Herbicide Combination Atrazine 75% + Nicosulfuron 4% Wg/Wdg
Atrazine is a selective systemic conductive pre-emergence soil treatment herbicide that can also be used as a post-emergence stem and leaf treatment. It is mainly absorbed by plant roots and conducted upwards, inhibiting plant photosynthesis and leading to plant death. Atrazine has a broad herbicidal spectrum and can control a wide range of annual grasses and broadleaf weeds.
Nicosulfuron is a systemic herbicide that can be absorbed by the stems, leaves, and roots of weeds. It is then translocated within the plant, causing sensitive plants to experience growth stagnation, chlorosis, and gradual death. Under normal conditions, this process takes about 20 to 25 days, but in cooler temperatures, certain perennial weeds may require a longer time to die. The herbicide is most effective when applied before the four-leaf stage; its efficacy decreases when applied to larger seedlings. This product also has pre-emergence herbicidal activity, although it is less active than its post-emergence effects.
Features of Nicosulfuron
- Fast efficacy.
Generally, after application, weeds can show changes in color and wilting within 5-7 days (and will be completely dead within 20-25 days after spraying).
- Good residual activity.
Nicosulfuron is a systemic, foliar herbicide. After foliar spraying, it remains effective against weeds for up to 30 days.
- Good rain resistance.
Rainfall occurring 6 hours after application has no significant impact on the efficacy, so re-spraying is not necessary.
- Relatively safe.
Under normal conditions, nicosulfuron does not cause adverse effects on corn or subsequent crops. However, care must be taken to avoid over-application. Excessive use can lead to injury in corn and potential issues with subsequent crops, such as reduced germination rates or residue problems.
Application of Atrazine
1. the use of corn fields: summer corn in the sowing of seedlings before the use of drugs, soil organic matter quality of 1%-2% of the region, per mu with 50% wettable powder 150-200 grams, or 40% of the suspension of 175-200 ml; soil organic matter content of more than 3%-6% of the region, per mu with 50% wettable powder 200-250 grams, or 40% of the suspension of 200-250 grams , use the lower limit for sandy soil and the upper limit for clayey soil. 1-3 days after sowing, spray the soil surface evenly with 30 kilograms of water. Use the medicine after corn emergence, the appropriate period for corn 4 leaf stage, weeds 2-3 leaf stage; sandy soil with low organic matter content, use 50% wettable powder or 40% suspension agent 200-250 grams per mu. Spray 30-50 kilograms of water. Spring corn with 40% suspending agent 200-250 ml per mu, add 30-50 kg of water, spray the soil surface before the seedling after sowing, mix the soil after the spring drought medicine, or moderate irrigation. Or make stem and leaf treatment at the 4-leaf stage of corn. Corn and winter wheat continuous cropping area, in order to reduce or eliminate atrazine on wheat drug damage, available atrazine reduced and grass net Zin, Lasso, Duer, 2,4-D butyl ester, companion of the land agricultural, green wheat Long herbicide mix.
2. Sugarcane field use: 5-7 days after sugarcane seeding, weeds partially out of the soil, per mu with 50% wettable powder or 40% suspending agent 200-250 grams, add 30 kilograms of water, to the surface of the uniform spray.
3. Tea plantations, orchards, vineyards use: 4-5 months field weeds sprouting peak, the first has come out of the ground grass and overwintering weeds rowing, and then per mu with 40% suspending agent 250-300 grams of 40 kg of water evenly sprayed on the surface of the soil.
4. atrazine is pre-emergence soil treatment herbicide, can also be post-emergence stem and leaf treatment. The use of drought has a greater impact on the efficacy of play, mainly in the role of dicotyledonous plants, focusing on closure, the effect on the big grass is relatively unsatisfactory.
Application of Nicosulfuron
The best time to use Nicosulfuron:
- During the 3-5 leaf stage of corn (when resistance is strongest and less prone to phytotoxicity).
- When annual weeds are at the 2-4 leaf stage (weeds are relatively small and easier to control).
- Before the 6 leaf stage of perennial weeds and when most weeds have emerged, the application will be most effective.
(1) Ordinary Nicosulfuron without a safener:
It is advisable not to use it when corn is below the 2 leaf stage or above the 6 leaf stage, as it is sensitive and prone to phytotoxicity. If it must be used at more than 6 leaves, it should be applied as a directed spray to avoid contacting the growing point and causing damage.
(2) Nicosulfuronwith a safener:
Compared to ordinary Nicosulfuron, this formulation is relatively safer and can be used after the 5 leaf stage. However, the effectiveness of weed control decreases as the application is delayed, so it is recommended to use it during the 3-5 leaf stage.
