| Main targets & applications | For annual gramineous weeds and some broadleaf weeds in rapeseed fields, 540~810 g/hm2 should be sprayed on the soil after transplanting. Annual grass weeds and some broadleaf weeds in peanut fields should be treated with soil spraying at 780~1275 g/hm2. Annual grass weeds and some broadleaf weeds in cotton fields, 810~945 g/hm2 (southern Xinjiang), 945~1080 g/hm2 (northern Xinjiang) soil spray treatment before sowing. Annual grass weeds and some broadleaf weeds in corn fields, 1 350~1 620 g/hm2 (Northeast region), 810~1 350 g/hm2 (other areas) soil spray treatment. Annual grass weeds and some broadleaf weeds in soybean fields, 1 350~1 890 g/hm2 (Northeast region), 810~1 350 g/hm2 (other areas) Soil spray treatment |
