramoxone, with no adverse effect on rapeseed seedlings. If rain occurs within 8 hours after applying glyphosate, the application must be repeated.
No-till direct-seeded rapeseed: the methods of first killing then sealing and of combining sealing with killing can be used. First killing then sealing. After the previous crop is harvested, use 150-200 ml of 20% Gramoxone aqueous solution per mu, add 50-60 kg of water, and spray; this can kill all weeds and serve to clean up the previous crop. Rapeseed can be sown the next day after application; after sowing rapeseed, select herbicides such as dicamba, metolachlor, napropamide, acetochlor, and butachlor for soil sealing treatment. Combining sealing with killing. After sowing rapeseed and covering with soil, use 150-200 ml of 20% Gramoxone aqueous solution per mu, mixed with herbicides such as metolachlor, napropamide, napropamide, acetochlor, and butachlor; this saves labor and time.
No-till transplanted rapeseed: after rice, cotton and other crops are harvested, use 150-200 ml of 20% Gramoxone aqueous solution per mu, add water and spray to kill weeds, and transplant rapeseed the next day after application. After transplanting rapeseed, select herbicides such as napropamide, napropamide, and acetochlor for soil treatment; or mix Gramoxone with Guangjia'an and apply once by combining sealing with killing, then transplant rapeseed the next day after application.
