Nicosulfuron Pesticide Grade

Smoke its cycling is found ishihara industry co., LTD, Japan in the late 1980 s with the United States dupont, joint development of sulfonylurea systemic herbicide. [1]

Weed control characteristics

Properties: single product is colorless crystals. Melting point of 172-173 ℃. Soluble in water. Solubility of 18 g/kg in acetone, ethanol, 4.5 g/kg.

Smoke its cycling is systemic herbicide, for weeds stems, leaves and roots in conduction, then cause the stagnation of sensitive plant growth, stem leaves faded green and die gradually, generally 20-25 days to death, but in the case of low temperature for some perennial weeds need to be a long time. 4 after bud leaf stage before applying pesticide effect is good, the seedling age applying pesticide efficacy. Before the drug has a bud herbicidal activity, but activity is relatively low after bud.

Its main features are:

1, this product is a special process of vegetable oil, suspending agent, usually using corn oil or industrial-grade soybean oil as solvent, not only of the weed control effect, enhanced the grass can administer at the same time, don't have to wait for the rain.

2, readily availability, 5 to 7 days after applying pesticide weed wither began to change color.

3, the effect is good, the product not only has the very good stem leaf kill grass effect, also have certain soil sealing effect, after 30 days of weed control effect.

4, good rain resistance, eight hours after the rain will not affect the efficacy of applying pesticide.

5, good security, under the condition of normal corn and crop after will not cause any adverse effects. [2] but not excessive use, excessive use can cause to the small crop seed germination rate reduced.

Applicable crops: maize.

Matters needing attention

 editor

After applying pesticide observation, corn leaf had mild faded green, but it can recover soon. Corn under 2 leaf stage, more than five leaf stage is relatively sensitive, prone to the adr. Corn drug sensitive varieties have a blowout of sweet corn and corn. After processing of corn with organophosphorus pesticides drug sensitive to this. When applying pesticide, the temperature is controlled in 20 ℃, humidity above 60%, within 12 hours after applying pesticide without rain, play in favour of efficacy.

___________ different corn varieties have difference on the sensitivity of the smoke its short cycling, its security order for horse tooth type > hard corn > > burst sweet corn. Plain corn 2 period before and after 10 leaf stage, is sensitive to the drug. Blowout of sweet corn or maize is sensitive to the agent, do not use.

2. The crop after wheat, garlic, alfalfa, potatoes, soybeans, etc without residual phytotoxicity; But for Chinese cabbage, beet, spinach, cucumber, sunflower, and we have the adr. In food dishes intercropping or rotation, should do well in phytotoxicity of crop of vegetables after test.

3. When mixed with 2, 4 - drops, should avoid liquid drift to other nearby broadleaf crops, and spray to dedicated.

4. With organophosphorus reagent processed corn is sensitive to the drug. The use of two drugs interval for about 7 days. Smoke its cycling can be blended with strain rate.

⒌ administer 6 hours after rain, had no obvious effect on effectiveness, not heavy.

Pictures in the corn maximum residue limits (called simply MRL) of 0.02 mg/kg, the highest use dose of 4 g per acre (active ingredient), application number 1 time, most safety interval for 30 days.

But to avoid direct sunlight. Separated from seed, seedling, fertilizer and pesticides placed, as far as possible placed in low temperature and dry place seal preservation.
