The products have their own merits and should be selected based on local actual conditions and costs. Cisulfuron-methyl is currently the world’s second-largest corn field herbicide second only to nicosulfuron, and its domestic patent period is about to end.
Aminotrione is a triketone herbicide. It is a new high-efficiency and safe post-emergence herbicide for corn fields in the world. Spraying in the whole field will not cause phytotoxicity and will not harm the seedlings. At the same time, this product overcomes the Mesotrione and other herbicides are easy to volatilize when exposed to rain and kill weeds more thoroughly! The selection coefficient of aminoacetate soil treatment or stem and leaf treatment for corn is greater than 4, and it is safe for corn. One application can effectively control the 1-9 leaf stage (the best control period is the 2-6 leaf stage) in corn fields. It has outstanding effects on annual and perennial grassy weeds, broadleaf weeds and sedge weeds, and has excellent effects on Cyperus rotundus and volunteer wheat seedlings. It is the latest mainstream brand of herbicide in corn fields.
Weed control:
1. Annual grassy weeds, barnyard grass, crabgrass, wild oats, goosegrass, wild sorghum, Salsola, volunteer wheat seedlings, etc.
2. Annual broad-leaf weeds: Ligusticum, Commelina, shepherd's purse, nightshade, wind lily, purslane, Amaranth amaranth, etc.
3. It has special effects on malignant weeds such as cyperus rotundus, volunteer wheat seedlings, and sedges.
Crops used: corn (spring corn, summer corn)
Dosage: spring corn, 200-250ml/acre;
Summer corn 180-220ml/acre .
Usage: Spray the stems and leaves of corn 1-9 (preferably 2-6 leaves) and weeds 2-4 leaves. Increase the dosage as the weeds grow, and the water consumption is 30kg/acre.
Notes:
1. This product is an early post-emergence weeding product. Please use it as early as possible. It is recommended to use it during the best period for better weeding effect and safer.
2. When applying, please avoid mist droplets from drifting to other crops: after the corn has 6 leaves, avoid drifting to the heart leaves of the corn, which will ensure a high yield of corn;
3. This product has strong permeability and will not be affected by rain 4 hours after application.
4. This product cannot be used on sweet corn, popcorn, sticky corn, seed corn and inbred corn.
5. This product cannot be mixed with organophosphorus and carbamate pesticides. These two types of pesticides are not allowed to be used 7 days before and after spraying this product. Do not mix other pesticides before testing.
6. Under normal climate conditions, this product is safe for subsequent crops, but it cannot be used to grow rapeseed, beans, and tobacco.
7. Do not discard the liquid medicine or empty packaging in the water or wash the spray equipment in rivers and ponds.

Mesosulfuron-methyl
It is safe for corn and the safest for spring corn. The half-life of proposulfuron in corn is only 6 hours, and corn is still safe when treated with 2-4 times the recommended dose. In corn fields, the recommended dosage is 5-15g (a.i.)/h㎡ [0.33~1.0g (a.i.) per acre]. When used, there will be no adverse effects on subsequent crops, but sweet corn, popcorn, sticky corn and seed production fields Not suitable for use.
Control objects:
Can control most annual and perennial grass weeds and broadleaf weeds such as cyperus, sedge, etc. in corn fields
⑴ Apply the pesticide at the 2-4 leaf stage after the emergence of spring corn or the 2-4 leaf stage of weeds (after basically all emergence). Within 7 days after application, try to avoid using organic pesticides, otherwise it may cause phytotoxicity in corn. The pesticide should be applied before the 4-leaf stage. If the corn exceeds the 4-leaf stage, phytotoxicity will occur if used alone or mixed with corn
⑵Summer corn: mainly used to control annual grass weeds and broad-leaf weeds. Grass, the dosage is 1.2-1.67g (a.i.); spring corn (Northeast): mainly used to control annual weeds such as barnyardgrass and amaranth retroflexus, the dosage is 1.2-1.53g (a.i.)/acre. Adding 0.2% nonionic surfactant (organic silicone, detergent or washing powder, etc.) plays a key role in maintaining the effectiveness and improving the activity of the agent.
